| Impact Description | A study by Grant (2002) in Valley Creek, MN, confirmed that hybridization between male brown trout and female brook trout occurs in the wild, resulting in a hybrid fish known as tiger trout. It also indicated that the interference of brown trout in conspecific brook trout reproduction could contribute to declines in brook trout populations |
