Abstract


This work presents results on behavioral reactions and sensitivity of molluscs and fish to experimental modelling of accidental oil pollution during the first 72 hours. It is shown that mobile hydrobionts, such as fish attempt to escape the contaminated area during the first 24 hours after the oil spill. Benthic animals – molluscs are more susceptible
to pollution, they almost instantly lose their mobility, become inert and try to escape their shells further on, which serves as an evidence of death throes. Light crude with high content of paraffin was used for the present experiment.

Keywords
