Stream Crossing Barrier Prioritization Methods For Increasing Eastern Brook Trout Habitat In The Little Androscoggin River Watershed, Michele Windsor

Thinking Matters Symposium Archive

Eastern Brook Trout (Salvelinas fontanalis) are an important cold water fishery in the state of Maine. While populations in Maine are relatively abundant there has been decline in some parts of its range due in part to loss of habitat connectivity. Brook trout require access to specific types of stream habitat for spawning, feeding, and seasonal thermal refuges. Stream crossing structures such as undersized, poorly installed, or blocked culverts, as well as small remnant dams, can create barriers to accessing important stream habitat for brook trout. A recent Fish Barrier/Culvert Survey in the Little Androscoggin River Watershed provided data about …
