COUNCIL — MAES 1920 . — 12 — 



fore only now to draw attention to the Baltic plaice question. At the meeting of 

 the Council in September 1913, a Recommendation was adopted for an agreement 

 between Germany and Denmark as to protective measures for Plaice and Flounder 

 in the Western Baltic. 



On account of the war, this agreement has not taken place officially by the 

 two countries in question, but it has happened that new fishery laws have been 

 carried in both countries during the war, and in these laws the said protective 

 measures, recommended by the Council, have been inserted. 



Point 7 of 'the Agenda. (The Herring and Salmon questions.) 



At the meeting of the Council in September 1913 it was resolved that a 

 Committee should be appointed to formulate proposals for the future conduct of 

 herring investigations on a wide scale. The Committee, for which Dr. Hjort 

 was elected as President, held a meeting in Copenhagen in April 1914, and drew 

 up a detailed programme for the investigations (see Procès-Verbaux Vol. XXI, 

 page 18). This programme should have been laid before the Council at a meeting to 

 be held in September 1914; this was, however, deferred on account of the war. 

 Nevertheless herring investigations have been carried out during the war by the neu- 

 tral countries: Holland, Norway, Sweden and Denmark, in accordance with the lines 

 laid down in the said programme. The results of these investigations will be dealt 

 with in the sectional meetings. 



As will be remembered, this question has been discussed by the Council in 

 order to have the biology of the salmon and the sea trout examined, to see, 

 whether international measures regarding size limits, hatching operations, etc. for 

 these fishes would be desirable in countries bordering on the Baltic. 



All these countries have participated in such investigations, and two reports 

 about the result have been given by Professor Henking (Rapports at Procès-Ver- 

 baux Vol. XVI, 1913, and Vol. XXIII, 1916.) The investigations have been continu- 

 ed during the war in Sweden, Germany, and Denmark, and after the lines laid down 

 in the programme published in the Procès- Verbaux Vol. XIV, 1912. A large material 

 concerning the growth and migrations of the salmon and sea trout has been collected. 

 Further report about the investigations will be given in the sectional meetings. 



Point 11 of the Agenda. (Other business.) 



At a meeting of delegates from the Scandinavian countries 

 and the Netherlands, held in Copenhagen from 23rd^ — 25th May, 

 1918, (see Procès-Verbaux, Vol. XXV) several of the above named questions were 

 discussed, in particular the plaice question and plans for continuing investigations 

 of plaice during the war, the Bulletin hydrographique, and the Swedish and Danish 

 investigations as to races of herring. Several administrative matters were dealt 

 with, and a lecture was given by Professor Gran about Investigations and experiments 

 during the last years about the reproduction of the plant plankton in the Christiania-
