Phytoplankton Bloom Recedes in Casco Bay | Portland Maine News

A harmful phytoplankton bloom caused by Karenia mikimotoi is receding in Casco Bay, Maine, after causing widespread clam and marine life die-offs stretching from the Maine-New Hampshire border to Penobscot Bay. While officials confirm the bloom still poses risks to fish and shellfish, cell counts are trending down — a sign it may be past its peak. Though similar blooms have hit the area before — notably in 2017, which killed lobsters and clams — this one doesn’t threaten human health. The Department of Marine Resources remains vigilant, continuing water sampling and oxygen tests until the bloom fully dissipates.
