“…Goldfish (Dutch lion head) convert the yellow xanthophyl pigment zeaxanthin to the red carotenoid pigment astaxanthin through 4‐ketozeaxanthin (Hata & Hata 1972). Conversely, trout ( Oncorhynchus mykiss ) performs the opposite transformation that is the conversion of astaxanthin to zeaxanthin (Katsuyama, Komori & Matsumo 1987). Salmon and red sea bream ( Pagrus major ) do not convert xanthophylls to canthaxanthin or astaxanthin (Storebakken & No 1992; Torrissen 2000).…”

This study presents data on the e¡ect of carotenoid sources on skin coloration of red porgy (Pagrus pagrus). Three experiments were conducted: in the ¢rst, ¢sh were fed an astaxanthin (Naturose s )-supplemented diet, while the second ¢sh received diets supplemented with b-carotene (Rovimix b-caroten s ) or lycopene (Lyc-O-Mato s ): Carotenoids were added to the level of 100 ppm in each diet, while a non-carotenoid-supplemented diet served as a control. In the third experiment, the e¡ect of dietary protein/carbohydrate ratio on melanin content in the skin was investigated. For this experimentation, four diets were formulated to contain 50/23, 40/32, 30/48 and 20/59 protein/carbohydrate ratio. Naturose s astaxanthin increased total carotenoid content in the dorsal skin area while b-carotene and lycopene seem to have had no signi¢cant e¡ect. Naturose s was the only carotenoid source that had a signi¢cant e¡ect on skin hue, promoting a reddish coloration to the dorsal skin area and a ventral hue similar to wild red porgy. No apparent e¡ect of carotenoid source on skin melanin content was observed. In contrast, dietary protein/ carbohydrate ratio a¡ected melanin content in the skin. The ¢sh fed the 50/23 diet showed signi¢cantly higher values. Farmed red porgy had eight times higher dorsal-skin melanin content than wild ones.

“…Astaxanthin, a xanthophyll and ketocar otenoid, is the major car otenoid in r ed aquatic animals such as cr ustaceans (Katsuyama et al, 1987;Weedon, 1971;Tor r issen et al, 1989;Chen and Meyer s, 1982;Yamaguchi et al, 1983 and1986;Simpson et al, 1981;Saito and Regier , 1971). Astaxanthin may be used in the cosmetic, phar maceutical, and food/feed industr ies as a natur al color ant instead of synthesized or ar tificial color s. Ther e is a high demand for this pigment in the diets of aquacultur ed salmon and other species as it incr eases their value in the mar ketplace (Simpson and Haar d, 1985).…”

Astaxanthin is an impor tant pigment in fish and shellfish aquacultur e and incr eases the mar ket value of fish such as salmon and tr out. Commer cially synthesized astaxanthin costs about $1,000/kg. Car otenoids have been extr acted fr om cr ustacean wastes with or ganic solvents, but in many of the methods the pigments ar e degr aded.Astaxanthin extr action yield fr om cr awfish tail shells by supercr itical CO 2 was optimized for temper atur e, pr essur e, and moistur e. The cosolvent ethanol (10% w) incr eased yield significantly. Temper atur e, pr essur e, and moistur e content wer e other impor tant independent var iables. These wer e studied using an incomplete 3 3 factor ial (Box-Behnken) design. The equation of the model fitted to the data was extr acted astaxanthin (mg/kg dr y shell) = Ϫ169.3 + 5.36 T + 0.061 P + 7.32 M Ϫ 0.0003 T P Ϫ 0.10 T M + 0.0003 M P Ϫ 0.02 T 2 Ϫ 0.000006 P 2 Ϫ 0.033M 2 , wher e T = temper atur e (EC); P = pressur e (psi); M = moistur e (% ). The maxima for moistur e, pr essur e, and temper atur e wer e 13% , 24 MPa, and 75EC, r espectively. [Article copies available for a fee from The Haworth Document Delivery Service: 1

“…In the trout, the (3S, 3'S)-astaxanthin leads to (3R, 3'R)-zeaxanthin. These data indicate that the epimerization from 3S-to 3R-and vice versa occurs in vivo (Katsuyama et al, 1987). No significant in vivo E/Z isomerization has been observed (Schiedt et al, 1981;Osterlie et al, 1999).…”
