BIOASSAYSAND BIOINDICATION METHODS Clause Samples

BIOASSAYSAND BIOINDICATION METHODS. Biomonitoring of waters in the Ukrainian part of the North-Western Black Sea (NWBS) shelfwas carried out in the summer-autumn season of 2019, using bioassay and bioindication methods. The bioassay was based on responses of larvae of Black Sea mussels at early stages of development. The bioindication method used laboratory culture of microalgae and so- In the period of 2016-2019, a deterioration of the ecological status of surface waters and near-bottom waters was observed in the area of the marine protected area Zernov's Phyllophora Field. The area adjacent to Cape Malyi Fountain in the coastal zone of the NWBS was found to provide favourable conditions for the life of hydrobionts. The worst ecological conditions for the life of aquatic organisms were determined in the aquatic and bottom environment of the sea near Zatoka, Chornomorsk, Dacha
