Growth Performance and Egg Ratio of a Marine RotiferBrachionus rotundiformisFed Different Diets in Captivity

Original language description

This study was carried out to evaluate the population growth and egg ratio ofBrachionus rotundiformisby feeding with three different diets, i.e., live microalgaeNannochloropsissp., Baker&apos;s yeast, and powderedspirulina. A total of nine conical flasks of 1 L volume were divided into three treatment groups for determining the feeding performance for eight consecutive days. Each experimental group was stocked withB. rotundiformisat an initial density of 10 ind. mL(-1). Water temperature, pH, salinity, and light were maintained at (24-29) degrees C, (7.5-8.5), 30 ppt, and 4000 lx, respectively. Feed was provided twice per day at 9:00 AM and 7:00 PM. The highest mean (+/- SE) population growth of rotifer was achieved at the end of the culture period (on the 8th day) fed liveNannochloropsissp. (122 +/- 12 ind. mL(-1)), which was significantly higher compared to the Baker&apos;s yeast and powderedspirulina(p &lt; 0.05). The mean egg ratio ofB. rotundiformisfed three diets was significantly differ at different rearing periods (p &gt; 0.05). The highest mean (+/- SE) egg ratio ofB. rotundiformiswas observed in the liveNannochloropsisfed group (0.89 +/- 0.01) at the end of the rearing period, which was significantly higher than that of Baker&apos;s Yeast and powderedSpirulinafed group (p &lt; 0.05). Among the three diets, liveNannochloropsishad shown the dietary superiority over Baker&apos;s yeast and powderedspirulinain culturingB. rotundiformis. The results of this study suggest that liveNannochloropsiscould be the most suitable diet for the laboratory culture ofB. rotundiformis.
