— 5 — APPENDIX F: HENKING 



The greatest difficulty in the way of estimating the value of the catches of the 

 steamers lies in the exact determination of the fishing-grounds. I believe, however, that 

 we have succeeded in determining the fishing-grounds with sufficient accuracy for the 

 years igo2 and 1903, to be spoken of here. How that has been done has been explained 

 in the annual report of the Deutsche Wissenschaftlichen Kommission for 1903 ^ 



The catches of the Geestemünde steamers have served for the calculations of 1902; 

 for 1903, those of the Bremerhaven steamers have been added. 



In the course of 1904, thanks to the advances made by the circles concerned, similar 

 data for Hamburg, Altona and Nordenham have also been placed at the disposal of the 

 Deutsche Seefischerei-Verein. This attained, the whole fleet of German steamers 

 has been won over to the work. 



In the following, a review will be made over the various fishing-regions which come 

 into consideration. 



I. The northern North Sea 



I include in this the Great Fisher Bank, the Fladen Ground, the Long Forties and 

 the portion of the North Sea plateau lying to the north of this, as far as the Shetlands 

 in the west. 



The material for 1902 has been gained from 137 voyages of steamers. In the months 

 of May, June and July the northern parts of the North Sea are not frequented by the 

 fishermen from Geestemünde. The number of the fishing days, including the days sailing, 

 amounted to 1.35,5. 



In 1903 the northern North Sea was visited by only 23 steamers with 230 days in all. 



As the German steamers do not fish in the north in all months of the year, the 

 material has therefore some gaps. Nevertheless there are always certain signs, the breaks 

 in the curves of the catches can be filled out by estimations. 



The quantities of fish in 1902 and 1903 were constituted as follows: 



1. Haddock (Gadus aeglefinus L.). The average catch per day over the whole 



year, amounts in pounds ('/z kg.) to :

Two distinct maxima occur in the catches in 1902, namely, a smaller in March, a 

 larger in August. 



These two maxima are found equally in all four sorts. 



In 1903, the first maximum occurred already in January, the second in July to August.
