INTRODUCTION
Sharks and rays (elasmobranchii) species are known for their relatively low
fecundity, length at maturity on adult phase, and slow growth. High potential of
sharks and rays make them a valuable target for the community, therefore
sustainable management approach to conserve and preserve the species is
recommended. In Indonesia, management of sharks and rays are based on the
National Plan of Action (NPOA). A strong regulation and regular and transparent
evaluation is needed to successfully implement NPOA. Effective management of
sharks and rays need a strong support and commitment from all stakeholders
through sustainable financing system and program. NPOA of sharks and rays was
established in 2010 and within 5 years, Indonesia shows its commitment by
producing regulations such as full protection for Whale Shark (2013) and Manta Rays
(2014). Indonesia continues the commitment and consistency to the second period
(2016-2020) by formulating nine main strategies based on previous NPOA
evaluation and commitment to international management of Sharks and Rays.
Since 2013, the cartilaginous fish group has been a widespread international
issue, especially following the introduction of several species of sharks and manta
rays in Appendix II CITES. This is due to the high exploitation of various sharks and
rays, both as main target and bycatch. Sharks exploitation in Indonesia commonly
happened in potential areas of nursery ground, such as coral reef areas, shallow
waters, or in feeding ground such as estuary areas. This can lead to a rapid decline
in the population of sharks and rays, in the expense of a long time recovery.
Limited scientific data and information is the classic challenge in
implementing maximum effort of protection and conservation program. Moreover,
related research of sharks and rays that hopefully will fill in the data gap remains less
popular in Indonesia. The first Indonesian Sharks and Rays Symposium in 2015
gather recommendation for policy through policy brief, such as; 1) Establishment of
Sharks and Rays Working Group that collect databases of sharks and rays species,
v
and facilitate human resource capacity building in the data collection system; 2)
Strengthening sharks and rays products' traceability system, as well as developing
best practice guidance to encourage the development of shark and ray ecotourism;
3) Encouraging the protection of important habitats. In 2018, Indonesian Sharks and
Rays Symposium is back to gather the latest sharks and rays scientific researches
conducted in Indonesia, in respond to the needs of sharks and rays sustainable
management, particularly for species listed as “threatened with extinction” by IUCN,
and species with growing concern at the international level like CITES and RFMO.

FROM TUNA LONGLINE IN THE INDIAN OCEAN Dian Novianto*, Prawira A.R.P Tampubolon, Budi Nugraha
*Pusat Riset Kelautan *dianovianto78@gmail.com ABSTRACT
The Blue shark (Prionaceglauca) length composition from the Indonesian Pelagic Longline fishery is presented for 2005 – 2014 period. The total individual was 1,801 fish and the sample length composition was estimated from 1,095 fish (60 - 312 cm FL) caught and reported in the Observer data forms recorded by scientific observers aboard longline fleet since 2005. The results show relatively uniform length distributions, but for the most part of the time series catches were represented by fish > 147 cmFL. Monthly catch at size did not show strong variations where most of them were 190 cmFL (14.6 %) and 200 cmFL (14.7 %). Sex ratio indicated that 61.9 % were Males. The blue shark was caught year-round by Indonesian longline vessels, nominal CPUE (numbers ofBSH/100 hooks) indicated that catches occur in higher latitudinal during the Southeast monsoon (April – September) than Northwest monsoon (October – March).

*igna.prpt@gmail.com ABSTRAK
Penangkapan sumberdaya ikan hiu di Indonesia dilakukan sejak tahun 1970-an dengan menggunakan pancing rawai tuna sebagain by-catch dan pancing hiu sebagai ikan target. Perkembangan kapasitas penangkapan tidak terlepas dari perkembangan motoriasasi perikanan tangkap yang memiki dampak terhadap peningkatan produktivitas penangkapan. Peningkatan pengunaan bahan bakar penggerak mesin yang menghasilkan emisi karbon CO2 menjadi salah satu isu lingkungan selain degradasi sumberdaya hiu. Tulisan ini bertujuan untuk mengestimasi jumlah CO2 yang dihaslkan dari kapal pancing hiu yang di daratkan di PPS Cilacap. Data yang dianaisis adalah data SL3 di PPS Cilacap dari tahun 2012-2016. Hasilnya menunjukkan bahwa kapal pancing hiu rata-rata menggunakan bahan bakar atau Fuel Used Intensity (FUI) 11,6 ton BBM/ton hasil tangkapan. Jumlah CO2 dari penangkapan rawai hiu di estimasi berjumlah 2,7 ton CO2e/ton total tangkapan/tahun. Hasil dari perhitungan ini dapat digunakan sebagai bahan masukan rencana kebijakan penurunan emisi GRK pada sektor pweikanan di Indonesia. Keyword: Jejak karbon, perikanan hiu, Indonesia

*madduppa@yahoo.com ABSTRACT
Sharks and rays are one of the important fishery products that are threatened by excessive fishing and by-catch. Protective activities of shark and ray species are the focus of various stakeholders given the status of some species of sharks and rays that are vulnerable to extinction. Some species of sharks and rays are endangered, listed in Appendix II CITES, and are already fully protected in Indonesia. This study aimed to conduct forensic and population delineation of sharks and rays in Indonesia based on molecular approach. Shark and rays samples were collected across Indonesia with various tissue quality conditions (fresh, dry, bone and dry fins). Detection of species using molecular approach based on mtDNA COI marker. The overall forensic genetic results achieved a detection rate of 99-100%. Species detected, including C. falciformis, S. Lewini, A. pelagicus, Carcharhinus sorrah, and C. amblyrhynchoides. Genetic diversity in Aceh is higher than Tanjung Luar. Some important species were detected in high and significant population structure (C. falciformis: FST = 0.733, S. Lewini: FST = 0.356; M. Alfredi: FST = 0.157; P = 0). In Manta alfredi, highest genetic diversity observed in Komodo Island compared to Nusa Penida and Raja Ampat. Therefore, management activities can be carried out in an integrated manner and based on the characteristics of the location. This method can be used for rapid detection of sharks and rays sold in the market, as well as reveal the area of "hotspots" for each type of shark and ray based on its genetic characteristics.

* WWF-Indonesia *adriandamora@gmail.com ABSTRACT
The category of Silky Shark (Carcharhinus falciformis) in the IUCN Red List of Threatened Species changed from Near Threatened (NT) in 2016 to Vulnerable (VU) in 2017. It indicates that the population of this species has declined and is suspect to be extinct if no immediate conservation action. Periodical monitoring of population parameters and exploitation rate should be an effort to improve the conservation status of this species. The purpose of this study were to estimate growth and mortality parameters and exploitation status of C. falciformis in Indonesian waters. This study was conducted from May 2014 to December 2016 in four landing sites, such as TPI Karangsong Indramayu, PPI Tegalsari Tegal, PPN Brondong Lamongan, dan Muncar Banyuwangi. Samples of C. falciformis were collected by random sampling, but in special case the sensus method applied. The data were analyzed using the analytical model application with ELEFAN I program and Length-converted Catch Curve on FISAT II application. The results showed that the von Bertalanffy's growth parameters: growth rate (K), asymptotic length (L?), and age at L0 (t0) were 0.13 yr-1, 408.02 cm dan -0.19 yr, respectively. The growth curves were Lt = 408.20[1– e–0.13(t+0.19)]. Mortality parameters, i.e. total mortality rate (Z), natural mortality rate (M), and fishing mortality rate (F) were 1.30 yr-1, 0.19 yr-1, and 1.11 yr-1, respectively. Exploitation rate (E) of silky shark was 0.86 yr-1. Improving the quality of data needs to do in order to produce recommendations for better management.

ABSTRACT
A Stock-Production Model Incorporating Covariates (ASPIC) was used to conduct the stock assessment for ray in the Indian Ocean. The stock status became to be pessimistic because of substantial increase in catches in recent years, especially for the catches from Indonesia. The results from most of scenarios indicate the current status of rays in Indian Ocean may be overfishing and overfished (B2016/Bmsy=0.304; F2015/Fmsy=1.45).

*dhika.fishery@gmail.com ABSTRACT
Conservation measure on thresher sharks in Indonesia has been issued through Ministerial Decree no. 57 in 2014 concerning Capture Fisheries Business in Fisheries Management Area of Republic of Indonesia. However, the effectiveness of this regulation is questionable. In fact, the lack of catch and effort data from Indonesian fishery, in general, is still an international concern especially for shark and ray. A method to assess the stock status for data poor fisheries namely Length-based Spawning Potential Ratio (LB-SPR) was developed. This study aims to investigate a possible use of the LB-SPR to estimate spawning potential ratios of thresher sharks using length data from the port-based sampling program (Center for Fisheries Research, WWF Indonesia and WCS Indonesia). Generally, there is a rebuilding trend in the estimated SPR from 2014-2016, indicating that conservation measure has an impact to population. If the SPR40% is adopted as limit SPR, then the estimated values of SPR less than SPR40% suggested that recruitment overfishing might be occurring to pelagic and bigeye thresher sharks (in 2016; 21% and 26% respectively). In fact, the results should be considered as preliminary results, as the size data of thresher shark from port-based sampling program may unrepresentative to population of thresher sharks. Further work is required to gather complete representative of length data of thresher sharks covering all length classes of the fishery.

ABSTRACT
Perairan Probolinggo merupakan salah satu lokasi agregasi musiman hiu paus (Rhincodon typus) di Indonesia sejak beberapa tahun terakhir. Hiu paus di Perairan Probolinggo banyak dijumpai pada bulan Desember sampai Maret, meskipun bisa terlihat sepanjang tahun di sekitar Pantai Utara Pulau Jawa. Hiu paus telah dimasukkan sebagai salah satu spesies yang mendapatkan perlindungan penuh oleh dunia. Penelitian ini bertujuan untuk membangun model pendugaan daerah kemunculan hiu paus di Perairan Pantai Probolinggo. Data kemunculan hiu paus bulan Januari sampai Maret 2016 diperoleh dari Lembaga Whale Shark Indonesia. Parameter oseanografi yang digunakan yaitu suhu permukaan laut (SPL), konsentrasi klorfil-a (chl-a) dan kedalaman, diperoleh dari data penginderaan jauh. Maximum entropy model digunakan untuk memprediksi habitat yang sesuai terhadap distribusi hiu paus dengan didasarkan pada parameter yang berpengaruh terhadap kemunculan hiu paus di Perairan Probolinggo. Nilai area under curve (AUC) sebesar 0,997 menunjukkan bahwa model dapat memprediksi kesesuaian habitat hiu paus dengan sangat baik. Dari ketiga parameter yang diuji, kedalaman (71%) menunjukkan sebagai parameter yang paling berpengaruh terhadap kemunculan hiu paus di Perairan Probolinggo, disusul oleh chl-a (15.7%). Hasil juga menunjukkan hiu paus banyak ditemukan pada kedalaman 10 – 15 meter dan chl-a 0.5-0.7 mg/m3. Distribusi hiu paus yang diperoleh memberi peluang untuk mengidentifikasi spesisfik area dengan tingkat akurasi kehadiran yang tinggi di sepanjang Pantai Probolinggo; pengenalan spesifik area ini bisa dijadikan starting points untuk membangun managemen praktis yang efektif untuk menigkatkan perlindungan hiu paus.

Danish seine and bottom-line are the main fishing gear of shark and ray in PPN Brondong, East Java. Generally the shark and rays catch is the by-catch of the fishing gear. However, the increasing demand for products from both types of fish makes the population of sharks and rays continue to decline. Information on fishing effort and seasons is one source of sustainable fisheries management. The study was conducted in January - December 2012. The type of data used is the monthly production per fish type per fishing gear and the number of monthly trips of each type of fishing gear. Analysis of utilization effort in the form of catch per unit effort (CPUE) while fishing season pattern is average percentage method. The results showed that the average monthly production of sharks was 17.4 tons / month and the highest occurred in March of 27.4 tons, while in the average monthly production sting of 437.6 tons / month and the highest production occurred in April 539.5 tons. The average shark utilization was 0.21 ton / trip, while the rays were 63.8 kg / trip on cantrang and 192.4 kg / trip on bottom-line. The shark catching season occurs in March - August and October, with the peak of the season taking place in March. While on the season arrest season occurs on almost every month except January, with peak season occurs in March and April.

Globally, shark population is declining due to over-fishing and destructive and illegal fishing. One of the shark species that has been caught and traded is Carcharhinus falciformis (Silky shark). This research aims to study genetic structure of C. falciformis in Indonesia, including Aceh, Pelabuhan Ratu, Cilacap, Muncar, Bitung, Ambon, Lombok, north Makasar strait, south Makasar strait, and Timor Sea. Research was conducted by Polymerase Chain Reaction (PCR) using Mitochondrial DNA (mtDNA), control region locus. From 241 total samples, 227 individuals was successfully amplified, and resulted in the fragments of 550 bp long. Analysis indicated that this species exhibits low haplotype (Hd: 0,534) and nucleotide diversity (Pi: 0,00149). Result also showed there is indication of genetic structure on C. falciformis populations in Indonesia (?st = 0.12747; P-value = 0.0000). Genetic comparison of Indonesian and world data of silky shark grouped this species into two different groups, i.e. Indo-Pacific and Atlantic group.

* enitasyenit@gmail.com ABSTRACT
The appearance frequencies of whale sharks in Teluk Cenderawasih National Park (TCNP) is unique because they appear throughout the year and are not related to any seasons. WWF Indonesia's monitoring results from 2011 until now showed the appearance of whale sharks is closely related to the presence of fisherman lift net and anchovies. This study focuses on oceanographic factors in fishing ground areas such as chlorophyll-a and satellite imagery data including chlorophyll-a, Sea surface Temperature (SST) over the last four years resulting in AQUA MODIS level 2 recording with 1km resolution in 2013-2016. The catch of anchovies and chlorophyll-a values showed a fairly good correlation during the west monsoon, 0.305, in addition the relationship between the anchovies with SST has a good correlation value starting in the transition period 1 towards the east monsoon. Based on these data, oceanographic factor conditions in TCNP provide a good opportunity for anchovies that live in warm waters to grow and reproduce. This also influences the appearance of whale sharks closely related to the presence of the anchovies where a positive correlation value is found between the catch of anchovies and whale sharks during the west monsoon and east monsoon in sequence 0,912 and 0.819.

The blue shark (Prionace glauca) is one of the dominant caught and most important bycatch shark species for Indonesian tuna longline fishery in the Indian Ocean. The number of Indonesian tuna longline fleets in Indian Ocean are 1.282 units. There are two types of tuna longline fleet in Indonesia, based on the product destinations, namely fresh and frozen tuna. This working document analyses the catch, effort, nominal and standardized CPUE trends for blue shark captured by this fishery, for the period between 2005-2014. Nominal annual CPUEs were calculated as number (N)/1000 hook. Standardized CPUEs were estimated with Generalized Linear Models (GLMs) using year, quarter, area, and operational characteristics of the gear. Model goodness-of-fit and model comparison was carried out with the Akaike Information Criteria (AIC) and the pseudo coefficient of determination (R2) and model validation with a residual analysis. The final estimated indexes of abundance were calculated by least square means (LSMeans). Preliminary results showed the factors that contributed most for the deviance were the area, followed by year, quarter, number of hooks between floats (NHBF), and then the other effects and the interactions. The trends of the standardized CPUEs were relatively similar to the nominal series, but with smoother peaks. In general there were no noticeable trends, with the series varying along the period.

Tirtadanu*, Suprapto, Suwarso * Balai Riset Perikanan Laut * tirtadanu91@gmail.com ABSTRACT
Rays fishing in Java Sea has produced high yields and gave the economical contribution for fisherman in the Java Sea. Information about stock density and biomass were important information for knowing the potential yields in the Java Sea that could be fished for its sustainability. Aims of this research were to study the composition, distribution, stock density and biomass of rays in Java Sea. The research was conducted on October – November 2017 by trawl exploration using Research vessel Bawal Putih 03 in 30 stations of Java Sea. The estimation of stock density was analyzed by swept area method. The dominant rays that were caught in Java Sea were Himantura gerrardi (52.7%), Dasyatis kuhlii (22.2%) and Himantura
uarnak (18.9%). The catch rate of rays ranged 0-95 kg/hour and the mean catch rate was 8.4 kg/hour.
The highest catch rate based on spatial distribution (95.32 kg/hour) was at the northern waters of Banten and the highest mean catch rate based on the depths (12.5 kg/hour) was in the depth of less than 30 m. The estimation of stock density in Java Sea was 149.6 kg/km2 and the biomass of rays was 69.665 ton. Keyword: Biomass, Himantura gerrardi, stock density, rays, Java Sea

* agusarifinsentosa7@gmail.com ABSTRACT
The artisanal fishermen based in Tanjung Luar have been sharks as main target species in their fishing, but sometimes others aquatic species have been caught deliberately as baits or unintentionally as by-catch. This study was done to describe ecologically related species (ERS) found in sharks fisheries by Tanjung Luar fishermen. Data were taken based on interviews and enumerator record for sharks catch in Tanjung Luar during January to November 2016. The result indicated that ERS consisted of fish species with lower trophic levels than sharks. About 80.60% of ERS were fishes associated with a demersal marine habitat, and about 69.44 %% ERS demersal were associated with coral reef habitats. While only about 19.40% of ERS were pelagic and commonly caught by surface fishing gear e.g. longlines and drift gillnets Keyword: Ecologically related species, sharks, fishing, Tanjung Luar

ABSTRACT
Mobulids ray are large filter-feeders that require high-density prey to meet their energetic requirements. However, the oligotrophic environments are the major challenges for mobulids ray, where the prey availability is highly fluctuated and poorly-distributed. Understanding the foraging strategies (e.g. when, where, and how the trophic interaction happened) is a fundamentally important aspect in studying the ecology of these animals. Using the generalized adaptive model, this study try to examine the ecological interaction between oceanographic and temporal covariates with biological aspect data (i.e. disc-width) of Mobula birostris (n = 70), Mobula japanica (n = 70), and Mobula tarapacana (n = 33) which landed in Lamakera. Our GAM model explains 90.7% the DW variability on Mobula birostris and strongly influenced by chlorophyll-a (55%; >4-8 mg.m-3) which peaking during July-August (DW; 170-660 cm; ±SD= 366.66±258.90 cm). Mobula japanica was explained 55.4% with the strongest predictor from Julian day (27.19%) and peaking during June-August (120-260 cm; 167.33±39.00 cm), followed by chlorophyll-a concentration (17.22%; >3 mg.m-3), and waters temperature (10.98%; >29.5oC). Furthermore, the highest GAM model explains is Mobula tarapacana (94.9%) where the chlorophyll-a concentration is the strongest predictor (57.77%; 1-2 mg. m-3), followed by waters temperature (33.30%; 26-29oC), and not showing significant effects from Julian day. Eventually, the variability of DW on Mobula
birostris and Mobula japanica was triggered by seasonal upwelling which provide high-density prey for
various body sizes. While, on Mobula tarapacana not showing significant differences along the season, where the variability more influenced by local oceanographic in the region.

ABSTRACT
Arafura is a fertile Indonesian waters because its waters are getting a lot of flow from rivers that carry nutrients. Abundant resources cause many fishing activities that will lead to changes in resource stocks including stingrays. The research was conducted by using Baruna Jaya IV Research Vessel with swept area motion. The purpose of this research is to know the composition of species and distribution of abundance of fish including pari in Arafura waters. The stingrays in these waters consist of 5 families: Dasyatidae (84.83%), Urolophidae (6.81%), Gymnuridae (5.26%), Rhinobatidae (1.86%) and Myliobatidae (1.24%). This fish is dominantly caught in the waters around Agats and Kota Mappi. Dasyatis annotata female range from 14.0-26.0 cmWD and male ranged between 15.0-23.5 cmWD, Himantura jenkinsii ranged between 20.0-58.0 cmWD (female) and 22.0-26,0 cmWD (male). Distribution size of Himantura undulata female ranged between 88.0-122.0 cmWD and males ranging 88.0-109.0 cmWD while the Taeniura
lymma fish was between 17.5-82.0 cmWD (female) and between 15.0-25, 0 cmWD (male). The
distribution of female Gymnura australis ranges from 17.0-72.0 cmWD and male fish between 26.0-51.0 cmWD and the stingray size of Urolpus sp. females ranged from 19.0-130.0 cmWD and male fish ranged between 21.0-118.0 cmWD. Sex ratio male and female is balanced for Himantura undulata and Urolopus sp. while the other types are not balanced.
