Seth Green (pisciculture) Seth Green (pisciculture) 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 also a successful commercial fisherman, operating a large and profitable fish and game market in Rochester, New York, and fishing in Lake Ontario. 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.

Plant breeding similar to the favored parent as possible. Returning to the example of the mildew resistant pea being crossed with a high-yielding but susceptible pea, to make the mildew resistant progeny of the cross most like the high-yielding parent, the progeny will be crossed back to that parent for several generations (See backcrossing ). This process removes most of the genetic contribution of the mildew resistant parent. Classical breeding is therefore a cyclical process. With classical breeding techniques, the breeder does not know exactly what genes have been introduced to the new cultivars. Some scientists therefore argue that plants produced by
