Effects of beaver (Castor canadensis) impoundments on stream temperature and fish community species composition and growth in selected tributaries of Miramichi River, New Brunswick / by M. D. Alexander. : Fs97-6/2227E

The objective of this study was to identify the effects of beaver impoundments on stream temperature and fish community species composition and growth. It was hypothesized that 1) water temperature increases as it moves through an impoundment resulting in higher outflow temperatures; 2) differences in stream temperature and habitat characteristics in and directly downstream of impoundments would be reflected by alteration in fish community species composition; and 3) growth indices would be greater for those species that inhabit impoundments as a result of the altered temperature regime.--Introduction
