1 86 MARKETABLE BRITISH MARINE FISHES 



when these fish were most abundant in the Channel were 1889 

 and 1890. In the summer of the former year the catch in the 

 Zuyder Zee was one of the smallest, in the latter year it was the 

 largest ever known, and in 1891 it was also large. The question 

 therefore arises whether the number of anchovies which pass up 

 to Holland have all been hatched there, or whether they are 

 recruited from the south ; that is to say, whether a mild winter 

 allures the anchovies northwards towards the Channel, and they 

 then with the approach of summer pass northwards instead of 

 southwards to spawn. Then again it is possible that the fish 

 may be very abundant off the coast of Holland but not enter 

 the Zuyder Zee.
