Preliminary studies on the food and feeding habits of Synodontis membraneceus from Ogobiri River, Nigeria
The food and feeding habits of Synodontis membraneceus of Ogobiri River of Bayelsa State, Nigeria was studied using 44 male and 51 specimens that were bought from fishers in the study area measuring between 5 and 25 cm total length. The Numerical and the frequency of Occurrence method of analysis were used. For the males, the food items by the numerical method were copepods (168), insects, (118), Cladocera (69), and unidentified items (32). In the female specimens, the food items were Cladocera (286), Insect (216), Copepod (100) and unidentified organisms/materials (65). In the Frequency of Occurrence method for the males, Copepod was still with a total of (48), Cladocera (44), Insects (29) and unidentified (16). For the females, Cladoera (48), Insects were (30) by Copepods (35) and unidentified (19). The Percentage composition of food items by the Numerical method was Cladocera (45.5%), Insects (34.5%), Copepod (12.5%), and unidentified items (7.0%) while the Percentage Frequency of Occurrence was, Cladocera, (30.5%), Insects (30.9%), Copepod (29.6%), and unidentified items (9.0%).
