The aim of this study was to examine the effects ozonation on water quality, and growth, blood biochemistry, antioxidant capacity survival pikeperch (Sander lucioperca) reared in a recirculation aquaculture system for 30 weeks. A group without ozone treatment used as control. application led significant reduction chemical oxygen demand, biological demand unsuspended solids concentration. result...

The pike-perch iridovirus (PPIV) was isolated in Finland from apparently healthy pike-perch fingerlings during routine disease surveillance. Our phylogenomic analysis revealed that PPIV is the first fish member of a clade of ranaviruses previously described from European and Chinese amphibians.

The current study evaluated effects of dietary administration doses of Entrococcus faecium on the hematological factors, and disease resistance of Sander lucioperca against Aeromonas hydrophila infection. Fish were fed with dietary administration containing E. faecium doses including of (1010, 108CFU/ g) for diet A1 and A2, respectively in a commercial diet as basal diet were used for 6 weeks. ...

The density and mean size of 0 + pikeperch (Sander lucioperca) were studied in late summer 2004–2017 clay-turbid eutrophic Lake Tuusulanjärvi southern Finland. Hydroacoustics simultaneous experimental trawling used to estimate the pikeperch. In some autumns, was most abundant species pelagic fish assemblage. However, annual amplitude extremely high (1,300 - 19,900 individuals ha−1). variations ...
