The blood cockle refugia site was established in Prey Nop 2, Sihanouk, Cambodia in 2006 to ensure the future stock of the resources. This study aimed to evaluate the effectiveness of the blood cockle refugia site considering fishery and population dynamics perspectives. The respondents of this study were all females (n = 25) who collect blood cockle as a supplementary source of income. The collection method inside the refugia site is restricted only to hand collection. For the population dynamics, the blood cockle samples inside the refugia site exhibited a positive allometric growth pattern and a higher Pauly’s condition factor (K) than those from other sampling sites. A greater percentage of the blood cockle larger than the size at first maturity inside the refugia site was strong evidence of the effectiveness of the refugia site and can be used as a scientific reference for the development of more effective management measures. 2025-05-01T00:00:00Z http://hdl.handle.net/20.500.12066/7616 Fish for the People Vol.23 No.1 This first issue of Fish for the People in 2025 features the key achievements of the Japanese Trust Fund (JTF) 6-2 projects implemented by SEAFDEC from 2020 to 2024, which are categorized into three pillars, namely: Pillar I. Strengthening the promotion of sustainable fisheries in Southeast Asia; Pillar II. Promotion of sustainable aquaculture and resources enhancement in Southeast Asia, and Pillar III. Promotion of sustainable development of inland fisheries in Southeast Asia. Under the project “Responsible Fishing Technology and Practices,” a study was conducted in the Gulf of Thailand using M.V. Plalung to confirm the benefits of V-shaped otter boards during trawl fishing operations to assess catch quantity, fuel efficiency, and CO2 emissions. The study implied that V-shaped otter boards offer the potential for high yields and efficiency; however, careful application is required to balance environmental impacts and operational costs. Gender equality in inland fisheries was promoted across Southeast Asia under the projects “Management Scheme of Inland Fisheries in the Southeast Asian Region” and “Sustainable Management of Anguillid Eel Fisheries in Southeast Asian Region.” The two Projects promoted inclusive and equitable inland fisheries policies by engaging women in fisheries-related decision-making and management, involving women in practical tasks such as water quality monitoring and resource management, and providing training to ensure that women have the skills and knowledge to contribute to sustainable inland fisheries management. In Cambodia, blood cockle (Tegillarca granosa) is a vital food source and income for coastal communities.

The V-shaped otter boards were designed by the SEAFDEC Training Department in 2018 to improve fuel efficiency, reduce seabed disturbance, and enhance operational safety. The initial sea trials, comparing only the main engine revolution, indicated a 5.4 % reduction in fuel consumption, attributed to a decrease in engine revolutions while maintaining the same trawling ship speed. Between 2020 and 2023, further experiments were conducted as part of the project “Responsible Fishing Technology and Practices” supported by the Japanese Trust Fund (JTF) 6-2. The experiments were conducted to confirm the benefits of V-shaped otter boards during trawl fishing operations, including improved energy savings and reduced environmental impact. The study involved 14 trawl fishing operations in December 2023 in the Gulf of Thailand using V-shaped otter boards on the M.V. Plalung. Collapsible crab traps and gillnets were also operated during each trawl fishing operation to compare catch quantity, fuel efficiency, and CO₂ emissions. The results implied that trawl fishing operations with V-shaped otter boards demonstrated significant improvements in catch per unit effort (CPUE) and fuel efficiency over time. However, a negative correlation was observed between trawling duration and catch quantity, suggesting that extended trawling does not necessarily increase catches. Additionally, a positive correlation between trawling duration and fuel consumption was identified, highlighting the adverse environmental impact associated with prolonged fishing operations. The study concludes that while V-shaped otter boards offer the potential for high yields and efficiency; however, careful application is required to balance environmental impacts and operational costs. Future research should include controlled experiments comparing the V-shaped otter boards with traditional designs under identical conditions to validate its effectiveness. Further analysis of hydrodynamic and seabed impacts is recommended to explore the potential advantages of V-shaped otter boards in reducing drag and minimizing environmental disturbance. 2025-06-01T00:00:00Z http://hdl.handle.net/20.500.12066/7614 Fostering Women’s Contributions to Inland Fisheries in Southeast Asia Muthmainnah, Dina; Suryati, Ni Komang; Supriyadi, Freddy; Soesmono, Andi; Shimoda, Toru; Nurwanti Gender is defined by the concept of duties, functions, and roles attributed to women and men in the public and private lives of society. In the context of gender policies, the Inland Fishery Resources Development and Management Department of the Southeast Asian Fisheries Development Center (SEAFDEC/IFRDMD) has actively promoted gender equality in Indonesia, Cambodia, Lao PDR, and Philippines since 2020. Women have taken leading roles in the inland fisheries value chain, particularly in processing and marketing. However, women have often been limited in their participation in decision-making processes. Recognizing these challenges, IFRDMD was committed to promoting gender equality in inland fisheries in Southeast Asia under the projects supported by the Japanese Trust Fund 6-2, entitled “Management Scheme of Inland Fisheries in Southeast Asian Region” and “Sustainable Management of Anguillid Eel Fisheries in Southeast Asian Region” which were implemented in 2020–2024. 2025-06-01T00:00:00Z
