Feeding ecology of two megrims Lepidorhombus doscii and Lepidorhombus whiffiagonis in the western Mediterranean (Gulf of Valencia, Spain)

The stomach contents of 344 four-spotted megrim, (Lepidorhombus boscii) and 159 megrim (Lepidorhombus whiffiagonis), off the eastern coast of the Gulf of Valencia (Spain), were analysed. The two species examined do not appear to have very similar diets, based on the species composition of prey. The vacuity coefficient is not high for any of the species, the main food being Crustacea (Decapoda and Mysidacea). Also Amphipoda and Teleostei are compo nents of the diet. Variations in the food of both fish related to their len gth show few small crustaceans as prey of the major specimens. Finally ther e was evidence for seasonal variation of the quality and quantity of the fo od consumed. There was no great dietary overlap between these two species.
