variation made it necessary to measure samples of 

 each category in evfry year for which we desired 

 an accurate measurement of size composition of the 

 total haddock landings. 



The amount of overlap in length between the 

 two market categories has been considerable. For 

 instance, haddock as long as 63 centimeters were 

 occasionally landed as scrod, and fish as small as 

 36 centimeters were landed as large haddock. This 

 was due to difficulties and mistakes in sorting had- 

 dock into two arbitrary categories at sea under 

 varying conditions of weather, haste, and so on.
