Abstract

The stomach content of the pink shrimp (Penaeus notialis) from Abonnema Creek, Rivers State Nigeria was studied for its food preferences. The fish’ gut content was studied using numerical and frequency of occurrence methods. Cyclotella atomia (46.09) was the most preferred food item based on analyses using index of food significance (IFS), Other items consumed were: (Bacillanophyceae) Melosira varians, Melosira distans, Cyclotella glomerata, Diatoma elongatus, (Cyanophyceae), Anabaena spiriodes, Spirulina sp, Raphidiopsis curvata. and (Chlorophyceae) Cladophora sp. Regression analysis of length-weight data showed that the fish growth was negative allometric (2.4059±0.0689), while condition factor which was estimated by the equation K = W/ aLb gave a value of 0.4073261±0.2018464. P notialis, fed mainly on algae in this study and therefore would perform well on a moderate protein compounded feed if raised in captivity.
