With the latest developments in RAS technology, RAS is entering a new era in the supply of high quality sea food produce.
As in certain open water areas where fish are farmed, fish cultured in RAS can acquire off-flavors from bioaccumulation of Geosmins and MIB’s, which are produced by certain bacteria that can be present in RAS. These bacteria are favored by sludge laden environments and first line of defense is avoiding any sludge entrapment/accumulation in a RAS. So, the extent of off-flavor will to a large extent depend on RAS concept.
The IAA RAS concept has no solids or sludge entrapment/accumulation, but whilst this may not eliminate production of Geosmins and MIB’s, it will minimize purging requirements and purging time.
IAA supply stand-alone purging systems which are combined with harvesting facilities.
