Influence of cyanobacterial water blooms and their fractions on the early developmental stages of fish

Popis výsledku v původním jazyce

Cyanotoxins can markedly negatively influence early life stages of fish depending on the quantity and kind of cyanobacterial biomass. They increase embryonal and larval mortality and amount of malformed individuals, decrease fry size, cause abnormal behaviour. Chronic exposure of larvae also to lower doses of cyanotoxins exhibits higher death during the following rearing. Dystrophic changes of liver were observed up to older stages of fry, in younger larval stages high mortality and retarded developmentmay be due to increased energy demand of detoxication processes and histological damage is not evident. By the study of cyanobacterial fractions the most pronounced toxic effects were found at the complex biomass and the crude aqueous extract regardlessof microcystin content and permeate fractions (microcystins removed) of two samples dominated by Aphanizomenon sp. and Planktothrix sp. The results of the experiments with different oxygen saturation clearly showed important impact of ox
