Two 112-day feeding trials were conducted to examine the effects of including camelina (Camelina sativa) products in rainbow trout diets. In the first experiment, 20 tanks (40. L) of rainbow trout (Oncorhynchus mykiss; 2.36. ±. 0.18. g, 30 fish/tank) were fed one of five diets containing solvent-extracted camelina meal (SECM) at dietary inclusion levels of 0, 50, 100, 150 or 200. g/kg. Weight gain and specific growth rate (SGR) of fish fed 200. g/kg SECM were significantly lower than those fed 0 and 50. g/kg SECM. The protein efficiency ratio (PER) of fish fed 50. g/kg SECM (2.4) was significantly higher than fish fed 0, 150 and 200. g/kg SECM (all 2.1). There were no significant differences among treatments for total feed consumption or FCR, although during earlier periods of the trial, fish fed 150 and 200. g/kg SECM had higher FCR than fish fed 0 and 50. g/kg SECM (P<. 0.05). In the second experiment, 24 tanks (40. L) of rainbow trout (1.0. ±. 0.1. g, 30 fish/tank) were fed one of eight diets: a control diet; six diets containing full-fat camelina seed or high oil residue camelina meal (HORM), at dietary inclusion levels of 100, 200 and 300. g/kg; or a diet that contained 100. g/kg SECM and 151. g/kg camelina oil (SECM. +. CO), with no added fish oil. After 112. days on feed, fish fed diet containing 300. g/kg camelina seed and 300. g/kg HORM gained less weight than fish fed the control diet (P<. 0.05). Fish that consumed 300. g/kg camelina seed also gained significantly less weight than fish fed 100. g/kg camelina seed and 100. g/kg HORM. Feed consumption was not affected by diet. FCR was higher in fish fed 300. g/kg HORM than in fish fed 100. g/kg camelina seed and the PER of the fish fed 300. g/kg HORM was lower than that of fish fed 100. g/kg camelina seed and HORM (P<. 0.05). There was no treatment effect on the intestinal histology of fish fed these diets (P<. 0.05). Fish fed up to 100. g/kg SECM, camelina seed and HORM, as well as the SECM. +. CO diet did not perform any differently than fish fed the control diet (P>. 0.05). Although there were a few negative effects on performance in fish fed 200. g/kg camelina seed and HORM early in the trial, this did not remain consistent for the entire trial. The maximum dietary inclusion threshold of these camelina products in juvenile rainbow trout diets is likely between 100 and 200. g/kg, although further research will be required to determine more definite values. Statement of relevance: This study determines the feed intake and growth response of rainbow trout fed camelina seed (dietary inclusion levels of 0, 100, 200 and 300. g/kg), high oil residue camelina meal (dietary inclusion levels of 0, 100, 200 and 300. g/kg) and solvent-extracted camelina meal (dietary inclusion levels of 0, 50, 100, 150 and 200. g/kg) and a combination of 100. g/kg solvent-extracted camelina meal and 151. g/kg camelina oil, as well as information regarding the carcass composition and intestinal morphology of fish fed the first two ingredients. This research provides data that will enable the formulation of practical diets using these feed ingredients.
