Adaptation of Intensively Reared Pikeperch (Sander Lucioperca) Juveniles to Pond Culture and Subsequent Re-Adaptation to a Recirculation Aquaculture System

Popis výsledku v původním jazyce

A combination of intensive rearing and pond culture was evaluated on its benefits for pikeperch year-round production. Fifteen hundred intensively reared juveniles (group IRJ) and 1500 pond-reared juvenile pikeperch as a control (group C) were divided into three batches and stocked into three ponds for 178-day long culture. Survival of fish in group IRJ was significantly higher (65.2 +/- 15.9%) compared to group C (47.3 +/- 1.6%) (P<0.05). SGR (group IRJ = 0.018 +/- 0.012%. d-1; group C = 0.014 +/- 0.027%. d-1) and Fulton coefficient (FC for group IRJ = 1.02 +/- 0.13; FC for group C = 0.95 +/- 0.57) did not differ at the end of pond culture which included winter and spring seasons. After harvesting, fish from group IRJ were transferred to a recirculation aquaculture system and after a short adaptation period, they were fed with pellet feed. The duration of following intensive rearing in the RAS lasted 46 days. SGR was 0.732 +/- 0.441%. d-1, FCR = 2.1 +/- 1.2, FC = 1.20 +/- 0.09 and survival rate was 98.4 +/- 0.9% at the end of the 46-day rearing period. No difficulties were observed in adaptation of intensively cultured juveniles to pond conditions. During the study, it was obtained a high survival rate and excellent ability of pikeperch juveniles to consume dry feed after their re-adaptation to recirculation aquaculture system.
