Pier 42 Video
In this video, a school of Atlantic silversides (Menidia menidia) can be seen swimming in the piling field along with what appears to be a small juevenille Striped bass (Morone saxatillis). The fish swim near the rubble at the bottom of the river; most likely fallen concrete pier structures. With so much of New York’s shoreline modified from its natural state the rubble can act as habitat for fish and other organisms including red algae, numerous species of fish and invertebrates. One invertebrate, Eastern oysters, Crassostrea virginica, was once a keystone species in New York but its population plummeted by the early 1900’s due to overfishing and pollution. However small populations do remain like the small group roughly 1 min 25 seconds into the video.
