CAROTENOIDS FROM SHRIMP WASTE AS A NATURAL DYE FOR THE FEATHER COLOURING OF CANARY BIRDS Serinus canaria domestica
Carotenoids are naturally occurring pigments in plants, algae, fungi, insects, and crustaceans. Krill and prawns contain high levels of some value-added nutrients for the aquaculture industry, such as astaxanthin which is used as a colouring agent. In birds with ornamental plumage, such as canaries,...
