About Mackenzie

Mazur's research focuses on fisheries science and management. Mazur's overarching themes in writings include fisheries, fisheries modelling, fisheries management, conservation, and fish population dynamics. Mazur more specifically, uses computer simulations to evaluate management regulations in New England fisheries. Mazur's other areas of expertise also include fisheries stock assessment, habitat modelling, and oral history interviews. Mazur is the president of the American Fisheries Society Socioeconomics Section, and serves on the Ocean Best Practices Ethics Working Group and the Gulf of Maine Research Institute Science Seminar Committee.

"Contributions of a Conservation Measure That Protects the Spawning Stock to Drastic Increases in the Gulf of Maine American Lobster Fishery" (with Bai Li, Jui-Han Chang, and Yong Chen). Marine Ecology Progress Series 631 (2019): :127-139.

Discussing V-notching, a conservation measure intended for the protection of mature female lobsters, which has been hypothesized to have contributed to the dramatic increase in American lobster Homarus americanus landings and stock biomass in the Gulf of Maine. Evaluates the impact of this conservation measure, along with scenarios examining different v-notching compliance rates and v-notch definitions which were simulated using an individual-based lobster simulator with different recruitment dynamics scenarios.

"Using an Individual-Based Model to Simulate the Gulf of Maine American Lobster (Homarus americanus) Fishery and Evaluate the Robustness of Current Management Regulations" (with Bai Li, Jui-Han Chang, and Yong Chen). Canadian Journal of Fisheries and Aquatic Sciences 76, no. 10 (2018).

Aims to modify and parameterize an individual-based lobster simulator (IBLS) to simulate the American lobster fishery in the Gulf of Maine. Describes  that in order to simulate the fishery, the IBLS was tuned to match the seasonal catch and size composition from the 2015 American lobster stock assessment by adjusting the values of coefficients for select parameters. 

"Effects of Increases in Fishery Resource Abundance on Conservation Compliance" (with Teresa R. Johnson). Marine Policy 122 (2020).

Examines conservation compliance in the American lobster fishery in Maine. Explains in this fishery, there is an important conservation measure that protects spawning female lobsters, known as v-notching, which is considered a norm.
