Jack Crevalle: A Proactive Approach for Underappreciated Fish

The Guide Post

Dr. Marcus Drymon, a fisheries ecologist at Mississippi State University, highlights his research on an underappreciated fish species, the Jack Crevalle. Supported by organizations like the Lower Keys Guide Association and Bajio Sunglasses, this project focuses on the biology and management of an amazing species. Initially starting as a side project, Dr. Drymon’s interest in the Jack Crevalle grew after realizing its ecological and recreational importance. His research has centered around understanding the fish’s age structure, diet, and movement patterns, often using tagging and telemetry methods. The study reveals that the Jack Crevalle plays a crucial role in coastal ecosystems, but their population in some areas, like the Florida Keys, is declining due to factors like overfishing, prey loss, and habitat changes. Dr. Drymon emphasizes the need for proactive conservation efforts for Jack Crevalle, highlighting their importance to both recreational fishing and ecosystem health. He advocates for more research on their movements, suggesting that healthy populations in some areas, like Mobile Bay, might help replenish declining stocks elsewhere. Additionally, he has worked to promote catch-and-release practices to reduce unnecessary fish kills during fishing tournaments. He also encourages greater cooperation among scientists, anglers, and policymakers to protect this species and ensure its sustainability for future generations.
