Nigeria has an extensive coastline of approximately 900km and an Exclusive Economic Zone (EEZ) of about 217,313 km² (SeaAroundUs, 2007). Within the nation’s EEZ, there is abundance of Sardinella and bonga and extensive breeding and feeding grounds for prawns. Because of the high export value of these prawns, many trawlers engage in shrimping with small mesh codend trawl nets less than the stipulated 44mm, which expectedly exploit not only shrimps but juveniles of important commercial fish species stipulated for exploitation with 76mm trawl codend. In addition to fishing with illegal mesh sizes, the shrimp trawls also shrimp in shallow areas (less than 20m depth or 5nm strip) reserved for the artisanal fisheries by law. The bycatch from shrimping made up of small sized fishes were initially dumped in the sea, but because of the waste of biomass they were later permitted to be landed and sold to fish traders. This has created the danger of overfishing of the important commercial fish species by shrimp trawlers. I
