Adding colour enhancers to feed is an important aspect of nutrition in aquaculture and ornamental fish
It should be noted that scale and skin colour is one of the most important quality criteria determining the market value of fish, in addition to its impact on the physiological, behavioural and welfare conditions of captive-bred animals
In an overview, the pigments involved in fish colouration include melanin, guanine and carotenoids. Melanin and guanine can be produced by most fish and therefore do not need to be supplemented in the diet, but fish are not able to synthesise carotenoids de novo, and therefore these pigments must be obtained from dietary sources. In this scenario, the green microalgae Dunaliella and Haematococcus represent natural sources of two major carotenoids, β-carotene and astaxanthin, respectively.
These two pigments are responsible for the pink/orange/reddish skin pigmentation in a wide range of both food and aquarium fish species, as has already been demonstrated after dietary supplementation in commercially important fish. Furthermore, the high dietary efficacy of Dunaliella and/or Haematococcus in enhancing natural color is based on a number of scientific reports conducted on the most important aquarium fish species.
