“…Other than that, the inclusion of marigold petals in the feed improved the growth of European seabass, Dicentrarchus labrax (Goda et al, 2018). Judan Cruz et al (2021) found that feeding juvenile red tilapia with the inclusion of Daucus carota peel and Ipomoea aquatica leaves in the feed improved the growth performance. On the other hand, the addition of rounded brittle fern weed, Laurencia obtuse as a natural carotenoid in the feed for rainbow trout, Oncorhynchus mykiss resulted in lower growth compared to the control treatment (Baki et al, 2018).…”

Red tilapia (Oreochromis sp.) is a highly produced aquaculture fish among freshwater species. Coloration is an important factor in determining consumer preferences. Therefore, an 8-week experiment was conducted to enhance the growth performance and body coloration through the inclusion of torch ginger in the feed of red tilapia. Five experimental feeds were prepared from commercial feed (crude protein: 34%, crude lipid: 5%) containing torch ginger powder at 2.5, 5.0, 7.5, and 10% (T1, T2, T3, & T4) inclusion levels while feeding without torch ginger act as a control (T0). Red tilapia (Initial body weight: 0.4±0.1g; Initial total length: 4.0±0.1cm) were distributed at stocking number 20 fish/tank into fiberglass tanks with a capacity of 80 L and triplicates for each treatment. The fish were fed with experimental feeds until satiation. The growth of fish was significantly higher (P<0.05) when the fish fed with T1, T2, and T3 compared to control treatment T0. Moreover, the feed intake was significantly increased (P<0.05) when the torch ginger powder was added to the experimental feeds. In addition, the FCR was significantly better (P<0.05) when the fish fed on T1, T2, and T3 compared to T0. The inclusion of torch ginger powder in the feed did not significantly affect (P<0.05) the body protein and lipids of the experimental fish. The increment of redness was significantly higher (P<0.05) when the fish fed with T1, T2, T3, and T4 compared to T0. However, it showed a declining trend of redness when the inclusion of torch ginger increased to 5.0% and above. Thus, the present study suggested that the inclusion of torch ginger powder improved the performance and enhanced the body coloration of juvenile red tilapia. However, a further increase of torch ginger powder by more than 2.5% did not help in the enhancement of the body coloration.

“…New investigations evidenced the intricacy of endogenous bioconversion and deposition of carotenoids in aquatic animals, which for the most part, was related to structural isomerism 95,96 . It was not until recently that researchers began to characterize and elucidate the diverse range of genes and pathways involved in the metabolism and deposition of exogenously derived carotenoids 90,97–99 . Exciting varieties of enzymes and transporter molecules linked to carotenoid‐based integumentary colouration in fish were suggested to be genetically controlled, analogous to findings in mammals and avians 94,100–102 .…”

Aquaculture continues to expand swiftly and remains the fastest-growing food industry worldwide amidst ever-present threats from chronic stressors and emerging diseases. Nutrition plays a pivotal role in the profitability and viability of the aquaculture industry that steered a paradigm shift to therapeutic nutrition. Carotenoids, also termed tetraterpenoids, have garnered considerable attention owing to their therapeutic attributes and immeasurable health benefits, which incited a surge in global demand. These biological pigments are recognized to promote immune systems and antioxidant defence mechanisms in both aquatic vertebrates and invertebrates. This review brings forth existing scientific evidence and underscores the notable roles of carotenoids as biologically active constituents with anti-stress and immunostimulatory potentials in farmed aquatic animals whilst explicating possible mechanisms of action. Empirical data unequivocally established the modulatory functions of carotenoids on endogenous antioxidant enzymes, innate and adaptive arms of the immune response, as well as the expression of multiple antioxidant and immune-related genes. The comprehensive information presented is beneficial to deepen our understanding of the utilization of carotenoids as potent stress alleviators and immunostimulants in cultured aquatic animals, which is translated into improved health.Advancements in aquatic animal health and welfare could principally contribute to reconstructing a more sustainable aquaculture industry. This article may be useful for subsequent investigations towards further advances in research and innovation to a greener blue revolution in solving the challenge of global food security.

The growth, immune response, and reproductive performance of broodstock of Nile tilapia (Oreochromis niloticus) under winter stress conditions were investigated the effects of supplementary diets with astaxanthin-enriched bacterium, Paracoccus carotinifaciens. Throughout an eight-week period in the winter season, male and female tilapia were fed with diets containing different levels of P. carotinifaciens dietary supplementation: 0 g/kg (T1; control), 5 g/kg (T2), 10 g/kg (T3), and 20 g/kg (T4). Subsequently, a four-week mating system was implemented during the winter stress period. The results revealed that there were no signi cant differences observed in growth, hematological indices, and blood chemical pro les among all treatment groups for both male and female tilapia. However, a signi cant increase in cholesterol content was noted in both male and female tilapia fed with the T4 diet (p<0.05). The total carotenoid content in the muscle was evaluated, and signi cantly higher values were found in both male and female tilapia that fed T4 supplementation (p<0.05). Moreover, immunological parameters such as myeloperoxidase and antioxidant parameters in the liver including superoxide dismutase activity and catalase enzyme activity showed signi cant increases in tilapia fed with the T4 diet. The impact of P. carotinifacienssupplementation on broodstock tilapia indicated a signi cant increase in spermatozoa concentration in males and increased egg production in females after consumption of the T4 diet (p<0.05). Thus, this study highlighted that the presence of astaxanthin-enriched bacterium P. carotinifaciensin the diet of broodstock Nile tilapia can lead to the accumulation of carotenoids in their muscle tissue, improvement in antioxidant status, enhancement of immune function, and potential enhancement of reproductive capabilities, even under overwintering conditions.
