On the fish catch and discard of the shrimp fishery of Nigeria.

Commercial landings and effort data over the period 1970-1980 as well as shrimp research vessel catches were analysed. Both shrimp and fish by-catch consistently showed seasonality in abundance. However, while shrimp catches declined from 49.20% of total in 1979 to 13.795 in 1980, incidental fish landings rose proportionately. The fish shovelled overboard measured 18.0cm or less in total length. Prominent among these were Brachydeuterus auritus, Ilisha africana and Vomer setapinnis. The fish discard amounted to 43.68% of the total catch.
