From Maine Lobster Population Declines Sharply in Midcoast Region

How could the decline in the Midcoast lobster population affect Brunswick?

Possible What happens if… A possibility worth considering, not a forecast.

Midcoast lobster decline may reduce revenue for Brunswick's fishing community The study found that the Midcoast lobster population, which includes Brunswick, is experiencing a sharp decline, evidenced by an 80% drop in baby lobsters between 2010 and 2022. This shortage of the smallest lobsters is shown to work its way through the population, resulting in a 50% decrease in adults large enough for fishermen to catch. Since the local economy relies heavily on the fishery, fewer available adults could ultimately mean reduced catches and lower revenue for the community.

Why it matters

The lobster fishery is a cornerstone of the Maine economy, generating over $461 million in landings in 2025. For communities like Brunswick, which are situated in the Midcoast region, the health of this resource is critical to local employment and revenue streams. The study highlights that the decline is not just a temporary fluctuation but a systemic issue linked to environmental changes.

The decline is attributed partly to warmer water temperatures, which are changing where lobsters can live. This shift, combined with the fact that the Midcoast region recorded the steepest declines in the Gulf of Maine, suggests that the entire regional ecosystem is under pressure. The findings reinforce the need for continuous monitoring to understand how these environmental changes will shape the fishery years later.

What we don't know yet

  • Will warmer water temperatures continue to drive lobsters into deeper, harder-to-track habitats?
  • What specific interventions could stabilize the lobster population in the Midcoast region?

What would change this answer

Warming water temperatures accelerateThe decline in adult lobsters could become stronger and faster, leading to more immediate economic strain on Brunswick.
Sampling efforts expand significantly in Down East MaineResearchers may gain a clearer picture of population distribution, which could help determine if the decline is due to reduced abundance or simply dispersal.
