Abstract
Effect of live feed on the growth and survival of Catla catla fingerlings fed live feed. Due to the rising cost of fish meal and other ingredients, the fish feed company is currently searching for new sources of protein. Fish naturally eat insects, which are a great source of protein. The waste products of the silk reeling business, silkworm pupae, have a high nutritional value and are a great alternative to fish meal. With 50-70% crude protein and 24-33% crude fat in dry pupae, it is an excellent insect source of protein that contains a rich, balanced quantity of essential amino acids. Catla catla fish were used in the experiment. Four different meals were used: three which increased the protein from the conventional food at 25%, 50%, and 75% levels with silkworm pupae, while the fourth was a control feed made up of GNC and corn. 50% and 75% silkworm pupae feed produced the highest results when compared to 25% and control feed.
