Maine fishery regulators have begun implementing scallop fishing closures to try to protect the population of the valuable shellfish.

Maine’s winter scallop fishery is one of the most lucrative in the state. The state uses localized fishing closures to allow young scallops to grow to maturity.

The closures that went into effect this week apply to the Englishman Bay, Addison, Isle au Haut and Swans Island areas.

Maine scallops have been worth more than $10 per pound at the docks in every year since 2012. They’re prized in the culinary world.
