Feeding habits of Macrodon ancylodon (Actinopterygii, Sciaenidae) in northeast, Brazil
The feeding habits of Macrodon ancylodon were studied based on 280 specimens from the Maranhão coast, northeast Brazil. The diet showed a predominance of fishes, crustaceans and occasionally cephalopods. The diets of males and females were similar and difference was found in the proportion of prey i...
