Abstract:
Black carps have a high demand due to their unique black colour. Local breeders, however, experience a dull brown-black colour in black carps, giving them a low market value. Aim of the present study was to increase the melanin pigments in black carp skin incorporating squid ink (Loligo spp) powder into fish diets. Diet A was prepared with commonly used fish feed ingredients (100%), whereas Diet B and Diet C had the same ingredients (99.9867% and 99.9733%, respectively) and made into 100% by adding dried squid-ink powder 0.0133% and 0.0267% respectively.
