Abstract:

Four types of frozen adult Artemia biomass (regular and enriched (with HUFAs and other nutritional supplements) San Francisco Bay and Canadian brands), and frozen hard clam (Mercenaria mercenaria) were evaluated as broodstock diet for the marine ornamental shrimp Lysmata wurdemanni. There is no significant difference among the five diet treatments in fecundity (number of eggs produced), relative fecundity (number of eggs/g female), egg dry weight, egg percent ash, and total length of newly hatched larvae. Egg volume was significantly larger in the San Francisco Bay regular treatment than those of other treatments. Survivorship from zoea 1 to zoea 2 was higher in the San Francisco regular, Canada enriched, and hard clam treatments.
