Summary

Skin pigmentation in fish is of great physiological, behavioral, and ecological importance. The sophisticated chromatic properties exhibited by this class of vertebrates provide protection from predators and contribute to inter- and intraspecific territoriality, crypsis and survival. For cultured species skin color not only is a prime factor of fish welfare and quality of product, but also plays a decisive role for acceptance of the product by the consumer and for market price. Wild Sparidae enjoy a widespread appreciation by consumers. Under cultured conditions, however, red sparids exhibit significant dispigmentation problems, considerably reducing their market appeal. For this reason, the coloration of cultured sparids has attracted the attention of scientists and fish farmers in the past decades. This research, as well as the neuroendocrine, environmental, and husbandry-related factors that regulate skin color, and critically reviewed in the following chapter.
