Five new feeds, formulated using different combinations of soyabean meal, squilla meal, fish meal and sardine oil, were evaluated in a field trial over 98 days vis-à-vis a fish meal-based standard diet on the growth and organoleptic quality of common carp. Of the five treatments tried, the soya-squilla combination enriched with 5% oil induced higher growth and proved to be the best, yielding an increase of 25% body weight over that obtained with the fish meal-based control diet. Digestibility, conversion and organoleptic quality were also found to be relatively better with this diet. The final fish weights obtained with the soya-fish meal combination and soyabean meal enriched with 8% sardine oil were lower by 8·2 and 4·8% respectively, than that of the control. The two diets containing higher levels of squilla meal resulted in poor growth. The results indicate the possibility of using squilla meal, reported to be adequate in lysine and methionine, at a reduced level in combination with soyabean meal, known to be deficient in available lysine and methionine, as an economic substitute for fish meal in carp diet.
