Numerous fish were spotted floating yesterday in the Raritan Bay and its tributaries, according to a release from the NY/NJ Baykeeper.
The organization reported fish kills of peanut bunker in the Leonardo Marina, Thornes Creek, and Natco Lake.
“We have reported these to the state and county officials. The likely cause is low dissolved oxygen, not uncommon for late summer, warm water and lots of nutrients in the water,” the release said.
A subsequent update from the organization stated that dissolved oxygen levels at the Leonardo Marina have improved.
There have been multiple fish kills in New Jersey due to various reasons in the last decade.
In January 2015, more than 5,000 fish died in a discharge canal at the the Oyster Creek nuclear plant in Lacey Township.
At the time, state officials said the Atlantic menhaden, also known as bunker, may be drawn to the canal’s warm water or are scared of a predator.
