Correlations among the Main Body Measurements in Pikeperch Larvae from 10 to 25 Days Post-Hatch, Obtained Out-Of-Season

Abstract

The pikeperch (Sander lucioperca) is one of the most valuable carnivorous fish species in Europe, and in Romania as well. In the literature there are no relevant data on growth dynamic and correlation among the main body measurements in pikeperch larvae obtained out-of-season and reared in recirculated aquaculture system (RAS). The aim of this study was to bring information for clarifying some of these aspects. Our results emphasized that correlation coefficient between maximum body high (H) and total length (TL) together with standard length (SL) decrease linear from 10 to 25 DPH. The correlation coefficients between the main length measurements (TL and SL) reveal a very high correlation between the two traits in pikeperch larvae. High correlations between body weight (BW) and the other length measurements were observed.
