— 7 — APPENDIX F: HENKING 



The available data for 1903 give quite different results, the high catches, especially, 

 which help to raise the curve so high in August and September 1902, viz. 18274 ^^^ 

 86 pounds respectively, are here absent. 



7. Hake (Merluccius vulgaris Fl.) Average catch per day: 



1902 1903 



12-86 pounds 3-64 pounds. 



The hake had a prominent maximum in September with steep ascent from July — 

 August, and just as steep a descent to October; then, from January to March there was 

 a distinct falling-off to almost complete absence. 



In 1903, the average catch was distinctly less than in 1902. The reason for this 

 lies, on the one hand, in that the catch for each of the months was less than in 1902, 

 but more especially, in that this region was not fished in during September 1903. For 

 the rest, the result is just the same as for 1902: the curve rises in July — August 1903. 

 The form of the curve in December 1903 corresponds well with that for 1902. There 

 is an almost complete absence of the fish in January to April (see Fig. 1, 2, page 19). 



8. Catfish (Anarrhichas lupus L.). Average catch per day: 

 1902 1903 



5'47 pounds 8'8o pounds. 



The curve of the catches of this species shows, for both years, apart from minor 

 fluctuations, a tendency to rise during the first months of the year, but a distinct fall 

 again from July — August onwards. 



The maximum accordingly, lies about July, the minimum in January. 



9. Sole (Solea vulgaris Quens.). This species lives in the more southern parts of 



the North Sea, and further is considered more a dweller in the shallower coastal regions. 



It is in agreement with this, that the sole is only represented in our catches by an 



average of:

The quantities are too small to demand further consideration. nT^ - 



10. Turbot (Rhombus maximus L.). This species likewise lives more to the 

 south and in smaller depths. Our catches agree with this.
