Controlling the non-usage of imdersized fish will be extreme- 

 ly difficult in these areas. Many trawlers fishing there have 

 fish meal installations on boardo Howe-zerj it is not expected 

 that they will deliberately fish for trash fishp since tliat will 

 not be profitable on these expensive voyages o 



It seems impossible, at the moment, to determine how 

 intensive the fishing may be in the northeast Atlantic areao 

 The best means to prevent overfishing in the future will be to 

 have a continuous control of the changes in the fish stock, 

 whereby the passing of the point of overfishing most probably 

 can be established in time, so that restrictions can be effectedo 



III. SUMMARY 



In the first chapter it was explained that the quantity of 

 fish which a sea can deliver is limitedo The productive power 

 of the fish stock of an area changes with the magnitude of the 

 stocko For a certain numerical strength corresponding to a 

 certain fishing intensity, it will be possible to harvest a 

 constant optimum catch of this fish stocko 



Next it was shown that the intensity, with which the bottom 

 fish in the North Sea was fished during the years 1930=40, 

 was much higher than the fishing intensity which corresponds 

 to the optimum catoho Hence there was a state of overfishing© 



On the basis of statistics on the North Sea fishery gathered 

 during the last 40 years, one may estimate the catch of bottom 

 fish from the North Sea at 390 million kilograms each year© 



It is necessary that in the future the North Sea fishery 

 be fixed by international quotas so that no more than 390 

 million kilograms of bottom fish will be caught each year* 



To receive as high a return as possible and to see to it 

 that sufficient fish become fully developed (sexually), it is 

 desirable to minimize the catch of non-marketable and very 

 oheap-consumption fisho 



A documented survey was given of the measures with which 

 the above could be obtained and it was explained which measures 

 would give the most protection for the young fish in the North 

 Seao A sijmmary of the advisable regulations is given on page e
