PORTLAND, Maine (AP) — America’s lobster fishing business dipped in catch while grappling with challenges including a changing ocean environment and new rules designed to protect rare whales.

Members of the industry say they face existential threats from proposed rules intended to protect the North Atlantic right whale and climate change that is influencing where lobsters can be trapped.

Data released Friday say Maine fishermen’s catch of 93.7 million pounds in 2023 was 5% less than the year that preceded it and the lowest total catch since 2009.
