Distribution of age-2 cod Gadus morhua by 10-niin squares of latitude and longitude from NEFSC scrod landings data (t, live 

 weight), 1982-86, for quarters 1 (A), 2 (B). 3 (C), and 4 (D) in the Georges Bank-Southern New England region. 



shifted south and southwestward within SAR 521 to 

 shallower water and into SAR 526, resuming loca- 

 tions identified in quarter 1 ; however, the concentra- 

 tion on Georges Bank in SAR 523 was still present (Fig. 

 3D). 



Visual inspection of quarterly distribution plots for 

 each year suggested that these patterns of juvenile 

 cod concentrations persisted over varying year-class 

 strengths and stock sizes; however, in the interest of 



space, only aggregate plots are presented (Figs. 3A- 

 3D). Age-2 cod from strong 1980 and 1983 year-classes 

 (Serchuk and Wigley In press) exhibited the same 

 seasonal movements described above, as did age-2 fish 

 from the relatively weak 1982 and 1984 year-classes. 

 Similarly, no changes in observed annual patterns were 

 evident from 1982 to 1986, during which time spawn- 

 ing-stock biomass diminished from over 80,000 t to 

 about 33,000 t (Serchuk and Wigley In press).
