the course of a month, the research boat along with other steamers and sailing vessels took ca. 

 700,000 cod. During the entire spawning season (February— April) ca. one and a half million 

 cod were taken by these boats. The fishery experiments and the investigations into the occur- 

 rence of the pelagic eggs showed therefore perfect agreement in their result. If we now look 

 closer at bank I, as shown on a larger scale on Chart (Fig. 5), it will seem astonishing 

 how locally restricted the fish can also be here. There is shown on this chart an oblique 

 quadrilateral which bounds the place on which spawning cod could be chiefly caught during the 

 experiments of 1902. From the many figures representing the investigated stations at which

no cod were taken, it appears that energetic investigations were also carried on outside the 

 quadrilateral. 



The appearance of the fish shoals is also determined to a certain extent by hydrographical 

 conditions, the cold currents especially causing the fish to seek deeper layers. On the other 

 hand, the fish seem to come much nearer the coasts in very warm years. Thus in 1903, the 

 occurrence of the cod shoals on the Malangs ground was essentially different, the fish were 

 then found even in the fjords ; and the whole coastal waters had a temperature (up to 6°) 

 distinctly higher than the average temperature for the season in other years.
