Investigation of physico-mechanical and chemical properties of compound feeds with deodorization straps for sturgeon fish

Breeding sturgeons in aquaculture is the only way to preserve them as a raw material for fish food products today. In this regard, not need development of commercial sturgeon breeding obvious, but also importance research aimed at studying and developing optimal modes industrial cultivation different species sturgeon. The aim work expand range compound feed sturgeons, expense unused reserves expanding base, which are by-products oil fat industry, particular, deodorization cuts. Based on study classical technology obtaining valuable eliminating its shortcomings, has been developed production pseudo-encapsulated with content more than 20% it vitamins adapted various types grown Central Federal District Russian Federation. proposed species, pseudocapsulation granules absorbers waste, example, cuts, carried out plate granulator. On basis studies performed, was found that order introduce an increased cuts (more 20%) into composition pseudoencapsulated feed, necessary use absorbers, can be recommended silicon dioxide aerosil. When using aerosil, possible ensure inclusion up 20-30% ratio 1:4, without worsening technological properties finished product.
