I copied this from the NY DEC web site. These are the Bowfishing regulations for New York State.

Bowfishing
Any person who has a fishing license or a small game hunting license or is entitled to fish without a license may take carp of any size and in any number by longbow from May 15 through September 30 from any water of the State where fishing and the discharge of a bow is permitted. Taking fish by bow is otherwise prohibited.
