TABLE VIII— PLAICE AND DABS, 1899-1013 



The same kinds and sizes of fish are present in the inshore 

 Maters in the month of August, but in 1920 small plaice were 

 conspicuously abundant in the northern part of the district, and 

 there was a scarcity of plaice throughout the Northumberland 

 district of the sizes above, and markedly of a size about 20 cm. 

 (8 inches). Dabs, on the other hand, were not very different in 

 1920 from the average conditions of the pre-war years. 



For the sake of comparison the detailed records reduced to 

 catch per hoar's trawling are given in parallel with the table refer- 

 ring to the marketable fish. There ought to be a degree of 

 resemblance between the plaice and dabs recorded by the former 

 above, say, 20 cm., and the marketable sizes of these species. 

 The detailed records rcfe L * to the period 1899 to 1920, and the years 

 common to both kinds of experiment are 1899-190G. The mean 

 for each bay with reference to catches of marketable plaice and dabs 

 and for the plaice and dabs over 20 cm. of the detailed hauls are : —
