Abstract
Total hours fishermen spend fishing and total amount of fish harvested per year are some of the most important pieces of knowledge gained from creel surveys. They provide crucial information that assesses fisheries mortality and pressure. MN DNR uses their results from creel surveys to improve or impose regulations, and to maintain healthy fisheries. Based on results from similar studies, there is expected to be a positive relationship between hours fished and fish harvested. To determine the relationship between these two variables on Upper Red Lake, data from two years were selected when the variables were at their highest and lowest values, without regulation changes occurring. The results from this study were obtained using regression analysis on catch rates. The values from the catch rate analysis showed that fish per angler hour is dependent on the amount of effort put forth, but there are ultimately other variables influencing the overall outcome. This study could be expanded in the future to include questions regarding why anglers exhibit patterns of pressure in specific systems.
