Two trials were conducted to determine the effect of dietary inclusion of camelina ( Camelina sativa ) products on their digestible nutrient compositions in rainbow trout. In the first experiment, the following camelina products: full‐fat seed, oil, high‐oil residue meal ( HORM ), pre‐press solvent‐extracted meal ( SECM ) and toasted SECM were evaluated. In the second trial, the utilization of SECM , SECM soaked in water ( WS ), SECM treated with a multicarbohydrase, Superzyme™‐ OM , SECM treated with Bio‐Phytase and SECM treated with Superzyme™‐ OM and Bio‐Phytase ( MIX ) was determined. The experimental diets consisted of a basal diet and test ingredient with a ratio of 70:30, except for camelina oil where the ratio was 80:20. In Experiment 1, SECM had the highest level of digestible crude protein (352 g kg −1 ), whereas the oil was the best source of digestible energy (8,063 kcal kg −1 ) and digestible crude fat (908 g kg −1 ). In Experiment 2, there were no significant differences in nutrient digestibility of SECM and HORM ; however, WS and MIX had significantly more digestible dry matter and digestible crude fat than SECM and HORM . Camelina by‐products have the potential to replace fishery by‐products in rainbow trout feeds.
