Study on trash fish production from marine fisheries in Thailand during last three decades, related information on fishing gears, fishing vessels and fishing grounds, and information on trash fish utilization especially for aquaculture indicated that 35 percent of marine production was trash fish. In recent years trash fish production has been declining. However, it is likely that trash fish production fluctuates with the number of fishing vessels. About two-third of production comes from the Gulf of Thailand and otter board trawler contributes about 80 percent of total trash fish production. Most of trash fish production in Thailand is used as raw material for fishmeal production. Out of which, about 40 percent of fishmeal production is used as aquacultual feed. According to increasing of aquacultural farm, domestic trash fish and fishmeal seems to be insufficient due to limitation of available fishery resources and fishing vessels. Therefore, supplies from imported fishmeal and substituted feed ingredients are likely to support the trash fish demand.
