many factors, known and unknown, tending to reduce the total numbers of a species, 

 when the life-history of such a species is regarded from the beginning to the end. 



These general considerations will, perhaps, counteract any false impression which 

 might be taken from the statement, that the trawling industry of the North Sea in general 

 and the fisheries of the plaice, sole, turbot and perhaps haddock in particular, are in a 

 critical condition. Unless the statistical data are worthless, the critical condition is evident; 

 this is considered due to the influence of man's fishing — a minor factor, perhaps, in 

 comparison with the other forces keeping the multiplying tendences of the fishes in check, 

 yet added to these and concentrated in a special direction — causing a diminution in the 

 quantities of the large and more valuable fish. On the other hand, nature's recuperative 

 power as well as the conditions of fishing, will not permit the reduction of the quantities 

 of fish below a very large minimum — so long as the present physical conditions prevail. 



The question, whether man by interfering with the methods of fishing, can help to 

 keep the stock of fish above this irreducible minimum, does not call for discussion. As 

 shown above, the possibilities one way or another are too numerous to be calculated; 

 it can only be solved by well-regulated experiments.

Notes on the Table showing the total quantities 

 It has to be remarked, that France is included here, as the quantities stated come 

 from the North Sea. On the other hand, Belgium has to be omitted and large quantities 

 included in the statistics for Germany, England and Scotland do not come from the 

 North Sea. At the present time, it is quite impossible to construct a satisfactory table, 

 showing the quantities of fish taken from the North Sea and these only. This explains 

 the indecisive nature of the heading to the table. 



The quantities given, refer only to the fishes; shell-fish, such as crabs, lobsters, 

 oysters etc., are omitted. These are mostly given in numbers in the various statistics 

 and as a rule form a separate subdivision. 



Sweden. It is quite impossible to ascertain the total quantities of fish landed 

 annually in Sweden. In 1902, the total value of the sea-fisheries, i. e. in the North Sea,
