Evaluation_of_different_feeding_frequencies_in_RAS-based_juvenile_pikeperch-DATA

Data file for a study examining various feeding strategies for juvenile pikeperch (Sander lucioperca) in a Recirculating Aquaculture System (RAS) over a period of 112 days. It compared five different feeding intervals (2 hours, 4 hours, 6 hours, 8 hours, and 12 hours) using an automatic feeder Imetronic® (Pessac, France). The results showed that shorter feeding intervals led to higher growth heterogeneity and slightly increased fin damage. However, all tested feeding frequencies provided sufficient nutrients for proper pikeperch growth and welfare. The 8-hour feeding interval was identified as optimal, supporting better conditions for fish (Fulton's coefficient), specific growth rate, survival rate, lower fin damage compared to other tested frequencies, and optimal levels of biochemical parameters in blood plasma. ACCESSit is a condition of the CENAKVA RI financing provider to record accesses to open data.
