APPENDIX F: HENKING _ 6 — 



The greatest catches in both years were made in the warmer months. 



The hydrographical depth-charts appended, show that in 1902, oceanic water of over 

 35'25%o extended in August far over the North Sea plateau. In this month, it is 

 true, only three German steamers were fishing in the north, but I am quite certain, that 

 the, rich catches of haddock are not made in the water with high salinity, but in water 

 under 35-25 %o. 



In November again, the German steamers were fishing further north than in August; 

 as the curve of 35'35°/oo water is inclined towards the east, the catches were made in 

 the medium kind of water with 35'00— 35-25 7oo salinity. 



It is probable for 1903 also, that the catches of the few steamers were made in 

 water of less than 35'25%o salinity. 



2. Whiting (Gadus merlangus) is greatly mixed with the Haddock (IV sort) in 

 the catches of the German boats. The maxima seem similar to those of the haddock. 



3. Cod (Gadus morrhua L.). The average catch per day for the whole year, amounts 

 in pounds to: 



1902 1903 



I Sort 68-23 pounds 78-74 pounds 



n „ 10978 „ 129-53 „ 



178-00 pounds 208-27 pounds. 

 The maximum here, occurs in the second half of the year. 



4. Ling (Lota molva L.). Average catch per day in pounds: 



1902 1903 



20-79 pounds 15-91 pounds. 



Two unimportant maxima occurred in 1902, in March and October — November. In 

 the months of mid-summer, there is an unmistakeable depression in the catch. 



The available portion of the fishery for 1903 is not in opposition to this, only, the 

 first maximum is in April or perhaps May. 



5. S ai the und Pollack (Gadus virens L. and Gadus pollachius L.). Average 

 catch per day in pounds: 



1902 1903 



23-89 pounds 1 7-09 pounds. 



A distinct maximum lies in October to December 1902, a second, indistinct, in March. 

 In August, an unmistakeable minimum occurs. 



The available data for 1903 agree perfectly with these results. 



6. Gurnards (Trigla). Average catch per day in pounds: 



1902 1903 



28-21 pounds 6-03 pounds. 



In 1902, a high maximum occurred in August, a smaller in February.
