Most of the fisheries in the Southeast Asia region have declined, especially over the past 30 years. This led to the establishment of the EAFM Core Team to facilitate the development of the Fisheries Management Plan.

However, most of the commercially important fishery resources in the region's coastal waters have declined due to a number of factors including overfishing, illegal fishing, destructive fishing practices and environmental degradation. Following the adoption of the 2001 Resolution (RES) and Plan of Action (POA) on Sustainable Fisheries for Food Security in the New Millennium (SEAFDEC, 2001) and in particular considering the need to: “Efforts to conserve and restore aquatic habitats that are essential to increase fishing resources" (RES#9), and to "optimize the use of coastal waters through resource enhancement programs such as encouraging the placement of artificial reefs and structures, promoting coordinated and effective planning for coastal fisheries management programs, ..." (POA#4 ) SEAFDEC has undertaken several programs and projects aimed at addressing overfishing and environmental degradation in Southeast Asian waters, which include programs to improve coastal fisheries resources by developing strategies to modify coastal habitats. restore and increase their productivity (Ebbers, 2003).
From artificial reefs to fish enhancing devices
Fish aggregation devices, such as artificial reefs, have been established as an important tool for developing fishing ground and increasing fish production from coastal areas, but the cost of installing such devices is significantly high, especially in terms of investment, and has necessitated that the management of such installations should be the responsibility of government agencies.

Benchmarking the Adoption of Fish Enhancing Devices in Southeast Asian Waters: the coastal waters of Thailand in focus
The anchor line connects the floats to a heavy cast concrete anchor on the seabed. Although the use of FEDs still involves the deployment of FADs on fishing grounds, fishing is regulated, if not completely prohibited, especially in the area of the FADs.
Benchmarking the use of FADs in Thailand
Results and Discussion
As a result, the use of FEDs of various designs has widely spread to Thailand's coastal provinces. In summary, different characteristics of FEDs in terms of structure, design and installation were observed during the survey along the coastal areas of Thailand. From the survey, it was also observed that anchored FEDs were mainly found in 14 provinces (29 fishing groups) in the Gulf of Thailand and the Andaman Sea.
Furthermore, in Trat province, fishermen modified the design of FEDs to make them more suitable in the area taking into account the depth of sea water.

Upgrading the Purse Seine Fishing Vessels to Promote Responsible Fishing Operations
The funds provided by JTF to cover the cost of the necessary equipment and fish conservation systems in fishing vessels enabled SEAFDEC/TD to pilot test the technology on the implementation of a hydraulic ring signal retrieval device (power block) in the Pattani province, Thailand (Figure 1). In order to facilitate the pilot testing, SEAFDEC entered into a cooperative agreement with the Department of Fisheries (DOF) of Thailand, the Fisheries Association of Pattani Province, and the operator of the pilot fishing vessel, Nor Larpprasert 8, for a period of three. year starting in July 2018.
Pilot-testing of the improved technology in purse seines
Trend of fisheries production of Thailand
Thailand is therefore making efforts to address the issues and concerns encountered in its fisheries sector so that production of fish and fishery products, as well as trade in fish and fishery products, can be sustained for the economic development of the country and food security of its people . One such effort is to ensure that the country's marine capture fisheries are developed sustainably, through improvements in fishing gear and fishing machinery by adopting appropriate technology for optimizing energy efficiency (saving on fuel) and reducing of labor on board fishing fleets, especially in ring signal boats. .
Effects of the improved technology on purse seiners
Thaweesak Thimkrap is an engineer attached to the Fisheries and Postharvest Engineering Division of the Training and Research Supporting Division of the SEAFDEC Training Department in Samutprakan, Thailand. After the RSW cooling system was installed on board the pilot fishing vessel, the quality of the fish landed improved. It should be noted that before the installation of the RSW cooling system, the pilot vessel used to consume 300 boxes of ice, but after such installation, the amount of ice used corresponded to only 150 boxes.

After the hydraulic crane and hydraulic power block were installed, the pilot seine vessel has reduced the number of crew members by 40%, i.e. once the improved technology is refined and verified, this can be promoted to the Southeast Asian region to improve sustainable fisheries development in the region.
Before such promotion, however, further studies must be carried out on the operations and management of ring signal boats (Box 2).
Boosting the Traceability of ASEAN Fish and Fishery Products through the eACDS
In response to the request of the AMSs, SEAFDEC initiated capacity building activities to enable the AMSs to comply with the requirements of the EC Regulation (Siriraksophon et al., 2016), while the AMSs also amended their laws and administrative regulations to meet the requirements laid down in the EC regulation.

Structure and Processes Involved in the eACDS
The Fisheries Port Authority issues the initial CD with a password to access the mobile application for catch reporting at sea. In the markets, consumers will be able to trace the origin of the fish catch and other information from the QR code linked to the MD.

Towards Reviving the Production of Philippine Native Aquatic Species
Declining catch of native fishes in major lakes of the Philippines
Another threat to the production of native fish species is the introduction of invasive alien species such as the predatory fish Chitala ornata or the knife fish (Figure 5). Naturally distributed in Cambodia, Lao PDR, Thailand and Vietnam, this ornamental fish is believed to have been accidentally introduced into Laguna de Bay during Typhoon Ondoy in 2009 (Guerrero III, 2014). Recently, a report on the feeding ecology of the knifefish in Laguna de Bay found that silver therapon as the most important component of its diet (Corpuz, 2018), resulting in a significant decline in the silverfish population. wild therapon in the lake.
This problem has resulted in fishermen earning less income than before, when most of their catch was farmed bigeye carp (Aristichthys nobilis), milkfish (Chanos chanos) and tilapia (Oreochromis niloticus), which command higher market prices and are more popular mild as a knife fish.
Government initiatives on habitat conservation and restoration of native
Intensifying research programs on native freshwater fishes
Information has been reported on the larval biology of silver therapy, particularly in feeding characteristics (Aya et al., 2015a, b), early life history (Aya & Garcia, 2016), larval and early juvenile development (Aya et al., 2017), and the effect of physical substrate, including prey selection and feeding cycle for this species (Aya et al., 2019). In addition, a preliminary study of weaning and larval food suitable for rearing silver therapon larvae has been carried out (Aya et al., 2015c). The results of feeding biology and larval development studies of silver therapy are the key source of valid information to develop a viable hatchery seed production technology for this valuable food fish.
The development of hatchery diets to improve reproductive performance and egg and larval quality from silver therapy is still ongoing.
