Abstract
The way to reproduce the lost part of the Black Sea mussel population by their settling in the mobile collectors of preserved biocenosis is proposed. The sexual reproduction of the preserved part of the population, without damaging the fertile species is recommended to use. The lack of the Black Sea mussel larvae at a distance of 15 km from the population proves the need for this study. The objective of the work is to create, after all, an effective biotechnology for obtaining a sustain-able firmly attached Black Sea mussel spat, elaboration of methods of its settling in the Black Sea and the reproduction of mussel periphytons. During the study the percentage ratio of fertile species to young fish and old age groups expressed as 55–65 % to 45–35 % is studied. Also mass assessment of this ratio in the sample of 10 stations is carried out. The conditions of optimum weather indicators for active veligers and veligers D. settling in artificial substrate of collector carriers are examined. Collector installations used in the experiment, after the studies, are applied to the cultivation of fertile species and creation of biocenosis of mussel periphyton in places of lost populations near the Novorossiysk Bay area.
