Background and Objective: published information on the food and feeding habits of the clupeid, E. fimbriata in Forcados river estuary which is a dominant and important economic fish species in the region is scare. This study would therefore provide vital information that could be used by other researchers for future studies. Materials and Methods: Stomach content was analysed using frequency of occurrence (Fi) and volumetric method. For food selectivity estimations the Ivlev index was adopted. Variation in the amount of food consumed by fish in relation to body mass was calculated using gastrosomatic index (GSI). The Gut repletion index (GRI) was calculated according to Ekpo et al. (2014). Results: Of these 1095 (96.73%) had food items while 38 (3.27%) had empty stomachs indicating that this species were active feeders. High GSI and GRI values were recorded. The species fed predominantly on Microcystis and accounted for 24.99% (the highest percentage) of the food items by percent occurrence frequency while Macrobrachium sp had the highest by percent volume of food (42.3%). The consumption of food items recorded in this study did not follow any seasonal pattern. The number of empty stomach was generally higher in the rainy season months than the dry season. The macroinvertebrate positively selected by E. fimbriata was Callinectes sp. Conclusion: The study indicated that E. fimbriata fed on phytoplankton as a major diet. |
