Research Interests

My general interests are in quantitative fisheries management and ecology. I am specifically interested in the management of exploited fish populations and I have studied sport fish population dynamics in Lentic and Lotic environments. I am particularly interested in applying Bayesian modeling techniques to address practical fisheries management objectives.

Lake Michigan Yellow Perch - The Yellow Perch Perca flavescens has a long history as an important sport and commercial species in Indiana waters of Lake Michigan. The Yellow Perch population has undergone wide fluctuations in the past and in Indiana, it has been at a very low density since the early 1990s following a precipitous decline from peak abundance in the mid-1980s. Beginning in 1995, the Indiana Department of Natural Resources (IDNR) imposed quota restrictions on commercial fishermen in an attempt to conserve and rebuild the failing stock. In 1997, commercial fishing for Yellow Perch was closed and a daily creel limit of 15 was imposed on sport anglers as the population continued to show no signs of recovery. These harvest restrictions remain in effect at of this writing. Our work provides the Indiana Department of Natural Resources with the information necessary to make informed management decisions.

Figure 2. Yield (kg) estimates of Walleye constructed from the yield-per-recruit model under conditional mortality rates ranging from 0.05 to 0.75 and minimum harvest length limits ranging from 203 to 508 mm and based on (A) conditional natural mortality estimated from the data, (B) conditional natural mortality fixed at 0.20, and (C) conditional natural mortality fixed at 0.50. Error bars represent 95% credible intervals.

Yield-per-recruit modeling of two piscivores in a Midwestern reservoir: A Bayesian approach - Walleye Sander vitreus and hybrid striped bass Morone chrysops x M. saxatilis fisheries are supported by annual stockings in many Midwestern reservoirs. Fisheries managers can modify length limits or bag limits to maximize yield of these species. Yield-per-recruit models are used to evaluate expected yield and assist managers to determine which regulation to implement. However, yield-per-recruit models are typically formulated with point estimates of life history parameters, which ignore uncertainty. Our objective was to estimate yield from yield-per-recruit models of Walleye and hybrid striped bass under variable harvest strategies (e.g., variable minimum length limits and conditional fishing mortality rates) and three levels of conditional natural mortality (cm = estimated natural mortality, cm = 0.20, and cm = 0.50) while incorporating uncertainty from the input model parameters. We estimated parameters of age and growth, mortality, and weight-length models simultaneously using Bayesian inference. The full posterior distribution of these model parameter estimates were then used to estimate yield. Yield estimates of both species were sensitive to specification of conditional natural mortality. Specifically, we found yield was different among length limits for both species at high conditional fishing mortality rates when natural mortality was set at estimated values. We also found yield decreased with both species as minimum length limits increased with high conditional natural mortality (cm = 0.50) and low conditional fishing mortality.

Figure 3. Probability profiles of achieving 80% maximum yield of Walleye under conditional mortality rates ranging from 0.05 to 0.75 and minimum length limits ranging from 254 to 508 mm. Maximum yield based on 406 mm minimum length limit and conditional fishing mortality of 0.70. The probability of achieving 80% maximum yield with a minimum length limit of 203 mm was estimated but results were < 0.001 for all conditional fishing mortality and thus are not included here.

Finally, we presented a probabilistic framework to determine how changing minimum length limits and conditional fishing mortality affects the probability of achieving 80% of the maximum yield. Our results provide insight on the expected yield under different minimum length limits and bag limits while incorporating uncertainty in the model inputs and adds to the sparse literature on hybrid striped bass population dynamics.
