A prelimnary study of diet in the juvenile gorean snapper, Lutjanus goreensis (Valenciennes, 1830) from Five Cowrie Creek, Lagos, Nigeria
Diet of the juvenile Gorean snapper, Lutjanus goreensis from Five Cowrie Creek was investigated between April 2008 and January 2009. Analyses of 184 specimens by numerical (NO), frequency of occurrence (FO) and geometric index of importance (GII) methods, respectively revealed a moderately high proportion (47.83%) of stomachs with food or prey. Shrimps and crabs constituted more than 80 % of total prey items. Other dietary components included lobsters, stomatopods, whole fish and fish parts. Similarly, analysis of diet composition by size - groups also indicated a predominance of the shrimps and crabs over all other prey items. In conclusion, L. goreensis can be described as a top-level carnivore feeding almost exclusively on epibenthic crustaceans in the juvenile stage.
