Abstract:

In this study, L-type marine rotifer Brachionus plicatilis were enriched with 10 levels (0, 0.001, 0.01, 0.1, 1, 10, 100, 500, 1000 and 1500 mg L-carnitine per l) of L-carnitine supplements dissolved in marine Chlorella spp. culture medium in 1 L mass culture trial for 7 days. The initial rotifer density was 100 ind ml-1. The trials were conducted 1.5x106 cell ml-1 at food density, at 25±1 ºC under an axenic condition in the laboratory. L-Carnitine enrichment has shown considerable influence on the population growth, reproduction and individual growth of rotifer Brachionus plicatilis. The increase of population density was detected in 0.1-100 mg/l-1 L-carnitine-treated rotifers but the highest population density (P<0.05) was detected 704,50±5,50 ind ml-1. L-carnitine significantly stimulated reproduction of enriched rotifers. The results suggest that L-carnitine could be a positive factor to enhance reproduction and population growth on enriched Brachionus plicatilis.
