these comparisons. All comparisons between 

 Placentia Bay samples showed no significant dif- 

 ferences I Table 4). For the comparisons between 

 the two west coast samples and between samples 

 from each of the two areas, there were significant 

 differences for some size groups but not for others. 

 The relationships shown in Figure 2 indicate that 

 American lobsters in Placentia Bay are more 

 fecund than those on the west coast. This observa- 

 tion is supported by the analysis of covariance and 

 to a lesser extent by the analysis of variance. 



Data for the three Placentia Bay areas were 

 combined as were data for the two west coast 

 areas. The curvilinear relationships derived from 

 log-log regression analysis were plotted with those 

 available from the literature for other areas (Fig- 

 ure 3). Substantial differences in size-fecundity 

 relationships between some of these areas are ap- 

 parent. 



Perkins ( 1971) reported substantial egg loss dur- 

 ing incubation (36% between October and June) 

 for American lobsters from the offshore canyon 

 areas of the northeast United States. This should
