Abstract A study was conducted to assess effects of four diets on reproduction by the mysid Mysidopsis bahia in routine culture conditions. Two experiments were performed: the first lasted 25 d under semistatic conditions and the second lasted 60 d under flow-through conditions. The objective was to determine which nutritional options, including supplementation of the normal diet of brine shrimp (Artemia spp.) with other live food (rotifers) or with an artificial Artemia spp.-enrichment product, AEP (Selco), most effectively increased growth and reproduction of the mysids. Diet treatments included reference artemia nauplii as a control; artemia nauplii with no detectable long-chain highly unsaturated fatty acids; the latter artemia diet enriched with AEP; and reference artemia plus live rotifers (Brachionus plicatilis). Mysids fed AEP-enriched artemia had significantly higher percentages of females with eggs developed on days 10, 12, and 13 posthatching than did mysids fed the other diets. Weekly subsamples of population densities showed that the AEP treatments consistently produced larger numbers of young. The results indicated that AEP-enriched artemia were an efficient and cost-effective means of boosting production of mysid cultures. The AEP also was found to be free of contaminants and therefore suitable for culture of toxicological test organisms. (Copyright (c) by the American Fisheries Society 1991.)
