- Abstract:
- ... Although egg de-adhesion has been the subject of research in pikeperch of late, the possible effect of this technological procedure on larval viability under intensive rearing conditions has not yet been evaluated. The aim of the present study was to evaluate the effect of the Alcalase enzyme on egg incubation and larviculture success compared to a commonly used procedure with milk and kaolin clay ...

- 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 ...

Three separate experimental rearings (in 50-L tanks) were conducted, where (1) water temperature (12 days, 3000 ind./tank; 15, 20, and 25 °C), (2) water hardness (12 days, 4600 ind./tank; 15 °C; and 5, 10, an ...

- 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 ...

Growth rates of fish are species- and life stage–specific. Detailed knowledge on the growth rates of the reared species is thus indispensable. Commercial culture of pikeperch (Sander lucioperca) in RAS has been growing for the last dec ...

Eurasian perch (Perca fluviatilis) were sampled in April, from May to June and at the end of August to test whether the current season (i.e. feeding conditions) affects the fishes’ stomach size (i.e. volume and weight). A wide range of size data were analysed to reveal the relationship between fish size (length and weight) and stomach size. No significant differences in length-specific stomach vol ...

- Abstract:

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 ...
