Effect of feeding rate on the survival and growth of milkfish (Chanos chanos) fry in a controlled environment

Abstract

The optimum daily feed allowance varies with species, age, size, frequency of feeding, culture procedures, quality of feed and water quality. This experiment indicated that with a diet containing 40% protein and 3,450 kcal of M.E. per kg, a feeding rate of 16-20% of the biomass is optimum for satisfactory survival and growth of fry raised in a controlled environment. Increasing the feeding level beyond this value was not beneficial but in turn increased the ammonia-nitrogen concentration to a level which is harmful to the fish.
