DNA Analysis of Indo-Pacific Mackerel from Cambodia and Viet Nam

Under the support from SEAFDEC/Sweden Project, a field trip was conducted to collect samples of tissues of Rastrelliger brachysoma (Indo-Pacific mackerel) for DNA analysis. The sample collections were conducted at the fish landing sites in coastal provinces of Cambodia (Koh Kong, Sihanouk, and Kampot Provinces) on 30 March to 2 April 2018 and in southern part of Viet Nam (Phu Quoc, Ha Tien, and Kien Luong Provinces)  on 6-11 April 2018. The field trip was facilitated by the project staff in collaboration with the Fisheries Administration of Cambodia and Research Institute for Marine Fisheries of Viet Nam. The DNA sampling was carried out by researchers from Kasetsart University together with the national focal points based on the standard operating procedure on DNA sampling of R. brachysoma which was developed through the activities of this project.

This research work has been initiated since 2017 under the agreement among the Gulf of Thailand countries to jointly study the fisheries stock structure of R. brachysoma in the Gulf of Thailand. The collected tissue samples included 64 samples from Cambodia and 95 samples from Viet Nam. While the DNA analysis is being done, samples from Malaysia and Thailand will be collected also. A technical meeting will be organized in September 2018 to disseminate the results of DNA analysis. Thereafter, the results of the stock structure will be used as inputs to the Gulf of Thailand’s monitoring, control and surveillance network for formulation of a joint management plan for the sustainable fisheries of R. brachysoma in the Gulf of Thailand.
