ResumoTechniques are described for the culture of the larvae of Palaemon serratus Pennant to the post-larval stage on a diet of Artemia salina L. from the Great Salt lakes, Utah. Previous attempts to rear the larvae of certain marine Crustacea and fish on this diet have failed, although stocks of A. salina from salt pans near San Francisco are usually a satisfactory food. The value of a diet of Utah Artemia to a variety of species is reviewed. The addition of the alga Isochrysis galbana Parke to cultures of Palaemon serratus larvae and Artemia nauplii allowed complete development of the larvae to the post-larval stage. Utah Artemia nauplii fed with Isochrysis before they were given to the larvae were also satisfactory, but newly-hatched nauplii as well as nauplii that had been starved for 24 h were not. It is shown that Palaemon serratus larvae can be reared on a diet of newly-hatched Utah Artemia nauplii for approximately the first 12 days of life with no adverse effects, provided that the diet is then changed to Artemia from San Francisco or small, partially-grown Artemia. Artemia eggs and nauplii from San Francisco and Utah were analysed for the presence of pesticides, heavy metals, carotenoids, sterols, and fatty acids. Some differences were found but none of them could be confidently labelled as the cause of the poor food value of the Utah Artemia nauplii.
