Oysters and Mussels to Help Checking Water in Novorossiysk Bay

Date of publication: 20 October 2020

Black Sea mussels, giant oysters and brown algae will perform the function of pollution indicators.

Chernomortransneft joined hands with Moscow-based Transneft R&D, one of the leading think tanks in oil and petroleum products pipeline transportation, to launch an environmental project to create a biological test object site. Moreover, the Federal Supervisory Natural Resources Management Service (Rosprirodnadzor) has already issued a positive conclusion of the State environmental appraisal. And now the oil transportation company is getting ready to create a special site of biological test objects to monitor a certain Black Sea water area.

According to Chief Ecologist of Chernomortransneft Galina Chezganova, a similar project was implemented in the Peter the Great Gulf, the Sea of Japan (Kozmino Port) in 2014, and in the water area of the Björkösund Strait in the Gulf of Finland (port of Primorsk) in 2019. This is about the water environment monitoring using marine hydrobionts. Molluscs, namely the Black Sea mussel and the giant oyster bred in the territory of Maly and Bolshoy Utrish, filter a large amount of water, and all the substances found therein will somehow accumulate in their tissues. Marine organisms react even to slightest pollution of the water area.

Specialists will take out hydrobionts and analyse their tissues on a regular basis, thus monitor the water condition.

The site of biological test objects will be deployed at the berth No. 1 of Novorossiysk Commercial Sea Port in close proximity of Chernomortransneft facilities. It is stated in the expert opinion of Rosprirodnadzor that the environmental project is not fraught with any extra environmental burden and does not involve any risk, since no drilling, dredging or soil moving are anticipated. The use of mechanisms and machinery is reduced to a minimum.

The whole site is about dismountable hydro-biotechnical structures in the form of steel benches to be fastened to the berth’s pile trestles. The benches will house 30 bivalve mollusk cages, 18 headers and 12 special plates for self-colonisation of mussels and algae. The site structure in itself does not have any negative impact upon the environment.

The Company’s plan calls for the project to be implemented by mid-2021.
