Feeding behavior of some carnivorous fishes (Serranidae and Scorpaenidae) from Tuléar (Madagascar)

Abstract

The feeding behavior of 8 species of sea basses (Serranidae) and 17 species of scorpionfish (Scorpaenidae) has been studied by quantitative analysis of their stomach contents. Most of the 459 specimens analysed were collected from the barrier reef of Tuléar (Madagascar). Examination of stomach contents revealed that in each species feeding behavior varies according to a nyctemeral rhythm, individual size of specimens, biotope and geographical area. Prey consumption by sea basses and scorpionfish on a reef tract is discussed in general terms. © 1976 Springer-Verlag.
