KEANSBURG, N.J. (CBSNewYork/AP) — Crews have finished removing more than a million dead fish that recently appeared near a Jersey Shore town.

Public works crews on Thursday morning picked up the last of the peanut bunker fish that washed on shore at the Waackaack Creek, Keansburg Mayor George Hoff told

State environmental officials raised the estimate of dead fish from hundreds of thousands to more than a million. They say the scores of fish were likely chased into the Raritan Bay by other fish. Once there, they apparently were killed off by low levels of dissolved oxygen in the water.

The highest numbers have been found in the Waackaack Creek. They also have shown up in Natco Lake and Thornes Creek.

Crews will take the dead fish to the Monmouth County landfill.

The Department of Environmental Protection said there was a smaller fish die-off last week and one last year, but residents said they have never seen anything like the one on Tuesday.
