Quantitative Fisheries Lab
We conduct scientific research on the dynamics of fish and invertebrate populations, the fisheries that pursue them, and quantitative methods for stock assessment and management decision-making. Some of our current projects involve Gulf of Mexico red snapper, reservoir largemouth bass fisheries in Alabama, trophic interactions and management of small impoundments, assessment of Chinook salmon stocks of western Alaska, Laurentian Great Lakes walleye management, and crayfish population dynamics. We emphasize the development and use of quantitative models to understand the behavior of these complex systems and to support science-based fisheries management. Our projects typically involve a combination of intensive field sampling and data collection efforts with computer estimation and simulation modeling. If this kind of thing interests you, take a look through our recent lab activity posts below, which includes some nice video and photos of field work, and check out the “Opportunities” link on the sidebar to look into joining the lab.

FISH 7540 Quantitative Techniques in Fishery Assessment
When offered: spring semester of odd-numbered years
This graduate-level course aims to acquaint students with essential quantitative and interpretational tools to test hypotheses and make management decisions regarding fish and other aquatic organisms. In particular, students will become familiar with how to harness recent advances in computer speed to allow them to tailor their models to their data rather than vice versa. The course reviews elements of survey design, classical linear models for hypothesis testing, maximum likelihood estimation, and Bayesian analysis. Students will also acquire a working knowledge of the R statistical software program to analyze their data. The course consists of a lecture and laboratory component. The lecture will cover critical concepts in data analysis and modeling whereas the lab will allow student to put what they’ve learned into practice.
FISH 7530 Fish Population Dynamics
When offered: spring semester of even-numbered years
The course explores the fundamental dynamics of fish populations and fisheries with an emphasis on estimation of critical parameters and simulation modelling to forecast management outcomes. Students will learn introductory stock assessment methods and will build computer models to assess fish populations using the open-access program R. The course is intended for graduate students in SFAAS or other natural-resource departments.
Report a Tagged Fish
We are conducting fish tagging studies on red snapper in the Gulf of Mexico and largemouth bass at several lakes in northern Alabama. If you captured a tagged red snapper, please contact us by email at firstname.lastname@example.org or by calling 1-855-818-9983. If you captured a tagged largemouth bass, please contact us by email at email@example.com or calling 1-800-774-2847. After contacting us you will receive further instructions on how to submit your tag to obtain your cash reward. Click the link below for examples of what the tags look like.
