Thai marine fishery consists of two segments, the coastal fisheries, and oversea fisheries. The coastal fishery along the Andaman Sea is multi-gear and not exclusively for tuna fishery except for tuna-like by purseine. The organization's collectings coastal marine fisheries data are Upper Andaman Sea Fisheries Research and Development Center(Phuket) and others organizations along the Andaman Sea in fisheries department. Over sea fisheries in Thailand has conducted and reported tuna catches from two sources. The first one from Thai fishing vessels that go fishing in the high sea or water under the jurisdiction of the other country. The second, data comes from fishing boats on board at fishing ports. However, tuna fisheries from Thai vessels are not active during 2016-2017. So, the tuna data from Thailand has only been reported by tuna from foreign tuna vessel and tuna-like from purse seine landing in Phuket ports and along the Andaman Sea. The tuna vessel comes to landing at Phuket ports. There must be a procedure for reporting the type and amount of harboring. Follow the steps set by Fish Quarantine and Inspection Division. This is consistent with international principles. Operated by Phuket fish inspection office. Therefore, the sampling program can only be compiled by the record of Fish Quarantine and Inspection Division, such as Flag state, fishing area, trip date, port of loading, fishing gear, type and amount of each species. However, Thailand has collected data on catches of marine fisheries and report as the fisheries statistics of the country.
