Interpretive Summary:

Technical Abstract: Sunshine bass culture in tanks starts with feeding the fry live rotifers. Production may be increased if the rotifers are enhanced with highly unsaturated fatty acids before being fed to the fry. That procedure involves time, effort and cost. This experiment was done to determine if significant differences in production resulted from the procedure. Sunshine bass fry were cultured from age 4 days to age 12 days in replicated tanks with the following diets: rotifers that had been fed 1) a diluted Nannochloropsis paste and Culture Selco 3000; 2) Nannochloropsis, Culture Selco 3000, and Pavlova, and 3) Nannochloropsis, Culture Selco 3000 and Super Selco. No differences in survival, length, weight, or body condition were found among fry subjected to the treatments. Lack of differences in growth, survival and condition indicates that the first diet which is the least expensive and requires the least amount of effort should be fed to the fry.
