The effect of water temperature on angling catch of Atlantic salmon in the Upsalquitch River / by F. Mowbray and A. Locke. : Fs70-1/1999-56E-PDF

This study addresses water temperature effects on Atlantic salmon angling using catch and effort records for four New Brunswick Crown angling reserves on the Upsalquitch River, N.B. Salmon abundance and morning temperature (0800 h ± 1 h) are monitored at a barrier fence located upriver. The following questions are asked: 1. What are the morning water temperatures in the Upsalquitch River? 2. How do these temperatures compare with those measured in the main Retigouche River, approximately 100 km downstream? 3. At what time of day do minimum and maximum water temperatures occur? 4. How much angling takes place at high temperatures? 5. Do high temperatures reduce catch per unit effort?
