interval a female index of maturity was obtained (Briggs and Mushacke 

 1979; Ennis 1980; NUSCo 1981a). 



The size of the local lobster population was estimated using the 

 method of Jolly (1965) as modified by Seber (1965). This multiple 

 census method uses tag and recapture data collected from an open population 

 in which recruitment, immigration, mortality, and permanent emigration 

 are operable. 



RESULTS AND DISCUSSION 

 Physical Measurements 



Water temperature and salinity were measured from May through 

 October (1979-81) . Bottom temperatures ranged from 7 C in early May to 

 22 C in summer, and were up to 2.1 C lower than corresponding surface 

 temperatures (Table 2) . Temperatures (surface and bottom) at Jordan 

 Cove and Intake (4 - 6 m in depth) were similar to each other, but 

 consistently warmer than at Twotree (12 m) . 



Salinity was constant between stations and between surface and 

 bottom; values ranged from 29.1 - 32.0%.. Due to the spring freshwater 

 runoff, salinities were 1.2%. lower in May and June than in the rest of 

 the sampling period. 

 Abundance and Catch Per Unit Effort 



A total of 27,019 lobsters was collected in the study area from 

 1975-81 (Table 3). The data collected prior to 1975 is not presented 

 due to inconsistencies in sample design which render it uncomparable to 

 the 1975 - present data base. The increased catches from 1978-81 were 

 the result of the addition of wire pots into the sampling program 

 (Table 4) .
