The Food of the Demersal Fish of a West African Estuary Export

@article{Longhurst57, abstract = {1. The demersal fish of the Sierra Leone River can be divided into three categories on the basis of their diet: those which are almost exclusively ichthyophagous, those which feed on the more active members of the invertebrate epifauna together with some fish, and those whose diet is based on the invertebrate infauna and the sedentary epifauna. 2.
