---

Fish behavior is affected by environmental condition, including photoperiod. To understand the effects of different photoperiod toward O. hypophthalmus behavior, a study has been conducted in Oktober 2015. The fish was reared in fiber tanks size 100cm X 50cm dan height 40cm with water circulation system. The tanks were placed under plastic tents that were completed with light bulb and timer to adjust the time. There were 5 treatments applied, namely Control (natural photoperiod), 24 hours dark (24D), 16 dark and 8 hours light (16D8L), 8 dark and 16 hours light (8D16L) and 24 hours light (24L). Fish behavior was monitored hourly for a 72 hours period continuously. Swimming and schooling activities, fish position and respons to light and food were noted. Results shown that the photoperiod clearly affects the behavior of fish. During the dark, fish tend to be in the surface, swimming actively, do not form a group, sensitive to light and very agresive to take food provided. In contrast, during the light period, fish less active, tend to form a group in the bottom of the tank, less sensitive to light and less aggresive in taking food. Based on data obtained, it can be concluded that photoperiod is affect the behavior of fish in general. Keywords: photoperiod, Ompok hypophthalmus, Behavior, Dark, Light
