 "The Preparation of the General Report on the Plaice Question, its present con- 

 dition", at the Meeting of the International Council, 27th September 1910. 



The General Report is unfortunately not so far advanced that it can be laid 

 before the Council. The reason is, that the Special Reports of the different States, 

 which were asked for by the Council in the resolution of July 1908, had not all 

 been sent in even by January 1st 1910 and are still to date incomplete. The 

 material in the hands of the General Editor, on the results of the international 

 plaice investigations, is still insufficient for the preparation of the General Report 

 in accordance with requirements. 



Of the special reports, the following have now been received: the Dutch 

 report by Dr. Redeke, the Danish by Dr. Johansen, the Belgian by Dr. Gilson, and 

 the first part of the German by Heincke und Henking; the first two deal in a 

 thorough manner with most of the questions affecting the plaice fisheries and plaice 

 biology which concern them, the third in the main only with the plaice fishery of 

 Oslend. Not yet to hand but promised with certainty are: the English report by Captain 

 Masterman and the second part of the German report by Heincke and Henking. 

 The former, the Enghsh report,, has already been received in an incomplete form 

 as proof-copy and will soon be completely published as Vol. Ill of the "Report on 

 the Research Work of the Board of Agriculture and Fisheries in Relation to the 

 Plaice Fisheries of the North Sea". This report contains a discussion of the results of 

 the well-known English market-measurements and fishery statistics from 1905 to 

 1908 in accordance with points 2 and 3 of the London resolution of 1907, but 

 does not touch upon the biology of the plaice. Of the English investigations in 

 the last mentioned field we have as yet only the summarizing reports of Garstang, 

 Hefford and Masterman in the "Rapports et Procès-Verbaux", and these only 

 show the available material in part and mostly only the older material. The 

 second part of the German report of Heincke and Henking could not be com-
