Among vertebrates, most of the fishes are unique for the lack of acrosome in their spermatozoa. The sperm enters the egg through micropyle of the egg. This has facilitated heterologous fertilization in many fishes and led to hybridization and polyploidization. Hybridization is performed both in the nature and domesticated fishes. Today, some of the hybrids have high growth rate than their parents so artificial hybridization be carried out among some economic species. Some of hybrids have high similarity to their parents, so identification and verification of hybrids is impossible. This identification needs both phenotypic (morphometric and meristic) traits and molecular analysis in compared with parents. In this case, the most confidence and the quickest method are molecular markers based on DNA, especially microsatellite markers. It could play an important role in the precise confirmation of fish hybrids.
