The experiment on growing domestic oyster spat in the Black Sea waters is carried out by VNIRO scientists

Scientists of the Azov-Black Sea branch of VNIRO have started studying the growth and development of oysters from Vladivostok in the waters of the Black Sea. The research is carried out jointly with colleagues from the Pacific Branch.

Under the conditions of sanctions, the traditional way of acquiring young oysters (spat) abroad turned out to be limited for Russian oyster growers. On the basis of the mariculture of the Pacific branch of VNIRO, located on Popov Island, comprehensive work is underway to develop technologies for the factory production of Pacific oyster planting material. The technologies developed here are aimed at an important goal – providing the country's farms engaged in shellfish breeding with domestic raw materials.
 
In this regard, there are questions of studying the development and adaptation of oyster spat obtained in the Pacific region in the conditions of other fisheries basins. It is this task that the joint research work of the Azov-Black Sea and Pacific branches of VNIRO is designed to solve.
 
At the end of March, young Pacific oysters delivered from Vladivostok were placed on special cage carriers by employees of the Azov-Black Sea and Pacific branches in two specialized farms located on the Caucasian and Crimean coasts of the Black Sea. On these carriers, young oysters will grow and develop in the sea over the next years.
 
"From the same batch, young oysters were placed on carriers and at the experimental base of the Pacific branch. Throughout the whole process of commercial cultivation, we will constantly monitor the development of oysters in the Black Sea water – study growth rates, survival, exchange data with colleagues from Vladivostok, who will monitor the development of their batch," says Victoria Khorosheltseva, head of the aquaculture center of the Azov–Black Sea branch of VNIRO.
