Why Fish Are Dying In The Hudson River

There have been numerous reports of dead fish floating in the Hudson River and littering the banks of the shore from Haverstraw Bay south to the New York Harbor. Many fisherman and residents have been reporting these swaths of dead fish to Riverkeeper who states that most of these fish are Atlantic Menhaden or “Bunkers” as most often referred to by Fisherman, but other fish may be affected.

According to Riverkeeper, the problem is that the fish are suffocating. When we have long stretches of hot weather, coupled with less than normal rainfall and other factors mixed in, such as algae growth, these conditions can reduce the levels of oxygen in the water which ultimately will suffocate fish. Warmer water already carries a lower oxygen level than cooler water. Some, such as the Atlantic Menhaden, are more prone than others to this fluctuation of oxygen.

“Importantly, it’s a symptom of a compromised and fragile ecosystem in the river and harbor. It’s yet another warning about our need to restore the river to health and balance in the face of climate change.” -Riverkeeper

“Sewage pollution and fertilizer act as “nutrients” that fertilize phytoplankton and spur algae growth. Scientists have determined that the Hudson is the most “nutrient rich” estuary on earth. Sewage treatment plants take out some nutrients, but not all.” – Riverkeeper
