Scientific and production company "AQUATECH" is a new leader in the production of starter feeds for young Pacific salmon

Abstract

We analyzed the feeding efficiency of pink salmon (Oncorhynchus gorbuscha), chum salmon (O. keta), masu salmon (O. masu) and coho salmon (O. kisutch) juveniles at the federal fish hatcheries of Sakhalin during seven fish breeding cycles using starter feeds from «Aller Aqua» (Denmark) and «Aquatech» (Russia). It was established that the feed coefficient when using Russianmade feed was lower at all enterprises and when growing juveniles of each salmon species. In addition to the quality of the feed itself, this may be due to the combined effect of two factors, firstly, with the use of special feeds with biologically active additives to stimulate immunity at the initial stages of feeding, and secondly, with the presentation of feeds in two flotation options «conditionally floating» or slowly sinking and «floating» or floating, as well as the selection by experience for each enterprise of the most suitable option.
