Introduction of Arctic Char in Aquaculture of Russia


Arctic char has some features making it a promising object for commercial farming. It has relatively good growth rates at low temperatures and can be grown at a high density of stocking. The combined effect of low temperature and oceanic salinity is detrimental to char. We believe that directly in the gulfs and bays of the Barents Sea it is impossible to perform year-round commercial farming in stockings of wild original Arctic char, even taken from lakes that connect a river with the sea. On Murman, the use of recirculating aquaculture system (RAS) may be recommended, especially considering that char tolerates high stocking densities from 40 to 100 kg / m3 during the oxygenation of water. Char can double its weight in just six months while maintaining optimal conditions in a recirculating aquaculture system. It is necessary to install a device in a recirculating aquaculture system that makes fish constantly swim in a circle at a speed of half the length of their body per second. Char is the most valuable fish on the Earth, since it accumulates heavy metals in its tissues to a lesser extent. Apparently, contaminators that enter a body are easily excreted during the fasting period. Taking into account the above-mentioned aspect, Arctic char can be introduced into aquaculture in Russia.
