Marine Ecological Journal| Резюме: | The results of long-term researches of the state of macrozoobenthos in the area of the deepwater sewage discharge in the Gulf of Yalta are given. In the period from 1969 to 2011, at depths of 70 to 94 m in total of 108 macrozoobenthos species were registered. Only 20 of species are permanent components of biocenotic complex Modiolula phaseolina (Mollusca, Bivalvia) existing in the area of research. In 1976 – 1986, compared with 1969 – 1970, the reduction of the macrozoobenthos species number from 75 to 39 was noted. The actual recovery of species richness (58 species) and abundance (4541 ind. • m-2) of macrozoobenthos in 2010 – 2011 up to the level of the late 1960s and early 1970s, as well as growth of the average biomass from 35 g • m-2 (1969 – 1999) to 152 g • m-2 (2010 – 2011) indicates the contemporary improvement of the ecological status the deep-water zone of the Yalta Gulf. An accordance between long-term changes of macrozoobenthos development and the commissioning stages of a deep-water discharge of domestic sewage was stated. |
