Why it matters
This is the conservation issue most directly shaping modern lobster gear rules. Vertical line reduction, closures, weak links, and on-demand gear all stem from the need to reduce entanglement risk.
Right Whale Entanglement
Injury or death caused when North Atlantic right whales become wrapped in fishing rope, especially vertical lines from fixed gear.
Definition
Right whale entanglement is the term used when fishing rope wraps around a whale’s mouth, flippers, tail, or body and causes drag, wounds, or fatal injury.
Conservation impact
NOAA reports that over 85 percent of right whales have been entangled at least once, and only about 70 reproductively active females remain. That means lobster management now has to solve for both fishery continuity and whale recovery at the same time.
Quick facts
- Population context
- 384 right whales estimated alive at start of 2024
- Entanglement prevalence
- Over 85% estimated entangled at least once
- Primary management response
- Reduce vertical line risk

American lobster conservation faces a pivotal moment: the 2026 ASMFC Benchmark Stock Assessment found the Gulf of Maine/Georges Bank stock has declined 34% since 2018 and overfishing is technically occurring, while southern New England populations remain at record lows. Here is what the science says about the challenges ahead and the conservation strategies that are working.
