Abstract
FOR many years the problem of how the stock of plaice in the Baltic Sea is recruited has occupied biologists of that region. Peterson's view, expressed in 1894 (Report Danish Biol. Stat., 4, p. 13) and again in 1906 (Cons. Internat. Rap. et Proc. Verb., 5), was that the numbers were renewed by immigration from the German coasts around Kiel Bay. A. C. Johansen came to the conclusion that the deep water of the Baltic itself was the real home of the O-group in the eastern Baltic, whilst Reibisch concluded that this was not sufficient to account for the renewal of the whole stock, and that an immigration of adult plaice took place from the Kattegat and the western Baltic.
