Abstract

A study on the growth (Length-weight relationship and condition) of the Jack Cravelle (Caranx carangus) in Isi-Okwani Estuary Oyorokoto was conducted to provide key basic data that are very useful in the management of the stock. The length-weight data by means of regression indicated that the fish growth was negatively allometric (2.0046±0.0793), while the overall condition of the fish was good (1.29) the condition factor peaked in September and dipped in October. The Index of Relative importance technique used for its stomach content analysis revealed that shrimps were the most important (most consumed) food item. Palaemon africanus was the most preferred shrimp with a percentage value of 60.21 while Palaemon maculatus contributed 39.79 percent of shrimp consumption. Other items found in the fish’s stomach were teleost 0.13 percent and unidentified items 34.57percent. Caranx carangus in Isi-Okwani Estuary was carnivorous specializing in shrimps especially Palaemon africanus.
