 in the net increases o There are two opposing factors here. Tfhen

cco Special Fishing Methods whereby Undersized Fish Received Less Damage 



The fishery with seines and line trawls can be considered as siiche 

 The first type, that is the "snurrevaad* fishery in general use in 

 Denmarkj saves practically 100 percent of the undersized flatfisho 

 With this method the fish are not pushed together in a bag for hours 

 but are gradually d riven to the center by a concentric pushing over 

 the bottom of a line towed in a circle o Then they are brought on 

 board alive by a fairly smallj, wide^^eshed, dip neto The undersized 

 fishj, which may be still in the net, are then set free alive© This 

 type of fishing is done with the motor=cutters=comparatively smally 

 seaworthy ships=— manned by four meno 



The great advantages of this fishery are r 



r 



lo The good quality of the fishj ' . 



2o the protection of undersized fish and the 



protection of bottom=organism which serve 



as foodj, since the bottom is not disturbed by 



a heavy ground linei 

 3b the lower fuel consumption and less wear and 



tear of the geari 

 4o the very small likelihood of losing the gear, 



as compared with the trawl fisheryo 



The inherent drawbacks are that this method can be used Qijly 

 during the daytime and that during bad weather it has to cease 

 sooner than the trawl fisheryo These objections are felt especial- 

 ly during the winter months o Furthermore, very small amounts of 

 sole are caught with this methodo Presumably this is due to 

 peculiarities in the behavior of this species o Cod and haddock 

 are occasionally oaughtj although it is principally a plaice 'fishery. 



The disadvantage of the small catches of sole is made good by 

 the larger hauls of plaice and the smaller costs of exploitationo 

 The final drawback is that the technique is more refined and that 

 more intelligence and persistance is necessary than for the trawl 

 fisheryo 



The Danish fishery has increased enormou&Ly since the perfection 

 of this methodo The landings of plaice increased in Denmark during 

 a period when in other countries it was lowered or remained constant* 

 The Danes can keep without difficulty a minimum size of 26 centimeters 

 for their own use and a minimum size of 24o5 centimeters for export.
