The objective of this study is to identify the pattern of fish behavior related to the operation of fishing gear using light. This research specifically aims to analyze the pattern of fish distribution before and after the capture process, to analyze the arrival pattern and to analyze fish behavior around the light source. This research was conducted in Barru Regency waters, Makassar Strait (4° 19’ 19,9\" S. Lat. – 119° 16’ 201\" E. Lon.) using Side Scan Sonar Instrument. Descriptive analysis was employed to examine the behavioral pattern around the given illumination area. The result shows that there are some fish came directly to the light source and stay in the vicinity of the illuminated area while others are outside of that area. The fish school approaching the illuminated area was found at the depth of 5-10 meters and 20-30 meters. The fish school movement speed approaching the Bagan Rambo reached 0.57 m/s and 0.21 m/s when fish school was around the illuminated area. The fish school tends to move in regular pattern encircling the light source and became concentrated once the light is turned off. In the illuminated area the shape of the fish school tend to be spherical, while outside of the area is tend to be in the shape of ribbon.
