Chromosomal Aberrations in Early Embryos of Weatherfish (Misgurnus fossilis L.) Exposed to Crude Cyanobacterial Extract and Semipurified Compound of Microcystins ? pilot study

Popis výsledku v původním jazyce

The genotoxicity of semipurified compound of microcystins and crude extract of cyanobacteria was analyzed and assessed using detection of chromosomal aberrations in early life stages of weatherfish. For 96 hours, weatherfish eggs at an eye spot stage were exposed to semipurified compound of microcystins (MC-LR: ?MC= 1: 2.6) and crude cyanobacterial extract (MC-LR: ?MC= 1: 2.1) both in doses of 130, 50 and 13 ?g ? 1-. Hatching time in individual groups and aberrations in the behaviour of hatched specimens were recorded. Cumulative mortality and the proportion of deformed specimens were determined; materials for histological and cytogenetic screening were simultaneously sampled. Cumulative mortality (28 and 26%, respectively) increased after the application of higher doses (130 and 50 ?g ? 1-) of crude cyanobacterial extract (p<=0.05). In these groups, hatched embryos showed reduced agility and stayed in clusters and in the group with the highest dose of crude cyanobacterial extract whit
