Summary
Feeding and spawning activity of Caranx hippos (L.) was studied in off-shore waters and some lagoons in southern Ghana. The food of adult Caranx hippos was found to be predominantly Engraulis guineensis (Cuv.) followed by Sardinella eba (Cuv.). The food of juvenile Caranx hippos was either small fish of the species Epiplatys sexfasciatus (Stein) or the juveniles of caridian shrimps, Macrobrachium spp., or peneid shrimps, Peneus duorarum (Burkenroad).
The availability of the food in lagoons is inversely correlated with the height of the water. Digestion in the adult was found to be so fast that within 4 to 5 hours the food loses its identity.
Availability of food appeared to determine the distribution of Caranx hippos. Both adult and juvenile fish were found to feed mostly during the day.
There appears to be protracted spawning with most activity taking place between October and late January. Ripe fish, however, were rarely encountered. Juvenile Caranx hippos were present in the lagoon all the year round with minor variations in their abundance, depending on the overall water level.
