ABSTRACT

The aim of study was to evaluate the effects of the live diet and pellet diet on the survival and growth rates of the stocking material of nase fry. The rearing was performed in two variants: live-fed group (LFG) and pellet-fed group (PFG) – larvae fed on prepared food starter. The LFG were reared on similar food that occurred in a stream designed for the stocking in each week of the experiment (zooplankton, chironomids larvae and periphyton). In the beginning of rearing, the PFG were characterized by higher values of total length, mass than those from the LFG. After supplementation with periphyton for the LFG, the values of total length and mass of the LFG were higher than those of the PFG. Our results show that the rearing of the nase fry on natural food may lead to them obtaining satisfactory growth rates.

Key words: Chondrostoma nasus, Foraging skills, Fish restoration, Fish nutrition.
