Emergency Shellfish Closures in Harpswell and Brunswick Due to Algae Bloom
What happened
State regulators enacted emergency harvesting closures in Harpswell and Brunswick following a softshell clam die-off linked to an ongoing harmful algal bloom. The Maine Department of Marine Resources halted picking shellfish in Maquoit Bay and part of Middle Bay. In Brunswick, town officials reported that 80% of adult clams were stressed, dying, or already dead. The closures are intended to protect remaining juvenile clams from additional disturbance.

Why it matters
Brunswick was the largest softshell clam port in Maine in 2025, where harvesters pulled in almost $1.8 million worth of clams. The closures immediately halt harvesting in the affected bays. The department's stated goal is to allow surviving clams to provide seed for future harvests.
