Breeding of strawberries in water where other fish would freeze to death but, with a special gene that allows it to produce a sort of anti-freeze, it can survive. This gene is put into a bacteria that is sprayed on the strawberry during the freezing temperatures, allowing it to also be resistant to cold. The strawberry is then cleaned, removing the bacteria. Breeding of strawberries The breeding of strawberries is a long story that starts with the selection and cultivation of European strawberry species in western Europe in the 15th century while a similar discovery and cultivation occurred in Chile.

Commercial butterfly breeding biological pest control. Captive breeders employ cost-effective and sustainable methods of plant propagation needed to provide larval food for their stock. Green houses, hydroponics, drip irrigation, and organic-based methods are used to control disease costs and create high plant yields. Pesticides are not used in the breeding of stock. Captive breeders reduce the exposure of laboratory bred stock to naturally curing predators, parasites and diseases that occur in wild stock by rearing butterflies in enclosed environments. The butterfly and moth larvae are typically raised in containers in various densities dependent upon the predetermined protocols. Some butterfly larvae best raised in
