Dissertations, Master's Theses and Master's Reports

Remote Site Incubators (RSIs) were developed for the incubation of salmonid eggs directly at a field site to enhance success and imprinting of young. These have been employed in the re-establishment of Arctic Grayling in Montana and are being laboratory tested for possible reintroduction of this species in the Big Manistee River, MI. Arctic Grayling, Rainbow and Brook Trout eggs, obtained from state hatcheries, were reared in a laboratory using flow through lake water to assess egg and fry survival using RSIs. Dead eggs and fry were removed daily and observations of developmental stages recorded. Rainbow Trout eggs were evaluated …
