| Bottom sediments and macrozoobenthos were observed in the bays and adjacent open-sea areas of the south-western Crimean extremity. The investigations show a tendency of the bottom sediments to accumulate highly carbonized chloroform bitumoid and to increase zoobenthos biomass mainly due to the mollusk Tritia reticulata, polychaeta biomass reduced everywhere. Changes over a 6-year period appeared to be insignificant, which evidences for a relative ecological stability. |

| Tritia reticulata (Gastropoda) is widely distributed in various biotopes of the Black sea ad differs by its high resistance to unfavourable conditions, which makes it a convenient object when studying the effect of environmental fluctuations on the organism and population. The paper deals with the data on distribution, size and sex composition of the Tritia reticulata population under different ecological conditions and with the results of experimental studies on the Tritia reticulata survival under oil and phenol pollution as compared with other mollusk species. The number of Tritia is the highest at small depths (less than 20 m) and muddy grounds. With the rise in the content of chloroform extracted substances in the ground the number and biomass of... |

| The development of bacteria (total quantity of heterotrophs and hydrocarbon-oxidizing bacteria)and Protozoa in the ground, bottom water layer with oil added and without it was studied under experimental conditions as influenced by Nereis diversicolor O. F. Muller. It was observed that the bacteria quantity rose in the ground, dropped in the bottom water layer, except for the hydrocarbon-oxidizing bacteria in oiled water, where their quantity grew one order higher. Infusoria were not discovered in the ground. An increase of their quantity in the bottom water layer was statistically significant in all variants of the experiments, and was accompanied by changes in the species composition. |

| The study was made for macrozoobenthos of bottom sediments filling spaces between rocks. Four bays influenced by the anthropogenic factors of different intensity are compared with the open sea coast. Bottom sediments belong to carbonate organic debris sand ones and are characterized by the large size grains, low natural humidity (less than 40%), positive redox potential, weak alkali environmental reaction, relatively low accumulation of allochthonic substances. As compared with fine-grained bottom sediments of the same regions they are inhabited by a richer, as to species and quantity, macrozoobenthos represented mainly by sestonophages. The anthropogenic influence increases the content of ammonium nitrogen and chloroform-soluble substance bottom sediments... |
