Fish Situation in Hackensack River

We received several reports of dead fish along the tidal impoundments at DeKorte Park and other shallow areas of the Hackensack River over the weekend.

Unfortunately what happened is not an uncommon, though not every day, occurrence during the summer due to environmental conditions.

When there is a sudden spike in temperatures dissolved oxygen is depleted from the shallow water, which warms up too fast. The fish you saw were mostly White Perch and Menhaden, which are sensitive to these fluctuations.
We appreciate everyone’s concern and reaching out to us. It is important that you, as our eyes and ears over the weekend, let us know of any seemingly unusual conditions.
