Figure 8. --Comparison of length composition of the autumn catches of scup by the summer fishery and the 

 winter catches by the southern trawl fishery. The curves above the double lines are percentage distributions 

 of sizes obtained by random sampling of the landed catches. The two sets of curves in the lower part of the 

 graph are based on data weighted according to the number of fish landed (total catch) and amount of fishing 

 effort (catch per day). 



waters and move offshore to join the concen- 

 trations of older and large- sized fish exploited 

 by the vessel fishery (purse seiners and otter 

 trawlers). Evidence of this change is shown 

 in figures 6 and 8 and tables 9 and 10. For 

 example, the 1927 class was available to the 



New Jersey inshore pound nets from 1928 to 

 1931. In the latter year, the fish of the 1927 

 brood, then 4 years old (fig. 6), constituted 

 a large part of the May and June catches 

 there, but from July to the end of the season 

 (November) they moved offshore to areas
