    Pigmentos carotenoides del camarón Artemesia longinaris Bate (Crustacea, Decapoda, Penaeidae)
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1984) Carreto, J.I.; Carignan, Mario O.
    Caronetoids from caparace and internal organs of Artemesia longinaris were isolated and identified. The following carotenoid pigments were found in caparace: luteine, tunaxanthin diester, astaxanthin monoester and free astaxanthin. A much greater variety of pigments was isolated from internal organs: Ó- doradexanthin, a fucoxanthin derivate, chlorophylls degradation products and various xanthophylls in trace amounts. These pigments are of dietary origin. In the natural environment, A.longinaris takes preformed astaxanthin from the diet and transfers it to body tissues.
