Every November The River Project closes its Wetlab aquarium for the fall/winter season. Release of the Fishes marks this with a free open house party. The marine animals are released back to the Hudson River by kids, and there are exhibits, arts and crafts, refreshments and a raffle. Staff and volunteers provide insightful tours of the Wetlab to show the vibrant ecosystem of the New York Harbor estuary. There will be a microscopy station and a touch tank where kids of all ages can connect with crabs, snails and other critters. This is a free event with a $10 suggested donation.
