A total of 398 specimens of 14 cyprinid species were examined for the presence of renal sphaerospores and Sphaerospora blood stages (C blood protozoa). Sphaerospora infection of the kidney was demonstrated in 122 fish of 12 species, and blood stages were found in the blood of 30 fish of 6 species. Blood stages only occurred in f.ish infected by renal sphaerospores and were primarily demonstrabl...

Studies of fishway performance, at the multi-species level in large rivers, are scarce and this raises question passage success both endemic exotic species anthropised environments. The study was conducted downstream part River Meuse (average annual discharge = 400 m3.s-1) on a 13 km transect between two successive fishways (M0 M1). From 2015–2021, total 1065 adult individuals, representing 14 ...
