Annual CPUE's and approximate 95% C.I. for wire pot data are presented in Table 7. These CPUE's 

 were computed as the geometric mean of the ratios of (no. lobsters) to (no. wire pots), because these 

 ratios are nonadditive and have an asymmetric distribution about the arithmetic mean. Therefore, the 

 geometric mean is the best statistic for constructing C.I.'s which should be asymmetric. Based on the 

 inspection of the C.I.'s in Table 7, the 1980 and 1981 CPUE's were the lowest annual values of all years 

 from 1978 to 1985. Conversely, the 1982 CPUE was the highest armual value when all years were 

 compared and was due to a strong prerecruit class in 1982 (also apparent in the 1982 frequency distribution 

 - see next section) which sustained record landings in 1983 and 1984 when these lobsters molted to legal 

 size.

 lobsters caught in wire pots at all stations from 1978 through 1985. 



Population Characteristics 



Size Frequencies 



Annual size frequency distributions for male and female lobsters caught in wire pots from 1979 to 

 1985 are shown in Figure 3 and for each station in Figure 4. Population statistics for lobsters caught from 

 1976 to 1985 are summarized in Table 8. Annual mean CL's have been consistent since lobsters have 

 been collected using pots. The mean CL of lobsters caught in wood pots was greater (range 73.3-76.6) 

 than the mean CL of lobsters caught in wire pots (range 70.8-71.8).
