In 1948, unmarketable haddock were most abundant in depth zone II. The weight 

 per tow uf "scrod haddock" v/as least m depth zone III and about evenly distributed in 

 the other depth zones. The greatest weight per tow of 5-9+-year old and 3-9+-year- 

 old haddock was in depth zone IV. The weight per tow of large haddock in depth zone 

 IV almost equaled the weight per tow of ail marketable haddock in depth zones I and 

 II, and the weight per tow of all marketable fish, both scrod and large, was almost 

 double that of other depths . 



In 1949 the greatest weight per tow of unmarketable, marketable, and scrod 

 haddock occurred in depth zone II. The greatest weight per tow of large haddock was 

 obtained in depth zone IV . Considering that the market price ratio of large haddock 

 to scrod haddock is roughly 3/2, the value of the catch in depth zone IV was consider- 

 ably greater than that of the other zones .

In 1950 the separation of the various age categories of haddock was, even more 

 marked. The greatest weight per tow of unmarketable haddock was again obtained in 

 depth zone II, while the weight per tow of 3-4, 5-9+ and 3-9+-year-old haddock was 

 greatest in depth zone IV- TTie weight per tow of large haddock alone in depth zone IV 

 was more than three times that of all marketable haddock in depth zone II. 



It appears, then, that as far as the haddock fishery is concerned, it would have 

 been both more profitable to the fishermen and more expedient from a conservation 

 standpoint to have fished in depths greater than 90 fathoms during this period.
