Effects of Feeds Enriched with Exogenous Enzymes on the Growth, Flesh Composition and Platability of an Indian Major Carp, Cirrhinus cirrhosus (Bloch, 1795)

In response to the increasing use of exogenous enzymes in carp polyculture systems in Bangladesh, a study was conducted to evaluate the effects of feeds enriched with exogenous enzymes on the growth, flesh composition, and palatability of an Indian major carp, Cirrhinus cirrhosus. This feeding trial was conducted over 90 days in 12 cages in a fish pond at University of Rajshahi, Bangladesh. A commercial feed additive (Aquazyme Plus) was used as the enzyme source at concentrations of 0.0, 2.0, 4.0, and 6.0 g/kg feed to prepare four test feeds, designated as the following treatments: T1 (control), T2, T3, and T4. Growth and feed utilization parameters, flesh composition, and organoleptic qualities of cooked flesh were evaluated using standard formulas, methods…
