Study was conducted to investigate the effect of underwater illumination pattern by using different lamp shade material on the total catch of boat bagan. The distribution of underwater light intensity of different lamp shade showed almost an oval shaped which decreased with increased depth. The light of lamp with aluminum shade can penetrate more deeper than plastic material. It can be identified that the aluminum material reflected light more intense than the plastic. The main catch was dominated by anchovy Stolephorus sp. The result shows that the total catch of aluminum material more effective than the plastic.
