Reducing the impacts of fishing activities through the application of improved fisheries technology Thanasansakorn, Suthipong; Thimkrap, Thaweesak Fishing is an essential source of employment and protein for coastal communities. However, irresponsible fishing practices, such as the discard of unwanted catches, carbon emissions, destruction of seabed, and overfishing, may create negative impacts on fishery resources and the environment if not properly regulated. The impacts can be mitigated by promoting responsible fishing by using selective fishing gear. Moreover, the design of fishery vessels could be improved to enhance energy efficiency and safety at sea to alleviate living conditions and hygiene of the fishing crew onboard. In addition, the improvement of appropriate fishery machinery, tools, and refrigeration system is envisaged to optimize the required workforce of the fishery vessels, while maintaining the quality of the catch prior to landing. In this regard, the project “Responsible Fishing Technology and Practices” supported by the Japanese Trust Fund is implemented by SEAFDEC Training Department (TD) from 2020 to 2024. The objectives of the Project are to: 1) promote responsible fishing technology and practices to mitigate fishing impacts on the marine ecosystem, 2) promote marine engineering technologies and their applicability in enhancing the capability of fuel consumption efficiency and safety in fishing operations, and 3) enhance human resource capacities on fish handling techniques onboard fishing vessels. It is envisaged that through the Project, the fishing and marine engineering technologies at the national and regional levels will be improved as well as human resource capacities in the Southeast Asian region are enhanced. Furthermore, the activities undertaken by TD through this Project are also in line with the Resolution on Sustainable Fisheries for Food Security for the ASEAN Region Towards 2030 stipulating the need for the ASEAN Member States (AMSs) to undertake relevant actions, i.e.: RES 7: Promote sound management of fishing capacity and use of responsible fishing technologies and practices, recognizing increasing emphasis on rightsbased fisheries; and at the same time, secure the rights and well-being of inland and coastal fisheries communities as well as the ecological well-being; RES 9: Support the efforts to promote low carbon development technologies by minimizing the contribution of the fisheries sector to greenhouse gas emissions, with emphasis on promoting the use of energy-efficient equipment and alternative energy sources; and RES 21: Optimize the utilization of catch/harvest by reducing post-harvest losses and wastes to increase fish supply and improve economic returns through promotion of appropriate technologies, facilities and best practices along the supply chain.

Achieving high production of micropropagated seaweed through optimization of the culture protocol Sollesta-Pitogo, Hananiah; Faisan, Joseph Jr.; de la Cruz-Aranas, Joesyl Marie Kappaphycus and Eucheuma are the two carrageenanproducing red algae extensively cultured and farmed in tropical and subtropical waters. Seaweed production accounted for 5.4 percent of the world’s aquaculture production in 2019, which was over USD 15 billion in value. With this value share, the production of seaweed farming was higher than other aquatic commodities, such as tilapia, carp, shrimps, and others (Cai et al., 2021). The red algae production of the Philippines started in the 1960s (Ronquillo & Gabral-Llana, 1989), and by the early 2000s, the country had become the world’s top supplier of seaweed, particularly Kappaphycus sp., until 2007, when Indonesia outperformed it. Problems and challenges in seaweed farming, including climate change, pests and diseases, and biosecurity issues, caused the continuous decline of the seaweed production yield (Faisan, Sollesta-Pitogo, & de la Peña, 2022). Furthermore, the deterioration of seaweed quality caused by the repetitive use of vegetative cutting methods has also become one of the most pressing concerns in seaweed farming. Unfortunately, this procedure of growing plantlets for farming is one of the most common methods many seaweed farms used in the Philippines and other countries. Research in SEAFDEC Aquaculture Department (AQD) looks into breaking from the conventional method of farming seaweed plantlets and optimizing laboratorybased production. With this, it hopes to create a more sustainable source of propagules, better growth and survival in grow-out, and a higher carrageenan quality in cultured Kappaphycus alvarezii.

Development of artificial reefs in Southeast Asia: Malaysia in focus Ayob, Muhammad Amirullah Al Amin; Ali, Mazalina; Yusof, Hamizah Nadia Alias@; Arshad, Abd Haris Hilmi Ahmad The development of artificial reefs (ARs) in Southeast Asia reflects a range of motivations and approaches, from fisheries management to coastal protection and coral reef restoration. Such development is in line with the Plan of Action on Sustainable Fisheries for Food Security for the ASEAN Region Towards 2030, specifically “Plan of Action No. 35. Promote resource enhancement approaches with appropriate monitoring and evaluation programs, e.g. deployment of appropriate resource enhancement structures, restocking of commercially-important aquatic species, and restoration of degraded habitats, taking into consideration possible socio-ecological impacts.” While not without challenges, ARs have demonstrated their potential as a tool for marine conservation and sustainable development in the region. Since 2006, the Marine Fishery Resources Development and Management Department (MFRDMD) of SEAFDEC, in collaboration with the Department of Fisheries of Malaysia (DOFM), has been actively engaged in a research and development program on ARs. Over the years, the long-term research activities yielded valuable oceanographic information for the advancement of AR design and construction techniques, which have been effectively utilized in the Malaysia Artificial Reefs National Program since 2006. Besides, research findings were crucial for the DOFM to innovate and implement new technologies, leading to continuous improvements in the effectiveness of the ARs program. This has significantly enhanced marine habitats and fishery resources across Malaysia. Furthermore, the information obtained was also shared by MFRDMD during the conduct of several initiatives and activities in the region including the conduct of a series of regional workshops on ARs since 2004, publication of “A Guide to Make and Set Durable Artificial Reef Fish Aggregating Devices (ARFADs) for Coastal Waters” in 2004, and publication of research paper “Protecting Coastal Habitats and Enhancing Fisheries Resources Using Big Size Artificial Reefs in the East Coast of Peninsular Malaysia” in 2013.
