 note = {The carotenoids in mysis and the internal organs of squid were extracted, purified on the columns, characterized by absorption spectra, the behavior on the columns, absorption maxima of the reduction and co-chromatography with authentic samples. In the mysis, the existence of β-carotene, echinenone, isocryptoxanthin, lutein, zeaxanthin, canthaxanthin, astaxanthin, and crustaxanthin was confirmed. In the internal organs of squid, astaxanthin was found. The content of astaxanthin was most abundant amoung each pigment in mysis and the internal organs of squid. It was clarified that mysis and internal organs of squid were good additives to the food for sea bream in order to improve their reddish brightness. It was assumed that in mysis β-carotene would be converted to astaxanthin through the steps of isocryptoxanthin, echinenone, and canthaxanthin.},
