Abstract

This paper evaluates the eff ects of two diff erent feeds on production results and economic performance in the rainbow trout (Oncorhynchus mykiss) farming. The first group (O-1) was fed with a standard complete pelleted feed, and the second group (O-2) was fed with combined feed consisting of 75 % pellets and 25 % of sardines. Better results were obtained with the O-2 group, while the O-1 group achieved results characteristic for local farming conditions and feed quality. Experimental group O-2 had signifi cantly higher (p<0,01) growth rate when compared to group O-1. Considering current feed and fi nal product (fi sh) prices in the market, better results in terms of cost-eff ectiveness were obtained (E>0,00) in O-2 group of trout fed with the combined meal.

Highlights

Fish production as well as nutrition has developed significantly in recent years (Azis at al., 2011)

Summary

Introduction

Fish production as well as nutrition has developed significantly in recent years (Azis at al., 2011). Nutrition is critical because feeding represents almost half of the production costs. Rainbow trout is one of the most important Salmonide species of major economic interest for commercial culturing worldwide and it is the dominant type of trout farming in the Balkans (Vranić, 2012). The type of feed and the feeding process itself are among the most important factors influencing trout growth, feed utilization and tissue composition in intensive production. Much work has been done to create the optimal nutritional requirements, feeding process, growth and feed conversion ratios of salmonids (Okumus at al., 2002). Much effort has been and is still put into creating feed composition best for developing balanced commercial diets that promote optimal growth and health with minimal production cost
