A giant meront containing thousands of merozoites has been found in the intestinal epithelium of an adult specimen of white bream (Blicca bjoerkna). The taxonomic position of this unusual coccidian stage is discussed.

Zooplankton was the only food component of common bream and silver bream, and the main food component of roach and bleak in the pelagic zone of the Dobczyce Reservoir (southern Poland) from April to October 1994. Cladocera and Copepoda constituted 67.9% of the food consumed by the whole fish community. The average size of eaten individuals ranged from 0.62 to 1.43 mm. Planktivorous fishes selec...

In this paper, there was investigated the content of mercury in soil, plant, water, and hydrobionts Kyiv Obukhiv district region. Studied territory is characterized by high anthropogenic load. The solid waste landfill region highest Hg soil. concentration Taraxacum officinale L. among all studied plants, hence possibility recommending species for phytoremediation mercury-polluted soils. Mercury...

we collected silver bream blicca bjoerkna from march to july 2013 from aras dam lake (north-west of iran) and investigated its age, size, and some biological characteristics. the maximum age was 5 + years. the total length and weight of specimens ranged 137-278 mm and 26-247 g for male and 134-282 mm and 26-289 g for female, respectively. length-weight relationship was estimated as w = 1e-06tl ...

The egg-release, mating, courting and aggressive acts for the spawning behaviour as well as the survival rates after spawning at stages of eyed embryos, viable hatchlings, and larvae to dry food consumption for the mating success were studied in cultured silver bream Blicca bjoerkna × rudd Scardinius erythrophthalmus hybrids at their first sexual maturity. Experiments were conducted in experime...

METHODS A parasitological investigation was done on 78 specimens of B. bjoerkna and 114 of H. leucisculus. The fishes were collected from August 2009 to Apri...

Lactobacilli are Gram-positive and catalase negative rods commonly found in lactic acid fermented foods and in the gastrointestinal tract of mammals and birds. Few studies have described lactobacilli in freshwater fish. We analysed the presence of lactobacilli in the intestines of young and adult freshwater fish inhabiting a river environment and from fish reared in an aquaculture unit with a w...
