is a landlocked population restricted to a 270 km stretch of the Kootenai River, which flows from western Montana through northern Idaho and into British Columbia. This population has shown an almost complete lack of natural juvenile recruitment since 1974. The total adult population in 1998 was estimated to be about 650 individuals and this fish is currently classified as endangered by the Ida...

A population of Echinorhynchus baeri Kostylew, 1928 with 18-24 rows of 8-10 proboscis hooks each and long fusiform eggs measuring 95-110 × 18-22 μm collected from Salmo trutta (Salmonidae) in a branch of the Murat River in Turkey is described and specimens are designated as neotype. Specimens of two similar populations of E. baeri (E. baeri Kostylew, 1928 and E. sevani Dinnik, 1932) were previo...

Immersing Siberian sturgeon fry of an average body mass of 40 ± 4 g in epin solution (0.1 mg l -1 ) resulted in an increase of ceruloplasmin level over the entire experimental period (P < 0.001). The differences between the treated and control groups gradually increased reaching the maximum in the fourth and fifth weeks of the study when average levels of ceruloplasmin in the epin-treated group...

The aim of the study was to estimate the effect of culture conditions and culture site on magnesium (Mg) and zinc (Zn) concentrations in freshwater fish. The study encompassed dorsal muscles in five fish species: common carp (Cyprinus carpio L.), rainbow trout (Oncorhynchus mykiss Walbaum) and Siberian sturgeon (Acipenser baeri Brandt), northern pike (Esox lucius L.) and grass carp (Ctenopharyn...
