Feeding biology of ribbonfish, Lepturacanthus savala (Cuvier, 1929) off Ratnagiri coast, Maharashtra

International Journal of Fisheries and Aquatic Studies · 2014 · Vol. 1(3) · pp. 123–129

Abstract

Lepturacanthus savala is a highly carnivore fish, feeding mainly on fish, crustaceans and cephalopods etc. Fishes were observed to form important food item and were mainly recorded in L. Savala of the size group 30-40 cm to 60-70 cm. Cannibalism had also been recorded by the presence of juvenile ribbonfishes in the guts of bigger L. Savala. Index of fullness showed a peak in September (280.98) but it was low during April (83.24) and November (122.93) suggesting probable cessation of feeding during spawning season. The period of low digested matter and empty guts coincided with the two spawning peaks, suggesting that the fish preferred not to feed during the spawning months.
