“…For transmission electron microscopic (TEM) sample preparation, skin samples (1 Â 3 mm) were washed five times in PBS, then fixed in 2.5% glutaraldehyde overnight at 4 C, and post-fixed in 1% osmium tetroxide for 2 h at 4 C. Samples were stained with 2% uranyl acetate overnight at 4 C in the dark and dehydrated in a graded row of acetone (50%, 70%, 90%, 100%, and 100%), infiltrated with Epon resin at room temperature for 12 h, then embedded in Epon812 (Serva Electrophoresis, Germany), and kept to polymerization at 70 C for 48 h. Ultra-thin sections (70 nm) were cut on a Leica microtome, and images were captured with an HT7800 TEM (Hitachi, Japan) (Sayed et al, 2021;Zhao et al, 2024).…”

The skin color of the large yellow croaker (Larimichthys crocea) is a crucial indicator to determine its economic value. However, the location of pigment cells in the skin structure is uncertain. To determine the pigment cell type in the skin, the vertical order and ultrastructure of pigment cells were examined using light microscopy and transmission electron microscopy. Both dorsal and ventral skins comprise the epidermis, dermis, and hypodermis. Xanthophores, melanophores, and iridophores were observed in the dermis of the dorsal skin, whereas the latter two were in the dermis of the ventral skin. Interestingly, the size of xanthophores in the dorsal skin was significantly smaller than that of xanthophores in the ventral skin; however, the density of dorsal xanthophores was significantly higher than that of ventral xanthophores. The type L‐iridophores with large crystalline structures were observed in the uppermost area of the upper pigment layer, which contributed to the strikingly metallic luster shown by the ventral skin. The melanophores were exclusively found in the dorsal skin, offering the purpose of camouflage. Taken together, our results indicated that the pigment cells display different arrangement patterns between dorsal and ventral skin, and the golden color in the ventral skin results from the coexistence of light‐reflecting iridophores and light‐absorbing xanthophores.

“…For instance, Atlantic mackerel (Scomber scombrus) subjected to elevated rearing densities may transition from green to blue hues [140]. Additionally, physiological responses to acute stress in teleost can evoke a rapid whitening of body coloration, a phenomenon attributed to the prompt release of adrenaline into the bloodstream [13]. These multifaceted interactions underscore the intricate interplay between environmental factors and fish pigmentation within aquaculture systems.…”

“…are valuable due not only to their vibrant color but also to their taste and nutrition [11]. The market value of the leopard coral grouper (Plectropomus leopardus), for instance, increases with the intensity of its red body coloration [12,13], underlining the economic importance of pigment traits. Consequently, the controlled and effective enhancement of color traits through genetic selection remains a focal point in aquaculture.…”

Fish exhibit a broad spectrum of colors and patterns facilitated by specialized cells known as chromatophores. The vibrant coloration of fish, controlled by complex genetic and environmental interactions, serves critical roles in ecological functions such as mating, predation, and camouflage. This diversity not only makes fish an invaluable model for exploring the molecular mechanisms of pigmentation but also significantly impacts their economic value within the aquaculture industry, where color traits can drive marketability and breeding choices. This review delves into the sophisticated biological processes governing fish pigmentation and discusses their applications in enhancing aquaculture practices. By exploring the intersection of genetic regulation, environmental influences, and advanced breeding techniques, this review highlights both the scientific understanding and practical applications of fish coloration, providing a bridge between basic biological research and its application in commercial aquaculture.
