Notes
Continuous production of the rotifer Brachionus plicatilis rotundiformis (S-type) in an intensive chemostat culture system has been investigated. The production dynamics of rotifers in relation to different flow rates and feed regimes show that the growth rate and production depends on the type of algal feed and flow rate utilized in the culture system. It was possible to achieve a mean production of up to 318.84x10E6 rotifers m-3 d-1 at a flow rate of 6 L h-1 in 100 L chemostats and up to 261.21x10E6 rotifers m-3 d-1 at a flow rate of 40 L h-1 while using 1 m3 capacity rotifer chemostats as production units. The W3 fatty acid composition of rotifers while using Chlorella and Nannochloropsis in the culture system has been described. The results of this investigation show that the rotifer productivity in the continuous culture system is considerably higher than in any of the conventional culture systems described to date for aquacultural purposes.
