Behavioral feedbacks between anglers and sportfish are widely recognized to be important in the management of sustainable and economically viable recreational fisheries. Quantifying these feedbacks empirically is difficult. Individual-based modeling has proven to be a powerful tool for assessing ecological processes that are difficult to quantify empirically. We used this computational-modeling form to simulate various assumptions associated with fishery-induced behavioral changes within an exploited fish population. We parameterized the angler agents using empirically collected, intensive creel survey data from a new reservoir in Eastern Nebraska. These simulations result in robust-emergent relationships, over many model iterations, between empirically represented anglers and hypothetical sportfish.  This provides a theoretical framework for in situ assessments of behavioral feedbacks between anglers and sportfish.
