How many fish or kinds of marine life do you think live in the Hudson River? There’s believed to be more than 200 different species, but to be sure someone’s got to count them. No, we’re not kidding.

This Saturday, the New York State Department of Environmental Conservation invites you and your family to be a part of the Great Hudson River Fish Count for the seventh year. But, before you think they are completely crazy, they aren't asking you to try to count the number of fish you see, but rather how many different species you can find.

Everyone is invited to join with naturalists from Albany to New York City as they conduct the count at various sites all along the Hudson River. In order to do this, they will be pulling 30-feet nets through the water and then looking for any water-life caught in the net. Participants can also use minnow traps or rods and reels. All fish will be returned to the river after everyone who is participating has a chance to see them.

The NYSDEC is also encouraging everyone to use #hudsonriverfishcount when you post your pics to social media. There are several places in the Hudson Valley to participate including Long Dock Park in Beacon, Waryas Park in Poughkeepsie, Norrie Point in Staatsburg, and more.
