They are used in researches of embryology, enetics, aquatic toxicology, behavioral science and environmental science.Ever since George using experimental gynogenesis method was published in nature in 1981,zebra fish, medaka and other fishes became favorite laboratory animals and played more and more important roles in the studies of genetics and environmental science. In 1990s,Chinese researchers began studying on rare minnow, swordtail, red crucian carp and other fishes as laboratory animals; consequently, a professional subgroup of Chinese Association for Laboratory Animal Sciences named Society of Experimental Aquatic Animal was set up in 2001 to promote researcher in this area. Rare minnow, Gobiocypris rarus , is a small cyprinid fish. Distributing in Hanyuan, Shimian Shuangliu, Dqjiangyan, Pengzhou County in Sichuan province, it is one of the endemic fishes in west China. In order to use rare minnow as laboratory animal, scientists of Institute of Hydrobiology belonging to the Chinese Academy of Sciences (CAS)have done a series of investigation from1990.These works refer to its geographical distribution, habitat, morphology, taxonomy, reproduction, ontogenesis, growth,food,semitiviqto ecological factors, karyotype, isozymes, breed and care, anaesthesia,production of inbred strain, and soon. Rare minnow has been inbred to 20th generation at present, and guidelines for the laboratory culture and care of the fish have been made. This implies the time we produce and use rare minnow as standard animal model is near. As a new laboratory animal, rare minnow has the flowing attributes:(1) The ash is small with adult total length 38 to 85mm,and it is easy to care for.(2) Some individuals get mature when they are 3 months old under favorite culture, and can spawn when they are 4 months old.
