The Pipeline Transport Institute and Transneft Primorsk Port have launched an aquaculture test ground for environmental monitoring in the waters near offshore oil terminals.
900 fishes (Baltic whitefish and trout) were selected as test objects. They were placed in special enclosures inside a submersible platform near the oil terminals. Environmentalists will assess the impact of the port on the ecosystem of the Gulf of Finland in the Baltic Sea on the basis of observations of the state of the fishes.
Even a small amount of toxic substances in the water leads to their accumulation in the tissues of marine organisms, as a result of which the tissues begin to change. The technology used at the test ground is aimed at monitoring and measuring these changes over time.
“We will periodically take samples of the fishes and monitor their growth and development, as well as the state of internal organs, first of all, the liver, because it accumulates petroleum products and various toxins associated with human economic activities. This is an objective indicator of the ecological state of the water area in the long term,” said Arina Nikolayeva, Head of the Environmental Safety and Rational Nature Management Laboratory, The Pipeline Transport Institute.
Employees of the Pipeline Transport Institute started developing this environmental monitoring technology in 2017. In order to conduct research, a test ground for aquaculture was designed and built. Monitoring studies are scheduled to begin in late July 2019.
The purpose of the test ground is to demonstrate that Transneft Primorsk Port’s facilities are safe for the environment.
