Abstract:
... Pikeperch (Sander lucioperca) is a native fish species in the European and Asian basin, representing high natural and economical value. However, our information on the genetic background and diversity of European populations is still limited, despite of that the production and the number of bread stocks has increased significantly in the last decade. Our aim was to develop new useable species-spec ...

Abstract:
... Fish embryos and larvae undoubtedly depend on maternal provisioning of essential egg components, such as fatty acids (FA), during early ontogeny. But which aspects and stages of batch-specific larval development are modulated by these inherent oocyte traits? This question is of major importance from an ecological, as well as from an aquacultural perspective. We examined the effects of batch-specif ...

Abstract:
... With the development of recirculating aquaculture systems (RAS), fish species, like European perch (Perca fluviatilis), can be produced efficiently. The lack of experience in the cultivation and emerging pathogens of this species often lead to high mortality during the production cycle. In this study, we evaluated diagnostic submissions of European perch from a warm water RAS analyzed at the Centr ...

High mortality (88.9–91.4%) of pond-cultured pikeperch Sander lucioperca broodstock was found 10 days post-spawning primarily due to body injury (15.2–18.2% of body area) and secondary fungal infection (27.6–34.8% of body area). Ninety days post-spawning mortality was 97.1–98.1%. Surviving broodstock showed satisfactory condition with no observable pathology. Thirty-six treatments were evaluated f ...

Abstract:
... Larval rearing is a crucial step in fish production. However, issues in larval production, such as low growth/survival rate, impede the aquaculture development of many species including Perca fluviatilis. Since allopatric populations of P. fluviatilis exhibit different growth rates for first-life stages, basing fish stocks on populations displaying optimal features in aquaculture conditions could ...
