Hazelnut meal as a substitute for soybean meal in extruded feeds of rainbow trout was investigated. The performance of extruded feeds containing hazelnut meal as a substitute for 20% of soybean meal (Diet 2) and 30% of soybean meal (Diet 3) was compared to a nutritionally balanced control (Diet 1) (a commercial trout feed formulation). Each diet was fed to 3 replicate groups (initial BW: 36 ± 1.37 g; mean ± SD); the fish were fed the equivalent of 2% of their body weight, 2 times daily (0800 and 1600) for 64 days at 15 ± 0.11 °C under a …

The effects of diets including various natural carotenoid sources and synthetic astaxanthin on the pigmentation and growth of rainbow trout (Oncorhynchus mykiss) were investigated. Rainbow trout weighing about 111 g were fed diets containing 1.6%, 2.4% and 3.2% marigold flower; 4.4%, 6.6% and 8.8% red pepper; 100 mg kg^{-1} synthetic astaxanthin; and a control diet for 60 days. At the end of the experiment, synthetic astaxanthin provided the highest carotenoid accumulation in the fish flesh (6.42 mg kg^{-1}) in the groups. This was followed by red pepper (5.78 mg kg^{-1}) and marigold flower (5.59 mg kg^{-1}), each of which included …
