Caloric values of the ingested food of the grey mullet mugil cephalus linnaeus

H.P. Das

Abstract



Estimates of organic carbon of the fish Mugil cephalus L. and its ingested food were made for a period of one year. The ratio of body carbon to ingested food carbon ranged between 2 to 7. The average percentage of organic carbon of the fish was 45.86. It was found that when the body carbon was high, the food carbon was low. An increase in the organic carbon content of the fish was noticed during the spawning period. From the carbon content the caloric values of the ingested food and of the fish were determined. The energy units (calories) of ingested food were high in the months of February and September while the energy units (calories) of the fish was maximum during January and August
