Laichgebiete des Dorschs in der westlichen Ostsee
Analyses of the previous years showed that the reproductionof the Belt Sea cod stock (Gadus morhua morhua) is also very important for the cod stock of the central BalticSea (Gadus morhua calarias). Oeberst (1999, 2000) proved, that between 20 % and 50 % of the cods caught in the Bornholm Sea at the...
