COUNCIL - SEPT. 1910 - APPENDIX I — 100 — 



pleted earlier, as the extensive German market-measurements and fisheries statistics 

 on the plaice were only concluded on the 1st of January 1910. 



From Scotland, Sweden and Norway no summarizing reports have yet been 

 received, nor is there any promise of them. Some valuable material has been 

 sent to the General Editor from Scotland, but it deals almost exclusively with the 

 statistics of the plaice fishery from Aberdeen and contains nothing about the 

 valuable market-measurements. 



As the General Editor has repeatedly stated and as the International Council 

 has recognised in its resolutions, a proper General Report can only be drawn up 

 on the basis of the summarizing special reports of the different States. For this 

 reason chiefly, that the experts of each country are to express in these special 

 reports their views on the value of their material and on the possibility and use- 

 fulness of size-limits for the plaice within their district. It is now evident, how- 

 ever, that we cannot rely upon receiving complete reports from all within a 

 reasonable time and that consequently, as time is pressing for the completion of 

 the General Pieport, the resolution of the Council of July 1908 can no longer be 

 maintained. 



The General Editor proposes, therefore, that the resolution mentioned should 

 now be dispensed with and altered to read, that the preparation of the General 

 Report shall now be advanced, under the condition, that such material on the 

 plaice question as is not sent in printed or unprinted to the General Editor before 

 January 1st 1911 at the latest, cannot be taken into consideration in this Report. 



The General Editor requests however, that so much material as possible 

 should be sent to him up to the 1st of January 1911. Even if this increases the 

 work considerably, he is of the opinion that it will be quite possible for him to 

 present a satisfactory General Report. 



A summary was then given of the material already at his disposal, its value 

 for the Report was discussed and the shortcomings which might still be made 

 good were displayed. 



1. The spawning conditions of the plaice are now quite well known. 

 We find various, more or less well separated, spawning places, in the Southern 

 North Sea, the Northern North Sea, the Kattegat, Belt Sea and in the Baltic. Of 

 these the least investigated is the region in the Northern North Sea and further 

 material regarding it is very desirable. These different spawning grounds of the 

 plaice are however closely connected with the 



2. Existence of different local races of the plaice. These may be 

 regarded as proved with certainty. We can now quite well distinguish 6 such
