Heritage Brook Trout in Wisconsin: Identification and Genetic Variability among211 Populations

摘要

Genetic analyses of one hatchery brood stock and 17 wild brook trout populations211u001e(either no stocking history or stocking occurred = or > 20 years ago) from 211u001eWisconsin were made to: (1) identify key genetic parameters for identification of 211u001eheritage populations, (2) identify naturally occurring regional genetic 211u001edifferences, and (3) determine the genetic impacts of severely limited habitat 211u001eand small populations. Sampled populations represented every major watershed and 211u001eecoregion of the state. An additional wild brook trout population from Iowa as 211u001ewell as the Iowa hatchery strain were also included in the genetic analyses.
