Vitamin A and carotenoids in certain invertebrates VI. Crustacea: Penaeidea

Abstract

Vitamin A and carotenoids were measured in six species of Penaeidae and seven species of Sergestidae. Vitamin A was present in at least one sample of all species except Gennadas borealis at concentrations mostly of the same order as previously found in other Decapoda, but usually higher in the Sergestidae than in the Penaeidae. Carotenoids in the Penaeidae included astaxanthin and its esters, carotenes and xanthophylls, but only astaxanthin or its esters with occasional traces of xanthophylls were found in the Sergestidae.
