Seasalter Shellfish continuous algae systems used all over the world, mainly by shellfish hatcheries, have seen some new applications recently with the introduction of rotifer culture. (Species illustrated Brachionus plicatillis).

Rotifers are cultivated in an open flow system. In fact the flow is just neat algae culture. As the algae system uses only pasteurized water the rotifer cultures are free of any harmful contamination such as vibrios, viruses or ciliates. A typical rotifer culture will reach a density of 1500 to 2000 rotifers per ml. Everyday 50% of the volume of the culture can be harvested. The following day as the culture has reach its overflow level, the density is back to its normal level and the process can be repeated indefinitely. With the shortage of Artemia availability worldwide, high quality algae and rotifer production seems to be the obvious answer. more
