Abstract:
Fabrea salina is a pelagic and hypersaline ciliate having potential to be used as live food source in commercial aquahatcheries. At preliminary level of culture, in different volumes, three different kinds of feeds viz. commercial yeast, Dunaliella and egg-custard were used at different concentrations to examine their efficacy. Besides, after analyzing the effect of salinity, temperature and light on the population growth, mass culture experiments were conducted in up to 300 l water. Compared to yeast and Dunaliella, the maximum population density (90 ciliates/ml) was obtained with egg-custard used at 10 mg/l concentration, whereas with yeast and Dunaliella, the highest density was 50 and 64 Fabrea/ml, respectively, at the corresponding food concentration of 15 mg/l and 6X10*6 algal cells/ml. No significant difference in the population density was observed ( P= 0.05) at varying concentrations of these three feeds. Because of highest population density of 76 cells/ml achieved at 65 per thousand salinity and 70 cells/ml at 28 C, the same salinity and a temperature of 28~1 C were selected in mass culture experiments. A temperature of 36 C resulted in the highest population density, 92 cells/ml, showing the generation period of about 16 h. The culture under continuous illumination resulted in better growth (102 ciliates/ml) when compared with that in complete darkness (76 ciliates/ml). Comparing the results of mass culture at four different levels, i.e. 20, 50, 200, and 300 l, using egg-custard as sole food at 10 mg/l, the maximum population growth (82 ciliates/ml) was achieved in 200 l culture system which was provided with air–water lift recirculatory system.
