Popis: | North American Burbot Lota lota maculosa occupy habitats from deep, cold lakes to prairie streams. Controlled laboratory trials were conducted to evaluate the growth, immune response, and thermal stress physiology of juvenile Burbot subjected to fluctuating, high diel temperatures. Age-0 Burbot from a captive propagation program associated with population restoration in the Kootenai River, Idaho, were tested in temperature cycles that imitated summer conditions observed in regional stream habitats. The diel temperature cycle for the treatment group varied from 18°C at night to 27°C during the day, whereas the control group was held at a constant temperature of 14°C. We evaluated survival, growth, feed efficiency, heat shock protein 70 (hsp70) levels, hsp70 gene expression, serum lysozyme levels, and proximate body composition in samples taken from fish before, during, and at the completion of the trials. Both treatments had high survival and similar growth rates, but the control group gained signi... |
