Overall totals (N) are given for each season. are still widely distributed throughout the northern part of the Gulf and the Estuary (Figure 5d). Two adults tagged on the Nova Scotia eastern shore were recovered from this same region during the July-September period. Age Structure Total recoveries in the Gulf of known age indi- viduals (N=4308), including tags of all origins, were composed of pups, adults and juveniles. Due to insufficient sample sizes, differences in age structure could only be examined between July-September and October-December and between the Estuary, Anticosti Island, the northeastern Gulf, Magdalen Islands and southern Gulf areas. Population age structure in the bounty returns (N=3658) was not independent of region (Table 5) during summer (July-September; x^=, df=8, p<) or autumn (October-December; x-=, df=8, p<). During the summer, pups were under-represented, and juveniles were over- represented in bounty returns from the Estuary, pups were over-represented and adults were under- represented in returns from the northeastern Gulf, while relatively few pups were recovered from the southern Gulf. In the fall recoveries, more juveniles and fewer adults then expected were recovered in the northeastern Gulf, more pups and fewer juve- niles then expected were recovered from the
