During 1983, the numbor of crabs and fish caught in each trap were 

 recorded to examine the influence of competing species on lobster catch. 

 Crab abundance was greatest at IN with more crabs than lobsters being 

 trapped in 18 out of 20 pots (Fig. 3). To identify the effects of crabs 

 and fish on lobster catch an analysis of covariance was performed on the 

 catch of lobsters in each pot using the numbers of crabs and fish caught 

 and soak time (number of days between pot hauls) as covariates. The 

 analysis indicated that the main effects of month, station, and pots within 

 station were significant (Table 3). Also, the abundance of crabs and fish 

 in the pots and the amount of time between pot hauls were significantly 

 correlated with the catch of lobsters. Since this significant correlation 

 implies that mean CPUE estimates per pot will be biased (the numbers of 

 crabs and fish caught are different for each pot) , the means adjusted for 

 the covariance provided by the SAS GLM procedure were used as mean CPUE 

 estimates per pot (Table 4). Richards et al. (1983) reported that traps
