Seth Green (March 19, 1817 – August 18, 1888) was an American pioneer in fish farming (pisciculture and aquaculture). He established the first fish hatchery in the United States in the Town of Caledonia, New York. He was a successful commercial fisherman, operating a large and profitable fish and game market in Rochester, New York. After many years of operating his commercial hatchery in Caledonia, he entered government service with the New York State Fish Commission and eventually became Superintendent of Fisheries for the state of New York. Seth Green's pioneering efforts to raise fish stocks and restore fish populations for sporting purposes established a standard of aquaculture recognized internationally. He is commonly referred to as the "Father of fish culture in North America."
