Abstract

The influence of Spirulina platensis meal on the growth and carcass composition of two Indian major carps, catla, Catla catla and rohu, Labeo rohita was investigated in a 90-day culture trial. Four experimental diets were used and Spirulina replaced fish meal protein from the standard diet at 25%, 50%, 75% and 100% levels. There was no significant difference in the final weight attained by catla at all levels of Spirulina incorporation as compared to the fish-meal-based control diet. However, the replacement of fish meal by more than 25% Spirulina resulted in significantly superior growth of rohu. The specific growth rate and protein efficiency ratio recorded in rohu improved with higher levels of Spirulina inclusion, while in catla they did not differ significantly from the control treatment. In both the species, the digestibility of dry matter, protein and fat was found to improve marginally with increasing levels of Spirulina incorporation. The carcass composition showed an inverse relationship between protein and fat deposition. In general, fish fed with Spirulina diets had a significantly higher percentage of fat. The study demonstrated the usefulness of Spirulina for partial or complete replacement of fish meal in the diets of catla and rohu.
