Marine capture fisheries of Thailand had been in the top ten fisheries production countries in the world. Indo Pacific mackerel (Rastrelliger brachysoma) is one of the country's most important pelagic species, particularly those caught from the Gulf of Thailand. However, increasing demand of the Thai people together with the rapid development and improvement of fishing gear and fishing techniques resulted in the stock reduction of the Indo Pacific mackerel and some other commercially important pelagic species in the Gulf of Thailand. Therefore, the Department of Fisheries of Thailand established fisheries refugia or closed seasons and areas in some parts of the Gulf of Thailand in order to prohibit some fishing gear and fishing techniques as well as monitor the changes in the status of aquatic species and also the fishing methods in order to determine appropriate measures from time to time for sustainable use of these pelagic species. During the past 60 years (1953-2015), the Department of Fisheries issued a total of 13 fisheries management measures in five periods relating to the development of fishing gears and fishing techniques corresponding to the 'Gulf Closing' in the southern areas (Prachaup Khiri Khan, Chumphon, and Surat Thani) with the aim of conserving the spawning areas and nursery stage of aquatic resources in the Gulf. The measures for conserving the Indo-Pacific mackerel were used as basis for the formulation and development of other conservation measures. Cancellation and revision of these measures were also made from time to time in accordance with the change of status of the fishery resources and the effective management of the aquatic resources for sustainable exploitation.

The process of identifying and establishing fisheries refugia is discussed in this paper, where 'fisheries refugia' is an approach that integrates fisheries and habitat management to improve fisheries management in terms of space and time for sustainable use of fish stocks and protection of habitats. Also presented in this paper are site specific studies that showed the source and sink of fish eggs and larvae used in identifying the spawning and nursery refugia. Success of fisheries refugia depends on the actions at the local level where the level of community support depends on the involvement of local stakeholders in actions. Harnessing local knowledge is critical for good site selection and establishment of management measures. Science based management measure is most acceptable while education, information and communication is very helpful in terms of community acceptance of the fisheries refugia approaches. Other resource enhancement and management described in the paper are the closed fishing season for sardines in Zamboanga Peninsula, and closed fishing season for small pelagic fishes in the Visayan Sea and Davao Gulf. The effects of these management measures are seen in increased number of fish species as well as fish production.

The Department of Fisheries Malaysia (DOFM) has taken initial steps in ensuring that natural resources are not threatened with extinction by introducing the concept of special refugia for two commodities, such as the penaeid shrimp and lobster. Tanjung Leman in Johor (Southeast of Peninsula Malaysia) has been identified as special refugia for lobster, and Kuala Baram (Northeast of Sarawak State) as special refugia for the penaeid shrimp. Since 2006, annual landings of lobster (Panulirus spp.) in Johor had been dramatically decreasing below 500 metric tons (MT) from previously recorded which was 2059 MT in 2002. Landings of lobster had dropped particularly in the West Coast of Peninsula Malaysia while landings in the East Coast, such as in Sabah and Sarawak also showed decreasing trend to below 200 MT. For penaeid shrimp (Penaeus monodon), capture data mainly from Sabah and Sarawak also showed decreasing pattern from 1948 MT in 2003 to 1226 MT in 2013. The month of March is the highest peak for annual landings of lobster and penaeid shrimp in Malaysia, mostly delivered by trawlers. Harvest of lobster and penaeid shrimp had contributed around 89% and 74%, respectively, to the overall catch landings of the country. Currently, several committees and action groups involving various stakeholders in the two areas were established and plans of action for 2014-2018 serve as written guidelines and references for all stakeholders. The successful implementation of the concept of refugia for seasonal conservation of a freshwater fish in Sabah under the program called Tagal System, had been an inspiration of the concerned stakeholders, believing that such success could be replicated in other areas of the country and for other economically-important aquatic species.

Blood cockle is one of the major marine products in the community but the resource is encountering the risk of stocks degradation mainly due to destruction of the fisheries habitats from rampant illegal fishing by dredgers and over-exploitation. Considering this as a very critical issue, the Fisheries Administration of Cambodia and Community Fisheries Prey Nub 2 in collaboration with SEAFDEC agreed and established the Blood Cockle Refugia. Since the project supported by SEAFDEC ended in 2009, a research was conducted in 2014 to evaluate the effectiveness of the blood cockle refugia. The specific objectives of the study were to evaluate the current status of the refugia management and improve the blood cockle resources in the Community Fisheries. The study used quantitative approach to collect data including key informant interviews with key stakeholders such as fishers, fisheries officers and commune councils, focus group discussion and field observation. Documents from the Integrated Coastal Resources Management Project: Sihanoukville, were reviewed. The report findings indicated that blood cockle refugia is still working under the guidance of the Provincial Fisheries Administration which modified the management approach. The regulation established on blood cockle size to be harvested was no longer enforced because local fishers complained about its negative impact on their daily catch. Other concerns of the Provincial Fisheries Administration included the relatively big proposed site for refugia which was difficult to manage; members of the Community Fisheries seemed not to be actively participating in the management scheme although the concerned local fisheries officers were working hard to implement the said scheme. Nevertheless, the daily catch of blood cockle was significantly stable indicating the effectiveness of the refugia. In general, the blood cockle refugia in Community Fisheries Prey Nub 2 brought a significant impact not only on blood cockle harvest but also on the habitats that this species rely on such as mangroves and sea grass beds that had been well protected. Anyhow, the management approaches of the refugia should be revised to reflect the socio-economic and environmental conditions of the local people in the area. Few suggested recommendations should be taken into account, such as (1) the restriction on size of blood cockle to be harvested should be modified, (2) the coverage area should be reduced, (3) the current Blood Cockle Team of the Community Fisheries should be restructured, and (4) a scientific research on blood cockle biology should be conducted using the baseline data from ICRM-SHV supported by SEAFDEC.
