From 1988 to 2013 The River Project caught and identified 50 species of fish in the lower Hudson River at Hudson River Park. In 2007, we moved approximately .5 miles up river to Pier 40 where we continue to gather data on local fish populations.

Below is a list of all fish species collected at Hudson River Park. The 50 species identified, represent 42 genera, 33 families, and 15 orders of fishes. Fish were caught using passive trapping techniques (traps suspended to hang just off the bottom of the river). Any fish caught by other methods are referenced at the bottom of the list.
