APPENDIX F: HENKING _ 16 _ 



The catch is quite small in the winter months, December to April, and increases in 

 summer and autumn. In October 1903, it reached an average per day of 27-5 pounds. 



7. Hake. The remarkable occurrence of the hake in the Skager Rak is of as great 

 an interest as its occurrence in the other regions mentioned previously. The average 

 catch amounts to: 



1902 1903 



72-i6pounds 30-21 pounds. 



In spite of these great differences in the total quantities, the occurrence of the species 

 during the various months is quite the same for both years, and the separate curves are 

 very similar. 



There is practically no catch in January, February, March, April. Then a sudden 

 rise with high maximum in June (159 pounds average, 1903, as high as 413 pounds, 1902); 

 then a steep fall and gradual attenuation to December (Fig. 5, 6, p. 20). 



8. Catfish. The average catch per day amounts to: 



1902 1903 



15' 1 1 pounds i6'94 pounds. 



Both years agree in having the maximum with an average over 40 pounds in July, 

 the minimum at the end or beginning of the year. Further, the form of the curve is 

 very similar for both years. It is also remarkable, that the April maximum which occurred 

 for the southern North Sea, is distinct likewise for the Skager Rak. 



9. The sole only occurs in small quantities in the Skager Rak; the average catch 

 per day only amounts to: 



1902 1903 



I sort 0'63 pounds 0-69 pounds 



n „ 0-22 „ 0-32 „ 



0'85 pounds l -01 pounds. 



In spite of these insignificant quantities, there is an unmistakeable minimum in the 

 warm months (July, August) and a very distinct maximum in the winter months, 

 December — February ; these are clear for both years and are seen also in the precise data 

 of the journals. February of 1902 stands highest with 6'56 pounds, thus exceeding the 

 February average cf the southern North Sea, the true home of the sole. 



10. Turbot. The following is the average catch: 



1902 1903 



I-II sort 2-96 pounds 2'83 pounds 



III „ 1-11 „ i-06 „ 



4'07 pounds 3-89 pounds. 



The agreement in the catch of the two years is remarkable. Both agree also, in 

 having the minimum in summer and a considerable maximum in the last months of the
