Using yield per recruit analysis to determine fish stock status Pattarapongpan, Supapong During the past decade, the fishing industry in Southeast Asia had been confronted with concerns on declining fishery resources due to overfishing, and more particularly because of the continued practice of illegal, unreported, and unregulated (IUU fishing) as well as degradation of the habitats that bring about negative impacts to the economic, social and ecological attributes of fisheries affecting food security. It has therefore become necessary that management measures should be established for the sustainable management of the fishery resources in general. However, attempts to establish such fisheries management measures have encountered problems on inadequacy of data for stock assessment that hinder the efforts to develop such measures. During discussions on the sustainable utilization and management of fishery resources in the Southeast Asian region, the need to improve data collection had always been raised on various occasions for the development of appropriate management measures of the fishery resources. Many studies have indicated that the use of Yield per Recruit Analysis could be an option in determining fish stocks, especially in situations where historical data in time series is insufficient. In this connection, a pilot study using Yield per Recruit Analysis was carried out in Sakon Nakorn Province, Thailand, to determine the stock status of the beardless barb in Nam Oun Reservoir. Results of such study could be used as model in the development of the appropriate management measures for the sustainability of the fishery resources of Southeast Asia.

The M.V. Plalung I of SEAFDEC serving as model for Thai trawlers Silapajarn, Kom; Rajruchithong, Sutee When the Government of Thailand was confronted with the need to address the pressing international requirements on labor in the fisheries sector, more particularly in trawl fisheries, SEAFDEC offered its 17-GT Thai-style trawler, the M.V. PLALUNG I as a demonstration boat as it resembles that of a typical Thai trawler. The M.V. PLALUNG I was acquired by SEAFDEC in 1982 through funds provided by the Government of Thailand, and was intended to be used by the SEAFDEC Training Department (TD) during its conduct of onboard practical training on fishing technology, navigation, onboard fish handling, seamanship, marine engineering, and fishing vessel operation in general. As a demonstration fishing boat, the M.V. PLALUNG I would showcase the efforts of the Government of Thailand in providing fishers and fishing vessel crew decent working conditions onboard fishing vessels. However, such action called for the modification of the design and structures of the M.V. PLALUNG I to be able to serve as a model for Thai trawlers. Thus, the Department of Fisheries (DOF) of Thailand collaborated with SEAFDEC, the Thai Union Group, and Nestlé Thailand to pursue the three-year project (2016-2018) aimed at modifying the design and reinstalling the structures of the M.V. PLALUNG I with financial and technical support provided by the Thai Union Group and Nestlé Thailand.

Beyond capacity adaptation – for what should it be adapted? Hagberg, Jacob It is well known that keeping fish stocks at optimum stock sizes will increase the production of fish leading to larger profits for fishers and increased food production. The Southeast Asian countries have started to make efforts to adapt fishing capacity to the available amounts of fish. But the step to translate scientific recommendations into a practical change of the fishing effort is often the most sensitive, especially from decision making perspectives. Decision makers feel pressured to meet the demands of different interest groups, often sacrificing the long-term larger profits for more short-term smaller gains. One solution to simplify this process is to use Harvest Control Rules.
