Moving Towards the ASEAN Fisheries Policy
Oceanic and neritic tuna are abundant and commonly found in waters throughout Southeast Asia. While oceanic tunas migrate across oceans and seas, neritic tunas mostly inhabit the economic zones and sub-regional marine waters of Southeast Asia. Therefore, the status and uncertainties regarding the distribution, migration and utilization of neritic tuna stocks in Southeast Asian waters and subregions need to be addressed before appropriate national and subregional tuna management measures and plans are developed.
Sustainable Management of Neritic Tunas in Southeast Asia
All tuna resources are economically important in Southeast Asia, generating export revenue for the countries and providing important protein sources for domestic consumption. While the catch of oceanic tuna is reported to have decreased, the catch of the neritic tuna species continues to increase, making these species more important and increasingly the target of exploitation by commercial and local fisheries, especially now that attractive prices offered by processors for such species.
Neritic Tuna Fisheries of Southeast Asia
However, seine nets are still an important gear for some Southeast Asian countries such as Indonesia and Vietnam, where 37% of the country's total production of neritic tuna at 72,650 metric tons is caught using seines (Thong, 2013).
Issues, Challenges and Regional Plan of Action
Actions taken by SEAFDEC and the AMSs
Stock Assessment of Neritic Tunas
Results of stock assessment of longtail tuna in the Indian Ocean side of Southeast Asia using Kobe plot. Results of stock assessment of kawakawa in the Pacific side of Southeast Asia using Kobe plot. Results of stock assessment of kawakawa in the Indian Ocean side of Southeast Asia using Kobe plot.
Risk Assessment of the Neritic Tuna Stocks
In addition, the results of the Indian Ocean-side neritic tuna stock assessment in Southeast Asian waters are similar to those determined by the IOTC for the entire Indian Ocean (IOTC, 2015; IOTC-WPNT06-2015-21). . Probabilities (%) of violation of TBmsy and Fmsy in 3 years (2017) and 10 years (2024): longtail tuna on the Indian Ocean side in Southeast Asian waters. Probabilities (%) of violation of TBmsy and Fmsy in 3 years (2016) and 10 years (2023): longtail tuna, Pacific side in Southeast Asian waters.
Way Forward
WP05 and WP06 presented at the Third Meeting of the Scientific Working Group on Neritic Tunas Stock Assessment in Southeast Asian Waters, 27-29 June 2016, Chonburi, Thailand. Paper presented at the Consultative Meeting on Regional Cooperation Sustainable NeriticTuna Fisheries in Southeast Asian Waters, 8-10 October 2013, Songkhla Province, Thailand. The technical information and related materials produced by SEAFDEC are specifically intended to promote sustainable fisheries management in the Southeast Asian region.
Striking a chord: the historical circumstances
In addition, SEAFDEC was able to promote confidence in the dissemination of fisheries information through regional cooperation, as SEAFIS served as the Southeast Asia regional input center for FAO's Aquatic Services and Fisheries Information System (ASFIS). The MFRDMD also continued the MFRD's previous tasks of collecting and publishing fishing effort statistics for the South China Sea area since 1994, which had been taken over by TD, as in the interim. Fishery Statistics Bulletin since 1996, and later the said data were included in the Fishery Statistics Bulletin for the South China Sea area.
Plight of SEAFDEC Information Programs
Recognizing the need to promote the image of SEAFDEC as a unified organization, in 1994 the SEAFDEC Council asked SEAFDEC to develop an information personnel exchange program involving relevant personnel from the departments that would aim to improve information networks in the Southeast Asian region. . This paved the way for the implementation of the SEAFDEC Information Staff Exchange Program (ISEP) which was launched in 1995, later renamed the SEAFDEC Information Staff Program (ISP). Guided by the SEAFDEC Information and Communication Policies, various information materials and services were developed and/or improved by the SEAFDEC Secretariat as coordinator of the Programme, in collaboration with the SEAFDEC Technical Departments.
Paradigm shift in information dissemination
As a means of formalizing the establishment of the Department's warehouses, the SEAFDEC Secretariat organized. Through a centralized repository hosted by the SEAFDEC Secretariat, users will be able to access all SEAFDEC publications (of all Departments), as the system allows the institutional repositories of the SEAFDEC Secretariat to automatically collect materials available in the institutional repositories of departments (minimizing the redundancy of files in both Departments and the Secretariat). The SEAFDEC Secretariat and Departments would develop and/or improve their respective institutional repositories as these would increase public access to publications produced by SEAFDEC, particularly through the search engine, and increase SEAFDEC's visibility to the public.
About the Authors
Specifically, the improvement of the visibility of SEAFDEC will be further made by SEAFDEC secretariat and departments through the use of video channels, e.g. Economic development program has been implemented in Indonesia since 1969 but little has been done to develop its capture fisheries in inland open waters, e.g. Considering that the inland waters are the main source of income for the rural people, there is a need to manage the country's inland open water capture fisheries for sustainability.
Sustainable Management of Inland Capture Fisheries for Food Security: Experience of Indonesia
Efforts to achieve sustainable capture fisheries in inland open waters are generally not based on scientific information leading to less developed technologies on inland capture fisheries, despite the country's long history of capture fisheries in inland open waters spanning centuries. corridor is (Sarnita, 1987). Nevertheless, certain alternatives have been promoted in Indonesia to manage the country's inland water fisheries, and these are through replenishment and restocking of inland waters with cultured fish species, and the establishment of fish reserves in inland waters.
Open Water Fisheries
Contribution of Open Water Fisheries to National Economy of Indonesia
Status of Inland Capture Fisheries in Indonesia
Its fishing season takes place when the water level is low or during the dry months (August-September). Fishing season of mpangg and selambau is at the end of the wet months (April-June), which block and obstruct the fish migrating from lebak or flood areas to rivers or lakes. Mangumpe and beje are usually operated in the dry months (July-September) when only the deeper water bodies (river, lake and lebung) have water.
Catch Composition by Fishing Gears
For example in Village Alow-Alow which is near the mouth of the Barito River, where in the dry season the salinity is 8.5 ppt, the catch can be 0.5 kg/. In Pulau Kembang village near Banjarmasin city, in the dry season (salinity = 3.0 ppt), the catch can be 1.0 kg/person/day (5-7 hooks and lines).
Production from Inland Fisheries
Pollution caused by industrial and domestic waste is another problem, as illustrated in the case of the water quality of the Solo River. These vegetations maintain the function of swamp forests as habitat, food and nursery. The results of a case study in the Solo River in Java showed that industrial and domestic wastes have caused severe water pollution.
The socio-economic condition of inland fisheries in Indonesia
Based on monitoring and interviewing fishermen with more than 5 years of fishing experience, the production trend has been decreasing every year by 10 to 15% due to increased fishing activities and destruction of the ecosystem. Sedimentation in open waters has been occurring for years due to the high exploitation of forests, the continued adoption of shifting agriculture and to a certain extent, the establishment of recreational resorts in mountainous areas. Fishing activity in open waters is difficult to control, while illegal fishing activities (eg electrofishing, use of poison) are still rampant, despite the passage of the Fisheries Law No. 9 of 1985 .
Environmental Conditions in Fishing Areas
The results of the case studies conducted on the Kapuas, Musi and Barito rivers showed that the middle reaches of these rivers have many floodplains and swamp forests that have potential for increased fish production. Important swamp forest vegetation consists of putat (Barringtonia acutangula), mentangis (Oxora mentangis), menyawai (Elacocarpus submonoceras) and melayak (Croton spp). The distribution of open water fishermen in Indonesia is shown in Table 3, which is likely not according to open water areas, but based on the population on an island.
Inland Fisheries Management System
The total fish harvested from the inland fishery may not be significantly high (tonnes/year), but the inland capture fishery's production annually contributes approx. tonnes/year to the country's total production from inland capture fisheries.
Conclusion
Shahadat Hossain
Over the years, it has been noted that the construction of barrages and dams without fish passage on several rivers had reduced the river reach of the hilsa (Jafri, 1988). Although fishways or fish passes had been constructed in the barrage across the Cauvery River at Coleroon (Wilson, 1909) and at the Mahanadi River at Cuttack (Southwell and Prashad, 1918), but it was observed that such facilities were not have managed to function. supporting Hilsa's migration. As a result, hilsa had spread across the wider areas of the northern part of the Bay of Bengal, causing the significant increase in marine catches of hilsa in Bangladesh, Myanmar and India since the 1990s (FAO, 2015; DoF, 2014; Hossain et al., 2014).
Historical Production of Hilsa in Bangladesh
In this regard, it would be worthwhile to initiate a data prospecting and data retrieval effort for the catch composition of hilsa since 1950s in the Bay of Bengal. A review of the biology and fisheries of Hilsa ilisha in the upper Bay of Bengal. A note on the occurrence of spawning of Hilsa ilisha (Hamilton) in the river Brahmaputra (Assam).
