Right Whale Count Rises to 384, Threats Persist

The critically endangered North Atlantic right whale population rose to an estimated 384 animals in 2024, up eight from a revised 2023 estimate of 376, marking a fourth consecutive year of slow growth. Scientists from the New England Aquarium, NOAA and the North Atlantic Right Whale Consortium credit conservation and new management measures — including Canadian protections, seasonal fishing closures and vessel speed limits — for helping the modest rebound. Despite cautious optimism, the species remains at high risk from entanglement in fishing gear, ship strikes, climate-driven prey shifts that depressed reproduction, and low calf counts (just 11 calves in 2024). Researchers reported fewer entanglements and ship strikes this year and shorter intervals between births for repeat mothers, but protections have imposed burdens on coastal fisheries — especially Maine’s lobster industry — and proposed legislative changes could delay some measures. Experts warn continued and strengthened protections are essential because a rapid habitat shift into busy shipping areas could quickly reverse recent gains.
