LJUBOJEVIC, D., D. TRBOVIC, J. LUJIC, O. BJELIC-CABRILO, D. KOSTIC, N. NOVAKOV and M. CIRKOVIC, 2013. Fatty Acid Composition of Fishes from Inland Waters. Bulg. J. Agric. Sci., Supplement 1: 62–71 The paper presents a comparative analysis of proximate and fatty acid composition of seven fi sh species from the Danube River including asp (Aspius aspius), common bream (Abramis brama), common barbe...

An active preference for higher temperatures within a physiological optimum is beneficial animal movement. For example, ascending induce an increase in cyprinid fish metabolism and swimming ability. Spring upstream migrations driven by the search resources may be related to these increases. Conversely, downstream autumn follow decrease temperature. When are resources, food availability reproduc...

Bar racks at water intakes of hydropower plants serve mainly to protect the turbines from floating debris. Additionally, they can be utilized downstream migrating fish in order prevent a potentially harmful turbine passage. The Rack FishProtector consists common bar rack equipped with electrodes mounted on upstream side bars. application low voltage current creates an electric field which is ac...

Assessments of patterns animal movements are important for understanding their spatial ecology. Geostatistical models stable isotope (SI) landscapes (isoscapes) provide a complementary tool to telemetry assessing and predicting movements, but rarely applied riverine species. Often single-isotope gradients in freshwater environments insufficiently variable high isoscape resolution at relatively ...

genetic diversity is one of the three levels of biodiversity. the aim of present study was to compare levels of genetic polymorphism between wild bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions, the coast of chamkhale and bandaranzali of gilan province. a total of seven microsatellite loci (mfw7, mfw26, mcs1eh,...
