APPENDIX F: HENKING _ 12 ~ 



The hake occurs but seldom apparently on the most southerly North Sea banks, 

 from which we may conclude, that it comes from the northern North Sea. 



8. Catfish (Anarrhichas). The average catch per day amounts to: 



1902 1903 



5-92 pounds 5'53 pounds. 



It is caught in all months: the curve has a steep rise and the maximum is almost 

 at the same place (March or April) in both years, then there is a gradual decline to the 

 minimum in December with almost complete disappearance. 



9. Sole (Solea). The following is the average catch per day: 



1902 1903 



I sort 6*82 pounds 8-94 pounds 



11 „ 2-60 „ 4-18 „ 



in „ O-Ol „ 0-03 „ 



9-43 pounds 13'15 pounds. 



The catch is fairly uniform in all months, but on the Sylt outer ground there was a 

 considerable rise over the average in October— November 1902 and again in November- 

 December generally in 1903. 



The most southerly banks of the North Sea are specially productive as regards soles 



10. Turbot (Rhombus maximus). The average catch per day amounts to: 

 4^^ 1902 1903 



^.* I— II sort I9'6i pounds 15-90 pounds 



y III „ 18-13 „ 24-77 „ 



37-74 pounds 40-67 pounds. 



Both years agree in having a distinct and sharply rising maximum in May and June ; 

 the quantity at the maximum is mjore than double the average. A second smaller 

 maximum lies in October, extending in December in 1903. The remaining months show 

 considerably smaller catches. 



11. Brill (Rhombus laevis). The following is the average catch per day: 



1902 1903 



7-43 pounds 6-94 pounds. 



No specially remarkable fluctuations occur in catches of this species, just as might 

 be expected from the small average. The fluctuations, such as they are, indicate a slight 

 increase in winter. 



12. Plaice (Pleuronectes platessa). The average catch per day is as follows: 



1902 1903 



I-II sort 4179 pounds 35-60 pounds 



III „ 294-21 „ ^79^45 „ 



336-00 pounds 2 15-05 pounds.
