Abstract

Although crustaceans exhibit heritable variations in body color, the effects of body color and background color on culture performance and color parameters remains largely unexplored. Thus, this study investigated the effects of background color (white, black, and green) on the culture performance, color parameters, and carotenoid content of three different body color (red, white, and green carapace strains) juvenile Chinese mitten crab (Eriocheir sinensis). The results showed that the body color significantly influenced body weight (P < 0.05), whereas the background color did not exhibit any notable influence on the culture performance. Body color and its interaction with background color significantly altered the lightness (L*), redness (a*), and yellowness (b*) of the carapace (P < 0.05). Moreover, body color and background color significantly affected the carotenoid content in the carapace (P < 0.05), although only body color exhibited a significant effect on total carotenoids in the inner membrane (P < 0.05). In conclusion, these findings highlight the importance of background color and provide new insights into the variations in body color of E. sinensis.

期刊介绍： Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture. The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more. This is the official Journal of the European Aquaculture Society.
