COUNCIL-MARCH1920-RESOLUTIONS — 38 — 



Resolution 30. 



That owing to the profound effects upon the stock of fish in the North Sea, produced 

 by the conditions prevailing during the war, it is necessary to ascertain as fully as possible 

 the present conditions now obtaining on the North Sea fishing grounds. 



Resolution 31. 



That the evidence now available indicates that the closure of limited areas of the North 

 Sea to steam trawling and.trawhng by highly powered motor fishing vessels, would be of benefit 

 to the plaice fisheries. 



Resolution 32. 



That since the question of closed areas is to be further examined, and special investiga- 

 tions are to be undertaken in this connection, the resolutions of the Plaice Committee of 1913 

 as to the impositions of size limits should be reconsidered also. 



The sub-section agrees to a programme of further researches for the ensuing twelve 

 months outlined in the schedule attached, with the object of providing material which may 

 form the basis of new proposals for the protection- of the plaice fisheries and recommends 

 accordingly. (See also page 59 & 73).
