Nové zařízení k ochraně ryb při poproudových migracích

Original language description

Examinations of the efficiency in the screen rotation were carried out continually during 96 hours. The passage of 18 fishspecies migrating downstream through this technical bypass, out from turbine anlages of a small hydropower station, was found. In total, the screen rotation put out 680 fish specimens with the decisive proportion of Stizostedion lucioperca (58,3 %) and Gasterosteus aculeatus (18,2 %). On those, 584 fish specimens werw healthy withoutany evident damages. The screen rotation net, meshed 15 x 8 mm, put aout G. aculeatus already of 27 mm, Leuciscus and Alburnus alburnus of 300 mm, Rutilus rutilus of 32 mm, Cyprinus carpio fry and Gobio gobio of 35 mm in standard lenght. O larger fishes, Anguilla anguilla, the lenght ones 610 mm, Acipenser ruthenus 320 mm, Perca fluviatilis 250 mm, Carasius carassius 245 mm, Scardinius erythrophthalmus 200 mm and Rutilus rutilus 175 mm were long.
