“…In addition to external lighting conditions, the selection of an appropriate background color for fish rearing holds significant importance. Research has underscored the profound impact of background color on various aspects of fish biology, particularly in terms of pigmentation [10,133]. Fish adapt to their background hues, leading to changes in their body coloration.…”

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.

“…In experiments with Takifugu rubripes , there was no significant difference in the growth of larvae under different light conditions. However, survival was significantly higher in larvae grown under 1.5 W m −2 (approximately 1024 lx) than 0.5 W m −2 (approximately 341 lx) (Liu et al, 2019a).…”

“…At 0 lx, melatonin in the plasma of Salvelinus alpinus increased approximately four times after the light was turned off. Low light intensity of 0.1–0.3 lx halved the level of melatonin in the plasma, and illumination of 50–65 lx further reduced its level to one‐quarter of the control group (Liu et al, 2019a).…”

Being one of the main environmental factors, the light factor influences many aspects of animal life. Photoperiod, light intensity (illumination) and wavelength are the primary periodic factors. There is a review that discusses the role of illumination on various life processes of aquatic anamnia vertebrates (fish and amphibians). The effect of light on the development, growth, respiration, consumption and efficiency of food conversion, hormone release, reproduction and behaviour of fish and amphibians has been studied. Illumination influences differently a significant number of physiological and biochemical processes and reactions of anamnia vertebrates at various development stages. The obtained results show that the nature of exposure to light is species-specific and corresponds to the ecological niche of species. Illumination influences both positively and negatively the development, growth and other physiological processes of fish and amphibians. Illumination plays a special role during the first feeding of fish in the environment and aquaculture. There are positive and negative behavioural responses of fish to light. However, it is not always possible to distinguish fish species with only a negative or only a positive reaction to light. The quality of the reaction can be influenced by the stage of development of eggs or larvae, age characteristics, feeding status, season, time, the physiological state of fish, morbidity, etc. A promising area of research is the study of the influence of light on the hormonal status of the body and reproduction of fish. Also, the light pollution and its influence on the physiology of anamnia vertebrates are important.

“…At present, the scale of breeding of T. rubripes is expanding in the coastal area of China. With increasing customer demand, the arti cial breeding of T. rubripes has become particularly important and optimal lighting regimes for arti cial environments are needed based on species and developmental phases (Liu et al 2019). More important for larval rearing, the lighting conditions need to be matched to the visual system of the target species.…”

Vision is the dominant sensory modality in fish and critical for the survival of fish larvae to detect predators or capture prey. The visual capacity of fish larvae is determined by the structure of the retina and the opsins expressed in the retinal and non-retinal photoreceptors. In this study, the retinal structure and opsin expression patterns during the early development stage of Takifugu rubripes larvae were investigated. At around two days after hatching days (dah), the yolk sac of T. rubripes disappeared, the mouth was clearly visible and the larvae started swimming and feeding on rotifers. Histological examination showed that at 1 dah, six layers were observed in the retina of T. rubripes larva, including the pigment epithelial layer (RPE), photoreceptor layer (PRos/is), outer nuclear layer (ONL), inner nuclear layer (INL), inner plexiform layer (IPL) and ganglion cell layer (GCL). At 2 dah, all eight layers were visible in the retina in T. rubripes larva, including RPE, PRos/is, ONL, outer plexiform layer (OPL), INL, IPL, GCL and optic fiber layer (OFL). By measuring the thickness of each layer, opposing developmental trends were found in the thickness of ONL, OPL, INL and IPL, GCL and OFL. The nuclear density of ONL, INL and GCL and ratio of ONL/INL, ONL/GCL and INL/GCL were also measured and the ratio of ONL/GCL ranged from 1.9 at 2 dah to 3.4 at 8 dah and no significant difference was observed between the different developmental stages (p > 0.05). No significant difference was observed for the INL/GCL ratio between the different developmental stages, which ranged from 1.2 at 2 dah to 2.0 at 18 dah (p > 0.05). The results of quantitative real-time PCR showed that the expression of rhodopsin, LWS, SWS2, green opsin, rod opsin, opsin3 and opsin5 could be detected from 1 dah. These results suggested that the maturation of eye of T. rubripes occurred during the period of transition from endogenous to mixed feeding, explaining the need for vision-based survival skills during the early life stages after hatching and for the overall ecology and fitness of T. rubripes.
