The NJDEP Division of Fish and Wildlife has deployed 7 acoustic receivers in Delaware Bay to track migration patterns of Atlantic sturgeon. With the recent endangered species listing of Atlantic sturgeon, effective April 6, 2012, research on this species has gained significance.
The receivers are generally set in water depths less than 20 feet. Those fishing in inshore waters may encounter the white buoys marked "NJDEP Research" which should be avoided.
