mer and autumn, with summer samples indicating smaller slopes 

 than either of the other seasons. Significant differences were 

 also evident in adjusted means between summer and autumn. 



Differences in L. pealei length-weight regressions were also 

 found between areas (Table 4c). The slope from the southern 

 New England regression was significantly greater than that of 

 the Mid-Atlantic, Georges Bank, and Nova Scotia areas, in- 

 dicating statistical difference between each of these regression 

 pairs. Comparisons revealed that adjusted means from the Mid- 



Atlantic area were significantly greater than from Georges Bank 

 or Nova Scotia, while the mean from the Nova Scotia regression 

 was also significantly less than from both Georges Bank and the 

 Gulf of Maine. There were no statistical differences in regres- 

 sions for the Mid-Atlantic and Gulf of Maine; southern New 

 England and the Gulf of Maine, and Georges Bank and the Gulf 

 of Maine. 



Pairwise comparisons between years (Table 4d) produced no 

 significant difference in the slopes in any year. However, there
