“…In line with this, differences in digestive enzyme gene expression were observed in pike-perch larvae given different diets [34]. In addition, our group has demonstrated an improvement of the condition of pike-perch juveniles subjected to very early weaning (at the start of exogenous feeding) in comparison to fish weaned at the late larval phase [7].…”

“…Though the costs associated with RAS are significantly higher in comparison to pond rearing, novel eco-friendly techniques for disease control, such as probiotics, can be costeffectively applied in the RAS. Probiotics applied very early during larval development could offer additional advantages related to nutrient utilization efficacy, which could boost fish growth beyond the levels offered by the RAS itself [7,27,51]. Survival and performance of RAS-reared fish can additionally be improved by the usage of different live foods (e.g., rotifers) as well as the enrichment of live food with polyunsaturated acids or vitamins [16,28,52].…”

“…However, with the exception of several Western European farms, current pike-perch production is principally performed outdoors, particularly in the larval stages, because of the high mortality and costs associated with RAS larviculture [5]. There are numerous research data describing the two larval rearing technologies for this species-intensive culture exclusively [6][7][8] and extensive pond nursing followed by dry feed habituation in intensive conditions [9][10][11]. Continuous supply of the grow-out material continues to be the main reason for production stagnation in the latter rearing technique [12][13][14].…”

“…Continuous supply of the grow-out material continues to be the main reason for production stagnation in the latter rearing technique [12][13][14]. Therefore, technological development in RAS larviculture is an ongoing issue from the perspectives of nutrition [7,15,16] and technological solutions [4,8].…”

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.

Ensuring the availability of high-quality larvae in sufficient quantities remains a significant bottleneck for the grow-out phase of aquaculture. Over the past century, various alternative dietary solutions for larval stages have been explored, encompassing bacteria, microalgal pastes, yeasts, and various inert microparticles, though with inconsistent outcomes. This review aimed to discuss the innovative integration of probiotics into microfeeds, highlighting encapsulation, coating, and fermentation techniques to propel aquaculture productivity. Microfeeds, which are often nutrient-rich and easily assimilated in powdered or liquid form, play a crucial role in larval fish nutrition. These can be classified into microencapsulated, dry, liquid, and live feeds. The choice of microfeed is pivotal, ensuring appeal, digestibility, and water stability tailored to each larval stage. As probiotics gain popularity in aquaculture for their potential to enhance growth, bolster disease resistance, and improve water quality, their administration methods have diversified. The probiotics can be administered through direct immersion and bath treatments to biofloc systems and feed additives. The results indicated that microfeed incorporated with probiotics showed a positive result impact on the aquaculture industry.
