The Significance of Carotenoids in Fish: Impact on Health, Growth, and Coloration

Abstract

Carotenoids are naturally occurring pigments widely distributed in nature, known for their role in the coloration of plants, algae, and animals. In fish, carotenoids are primarily responsible for pigmentation, and they also play vital roles in promoting health, growth, and immune function. This paper explores the significance of carotenoids in fish, focusing on their sources, their biochemical roles, and their effects on fish health, growth, and coloration, particularly in aquaculture. Carotenoid supplementation in fish diets is an essential factor influencing the quality of farmed fish. The paper also discusses challenges in carotenoid use in aquaculture and the nutritional benefits for human consumers. Furthermore, the importance of carotenoids in promoting antioxidant activity and immune response is highlighted through experimental results and statistical analyses.
