BALTIMORE — A large number of dead fish were discovered floating in Fells Point on Wednesday.
Our crews spotted many of them by the Bond Street Wharf.
Allison Blood, the Environmental Program Manager for Baltimore's Waterfront Partnership, broke down what most likely occurred.
She tells us the fish deaths are most likely caused by reduced oxygen thanks to a number of factors including extreme heat and lack of rain.
The Maryland Department of the Environment (MDE) says there are about 1,000 dead menhaden, 126 dead blue crabs, and small number of other fish species.

"The likely cause of low dissolved oxygen linked to a localized 'Pistachio Tide' event— an algal bloom that creates green surface sheen and produces a sulfur odor as it decomposes, depleting oxygen in the water," MDE tweeted.
There was also a fish kill in the Potomac River over the weekend but the cause of that event was likely due to high water temperatures and reduced river flow.
This isn't the first time such sightings have been reported downtown.
In September 2025, more than 25,000 fish died along the Baltimore Waterfront Promenade closest to Aliceanna Street.
