NUMBERS OF HADDOCK LANDED 



Dividing poundage by average weight gave the 

 number of fish landed — for each season, subarea, 

 market category, and year. Excepting subarea 

 values, all of these numbers are shown in the fol- 

 lowing tables. 



Tables 10, 11, and 12 show the numbers of 

 scrod, large, and total haddock landed, by sea- 

 sons and years. Relative contributions of scrod 

 and large haddock to the total, by seasons, are 

 shown in figure 9. Figure 10 shows the yearly 

 trends, and here it can be seen that much of the 

 variation in total landings by years is due to 

 variations in scrod landings. The importance of 



these small-sized haddock to the present fishery 

 is thus evident. 



SIZE COMPOSITIONS OF HADDOCK 

 LANDED 



Now having available the number of haddock 

 that were landed (in each season, year, subarea, 

 and market category), and having also the lengths 

 of samples of haddock (in each similar subdi- 

 vision), we estimated how many haddock of each 

 size were landed. This was accomplished by 

 multiplying the number of fish measured in each 

 centimeter size group by the proportion of the 

 number landed to the number measured. This
