New technologies and quality of trout and carp aquafeed

SUMMARY The objective of our researches was to examine efficiency of installed extruder and vacuum coater, and benefits of applied technology in trout and carp feed, and to determine physico-chemical composition and nutritional value of this feed in comparison to fish feed made by renowned world producers. The quality fish feed production is a complex technological procedure that requires great knowledge but also an adequate equipment. A satisfactory preparation of raw material, extrusion, as well as, the use of the vacuum coater, are certainly necessary segments in the technological lines for the feed production for such kind of an animal. Obtained production results indicate that feed manufactured in our facility generates same results as the feed of three renowned world feed producers. The results obtained at the end of trial show that floating pellets for carp, particularly in group 1, had somewhat increased performance benefits (growth rate and FCR) as compared to sinking pellets
