On the joint influence of body size and water temperature on the growth rate of the Pacific oyster (Сrassostrea gigas, Thunberg) in the Donuzlav Liman (Black Sea)
The Pacific oyster (Сrassostrea gigas, Thunberg) is a cultivated species of a world-wide importance, which results in the relevance of the investigation of its growth rates in various areas of the World Ocean. This parameter defines the time needed for an individual to reach its commercial size and...

The Pacific oyster (Сrassostrea gigas, Thunberg) is a cultivated species of a world-wide importance, which results in the relevance of the investigation of its growth rates in various areas of the World Ocean.
