Fish trap fishery is one of the most important small-scale fisheries in Thailand. Fish trap used all over the world. Fish trap is a type of passive fishing gear that allow fish to enter and then make it hard for them to escape. The main target species are fish. Rayong province is one that the fish trap widely used for small fishery. It is used throughout the coastal areas to catch a variety of coral reef fish. But there were very few of fish behavior underwater observations to understand the capture process of fish trap research in Thailand, Attempts to modify Fish trap or improve fishing efficiency in the fisheries future may prove more easy if understanding of fish behavior in Fish trap (Bardach and Magnuson, 1980) The study of fish behavior in Rayong fish trap have not been investigated by using underwater camera system. In situ Underwater camera observations have even been to use for fish behavior research work all over the world, Cole et al (2004) used video camera recordings of entries and exits from blue cod pots for improve the fishing efficiency, Renchen et al. (2014) studied on the fish behavior responses to fish trap by using underwater video camera. such underwater camera observations have not been conducted for Rayong Fish trap fisheries in Thailand. This study focused on the investigating fish shows behavior inside fish trap by using two underwater cameras surveillance in Rayong coastal area.
