While one way to prove an understanding of environment and environmental education may be a multiple choice exam, the real proof lies in action. In the early days of July the young people that attend the Tremont United Methodist Church Summer Program visited the Bronx River at the Mitsubishi River Walk adjacent to the Bronx Zoo. The goal was to get in a canoe in the Bronx River and learn the basics of paddling. Forty-five youth, thier counselors and their director, Cheryl Holtz Andrews, met their goal with flying colors, paddling until their armswere ready to fall off. But this was just the beginning. Two young lady’s looked around at the river and were not quite satisfied with the experience of canoeing for the first time in their lives.
“Damian, we should do something about all of these plastic bottles floating in the river,” said one.
“Yeah, they could all be recycled,” said the other. And from their they set about making it happen.
Today, after almost two months of convincing their director that it was a necessary event, the two returned with 12 other program participants and once again paddled the river. This time, however, the focus was the removal of any floatable garbage that they could reach safely from their canoes. With dilligence and care (and no lack of joyful enthusiasm) the youth spent over an hour paddling to distinct areas of the river between the Bronx Zoo and The New York Botanical Garden and removing plastic bottles, plastic bags and one large plastic triangle once used as part of a traffic blockade. It was impressive to see the pride with which each successive 
canoe came up on to the bank to show off what they had found in the river, what they had done to improve the environment that surrounds them. If there is a test to discover just what has been internalized from a lesson, this was it.

Wednesday’s visit to Barretto Point Park to provide some waterfront education and canoeing was a great success. We were only there for a couple of hours but more than 20 people were able to canoe in the East River and learn about what lurks beneath the waves.
After a quick seining brought up dozens of silver sides ( thousands escaped), another fish caught my eye. It was a little harder to corral than the silversides, but a concerted effort landed a juvenile flounder (summer flounder?). 
On the bottom of the shore, the camoflague helped the fish absolutely disappear, but in my hand it looks quite alien.

On a visit to Hunts Point Riverside Park, I decided to try my luck in the water with a seine net. I could see the small fish flashing along under the surface, but I was not sure that I would be able to sample any since they seemed to sense my presence well before I approached the river’s edge. But one short walk parallel with the shore brought up the bounty of the sea.
These silversides (maybe Rough Silversides?), also known as sand smelt, are one of the most abundant fishes in our coastal waters. As Tarleton Hoffman Bean in his 1903 work Catalogue of the fishes of New York writes, these fish are not of great importance as a human food source, but they are a food source for the larger fish that inhabit local waters, as well as the wading birds that are regular visitors.
Silversides begin to spawn in May and, after a gestation period of just eight days, their young begin feeding on zooplankton before graduating to detritus, algae and even small fish and insects. The schools follow the tides up the river to feed in the salt marshes or other protected river banks, swimming in tight shoals that serve as a form of protection against predators. Over the summer the populations swell, creating a migrating energy source that will move out to deeper water in the fall, sharing the productivity of the estuary and the salt marsh with the greater oceans.
Unfortunately the picture below did not turn out as planned, but the jellyfish shown, most likely a comb jelly, also came up in my net. One of 90 species in phylum Ctenophora, some are able to glow with a slight phosphorescence as this example shows. The color that appears in the photo was not visible to my eye at the park, but appeared when I cropped the shot. Comb jellies are all carnivores and, though they have no tentacles, have tremendous mouths under their bell and can even eat prey larger than themselves.
