Using binders for feed producing needed for aquaculture

Abstract

The article is dedicated to binders, which are used as components of aquaculture feeds. It includes generalization results of modern scientific-applied stuff, mostly obtained by foreign researches, since this kind of information presented at domestic specialized journals in extremely small volume. An information about functional purpose for main feed components — protein- and oil-containing, antioxidants and some others — was presented. Binders impaction on aquatic feed attraction and it’s nutritional value was shown, general functional purposes for binding agents also explained. A small analytical description for Russian binder market presented, a modern classification for binders also was shown as well as main segments in feed market where these binders can be used. Differences in rheological characteristics of various binders and it’s interaction mechanism with feed components within granules are described. Significant differences between Russian and foreign methodologies, used for researching of structurally-mechanical characteristics of feed pellets, are indicated and needs in domestic and foreign analytical techniques harmonization was justified. This article includes results of foreign investigations, dedicated of binders applied using (such as starches, obtained from various raw sources, carrageenan, CMC, pectin, agar, gelatin and so on) while pelleted and extruded feeds production was summarized. Crayfishes, shrimps, sea urchins and fishes (gibel carp, olive flounder) were used for researching and were fed by feeds with these binders. The best kinds of binders and it’s most effective concentrations for feeds, used for various species was defined, impaction on fish farming efficiency also was studied for some of these binders. Needs for further researching works with binders for using in feed production industry was justified.
