time from 1986 to 1990. In 1991, less detailed sampling 

 was carried out by the Department of Fisheries of the 

 Province of Newfoundland and Labrador. Sampling 

 focused on lobsters in Indian Arm (transplanted in 

 1982) and at Goose Island (transplanted in 1985) (Fig. 

 1). These two sites were selected to include lobsters 

 from the earliest and latest transplants. Also, in initial 

 trap sampling in 1986, lobsters were caught more 

 readily at these sites than at others. Lobsters were 

 caught in baited traps in 1986, 1987, and 1991 and by 

 scuba-diving from 1988 to 1990. Samples over the 6 

 years totaled 295 males and 392 females. Numbers 

 included in sampling for various purposes described 

 below are summarized by year and sampling site in 

 Table 1. Carapace length of each lobster was measured 

 to the nearest mm. Shell condition was determined by 

 external macroscopic examination in 1986 and 1988- 

 90. In over 90% of the lobsters examined for shell con- 

 dition, those that molted the previous summer (new 

 shell) could be readily distinguished from those that did 

 not (old shell) by general brightness of coloration, 

 sharpness of spines, and the degree of darkening due 

 to abrasion on the leading edges and undersides of the 

 claws. The others could be categorized with reasonable 

 confidence. Each summer from 1987 to 1990, sub- 

 samples of nonovigerous females totaling 111 for the 

 4 years were sacrificed. For each of these, ovary 

 color, ova diameter, contents of seminal receptacles,
