His work and contributions to fish culture were recognized in both the U.S. and abroad. In 1872 and 1875 the of France awarded Green solid gold medals for his work in pisciculture. In 1876, the U.S. Centennial Commission gave Seth Green a certificate of award at the International Exhibition held at Philadelphia. In 1880, the in Berlin awarded Green a gold medal for his work in fish culture. In 1882 Green was on a fishing trip off the coast of the Carolinas
Captive breeding artificial insemination procedure. Furthermore, this approach yields lower-quality semen, because shipping requires extending the life of the sperm for the transit time. There are regional programmes for the conservation of endangered species: The objective of many captive populations is to hold similar levels of genetic diversity to what is found in wild populations. As captive populations are usually small and maintained in artificial environments, genetics factors such as adaptation, inbreeding and loss of diversity can be a major concern. Adaptive differences between plant and animal populations arise due to variations in environmental pressures. In the case of captive breeding prior
