Three types of box traps were set in Sorada reservoir of Ganjam District of Odisha as three treatments. They were Ghoni, Sepeti and Dori. These traps were set in replications in the three different stations of the reservoir such as Buguda, Khilabadi and Pankalabadi. The traps were designed in the three different ways. A small coconut piece was hanged in each trap by a wire. The traps were checked for the catch of fish and prawn in the early morning of each day except the closing season and unfavorable climatic conditions. The data base was created by taking the fish catch data. It was observed that, the catch of fish was more in the month of March-April and that of the prawn started in the month of May and went onwards up to September. The CPUE was calculated for each gear for the catch of fish and prawn. The results revealed that, the CPUE value for the trap Dori was 961.0 g/trap/day for the catch of fish and was 158.0 g/trap/day for the catch of prawn. Therefore, it can be concluded that, Dori is the selective gear for the catch of both fish and prawn

The results revealed that, the CPUE value for the trap Dori was 961.0 g/trap/day for the catch of fish and 158.0 g/trap/day for the catch of prawn. Therefore, it can be concluded that, Dori is the selective gear for the catch of both fish and prawn. Further study is necessary for different nets used in harvesting the fish and prawn from the reservoir also. Acknowledgement. The research work has been done as a Master degree research work.
