In 1950, the catch per tow was greatest in subareas J and M with 2 -year -old 

 fish making up the hulk of the total catch. Two -year -old fish dominated tJie catches 

 in subareas H, ], and M while zero-ring fish prevailed in subareas G, N, and O. 

 Subareas G and H again had the highest proportion of 5 year and older haddock and in 

 subareas N and O very few fish older than 2 years were cau^t. 



To summarize the subarea distribution in the summer, it may be stated that: 



1 . In all three years the catches of haddock 5 years and older were 

 greater in subareas G and H than over the rest of the bank . This fact is more 

 graphically illustrated in the following table (taJale 5) giving tJie catch per tow and 

 percentage of 5 year and older haddock by subarea. 



2. Subareas J and M had consistently the greatest conceeai^ation of 

 haddock, but the greater proportion of these fish were 1 -to -3 -year -olds. 



3 . in subareas N and O the catches were made up' principally of zero- 

 ring and one-year-old fish with older fish seldom observed.
