Abstract

The cultivation of many economically important species has been helped greatly by the growing use of the technique of artificial fertilization and incubation. The discovery of artificial fertilization is supposed to be very old and this technique is said to have been practiced in the middle ages by the monk Don Pinchon in trout. The rediscovery of wet artificial fertilization in salmonids in 1842 by two anglers Gehin and Remy and the discovery of dry fertilization by the Russian Vrassky and its application between 1856 and 1870 led to great technical progress. Artificial spawning was first achieved in striped mullet in 1930 in Italy. In general the technique of hypophysation has triggered rapid progress in the induced breeding of cultured species, in the controlled rearing of fish larvae and in selective breeding.
