“…These results confirm the possibility of using G. persica as a natural pigment for skin colouration in fish. The intensity of colouration in Persian sturgeon was probably enhanced through carotenoids ingested and assimilated in blood and fillet ( Yeşilayer et al, 2020 ).…”

Algal seaweeds have abundant amounts of active substances and can be used as pharmaceuticals and biomedicals in aquafeeds. In this context, the powder of red macroalgae Gracilaria persica was included in the diets of Persian sturgeon at the rate of 0, 2.5, 5, and 10 g/kg to investigate its role on the growth rate, fillet colouration, haemato-biochemical indices, serum, and skin mucus immunity. The weight gain, SGR, and FCR displayed no significant changes in fish fed varying levels of G. persica ( P > 0.05). The level of total carotenoids was significantly higher in the blood and fillet of fish fed 5 and 10 g G. persica /kg diet ( P < 0.05). Dietary G. persica significantly altered RBCs, WBCs, a nd HCT at 5, and 10 g/kg, whereas the Hb was increased in fish fed 5 g/kg ( P < 0.05). The blood total protein and albumin were significantly increased in fish fed 5 and 10 g/kg ( P < 0.05). No significant alterations were observed on ALT, AST, ALP, and glucose levels of fish fed varying levels of G. persica ( P > 0.05). Serum Ig, lysozyme, superoxide dismutase, catalase, and respiratory burst activities were increased in fish fed 5, and 10 g/kg than fish fed 0 and 2.5 g/kg diet ( P < 0.05). The level of total protein and lysozyme activity in the skin mucus were significantly higher in the blood and fillet of fish fed 5, and 10 g G. persica /kg diet than fish fed 0 and 2.5 g/kg ( P < 0.05). Based on the obtained results, G. persica can be used as a feasible feed additive in the diets of Persian sturgeon at 5–10 g/kg diet.

“…Purity and brighter skin pigmentation were found in electric yellow chichlids (Labidochromis caeruleus) when they were experimentally fed with diets containing carotenoids extracted from marigold, nettle (Urtica sp.) and alfalfa (Medicago sativa) at a dose of 150 mg/kg of supplemented diet [54].…”

Emergence of Plants in Fish Pigmentation

Pigmentation plays a significant role in fish for consumer acceptability. Making and maintaining of aquarium containing pigmented ornamental fishes have evolved into a lucrative business in recent years. A number of pigments, primarily carotenoids are mainly responsible for the beautiful colouration of ornamental fishes. As fish cannot synthesize carotenoids de novo, there is a need of supplementation of carotenoids in the diet. Since natural sources of pigments are low-cost and more environmental friendly than the synthetic pigments, many studies have been carried out to test various plant-based natural carotenoids for enhancement of fish pigmentation. Forty-one plant species belonging to 28 families have been found widely used in imparting colouration to different species of fishes. Of these, 19 species were shown to be highly potential in fish pigmentation. Flowers, leaves, roots and whole plant are used in the study. Plant by-product like rice bran has also been used in fish pigmentation. The present review discusses about the potential plants used in fish pigmentation, their efficiency and the associative parameters along with the survival rate, growth and immune system promoter of the target species.

“…Nettle, marigold, alfalfa and zeaxanthin were added to the feeds of electric yellow cichlids. Weight gain, specific growth rate, feed consumption, total weight gain, feed conversion ratio and survival rate of the experimental groups were not found to be significant (Yeşilayer et al., 2020).…”

This study was done to assess the effect of the colouration of the red zebra cichlid (Maylandia estherae), using beet root red (Beta vulgaris ruba) and henna (Lawsonia inermis). The fish with an average weight of 1.21 ± 0.69 g was placed in 12 aquariums. Fifteen fish were placed in each aquarium. The fish were fed with diets which were without carotenoid supplement (AK), containing astaxanthin (AA), beet root red (AP) and henna (AI). Except the AK, each group contained 50 mg/kg carotenoid additives. As a result of the experiment, total carotenoid values between groups were not significant (p > .05). The redness (a*) value of groups was significant (p < .05), and the values of brightness (L*) and yellowness (b*) were not significant (p > .05). Samples were kept in the freezer at −20°C for 120 days to see whether the fish kept their colour. All groups decreased compared with the 50th day. This difference in groups except the AP was significant (p < .05). The FCR, SGR and weight gain% was not significant (p > .05). The survival was 97.28%, and it was the same in all groups. The study concluded that natural carotene sources with lower costs had similar effects with astaxanthin.
