The composition and relative abundance of fish species assemblage of a mangrove creek in the Niger Delta, Nigeria based on different types of gear was assessed at four stations between November 2004 and June 2006. The overall community structure was made up of 25 species of 16 families. Visual observation showed that tilapia species comprising of Sarotherodon melanotheron and Tilapia guineensis were the most dominant species. Samples from baited entrance traps indicated that S. melanotheron dominated T. guineensis. Samples from baited hook and line, and cast net showed dominance of P. elongatus followed by P. quadrifilis. (The baited hook and line is commonly used by the fishers because it is effective in catching diversity of species, except that it is unable to catch bottom feeders such as mullets and tilapia species). Funnel entrance trap had the highest species selectivity, catching only tilapia species. Cast net was more selective in species catch than baited hook and line, but it was effective in catching both pelagic and benthic species. Among the fish species, members of the families: Sciaenidae, Polynemidae, Ariidae, Monodactylidae and Cichlidae were permanent residents; Carangidae, Luthjanidae and Serranidae were temporary residents; while Elopidae, Gobiidae, Dasyatidae, Cynoglossidae, Sphyraenidae and Trichiuridae were rare species.

Food And Feeding

The food and feeding habits of eight (8) fish species Elops lacerta, Chrysichthys auratus, Schilbe mys-tus, Sardinella maderensis, Synodontis schall, Hepsetus odoe, Tilapia zillii and Mugil cephalus in Ogun estuary, Ogun State, Nigeria were studied and estimated for six months, between February and July, 2014. A total of 470 fishes were randomly collected from the commercial fishermen during the study. Results from the stomach contents analysed using frequency of occurrence and numerical methods showed that S. mystus, E. lacerta, S. maderensis, H. odoe, S. schall, T. zillii, M. cephalus and C. auratus were predators, piscivores, herbivores, piscivores, omnivores, herbivores, herbivores and omnivores respectively while H. odoe and S.mystus partly fed on E. lacerta and T. zillii respec-tively. The Diet Breadth (D) ranged from 0.76 to 0.88 and the percentage Gut Repletion Index (GRI), a reflection of frequency of feeding, ranged between 60-100%.

Food And Feeding

Mugil cephalus is a permanent and abundant fish species in coastal, estuarine or lagoon ecosystems. This species was sampled in the lagoon of Grand-Lahou (Cote dIvoire) for the study of its diet and its feeding ethology. Stomachs were removed and their contents identified using identification keys to determine the diet. 88 specimens of M. cephalus were examined for food and feeding habits. 42 (47.72%) of the fish had empty stomach. Analysis of stomach contents showed that phytoplankton is the most consumed with a numerical percentage of occurrence of 94.98% (Cyanobacteria, Chlorophytes, Diatoms) and a percentage of occurrence is 64.9%. The proportion of zooplankton is 4.98% (cladocerans, copepods, foraminifera, rotifers and nematodes) according to the numerical percentage and 18.77% according to the frequency of occurrence. Detritus has an occurrence percentage of 8.43 %. Diet is mainly composed of diatom.
