Two Studies by DNR Scientists Highlight Spawning Challenges for Striped Bass in Chesapeake Bay

Two recent studies by Maryland Department of Natural Resources scientists highlight spawning challenges that striped bass, also known locally as rockfish, face in the Chesapeake Bay. The research was published in “Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science” in late 2023 for the journal’s striped bass themed issue. Jim Uphoff, a DNR fisheries biologist, authored a paper that uses long-term datasets to bring a new perspective to the history of the striped bass stock collapse and rebound in the last decades of the 20th century. Angela Giuliano, also a DNR fisheries biologist, published a study that looks at the effects of warming water temperatures in the Chesapeake Bay on the timing and length of the striped bass spawning season. “These studies are important contributions to our existing body of knowledge about striped bass,” said DNR Fishing and Boating Services Director Lynn Waller Fegley. “With the recent below-average spawns, it’s critical that we have as much information as we can on striped bass reproduction and habitat. DNR biologists are adding to the scientific understanding of striped bass recruitment that will help manage this population.” After five consecutive years of below-average spawning success in Maryland’s four major spawning rivers, the Maryland General Assembly’s Joint Committee on […]
