Effect of purified carotenoids added to compound diets on pigmentation of Penaeus japonicus (Crustacea, Decapoda). Abrill, Marco Otazu; Ceccaldi, Hubert J. (Stn. Mar. Endoume, Ec. Pratique Hautes Etud., Marseille F-13007, Fr.). Aquaculture, 36(3), 217-28 (French) 1984. CODEN: AQCLAL. ISSN: 0044-8486. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Penaeid shrimp were fed a compd. diet contg. various ratios of carotenoid pigments as carophyll red (I) [514-78-3] (0.1, 0.5, 2.5 and 10 g/kg) and canthaxanthin (II) [514-78-3] (0.01, 0.05, 0.25 and 1.25 g/kg). Their accumulation in the epiderm-hypoderm complex, in the hepatopancreas, and in the exuviae was measured by thin-layer chromatog. and spectrophotometry. Carotenoid accumulations in epiderm-hypoderm complex are, whatever their concn. in the diet, close to 23 mg/g using I and 26 mg/g using II>. Slightly higher values are obsd. with 0.1 g I/kg and with 0.01 g II/kg. For the hepatopancreas, maximal accumulations were obtained with diets contg. 10 g I/kg and 0.01 g II/kg. For the exuviae, max. accumulations were obtained with diets contg. 0.5 g I/kg and 0.05 g II/kg. Extd. pigments were roughly 50% astaxanthin [472-61-7] and 30% echinenone [432-68-8]. The concns. of these 2 pigments varied inversely with each other.Except for chemicals metioned above, 472-61-7 and 12738-95-3 are also used. .

These chemicals are also mentioned in this article.; Bermond, P.; Santamaria, L. (Inst. Pharmacol. II, Univ. Pavia, Pavia, Italy). Med., Biol., Environ., 10(3), 25-31 (English) 1982. CODEN: MBENDX. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Section cross-reference(s): 1 Skin tumors induced in mice by benzo(a)pyrene [50-32-8] and UV light were partially inhibited by feeding b-carotene [7235-40-7] or canthaxanthin [514-78-3]. Mechanisms for such tumor inhibition are discussed. .
