Color can impact the price of shrimp, with dark red preferred in some markets. Research using colorimeters to quantify color in raw and cooked shrimp found that although shrimp raised on white or black substrates exhibited different coloration, total carotenoid levels were the same in all the animals.
Health & Welfare
Coloration in crustaceans is affected by a combination of factors: diet, environment and genetics. The genes required for coloration are not present in any other animal, but crustaceans use them to create a variety of colors and shell patterns.
