- Abstract
The succes of artificial reproduction in the rainbow trout (Oncorhynchus mykiss), the development of gonads and the results obtained at incubation are significantly affected by the feeding of the breeders. The use of quality sexual products is decisive for the assurance of the production of viable larvae and further more estimated fish production, so that in addition to the assurance of optimal environmental parameters, the proper feeding of the breeders is required. Starting from the current stage of knowledge in the field, the main objective of the working paper was to highlight the way that differentiated feeding of the rainbow trout females (Oncorhynchus mykiss) influences their growth and development. Also, have been followed the effects of the extruded granulated feed with a high protein level on egg weight and the gonosomatic index. The results obtained were structured according to the administrated feed and the age of the females, in identical growing conditions. The body development and performance of breeding obtained in rainbow trout females (Oncorhynchus mykiss) were significantly influenced by the quality of the administered feed. The extruded peeled feed with 53% protein proved to be highly effective, materialized trough high growth performances, a better conversion and the growth of gonadal weight.
