Population growth and cyst production of the rotifer Brachionus plicatilis (Monogonta: Brachionidae) fed with three different diets
This study compares the effect of different diets on population growth, fecundity rate, production, and cyst hatching efficiency of the rotifer Brachionus plicatilis . Microalgae were cultured using filtered and steril - ized seawater at 25 and 26°C. The volume of the containers for algae, bread yea...

| Sumario: | This study compares the effect of different diets on population growth, fecundity rate, production, and cyst hatching efficiency of the rotifer Brachionus plicatilis . Microalgae were cultured using filtered and steril - ized seawater at 25 and 26°C. The volume of the containers for algae, bread yeast, and rotifer was duplicated daily from 31mL to 16L in nine days. Rotifers were cultured at 25°C and 35% salinity. The mean values of daily population growth rate for the rotifers fed on C. muelleri , I. galbana and bread yeast were 0,91, 0,89 and 0,87 daily counts, respectively. Af - ter 10 cultured days, fecundity was 72%, 63% and 36% using C. muelleri , I. galbana and bread yeast, respectively. The highest mean value for cysts production was 4 064 000 cysts found from 63 243 (1,55%) rotifers fed on C. muelleri . Hatching efficiency after 36 hours of cysts from rotifers fed C. muelleri was 51 500 (94,3%) new borns, followed by 45 000 (93,3%) with I. galbana , and 31 000 (92,6%) with bread yeast. C. muelleri is a good food source for B. plicatilis. |
