Shrimp by-catch species from industrial shrimp trawl fisheries in Lagos, Nigeria coastal waters
A fisheries-dependent surveys was conducted to identify and quantify the species composition of shrimp by-catch and its effect on fishery sustainability. Samples were bought monthly, from October 2009 to June 2010 from landings site, at Apapa-Liverpool market Lagos. 25 fish species belonging to 18 families targeted in other inshore fisheries constituted the by-catch species. The percent of weight compositions of some economically important by-catch species were: Pseudotolithus senegalensis (5.76%),Ilisha africana (14.65%), Pentanemus quinquarius (2.94%), Pteriscion peli (6.60%), Galeoides decadactylus (3.17%), Cynoglossus senegalens is (6.76%) and Chloroscombrus chysurus (10.81%). About 80% of the shrimp by-catch species were juvenile fin fish. However, continuous harvest without appropriate mitigating measures poses a threat to sustainability of coastal capture fisheries. Recommendations are proffered in order to conserve the resources for sustainable development.
