The effect of the feed additive «Kormogran selen-3» on fish breeding, morphometric indicators and marketable qualities of Rainbow trout

An experimental cultivation of rainbow trout was carried out using the selenium-containing feed additive «Kormogran Selen-3». According to a number morphometric parameters, there were no significant true differences between and control groups, however, an intensification fat metabolism in group established, which slowed down process accumulation intracavitary by individuals. This caused some lag total mass decrease fish-breeding biological indicators. At same time, rate linear growth overall development fish. The main selenium occurred liver, where its content increased 613,9 times (from 1112 15363 μg/kg). this element white muscles 5,2 times, red – 2 indicates possibility intravital enrichment muscle tissue with selenium. analysis quality commercial fish nutritional value showed advantages batch comparison yield edible parts, organoleptic evaluation smoked products, at time can be attributed functional product as source
