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

Popis výsledku v původním jazyce

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.
