Dead fish at the Navesink River Rowing facility in Red Bank in 2015. Another widespread die-off of menhaden, or bunker fish, has been underway in the river in recent days, and the New Jersey Department of Environmental Protection is investigating, according to a report by NJ.com.
Similar incidents in recent years have been attributed to a natural phenomenon: bunker being driven upriver by hungry bluefish, a predator, into shallower water, where there’s less oxygen.
