Abstract :	Several species of fish from a number of Maine lakes were analyzed for mercury in the late 1970s to early 1980s (Akielaszek and Haines 1981; Haines and Brumbaugh 1994; Haines et al. 1987; Hamilton and Haines 1989). We screened this data set to identify suitable lakes to be resurveyed. Selection criteria included: no major change in access, watershed development, or fish management practices; relative ease of access; presence of robust fish population to be resampled; and a time interval between sample periods of at least 15 years. Seven lakes were selected to be resurveyed. They ranged in size from 2 to more than 2000 ha and included three species of fish: lake trout (Salvelinus namaycush, long-lived, carnivorous), brook trout (short-lived, omnivorous), and white sucker (long-lived, bottom-feeder). For the original survey, detailed field and laboratory records were available from data archives.
