"U.S. Seeks To Protect Threatened Bull Trout"

"SALMON, Idaho -- The U.S. Fish and Wildlife Service on Tuesday unveiled measures to help the threatened bull trout, a native fish whose cold-water streams in Western states could be warming due to climate change, but conservationists said the plan was too timid.

Under the plan, due to take effect on Wednesday, bull trout populations will be divided into six recovery units across five states, and efforts will be made to reduce threats such as the invasion of non-native fish species and barriers like temporary dams that stop the trout from swimming upstream to spawn.

The bull trout was believed to have vanished from about half its historic range when it was added to the U.S. endangered and threatened species list in 1998-99."
