Современное состояние промысловых биоресурсов Чёрного моря

2009 
Results of the retrospective analysis of all available materials and perennial studies of the commercial bioresources of the Black Sea are generalized. It is shown that the last years in contrast with the end of the 80-s and a first half of the 90-s of the XX century the state of biological resources improves. The stocks of the Black and Azov sea anchovy are restored to the level of the 1970-s. The stock of sprat was at the level of average annual values. The stocks of haarder and whiting are found at the satisfactory condition. State of stock of sturgeon and black sea turbot, which is found on galley proof of the destruction, causes the alert. As a result of wide spreading ecological plastic nonnative shellfish species (Rapana venosa and Anadara inaequivalvis) are noted the essential changes in the structure of the benthic biocenosis. The reduction of the commercial macrophytes stocks on the Crimea shelf, unlike northwest part of the Black Sea, is not catastrophic, but their state does not allow recommending their catch. The concrete recommendations for exploitation of commercial bioresources stocks in the Azov-Black seas region are given.
