Abstract: The objective of this study was to khow the distribution underwater light intensity and fish behavior in fishing process of boat bagan. The data were collected through observation to fishing process, measurement of under water light intensity using marine under water lux meter, fish behavior using fish finder based on hauling time before mid night (19:00-00:00) and after mid night (01:00-05:00. The data analyzed comprise catching process, distribution of under water light intensity,and fish behavior. The results of the study indicate that illumination of light detected under water is 21 m vertically and 12 m horizontally with the value of each illumination is 0.1 lux and 3.0 lux from the center of light. The choice of illumination zone by the fish before mid night is 8-1,5 lux at the depth range 15 - 20 m and after mid night at the illumination 8 - 1,5 lux at the depth range 10-15 m of illumination 8-1,8 lux. During fishing process, the fishes were concentrated at 8 - 1,8 lux more than others zone.
