| Description
| - This study evaluates effects of different oxygen concentration to toxicity of complex cyanobacterial biomass and aqueous extract of two cyanobacterial samples (prepared with regard to content of the most studied cyanobacterial toxin microcystin: biomass 1 with content of microcystins 2560?g ? l-1 of dry weight and biomass 2 with content of microcystins 70?g ? l-1 of dry weight, i.e. almost 37-times lower concentration) during embryonal development of carp (Cyprinus carpio). Effects of complex biomass and aqueous extract were tested at concentrations 120, 80 and 40 mg ? l-1 in four replicates, two of them aerated and two without aeration. The studied endpoints included beginning and end of embryo hatching, the presence of eye points at 48 h after fertilization, filling of air bladder, cumulative mortality and glutathion-S-transferase (GST) activities in surviving embryos. There was significant increase in mortality in all variants without aeration after exposure to cyanobacterial biomass and aqueous ex

- Byl sledován vliv rozdílné výše koncentrace kyslíku na toxicitu surové biomasy a vodného extraktu sinic dvou druhů biomas sinic (připravených s ohledem na obsah nejznámějšího cyanobakteriálního toxinu, microcystinu: biomasa 1 s obsahem microcystinů 2560?g ? l-1 sušiny a biomasa 2 obsahem microcystinů 70?g ? l-1 sušiny - asi 37x nižší koncentrace) během embryonálního vývoje kapra obecného (Cyprinus carpio). V experimentu byla testována surová biomasa a vodný extrakt sinic v koncentracích sušiny 120, 80 a 40 mg ? l-1 ve čtyřech opakováních, dvě byla bez aerace a dvě s aerací. Během testů byl sledován začátek a konec kulení embryí, přítomnost očních bodů v 48h po oplození, po ukončení experimentu naplnění plynového měchýře, kumulativní mortalita a u přeživších jedinců i aktivita glutathion-S-transferázy (GST). Ve všech pokusných koncentracích bez aerace došlo k signifikantnímu nárůstu (p0,01) mortality. U variant s aerací rovněž došlo u nejvyšších koncentrací surové biomasy a extraktu k nárůstu mortalit (cs)
