“…Genetic selection. One of the main stressors encountered by fish larvae reared in the RAS, which is rarely present in ponds, is the failure to inflate the swim bladder [41]. Swim bladder non-inflation remains the main culprit of high mortality during intensive larval rearing [42].…”

This study aimed to estimate the efficacy of two pike-perch juvenile production technologies: exclusive Recirculating Aquaculture System (RAS) culture (the RAS group) and pond larviculture with a transfer to the RAS at the 42nd day post-hatch (DPH). Both direct weaning on dry feed (the Pond-D group) and 10-day gradual weaning using bloodworms (the Pond-B group) after transfer to the RAS were evaluated in pond-nursed fry. Their survival and morphometric indices were monitored after the RAS habituation period (first 10 days), after the 18-day post-habituation period and after an additional 30 days of on-grow. Our results indicate a negative allometric growth of the pond-nursed fish during the nursing period, which was slower (p < 0.0001) in comparison to the RAS-nursed fry (16.3 ± 0.4 vs. 17.8 ± 0.7%/day). After transfer, these fish grew faster than the RAS-nursed fry (7.7 ± 0.1, 4.9 ± 0.5 and 6.1 ± 0.6 during habituation, 8.5 ± 0.6, 9.3 ± 0.5 and 6.7 ± 0.1%/day during post-habituation period, in the Pond-B, Pond-D and RAS groups, respectively). However, four weeks afterwards, the RAS-nursed fry were again superior in terms of growth (4.0 ± 0.1, 3.6 ± 0.2 and 4.6 ± 0.2%/day, for the Pond-B, Pond-D and RAS groups, respectively), and this was accompanied by a significantly lower feed conversion ratio in this group. Although the survival of the RAS-nursed fry during the nursing period was lower in comparison to the pond-reared fry (11.3 vs. 67.3%), the RAS seems to provide a long-term growth advantage.

“…This viscosity can lead to additional difficulties during development also for the young and small pikeperch larvae, causing locomotion to become crucial for survival. Thus, problems of, for example, hydrodynamic starvation during initial feeding events (China & Holzman, 2014) as well as difficulties with breaking through the water surface during swim bladder inflation (Blecha et al, 2019; Summerfelt, 2013) can occur occasionally during early development of pikeperch larvae. Up to now, no study was undertaken to analyse muscle development and its regulation during that time in pikeperch.…”

Pikeperch is a new focus species in freshwater aquaculture. It has large economical potential as it already has a broad consumer base as well as the biological capability to produce large numbers of offspring (Lappalainen et al., 2003;Steenfeldt et al., 2015). Still, it is rare in aquaculture, as high mortality rates occur during its rearing and husbandry (Policar et al., 2019). This is especially severe during the early development between embryonic and larval ontogeny. During this period, the loss of around half or more of the reared specimens can occur, which highly affects the economic success of pikeperch aquaculture (Ostaszewska et al., 2005;Szkudlarek & Zakęś, 2007).Several developmental changes occur during this time including late embryonic organ formation, hatching, the transition from endogenous to exogenous feeding and several organ changes connected to

“…Fazekas et al (2021) reached an SBI of 70% with the help of water jets spraying the surface. Blecha et al (2019) observed 83.4% to 99% SBI in ponds during traditional pond larvae rearing. The higher SBI in pond culture may be explained by optimal nutrition and thus better viability and ability to breach the clean water surface.…”

“…If the surface is covered with slime, lipid residues or other impurities, this issue may become a serious bottleneck due to the irreversibility of the process. Aberrant energy-consuming swimming behaviour causes a higher mortality or deformity rate (Clayton and Summerfelt 2010;Blecha et al 2019). Fish able to breach the water surface are at risk of transferring bacteria from the water surface to the swim bladder.…”
