joe reynolds 200On Sunday, June 23, 2019 the annual early summer edition of "Seine the Bay Day” event took place at four locations: 1. Cliffwood Beach in Aberdeen Township, 2. the free public beach along Front Street in Union Beach, 3. in the Port Monmouth section of Middletown Township near the mouth of Pews Creek , and 4. near the mouth of Many Mind Creek in Atlantic Highlands.

Volunteers with Save Coastal Wildlife conducted the seining survey. A 50-foot-long seine net with buoys on top and weights on the bottom was hauled through the water and pulled towards shore.

Juvenile bluefish, juvenile herring, bay anchovies, and spearing (Atlantic silversides) were the stars of the show that took place along the southern shore of New York Harbor, downstream from New York City.

Seining is a method of taking the pulse of a local ecosystem. It's a way to gain an insight into the health of the near shore environment where many people swim and enjoy the bay. It’s a chance to see what is living in local waters without harming sea life.

All fishes, crabs, and other aquatic creatures were identified, cataloged, and returned to the water. In addition to seining, water temperature, salinity, and turbidity information were documented by volunteers at each site.

Below are the details of the event. Species found and data collected are listed beneath each seine location.

Thanks and special appreciation goes to volunteers with Save Coastal Wildlife for all their wonderful help and time, especially to Mel, Jen, Ed, Frank, Abby and her dad, and the Sheridan family. No one person can ever seine alone. It’s truly a team effort.
