“…Similarly, in rats, supplementation with canthaxanthin did not affect growth rate even after 20 weeks of feeding 23 . In contrast, some studies have reported growth enhancement in rainbow trout 24 and Atlantic salmon 25 . Feed intake in the present study was not influenced by carotenoid levels and thus feed utilization did not vary.…”

SUMMARY: We attempt to assess the impact of different levels of dietary β‐carotene on immune function in rainbow trout. Semi‐purified diets containing 0, 40, 200, and 400 mg β‐carotene/kg dry diet were fed for 12 weeks to fish with average weight of 45 g. In addition to the humoral and cellular immune parameters, growth and feed utilization were examined. There were no marked differences in growth and feed utilization showing that β‐carotene was not particularly efficient in enhancing growth of rainbow trout. Of the immune parameters measured, total immunoglobulin was significantly highest for the 200 mg β‐carotene fed group. Serum complement activity (alternate pathway) at 200 and 400 mg β‐carotene supplementation was significantly higher than that of the unsupplemented group. An increasing trend in lysozyme activity was observed, however, the differences among the groups were not significant. Phagocytic activity was similar among diet groups except at the highest level of supplementation where it was the maximum. Oxygen radical production by peripheral blood leukocytes appeared to be lower at higher levels of carotenoid supplementation. Overall, dietary β‐carotene clearly enhanced immune response parameters in rainbow trout such as serum complement activity and total plasma immunoglobulin but did not show a definite influence for the other factors examined in the present study.

“…In salmonids, the amount of carotenoids retained in the flesh and the efficiency of retention are the ultimate measures of the availability of astaxanthin [30]. Liver, on the other hand, serves as the temporary storage as well as the principal metabolic organ of these compounds [31] but these are also secreted back to the plasma and transported to tissues that may require them (e.g., lymphoid organs) or taken up by circulating blood cells and thus may not reflect the true availability.…”

Astaxanthin is a high value keto‐carotenoid pigment renowned for its commercial application in various industries comprising aquaculture, food, cosmetic, nutraceutical and pharmaceutical. Among the verified bio‐resources of astaxanthin are red yeast Phaffia rhodozyma and green alga Haematococcus pluvialis. The supreme antioxidant property of astaxanthin reveals its tremendous potential to offer manifold health benefits among aquatic animals which is a key driving factor triggering the upsurge in global demand for the pigment. Numerous scientific researches devoted over a number of years have persistently demonstrated the instrumental role of astaxanthin in targeting several animal health conditions. This review article evaluates the current best available evidence to judge the beneficial usage of astaxanthin in aquaculture industry. Most apparent is the profound effect on pigmentation, where astaxanthin is frequently utilized as an additive in formulated diets to boost and improve the coloration of many aquatic animal species, and subsequently product quality and price. Moreover, the wide range of other physiological benefits that this biological pigment confers to these animals is also presented which include various improvements in survival, growth performance, reproductive capacity, stress tolerance, disease resistance and immune‐related gene expression.
