“…In view of increased attention being given to the stereoisomer configuration of astaxanthin in wild and cultured salmonids (ref. 20), further studies may prove feasible to determine any possible differences in the physiological functionality of the different isomers of astaxanthin. Finally, aquaculture product quality will be the focus of increased attention, notably nutritional attributes, sensory aspects, and establishment of optimal processing conditions for more effective postharvest utilization.…”

-Aquaculture is a rapidly growing global industry, comprising cultivation of various freshwater and marine species of finfish, shellfish, molluscs, and ornamental fish. By the year 2000, as much as 20% of the world production of fish will be based on aquaculture. Properly formulated feeds are a significant part of successful aquaculture. Carotenoids play a major role in culture of salmonids such as Atlantic salmon and rainbow trout. Various biological and nutritional roles for carotenoids in salmonids are documented along with the effect of biotic and abiotic factors on astaxanthin transport and retention and final flesh pigmentation. Relevant recent feeding results are presented. INTERNATIONAL DIMENSIONS OF AQUACULTUREGlobal moduct ion and growth Aquaculture, involving farming of a variety of freshwater and marine species of finfish, shellfish, molluscs, and ornamental fishes, is a rapidly growing global industry with a broad range of technological and managerial practices. In 1990 (ref. l), world aquaculture reached 15.3 million metric tons (MT), or 12.1 million MT, if aquatic plants were excluded. This is more than double that reported for the year 1975. Of this, approximately 50% was of freshwater origin, largely cyprinid species, while 6% was of marine origin. As much as 80% of aquaculture production is centered in Asia, particularly in China and Southeast Asia. During the 1984-89 period, capture fisheries expanded only about 14%, while aquaculture rose nearly 70%. Furthermore, the total value of world aquaculture production averaged an annual increase of 15% during the 1984-90 period. Market demand for quality product has stimulated much of the growth in aquaculture, especially for salmonids and marine shrimp species. The total world aquatic harvest in 1991, including aquaculture, was about 96 million MT of which aquaculture comprised about 16% (ref. 2). Harvest limitations in global fisheries suggest that further growth in aquatic production will depend upon aquaculture. Projections are for global aquaculture output to exceed 20 million MT by the year 2000, comprising about 25% of the world's seafood.Of cultured finfish, 85% are nonsarnivorous species, mostly cyprinids of various Chinese and Indian carp species. Almost half of the carnivorous species are salmonids, a ratio of about 50:50 salmon and trout. In the period 1986 to 1989, increases of 100-180% occurred in production of farmed Atlantic and Pacific salmon, while increases of 20-70% were recorded for common carp, tilapias, channel catfish, rainbow trout, and various species of marine shrimp, the latter comprising nearly 88% of crustacean aquaculture production. Global shrimp production alone in 1989 was over 530,000 MT, varying in volume and particular species with specific country. Successful cultivation of other marine finfish includes that of yellowtail, sea bass, sea bream, flatfish, grouper, and snapper. Numerous other marine and freshwater finfish are in various stages of evaluation for commercial aquaculture purposes. Salmonid brod...

“…For instance, to preserve cultured salmon natural muscle coloration diets for salmonid species include different types of carotenoid sources like synthetic astaxanthin and canthaxanthin (Torrissen, 1989;Bjerkeng et al, 1992;Storebakken and No, 1992), carcass meal from red crustacean (Satio and Regier, 1971;Kotic et al, 1974), certain algae or red yeast (Johnson et al, 1980). Carotenoids are also included in commercial diets for red sea beam to maintain good skin coloration (Katayama et al, 1965;Tanaka et al, 1976;Nakazoe et al, 1984).…”

“…Muscle tissue is the basic supplier of egg carotenoids in fish, and carotenoids absorbed through the intestine are stored in the muscle tissue before transferring into the skin and gonads during the spawning season (Bjerkeng et al 1992). Thus, increased levels of carotenoids in the muscle tissue support higher levels of egg carotenoid.…”

Carotenoid content and colour of eggs in migratory broodstock kutum (Rutilus frisii kutumKamensky, 1901) (Osteichthyes: Cyprinidae) in the Shirud and Tajan Rivers, south Caspian Sea

Carotenoids have a proven and positive impact on fish reproduction success. It is believed that highly pigmented eggs reflect the level of carotenoid content and this, in turn, has an effect on the viability of the eggs. Kutum, Rutilus frisii kutum, a species endemic to the south Caspian Sea, display different egg colours (yellow, orange or green) during the spawning season. In this study, we investigated the percentage of adult female kutum with the different egg colours, analysing the carotenoid content for each egg colour and the fertilisation rate for each egg colour in female migratory kutum in the Shirud and Tajan Rivers within the province of Mazandaran, Iran. The average of egg-carotenoid content of kutum in the Shirud River (6.63 ± 0.28 µg.g −1 ) was less than those for fish in the Tajan River (7.91 ± 0.27 µg.g, indicating a spatial variation in egg-carotenoid content of the fish. The orange and yellow eggs had more carotenoid than green eggs. Additionally, larger fish had a higher concentration of carotenoid compared with their smaller counterparts. The fertilisation of orange and yellow eggs was somewhat associated with egg-carotenoid content.
