Last week, Conserve Wildlife joined the American Littoral Society at their annual Parade of Boats event in conjunction with the Operation Oyster program.
Conserve Wildlife, through funding from NOAA’s Marine Debris Program, has spent the last several years in a related effort to clean up Barnegat Bay. Removing derelict crab traps or ghost pots from the bay has been an ongoing initiative. Ghost pots are lost in a variety of ways including improper rigging to buoys and buoy lines cut by passing boat traffic.
The issue spans not only the commercial crabbing industry, but the recreational industry as well. The longer the pots sit on the bottom of the bay the more likely they are to serve as a deathtrap for a variety of marine species. The more marine life that becomes trapped the more the pots continue to attract other marine life. This is of particular concern for Northern Diamondback Terrapins that frequently investigate these pots looking for a quick meal only to be trapped and quickly drown.

With the stopover period winding down, we can say the red knot and other shorebird species left the bay in better condition than the disastrous condition of last year. So what does it mean?
First, the last four years have been a sort of ecological roulette for the birds. Horseshoe crab numbers remained at only 1/3 the potential population possible on Delaware Bay leaving birds at the mercy of good conditions to get enough eggs. Last year, water temperatures stayed low during the mid-May depressing the spawn and the density of eggs. Although the average was 8000-eggs/square meter, there were less than 2000 eggs/ meters square in the month of May. Continue reading “Birds in better condition than last year but still face an ecological roulette”
The best news is a direct consequence of these good conditions, the number of knots and turnstones increased this year. Our season-high estimates show that there are 34,500 knots in the bay and 21,000 ruddy turnstones. These may be the highest counts on the bay in at least 15 years.
Why? At first one would conclude the increased numbers on the bay represent a real increase in the size of the population, but it is not. Shorebirds need time to respond to improving conditions because they are relatively slow breeders, as are most Arctic breeders. Knot numbers on Delaware Bay basically depend on the availability of crab eggs. In bad years, numbers go down because birds come to the bay and leave quickly. Continue reading “Good horseshoe crab egg densities draw 34,500 Red Knots to the bay”
The horseshoe crabs extended their breeding period into the neap tide phase after the cold weather of mid-May decreased water temperature during the spring tides. The crabs roughly require a water temperature of about 59 degrees F before breeding begins in earnest. Crabs still breed at a lower temperature, but many more will breed above the temperature threshold.
At the same time, crabs also look for spring tides, the higher high tides that come with full and new moons, because they can breed in sandy places unavailable at lower tides. This year the water cooled during the new moon spring tide and warmed in the neap. Good spawning during the neap tides of the last week was welcome good news. This May good spawning conditions will raise average egg densities about 50% higher than last year. Continue reading “Horseshoe crabs expanded breeding into neap tides”

Giving kids a head start in learning about nature is the point of Head Start Terrapins, a school course started by the Ocean County MATES program and Conserve Wildlife Foundation of New Jersey. Last October, Ben Wurst, CWFNJ project manager for Bass River and Balanger Creek, picked up seven quarter-sized baby diamondback terrapins from the roadside on Great Bay Boulevard, Little Egg Harbor Township.
Crabbing has been an annual tradition of residents and visitors to the Barnegat Bay region. Yet when those crab pots are abandoned or adrift, they can become death traps for local wildlife, including at-risk species like diamondback terrapin.
Conserve Wildlife Foundation’s new video “Fishing for a Cleaner Barnegat Bay” details this complex ecological challenge. Produced by Citizen Racecar, the video is now available to the public here.
Due to a passing boat, a storm, or simply forgetfulness, abandoned “ghost” crab pots litter Barnegat Bay, continuing to catch crabs and fish. Worst of all is that when animals get stuck in a crab pot, they attract more animals, which in turn also are trapped. Each animal caught acts as bait for new animals to come along.
Some fish species that get caught are blackfish and sea bass. And since the crab pots are just lying at the bottom of the Bay, they do not get emptied out. As a result, any fish that get caught in the crab pots can’t escape and end up starving to death.
Some bycatch findings in retrieved crab pots
Fish are not the only victims of the crab pot death traps – the famous diamondback terrapin, a turtle species that is currently experiencing an alarming population decline rate, also is a common victim of being trapped by abandoned crab pots. One crab trap has even been found to contain 17 dead terrapins.
Fortunately, there is a solution to this problem, as described in the video. Conserve Wildlife Foundation, supported by the National Oceanic and Atmospheric Association’s Marine Debris Removal Program, is tackling the problem directly by finding and removing abandoned crab pots from the water. GPS grid and SONAR imagery from Stockton State University allows recovery teams to find exactly where the crab pots are located. Low-cost SONAR devices can even be used by well-trained fishermen to find their own crab pots merely days after losing them.
Over 1,300 abandoned crab traps were picked up by the program in Barnegat Bay over the past two winters. Ultimately, the metal used in the crab traps is either recycled or used to create energy by corporate partners Covanta and Schnitzer Steel.
“This is a true environmental success story because it addresses a serious ecological problem by creating ecological and economic benefits for the good of the greater Barnegat Bay community,” says CWF Executive Director David Wheeler. “Thanks to local fishermen and volunteer students, removing these death traps has prevented countless at-risk diamondback terrapins and other species from drowning unnecessarily. It also has strengthened public safety by removing navigational hazards from the bay.”
In addition to NOAA’s support for the project, the video was made possible by funding from the New Jersey Corporate Wetlands Restoration Partnership. Other project partners and supporters include the Marine Academy of Technology and Environmental Science – Ocean County Vocational Technical School, Stockton University, Monmouth University, American Littoral Society, Covanta, and ReClam the Bay.

Two volunteer groups and the Seaside Heights public works department teamed to help a baby osprey that had a balloon ribbon tangled around its leg in a nest at Island Beach State Park.
A peregrine falcon chick is shown after it was removed from its nest for banding.
Several scientists, protected by the curious combination of an umbrella, a duster and a hard hat, scrambled across the roof of a Jersey City high-rise this week to fend off the fierce attack of two adult peregrine falcons.
The scientists were there to briefly retrieve three falcon chicks from a nest box 42 floors above the city streets, so they could weigh, measure and band the birds before returning them.
The three chicks, still covered in fluffy white down, are the latest additions to a growing population in New Jersey of the world’s fastest animal.
NJDEP’s 9th BARNEGAT BAY BLITZ SET FOR FRIDAY, JUNE 8, 2018
by Erin Conversano, CWF Intern
Would you like to help restore the health of Barnegat Bay’s ecosystem? You can participate in a day of action for the Bay! The New Jersey Department of Environmental Protection (DEP) will be hosting its next Barnegat Bay Blitz clean-up day on Friday, June 8.
Join Conserve Wildlife Foundation and hundreds of other volunteers across the watershed, which includes all of Ocean County and parts of Monmouth County, in helping to clean up the Barnegat Bay Watershed and spread awareness about pollution that impacts the Bay. Clean-up events are happening all throughout the watershed!
To register for a clean-up, visit the DEP’s website.
Barnegat Blitz highlights include:
31,582 volunteers
4,579 cubic yards of trash and recyclables cleaned up
37 municipal partners
20 corporate and nonprofit partners
2 llamas that help haul out the trash collected by volunteers
In the middle of Barnegat Bay, there are many small islands called Sedges. These islands are home to a number of species of plants and animals, but unfortunately are impacted by litter that the tide washes in. Volunteers by boat, kayak and standup paddle board will make their way out to many of these islands, including Island Beach State Park, Seaside Heights and Brick to sweep them clean of debris. Get involved!
It’s not just the bayfront communities that impact Barnegat Bay. Communities miles and miles inland also play a role. After all, we are all downstream! That is why at the Barnegat Bay Blitz, volunteers will work to clean up all over the watershed, from inland areas of Plumsted to the barrier islands. In Plumsted, a farming community, volunteers include more than just people! Llamas will also join the crew to help haul out trash and debris that volunteers collect from the Colliers Mills Wildlife Management area. To make friends with llamas, register for the Plumsted clean-up on DEP’s website.
Andrew Drummond captured this image of “Harmony 2” on Memorial Day in Marlboro, VT. She was banded as D/64 and outfitted with a transmitter May 29th, 2012 at Merrill Creek, Warren County. We have since been following her movements on Eagle Trax. She fledged in 2012 and spent her first winter on the lower Chesapeake Bay before traveling to Maine. She has spent the last five years in a 100-mile swath of western Connecticut and Massachusetts, and now into southern Vermont. She is of breeding age so we suspect that she will be nesting in the area next season.
