Correlation Of Hook-And-Line Vulnerability Of Largemouth Bass (Micropterus Salmoides) With Selected Physicochemical Parameters At Ridge Lake, Dale P. Burkett
Masters Theses
Fluctuation in kilograms of largemouth bass caught per man-hour of fishing pressure (catch rate) in Ridge Lake (a 6.8ha impoundment located in Fox Ridge State Park, Coles County, Illinois) was positively correlated with dissolved oxygen concentration (r=0.7490), conductivity (r=0.7439), pH (r=0.5965), and alkalinity (r=0.7531). Negative correlations were found between largemouth bass catch rate and turbidity (r=-0.5145), as well as ammonia (r=-0.4694). No significant (p<0.05) correlations were found between catch rate and column water temperature, air temperature, barometric pressure, water level, maximum water temperature, minimum water temperature, maximum air temperature, or minimum air temperature.
Models describing the relationships of the most significant physicochemical parameters to catch rate of largemouth bass were chosen to represent the effects of environment …
