Abstract (EN): A 21 day feeding trial was carried out at 24 degrees C aiming to evaluate the effect of diets containing high levels of protein hydrolysates on growth, survival and body composition of common carp, Cyprinus carpio L., larvae since first feeding. Eight semipurified diets based on a fish protein hydrolysate (CPSP) with or without additional nitrogen sources, such as casein, casein hydrolysates or other hydrolysates from several origins, were tested, using a diet based on yeast as a reference. High survival rates of larvae were observed at the end of the trial for all experimental diets, ranging from 97% for the yeast diet to 71% when CPSP was used as the only nitrogen source. In terms of growth, the best results were achieved with the CPSP-casein diet (1:1) and the yeast-based diet (17.5 mm total length / 82.8 mg wet weight and 16.3 mm total length / 55.4 mg wet weight, respectively). Growth of larvae fed on diets with protein hydrolysates as the only nitrogen source was considerably lower than that of larvae fed a mixture of intact protein and protein hydrolysates.
