“…In such cases, all the environmental factors, conditioning the overall performance of fish, are entirely artificial (Fontaine, Wang, & Hermelink, 2015). This is the case, for instance, in pikeperch production, which relies mostly on the fish intensively cultured in RAS (Steenfeldt et al, 2015). Despite huge progress in intensification of its aquaculture technology over the last two decades, captive broodstock of pikeperch are still characterized by highly variable and/or lowered spawning performance, reflected mainly in poor egg quality (Schaefer, Overton, & Wuertz, 2016; Żarski et al, 2019).…”

Pikeperch, Sander lucioperca, is a species of high interest to the aquaculture. The expansion of its production can only be achieved by furthering domestication level. However, the mechanisms driving the domestication process in finfishes are poorly understood. Transcriptome profiling of eggs was found to be a useful tool allowing understanding of the domestication process in teleosts. In this study, using next

“…Pikeperch Sander lucioperca (L. 1758) is a freshwater species that is an important cultivated fish of great economic interest (Steenfeldt et al, 2015). Sander lucioperca is an apex predator (in terms of ecosystems and fisheries) in many brackish water ecosystems in northern Europe (Hempel et al, 2016).…”

This study characterized the gastrointestinal microbiome of nine juvenile farmed pikeperch Sander lucioperca using a metagenomics approach based on bacterial 16S rRNA gene sequencing. Potential changes in the gut microbiota during 2 months of S. lucioperca juvenile life were investigated. Results revealed that gut microbiota was dominated by Proteobacteria (95-92%), while other phyla Firmicutes (1-1·5%) and Actinobacteria (0·9-1·5%) were less abundant. At the family level, fish-gut microbiota were dominated by Enterobacteriaceae, which constituted c. 83% of all DNA sequence reads. Such a situation was present in all of the examined fish except one, which showed a different proportion of particular microbial taxa than the other fish. In this fish, a higher relative abundance (%) of Fusobacteria (21·0%), Bacteroidetes (9·5%) and Firmicutes (7·5%) was observed. There were no significant differences in the gut microbiome structure at different stages of development in the examined fish. This may indicate that Proteobacteria inhabiting the gut microbiota at an early stage of life are a necessary component of the pikeperch microbiome that may support proper nutrition of the fish. The information obtained on the gut microbiome could be useful in determining juvenile S. lucioperca health and improving rearing conditions by welfare monitoring in aquaculture.

“…Because of the high demand, pikeperch is currently one of the targeted species included in the European Union's plans to diversify the inland freshwater aquaculture. However, larviculture development in recirculating aquaculture systems (RAS) are encountering several obstacles such as low stress resistance, nutritional deficiencies, and cannibalism which result in low survival rates during the larval stage [3]. In order to supply the larvae with adequate nutrition, live feed is required.…”

Use of Lactic Acid Bacteria During Pikeperch (Sander lucioperca) Larval Rearing

This trial tested the use of lactic acid bacteria (LAB) on pikeperch (Sander lucioperca) larvae during their first feeding. The trial included the use of two probiotic treatments and one control (no probiotics). Pikeperch larvae were exposed to LAB as follows: (1) the live feed (Treatment 1, live feed) or (2) via the live feed and the larval rearing water (Treatment 2, probiotic). Significant differences were found between the treatments in terms of total length (TL), myomere height (MH), overall survival, and the tolerance to a high salinity challenge. Larvae exposed to LAB via both the live feed and the rearing water had a significantly higher overall survival rate (85%) than the other two treatments at 21 dph. When both treatments were subjected to high salinity rates (18 parts per thousand (ppt)), both treatments exposed to LAB demonstrated higher survival rates than the control treatment (28% and 40% survival rate at 180 min for the live feed and probiotic treatments, respectively, as compared with a 100% mortality rate at 150 min for the control). At the same time, larvae exposed to the probiotic treatment had a significantly higher TL as compared to the control after 12 and 21 days post hatch (dph) (probiotic 7.13 ± 0.21 and 11.71 ± 1.1 mm, control 5.86 and 10.79 mm at 12 and 21 dph, respectively). The results suggest that the use of LAB in both the live feed and the rearing water has a positive effect on pikeperch larval quality by strengthening their resilience to stress conditions, as well as improving the growth and survival rates.
