A high sensitivity of the sea urchin Scaphechinus mirabilis embryos and larvae to sodium dichromate was revealed. This fact allows to use them as test-objects in the bioassay of the marine water pollution. Impact of hydrocarbons of the diesel fuel water-soluble fraction on embryogenesis of S. mirabilis was assessed. The effective concentrations which cause disturbances in embryos and larvae were calculated. It was stated that actual state of the Peter the Great Bay pollution by petroleum hydrocarbons can potentially disturb reproduction of the sea urchins.
