ABSTRACT
Beny Bastiawan (2005). Simulation Model For Tuna and Shrimp Production in Indonesia. Under the Supervision of Kudang Boro Seminar and Hartrisari Hardjomidjojo
This research was conducted from April 2004 – January 2005 in bogor, West Java – Indonesia. The area of study is the Sea Waters at Indonesia especially on the Region Management of Fisheries of Indonesia.
The General objective of the research area : 1. To recommendation a strategy of Indonesia to release commerce issue of marine fish product in facing up the international forum, 2. To estimation of Indonesian position in related to free trade issue in the sector of marine fisheries.
The input data are collected from various source among other 1. the Ministry of Marine affairs and Fisheries of Indonesia. 2. Statistics Indonesia of The Republic of Indonesia (BPS), 3. Center for Oceanography Research of The Indonesian Institute of Science ( P2O LIPI) and others.
The analysis method used the simulation model by Dynamic modeling where we focusing on sub model such as Buffer Stock, Production, Exploitation, demand and Supply. Also the Method for the research of Simulation model for Tuna and Shrimp production in Indonesia are several aspects that is from research of natural growth of fish population ( Tuna and Shrimp) natural added from illegal fishing influencing with growth of fish resources (Tuna).
Later; Then from fish resource population ( Stock of Fish resource) existing this hence seen ability of Tuna and Shrimp production and related ability of effort capturing of fish resources ( Catch Per Effort Unit) in tuna production and Shrimp. As for the Fish Resource concern of ability of fish production is very influence by capacities of Maximum Sustainable Yield in each of Fish resources (Tuna and Shrimp) making this Maximum Sustainable Yield is limitation of Exploitation of Fish resources.
Henceforth model will be tried validation model to see how accurate of itself model in simulation. And in the end will be seen how big and make everlasting him exploit fish resources related to Maximum Sustainable Yield between Exporting and Import. To see the mention of Simulation model than some scenario alternative those are scenario by 1.) Condition of existing where each the variable of relating with the data existing data of this matter was we assume as scenario which still moderate; 2.) Condition where the output is productivity become the target of maximally assigned value for Maximum Sustainable Yield most optimum tolerance range; 3.) Related with the conservation concept where expected for the fisheries resource remain to make Sustainable but the production output of seen did not maximum.

INTRODUCTION
1.1. Background
In order to support policies to perform the Basic Strategy Compilation
of Indonesian Economic Position policy in Marine and Fishery Area In
Multilateral Commerce System Frame World Trade Organization (WTO),
some policies and steps could be taken by Government in supporting
some policy strategies, for example:
a. Inventory Problems of marine and fishery area in international trade
forum especially in Tuna fish and Shrimp.
b. Inventory Strategy of Indonesian Economic Policy Marine and
Fishery Area, Industry and Commerce zone area of corporate world
in Multilateral Commerce System Frame – WTO
c. Forming the development model of Indonesian economy in marine
and fishery area as elementary strategy compilation reference.
From above policy Strategy therefore third point for the “Forming the
development model of Indonesian economy in marine and fishery area as
elementary strategy compilation reference”, represents the study
requirement analysis for the needed quantity.
As Model requirement will be conducted in this empiric, hence it needs
various quantitative data from the used parameters and variables. In the
dissimilar variables, which are not needed by quantitative data of
valuation to the parameter. By conducting monetary supervision from
available fishery data, internalizing various variables hopefully can be
performed to structure more hierarchical development model.
As fundamental attention that Indonesia has the biggest territorial
waters area in the world with the fishery commodity owning value export
like Tuna and shrimp, it needs the elementary strategy in facing up the
consultation – related to WTO consultation in the fishery sector. This
matter is significant to maintain the product competitiveness and secure
the high value of fishery resource capacities.
Considering that this elementary strategy compilation refers to the
system of WTO and is constituted by simulation and model, hence its
specialty in the effort management of marine resource and national
fishery requires the existence of forming modeling system. This Modeling
system basically represents the sub-system model of Indonesian economy.
Refer to the valuation mentioned above, the stock resources on the marine
and national fishery represent the step of initial model forming. In this
context, the stock is including mutation of stock resource, the affect of the
redundancy from the mutation stock and contribution of mutation activity
1.2. Objectives
This study is aimed to develop the economic policy strategy of
Indonesia in facing up the International forum in area of marine and
fishery.
From the inferential above opinion, the objectives are:
a. To recommend strategy of Indonesia to release commerce issue of
marine fish product in facing up the International Forum.
b. Stipulating estimation of Indonesian position related to free trade
issue in the sector of marine and fishery.
This study result will be strategy model of Indonesia to respond

LITERATURE REVIEW
2.1. The Commerce of Multilateral-WTO
World Trade Organization (WTO Agreements signed in Marrakech in
1994 is purposed to create fair commerce and more market oriented one
through developing tied and multilateral agreements. One of the main
principles in rule implementation of WTO agreements is the
non-discriminative which means not treat distinctively the industry
domestically or broadly. Recently, fishery sector is not included in
Agreement on Agriculture, so the solution in WTO forum always tends to
enter the non-agriculture group. Though for Indonesia, during the time,
fishery sector represents one of policy dimension from agriculture policy
in general. Consequently, benefit from free trade in agricultural sector
which in Agreement on Agriculture (AoA) comprises fundamental pillars:
(a) reduce all form of the exporting subsidiary; (b) repair access to the
market; and (c) reduce domestic support; cannot be enjoyed by commerce
mechanism of available fishery result.
Before KTM WTO IV Doha, commerce of fishery yields was discussed
more in Committee Sanitary-PhytoSanitary (SPS) and Technical Barrier
To Trade (TBT). From early 2002 it has been studied also in Committee
on Trade and Environment (CTE) and Negotiating Groups on Rules and
Negotiating Groups on Market Access for Non Agricultural Products
especially those concerning Agreement on Agriculture (AoA), Indonesia
had better prepare settled strategy so that the negotiation in fishery sector
could increase export stream of fisher products and yields, and provide
beneficial advantages for thee development of fishery industry in future.
Globalization era brings the export to the larger opportunity one but at the
same time we should watch out our domestic market because imported
products might flow tremendously into the domestic market. Fishery
yields produced in many countries; as a result the competition is
increasingly tight because there are more and more perpetrators in
international market. Hence, only few products of competitiveness win
the emulation. Advancing competitiveness is absolutely needed through
efficiency advancement at any levels of efforts, advancement the quality
of human resources (skills and professionalism), and development of
resource base products having comparative excellences.
On the other side, Indonesia as biggest archipelago country in the
world broadly region of territorial water for the width of 5, 8 million km2
(3 / 4 region represents the region of physical water ecosystems), more
than 17.500 islands and 81.000 km second biggest coastline after Canada,
owns an sustainable potency (Maximum Sustainable Yield = MSY)
fishery resources yields from 6,4 million tons per year (BRKP-DKP,
2001). From the sustainable potency, almost 5,14 million tons per year
derives from territorial waters and archipelago, and 1,26 million tons per
year from Indonesian Exclusive Economic Zone (ZEEI). If permitted
MSY, hence the fish resources yields equal to 5,12 million tons per year
will be available. Based on the record of fishery capture, in the year 2001
number total capture is 4,069 million tons (BPS, 2001). It means that
usage levels of fishery resources in Indonesia recently reaches 63,50%. It
also means that the exploiting opportunities equals 36,5% or at least
ranging from 1,12 to 2,4 million tons per year with the productivities rate
assumption that the capture is as many as the previous years.
If manageable exploiting potency we have for the sake of the national
interests is production bases which are regularly established, particularly
to develop distribution bases mainly in the frame of international
commerce, many barriers are found. The barriers might be grouped into
tariff barrier, non tariff and other issues. The emerging tariff barrier is the
existence of tariff escalation discriminative attitudes. For instance,
European Union apply tariff to 24 % for the canned Tuna cultivation,
20% for canned shrimp and 25% for Mackerel. Meanwhile, the US
applies the tariff to 34% for canned Tuna in the oil. Another
discriminative treatment is the customs tariff liberation for the imported
canned Tuna from the countries associated in ACP in EU market and in
pouch tune from the counties associated in Andean Pact found in the US.
Meanwhile, until recently Indonesia is said to be liberal in applying tariff
for fishery yield and also said to be low, i.e. 0 – 5%, with 3,5 %
averagely, even it does not apply escalation tariff.
Other technical borders in intenational commerce of the fishery yields
microbe, pathogen, hystamine, heavy metal and hormone. Even, the
European Union tend to use the complex food safety condition. EU
deliver embargo on the exported shell products coming from Indonesia
due to we have not yet been monitoring system on waters sanitary which,
in EU version, belong to our responsibility. Meanwhile, US also apply
various requirements that might be a hiden barrier, such as the obligation
to use TEDs, or ‘accuation’ of using longline and gillnet on capturing
Tuna. This usage is pressumbably endangesr the seabird and leatherback
turtles.
Although recently the export comodity of marine and fishery have not
yet become the main commodity, but the strategic environment and
modality, more over the competitors countries are in short of fishery and
marine resources, Indonesia has opportunity to be an outstanding
industrious country of fisheries in the world.
Therefore, Indonesia have to take several strategics steps to safe
(safeguard) marine and fishery commodity from the probblems in this
sector, either in recent time or future, particularly those related to world
commerce in the frame of World Trade Organization (WTO) or in the
frame of regional Free Trade Area (FTA), in which Indonesia belongs to
it.
Indonesia is one of the members of Agreement Establishing WTO and
had also rafied Agreement Establshing the World Trade Organization
with UU no 7 in the year of 1994 about legalizing Agreement Establshing
Paper no 3564) desepite Indonesia did not ratify the entire agreements
ehich are Annex of Agreement Establishing the WTO.
By signing and ratifying the WTO, every member state, including
Indonesia, has the legal rights not to be treated discriminatively by other
members in treatment of tariff area, non tariff as well as the treatment in
national. Besides, member states of WTO is also entitled to fight for the
authority, for example, through solving dispute of WTO and blame the
other state policies presumably harmful for the interests of developing
countries in many relevant forums of WTO.
For the state which is ready for globalization, accordingly all
negotiations resulted from WTO forum will be the opportunity (big
opportunity), for example, to reduce tariff. Eliminating trade barrier in
other countries can give big opportunity to the export of the developing
countries, including Indonesia. However, on the other side, WTO does
not only create opportunity, but also threat. System of world commerce
will be complicated and tightly regulated. Thereby for state which is not
ready, the existence of tight regulation in WTO exactly will pursue the
state commerce growth. It is impossible that various agreement of WTO
is utilized by developed countries to protect their domestic interests from
coming import. Other significant advantage is that developing countries
might determine the consultation members in international commerce for
countries. This matter will not occur if the developing countries are not
under the system WTO
2.2. Resources Valuation
The experience of resource valuation is a process to calculate the
value of resources, both in the form of product and commodity of
environmental service in term of monetary. The valuation process is
conducted by various methodologies of monetary valuation to calculate
the value utility and non utility value from environmental and natural
resources.
Valuing the environmental and natural resources valuations is unlike
assessment of service and goods. Usually assessment from goods is
visible from price determined by market, where the process represents the
condition supply and demand. Environmental and natural resource, such
as forest and coastal area countable their values from the trading process
in the market. Unfortunately, the values only show the partial value of
natural and environment resources. Environmental and natural resources
basically produce more products and services than what traded in market
are. For example, forest resources generally are merely valued for their
wood, logarithm or plywood produced. For coral reef, values are upon the
captured fish. Presumably, it is due to the products are relatively easier
and traded in the market.
Meanwhile many matters are left uncared, that forest and coral reef are
by erosion occurrence if the resources are not available. For instance,
forests prevent the floods by permeating water, while coral reef serves as
coastal prop from wave. In this case, potential expense obviated can be
considered the accepted benefit.
Two main procedures in valuation environmental expense and benefit
are:
1. Determining physical impacts and their relation,
2. Valuing the benefits and affects in term of monetary.
The first step is to determine the potential impact that may happen to
natural if there is ‘accident’ environmental. This procedure is usually
done by the experts of engineering and ecology. Meanwhile, the second
step is performed by using economic analysis approach which repeatedly
requires the proficiency of discounting cost and benefits for the future.
2.3. Economic valuation of natural Resources
Economic assessment is not representing independent ethics
assessment, like the following statement:
“Appropriate value for natural resources given for variety conservation
is possibly pushed by caring of moral or ethics. For example, it is pushed
by interest of others prosperity or other species. Caring moral and ethic
are, like feeling and choice could be translated as desire to protect the
biological variety” (Perrings Et al 1996 pp 829).
In comprehending natural value and environmental function, economic
Value (NET). NET is divided into two parts, those are the assessment to
utility and the one to the non-use value (passive use).
Equation 1: Total Environmental and Economic Value
Use Value Passive or Non-use value
TEV = F( DUV, IUV, OV, QOV + BV, EV) TV = G(PV + TEV)
Non-anthropocentric
Instrumental value
Where :
TV = Total Environmental Value TEV = Total Economic Value
DUV = Direct use Value
IUV = Indirect Use Value
OV = Option Value
QOV = Quasi Option Value
BV = Bequest Value
PV = Primary Value
EV = Existence Value
2.4. Modeling
In Order to support the basic strategy compilation of Indonesian
economic policy position on marine and fishery areas in the frame of
system of multilateral commerce – WTO, it is required simulation and
model functioned as sub-system models from economic model or
Indonesian economic development.
The model approach to be developed in this study is conducted with the
pattern of model development based on computer modeling, from simple
to the complex to support and be used as instrument (tools) in policy
analysis especially at basic strategy policy of Indonesian economic politic
position of marine and fishery areas, by calculating and analyzing the
policy mainly related closely to mathematic programming. Prediction
tendency and other instruments are linked to Analysis Instrument System.
Definition of the model refers to the definition that the model is a
simplification of the real situation found in the real world. The real and
complex events in the real life could be defined as a tern of event. In this
case, each definition in the real life is selected into procedure mechanisms
in an operation from a system where those mechanisms are parts of the
model.
Model is implemented to accomplish the complex problems of the
system that develop simplification and comparison from the real situation.
The pattern of modeling approach in this study is performed with the
approach pattern of Dynamic System Model or “Dynamic Modeling
responding a complex system to solve the economic, ecology and social

3.3. Logical Frame
In this study implementation will follow the logical framework such
[image:38.595.118.528.371.631.2]as found in figure 2.
Figure 2. Logical Frame Work
In order to follow and make balance the various growths that
happened in multilateral commerce system in World Trade Organization,
products in global market. To reach this target, presumably Indonesia
need to determine the basic strategy of economic policy position of the
marine and fishery sector that can be the guidance in so different
multilateral commerce consultations. In determining the basic strategy of
this economic policy position, it is important to know various external
factors which are immeasurable, opportunity and threat, where study
focus will be emphasized on the agreements which have been agreed on
WTO related to fishery sector.
Besides, it also finds various resistances internal factors and
challenges owned and faced by fishery sector domestically, both in the
form of resource potency and supported infrastructure, and also in the
form of political policy peripheral in regulation and legislation.
[image:39.595.100.516.430.694.2]
In the implementation of fishery resources to economy, it needs the
existence of experienced effort resources valuation that can be an input
for decision making about economic development in fishery sector.
With the existence of this input, accordingly macro economic model
sector of marine and fishery in national can be compiled as an empirical
base for determining the position of economic policy of fishery sector in
global commerce. Through this model we can prepare various policy
scenarios to win the global market.
3.4. Legal Aspects
The Analysis conducted refers to three variables, those are (1) UU of
Fishery No. 31 Year 2004, (2) Agreements of World Commerce System
(World Trade Organization), (3) Resources of Indonesian marine and
fishery. The analysis focuses on 5 important pillars, (1) Policy pointing
to resources (resources, such as fish and others); (2) harvester; (3)
Industry managing fishery resources in framework of added value and
commerce (industry and trade); (4) Consumer (consumer); and (5)
Continuation of environment (environmental aspect / preservation).
Among the three variables placed on the existence of relation among
UU Republic of Indonesia, International Convention, effect the
regulation product to exploit and manage resources of marine and
fishery.
Since its basic assumption is ratified by WTO (Final Multilateral Act
Embodying the Results of the Uruguay Round of Trade Negotiations)
by Indonesia, Indonesia have bounded it self for the comply of the rule
in regime WTO such as: General Agreement on Trade and Tariff,
Agreement On the Application of Sanitary and Phytosanitary,
Agreement On Technical Barriers to Trade, and Agreement on
Safeguards. Compilation of legislation Product after ratification,
including of Fishery Regulation, should consider the basic principles of
WTO.
3.5. Modeling aspect
In order to support the basic compilation of Indonesia economic
policy position in the area of Marine and fishery in multilateral commerce
system frame, therefore a functioning model and simulation are required
as sub-system model from economic model of Indonesia.
The model approach to be developed in this study is conducted with
the pattern of model development based on the computer model compiled
from simple model up to complex one to support and to be used as tools
in policy analysis. By having calculation analysis, the policy especially in
the field of economy and other related components can be implemented
by Mathematic Programming. It is also possible to predict the tendencies
Methodologies are developed by utilizing dynamic system for
example:
- Identify the problems
- Develop explanation on problems themselves
- Design and develop; build the model of computer simulation in
solution from problems root.
- Conduct the study and try to form the model itself for
monitoring the behavior at the real life.
- Result from this model will be made as policy alternatives to
assist trouble-shooting.
- The result the alternative hopefully can be utilized as a support
in giving solution.
According to developer of dynamic system model (Jay W. Forrester),
explaining application developed with the system of dynamic model earn
the application into problems resolving, such as :
- Scheme and design the area of the effort
- Public policy and management
- Model of medicine and biology
- Environment and energy
- Social science and nature science development.
- Dynamic having the character of decision making.
- Complicated problems and the character of the non-linear
dynamic.

Scheme and model development in this study are conducted by an
approach pattern drawn in Figure 4. They are also prepared with the
supported phases, such as :
1. Data collection, Various relevant information and data in this
study will be collected from various different sources to be used as
[image:43.595.135.517.70.436.2]and finally determining the policy on economic position in
multilateral commerce.
2. Data Analysis, Data gathered will be analyzed based on to
requirement, particularly to equalize the consistent usher of the
obtained variables with optimal result. If needed, to some data
gathered adjustment are performed.
3.7. Developing Model
One of the important parts of this study is model development
representing moderation process from system of incoming effects on the
real life in which it can be analyzed easily. From this, various model
related to each variable influencing each other are visible. Later analysis
on how an influence happening in one particular variable in the case of
change from other variables is conducted.
The developed model will represent the network from various sub
models at fishery sector, where in this case the more focused one on
fishery resources becomes commodity in international trade especially
Tuna and Shrimp.
This model development will use software available to water down
the study execution process. Software to be used is Stella-I think and its
ability is reliable. This software is applicable to develop or build the
model, make the simulation in various scenarios and to estimate the
3.8. Implementation phase
In this study, several phases will be implemented as follows:
• Global commerce Literature study, fishery sector. This Phase is to
know various rationale and growth that happened in global commerce
area, and the other relevant with fishery sector.
• Macro Economic data collecting, this Phase is aimed to observing
various relevant macro economic data with the resource of Indonesian
fishery traded in global market, especially from export and import
side.
• Data collecting of fishery resources (Tuna and Shrimp) are necessary
to complete various variables from developed model, to see related
usher to the variable.
• Valuation of fishery resources (Tuna and Shrimp) to assign monetary.
• Basic model development using Modeling builder represents the
phases to chain the related variables.
• Multilateral commerce variable formulation represents the phase in
various low aspects toward International Global Trade in fish
resources (Tuna and Shrimp).
• Evaluation model
• The time of entire models formed have real correction; model has
earned better operation.
• Determination of Scenario
• Analyze the result of simulation
• Write the report of the analysis result.
IV.
RESULT AND DISCUSSION
The goals and target of this research are to develop the frame of Model in the
structure with two (2) subs Model:
1. Sub Model of the fishery resources divided into Tuna and Shrimps
2. Sub Model in the macro economy divided into sub Export and import
where they are combined in International Trade. The Aspect of those matters is
legal aspect (The Act of Fisheries and World Trade Organization agreement).
4.1. The Legal Aspect Perspective
Free trade emphasizes more on freedom in goods current and services.
In the case of marine and fishery products, emulation in open commerce
makes two product levels; those are raw material products such as fresh
fish and frozen fish, and product of process, such as canned fish. The raw
material sectors, emulation happened in the context of comparability
excellence. Nations with high raw material potency tend to exceed their
roles as fresh fish or frozen fish supplier. A problem is that fish resources
are not only limited to territorial sea, but also free seas, outside exclusive
economic zone. If fisherman’ ship captures in free sea water, hence
captured products can only be claimed as coming pertinent ship Flag
State. In this context, Indonesia can give facility to the fisherman’ ship to
Unfortunately, in international context of this case, it has not yet been
obtained certain arrangement. Until this article is made, facilitation trade
is not yet agreed in the negotiation of Word Trade Organization (WTO).
If Indonesia can give facility to fisherman’s ship of this free sea water, it
is not impossible that Indonesia get benefits from this activity, at least
from the sector of marine product collection and labor port.
However, the more important thing is how to give emphasize on
fishery policy in Indonesia. The policy should be put down to manage
available excellence, whether that of comparability or competitiveness. If
it is realized that excellence is more dominant on comparability than the
excellence of competitive, hence policy direction has to emphasize more
on how to manage comparability excellence in the form of properties of
fish resources and others. It is later aimed at making added value. It
means that Indonesia have to conduct efforts to be properties so that the
resources can be turned into economic potency in the form of processing
products having the high competitiveness.
In this context, policy of Indonesian fishery is aimed at accomplishing
international standards, such as agreed on pursuant to Agreement
Application Sanitary Phytosanitary and The Agreement on Technical
Barriers Trade, and Agreement of Safeguards. In meeting international
standard, product competitiveness of Indonesian fishery process in the
global market will progressively increase. In Article 3 sentence (2)
Agreement on Application Sanitary Phytosanitary, it is expressed that
“Sanitary or phytosanitary measurement which confirm to international
human being, animal or plant life or health, and is presumed to be
consistent with the relevant provisions of GATT Agreement 1994”.
When the Law of the Republic of Indonesia (UU) of Fishery
emphasizes more on resources protection of small harvesters,
consequently effort to do is how small harvesters can fulfill such
international standard. In this context, the synergy among the persons
responsible for this effort or small farming fishermen becomes relevant. It
means that the same activities between small fisherman and processing
fish industry become one of alternatives to improve comparability
excellence become competitive excellences. Hopefully small fishermen
become suppliers for fish processing industry to fulfill capture standard or
marine culture agreed or determined by the stakeholders. The
Government can give facilities related to agreements with this matter.
It is necessary realize that the system of free access to market adopt
beneficial WTO agreements to have advance technology and capital.
They relatively fulfill standards specified by state members of WTO and
international standard, for technical standard and standard in frame of
sanitary and of Phytosanitary. If it is hoped that Indonesia exceed the
negotiation to area commerce of fishery products, thus beforehand
Indonesia have to strive accomplishment of international standards which
are applied in the members of WTO.

exploit port of Indonesia as commerce bases of such captured products.
Unfortunately, in international context of this case, it has not yet been
obtained certain arrangement. Until this article is made, facilitation trade
is not yet agreed in the negotiation of Word Trade Organization (WTO).

When the Law of the Republic of Indonesia (UU) of Fishery
emphasizes more on resources protection of small harvesters,
consequently effort to do is how small harvesters can fulfill such

In the modeling, the important step is determining parts of the system
and how the available components in the system are linked. while
determining, it is necessary for the modeler to have experience and
intuition. Further more, it should be supported by sufficient data both
primer and secondary. The analysis system in the process of
decision-making, which is using operating research (System Analysis), consists of
five steps:
• Identifying the problems
• Making the model
• Analyzing the model
• Validating the model
• Implementing the model
Generally, the steps of making the models can be classified into
Modeler should decide how simple or complex to make the model. If
the model is too simple, it might be inaccurate to describe the condition of
the real system. On the other hand, if it is too complicated, it might be
unmanageable.
The comprehensive understanding of the system and the problem will
facilitate the modeler to make diagram models properly and increase the
opportunity that the models constructed is nearly the same as the real one.
Modeling procedures comprises eight steps:
• Defining the problems to be analyzed
• Determining scope of the problems, which are faced, based on the
limitation of time, space and components of the models :
• Collecting the needed data
• Making conceptual models
• Composing mathematics equation for each function of the
modeling
• Verifying or proving the models made
• Analyzing the sensitiveness of observing the changes happened to
the parameter
• Calibrating or proving the validity of the models in the field by
conducting experiments.
4.3. Assessment of Fisheries Resources Potency
Fishery study concerning various calculation of and statistic of
mathematic to make prediction concerning various reaction of population
to a number of choices of alternative management. Target of base of
management of fishery is to assure the obtaining of going concern
production of fish stock during old ones to improve prosperity of
fisherman economics and social and industry fishery area.
Potency study for the stock of assessment is sometime seen as
biological discipline to estimate potency. In fact a stock study of activity
which is wider
The first and important is study of stock try to comprehend fishery
dynamics. Base on the fact that fishery is entities the dynamics, to always
respond all management action and also to intrinsic factor fishery of
itself. Study of fisheries resources which have gone forward not merely
working for to make various prediction having the character of static
regarding everlasting potency, also have to got mixed up with to make
prediction concerning expected concern during come to response change
of policy and concerning how the wisdom have to structure that can
accommodate a number of difficult changes of prediction but the
occurrence of do not earn to be obviated.
Fisheries more than complex and from not only capturing of fish.
The Fisherman and Industry in in the field of fishery is important
component of system of dynamic in study and fishery of stock have to
consider Fisherman and Industry to response various regulation and
Potency ( fish stock) cannot controlled directly like in agriculture, but
fish stock influence by activity of human being and many matters efficacy
of fishery very from status of itself fish stock.
For that hence policy concerning fishery have to consider the
condition of from fish stock and also given respond to various addressed
action to related stakeholder. As a preview of degradation of fishery
capturing to specify a number of regulations as a mean to overcome
abundant capturing ( over fishing) so that enable for stock the purpose to
be high capturing.
In this case role of government expected can know influence to be
generated by management action to fish stoke and also to period to come
haul. Many other organizations need knowledge concerning capturing
type able to be yielded by ship to fish stock, and from here to fish capture
still going on. For example in the stock of fisheries when they have
stressing from the growth over fishing, that is mean the resources of
fisheries not yet growth. The juvenile of fisheries could be get caught in
the mean time they didn’t growing up. The growth of this case could be
loss rate from the stock of fish resources.
Therefore expand study work frame of stock, also relevant aspect of
fishery science and stock study continue to expand and change. In Reiger
( 1976) illustrated for assessments of fishery can be preview on a table
which is growth levels indicated and exploiting of fish resources in
Is caused most areas fishery of global in motion toward that, namely
most of resources in a region have exploitations moderating or fully. This
matter cause potency study ( stock) have to be related to storey; level of
end of more based on the ecosystem whole and also interaction between

In conducting for study of amount of fish stock and influence of

exploited mathematics hence complexity of real situation can be replaced
Models like this can be used to represent amount for example
population what abundance population, individual measure relation and
fish between amount. Production models, treating a fish population as a
single unity which influenced by simple regulation of improvement and
degradation of biomass. With this models enable to be made analysis if
just very few information, namely catch, abundance, and amount of
fishing effort.
4.4. Modeling Stages
For the supporting development of simulation study model to the
availability of fish resources ( Tuna and Shrimp), require to run
simulation for this model. Supporting variables this from sub of level
model Buffer Stock, Production, Exploitation, Supply and of Demand
side.
4.4.1 Growth Population of Fisheries Resources
As data base for simulation model hence especial matter to
prepare data of availability of fish ( potency stock) from existing
covering tuna resource and shrimp which is in data of stock fish from
all Region Management of Fishery ( WPP) which exist in Indonesia.
Potency data of fisheries resources by continue and is totally
required by various entrepreneur of fishery area and to all investment
reference in making policy for example for the give of permission is
effort capturing of fish qualitative and quantitative.
Up to ready in this time potency data of fish resources still in
problems. This matter because of not focused on activity of study
survey of stock fish by national. Also in research into which done
various institution by snatches and isn't it only in some areas. This
fact have to look for the way study of stock fish which was program
and various related institution which was coordinate by
