Abstract

L-Carnitine enrichment has shown considerable influence on the population growth, reproduction and individual growth of rotifer, Brachionus rotundiformis. Rotifers were enriched with 8 levels of L-carnitine supplements dissolved in Nannochloropsis oculata culture medium in a 3 ml-individual culture trial for 10 days, and 5 levels in Chlorella vulgaris culture medium in one l batch culture trial for 5 days. In the batch culture trial, 42, 38 and 50% increase in population densities (P < 0.05) were observed in 1, 10 and 100 mg l -1 treatments, respectively, whereas, the 1000 mg l-1 treatment had a significant decrease in population density (34-45%, P < 0.05) and markedly higher egg ratio (P < 0.05). The 1000 mg l-1 L-carnitine-enriched rotifers obtained significantly smaller body size (P < 0.01), but those enriched with the other 3 levels of L-carnitine (1, 10, 100 mg l-1) showed larger body size. In the individual culture trial, an increasing trend was observed in population density after 5 days and 10 days of culture in 0.001-10 mg l-1 treatments. The results suggest that L-carnitine could be a positive factor to enhance reproduction and population growth on enriched rotifers directly or/and indirectly under the optimum concentration. The lipid metabolism in rotifers may be carnitine-dependent.
