The effect of dietary lipids on reproductive performance in rainbow trout (Oncorhynchus mykiss)
Main Article Content
Abstract
The present study evaluated the effect of different dietary lipids on the reproductive performance of rainbow trout (Oncorhynchus mykiss). Brood fish (approximately 920 g, n = 80) were fed four different diets containing the same amount of protein and lipid. The lipid sources used in the diets were fish oil (FO), linseed oil (LO), soybean oil (SO), and a commercial trout diet (CTD), which were fed for seven weeks before spawning.
The growth rate of fish in the different treatment groups did not differ during the experimental period. The mean diameter, volume, and weight of the eggs also did not differ among treatment groups. Absolute fecundity, relative fecundity, and gonadosomatic index were not affected by the diets. The results showed that linseed oil and soybean oil can be used as lipid sources in the diet of rainbow trout broodstock without reducing egg quality or reproductive performance.
