This is the earliest the Wreck Pond team has caught river herring in their net. The species is typically observed once water temperatures are between 42 to 50 degrees Fahrenheit but ocean temperatures have been hovering around 40 degrees and we did not anticipate seeing any herring yet. At the time of capture, the temperature in the pond was recorded at 47 degrees Fahrenheit (39 degrees offshore). We will continue to monitor offshore buoy readings but it would appear that the herring can and do come into Wreck Pond when it is a bit colder offshore. One helpful hint regarding their potential presence close to shore are plunging Northern Gannets observed out at sea. Even though these birds are most likely feeding on bunker, it does make us wonder if schools of herring are mixed in as well.

With the upcoming Nor'easter expected to hit tonight through Saturday morning, the team is curious to see if more herring show up in the net pushed by the winds and exceptionally high tides associated with such a storm. We hope to brave the storm and continue sampling through Saturday, but if the orange buoy is gone, that means we either headed for higher ground or we lost our gear. See you after the storm!

While for most, the warm days earlier this week probably brought thoughts of sunny spring days spent at the beach or the park, but for us here at the Littoral Society, the warm days brought thoughts of one thing: river herring. River herring migrate into freshwater to spawn in early spring, with the start of their migration triggered by warming ocean temperatures. In anticipation of the herring run into Wreck Pond, we spent the past week installing antennas in the watershed. These antennas are used to track the movement of river herring previously tagged with passive integrated transponder (PIT) tags. Like a fish EZpass, when a tagged fish swims through or past an antenna, its tag number is registered on a computer along with the date and time. Our tagging work has already provided some interesting information on the alewives spawning in Wreck Pond: data indicate spawning alewives spend about 20-30 days in Wreck Pond, and are most active at night. In addition, two fish (Samantha and Bonnie) have been recorded spawning in Wreck Pond in multiple years.
​
Next week we will be starting our fish sampling. Using a fyke net, we hope to capture adult river herring migrating into Wreck Pond to spawn. We also record information on all other species we catch. If you have an interest in helping to sample, contact Zack at Zack@littoralsociety.org. Stay tuned the next several weeks for more updates on this year’s monitoring.
​

Earlier this month we held a luncheon for our citizen scientists to thank them for all the hard work they had done the previous year. During the lunch, Society staff updated the attendees on the status of the Wreck Pond work and how the data collected in the citizen science program is helping to improve our understanding of Wreck Pond and our restoration work. Delicious sandwiches were provided by Bing’s Beach House Deli in Avon. In addition to the bird and site monitoring, we plan to expand the program this year to include plant monitoring and trail cam surveys. If you have interest in becoming a citizen scientist, please contact Julie at Julie@littoralsociety.org.

Sampling events are open to the public, but the total number of participants per event is limited. If interested, please contact Julie Schumacher, Julie@littoralsociety.org or Zack Royle, zack@littoralsociety.org for more information on sampling dates and availability.  

October 13, 2017. Friday the 13th. A most portentous day in a most ominous month. Who knew what awaited Society staff and volunteers as they set out to once again sample Wreck Pond? Was some dark menace looming in the depths of the pond ready to snatch up would be seiners? Were the ghosts of a hundred Atlantic silversides lost in seine nets of past waiting to rise up and enact their revenge? There was only one way to tell. The Wreck Pond faithful steeled themselves against the ill-omen in the air, and waded into the cool pond waters…

…and caught some really interesting fish!  As always, we caught an abundance of Atlantic silversides; however, mixed in the bunch (and, if not careful, easily missed because of their similar appearance) were a number of bay anchovies. We also caught stripped killifish, northern kingfish, white mullet, and several large snapper bluefish. Remarkably, we also caught one juvenile weakfish (​Cynoscion regalis​). This marks our first catch of a weakfish in Wreck Pond since we began sampling three years ago.
​
Weakfish were once an abundant and popular commercial and recreation fish along the coast of NJ and in the Delaware Bay. Overfishing occurred in the 1970s and 80s and regulations were passed in the 1990s and 2000s to reduce fishing pressure and restore stocks. Unfortunately, the population has yet to rebound to its historic levels due to natural mortality from predation, competition, and changes in the environment. Weakfish are preyed upon by striped bass and spiny dogfish, they compete with Atlantic croaker, and warming waters and reduced prey species such as bay anchovy are all likely contributing to high weakfish mortality.

On October 6, 2017, Littoral Society staff and volunteers completed another seining event at Wreck Pond. While we did not match the excitement of last week’s sample (4 juvenile alewife caught!), we did catch a good number of species. As always, we hauled in hundreds of Atlantic silversides, as well as many northern kingfish. One mullet was caught on the Sea Girt side of the pond, along with several striped killifish. We also observed signs of “snapper” bluefish chasing and feeding on bait fish at the pond side culvert entrance, a common site the past few weeks.

The search for juvenile river herring is underway at Wreck Pond. American Littoral Society staff along with volunteers began the 2017 summer/fall fish sampling earlier this month and will be conducting sampling events weekly until October.

On August 21, Society staff with help from up and coming young biologists, were at Wreck Pond for the Great American Solar Eclipse. Seine pulls were made earlier that morning as well as during the climax of coverage during the eclipse to document if there was any differences. 

Although many of the same  species were caught at both times, staff did notice a substantial increase in the amount of Northern kingfish during the eclipse.  

If you are interested in volunteering for upcoming fish sampling events, please contact Zack Royle, zack@littoralsociety.org

The Wreck Pond team was happy to conclude another year of school outreach with successful field visits from Communications High School. Over the course of two days, 80 freshman from the vocational school enjoyed  participating in scientific field work stations including: seining & fish sampling, macro invertebrates, water quality, citizen scientist monitoring, and nature walks. An exciting find during these trips was the first documented juvenile river herring of the year,  presumed to be an Alewife! That means adults successfully spawned this year helping the Wreck Pond Alewife population to grow.

In total, American Littoral Society staff and volunteers welcomed nearly 200 students in 2017 from schools in the Wreck Pond watershed to enjoy a day of interactive field activities to further connect them to their surrounding environment. For more information on how to get students involved with the Wreck Pond project, please contact Julie Schumacher, Julie@littoralsociety.org
