Abstract
Aquaculture is poised for robust growth in India and availability of the nutritionally balanced feeds at a reasonable cost is the challenge to the aqua nutritionists. Supplemental feeds which provide additional quantities of nutrients are required when the productivity of a water body cannot provide for the fish growth desired. Continued growth and intensification of aquaculture production depends upon the development of sustainable different protein sources in aqua feeds. The feeding trials were conducted in carps (catla, rohu and common carp) to assess the influence of four different feed ingredients (spirulina, shrimp head meal, squid meal and soya flour) on the growth. Four different experimental diets were prepared and fed to experimental fishes. The highest mean weight gain (0.285g) was observed in catla fed with fish meal followed by common carp (0.205g) and rohu (0.167g). Among all the feed ingredients fish meal ranked first in terms of growth in all the species of carp tried in the experiment followed by shrimp head meal.
