Studies on the Technology of Artificial
Domestication and Reproduction of
Abstract: Since 2003, the protospecies of Barbodes fuxianensis, collected from their patria Fuxian Lake, have been domesticated and bred at Yuxi Paleoecological Schizothorax Taliensis Scientific Research and Conservation Center. In 2009, for the first time, Barbodes fuxianensis with well developed gonad were used to research the technology of artificial domestication and reproduction of Barbodes fuxianensis. Two methods have been adopted in the research-simulating natural ecological environment for Barbodes fuxianensis to reproduce: artificially injecting hormone to induce spawning and using dry method of artificial fertilization. The former method has not succeeded so far, while fertilized eggs (whose fertilization rate was over 70%) were obtained in 2009 by injecting luteinizing hormone to release hormone analogue and using the dry method of artificial fertilization. Hydrostatic incubation in outdoor incubator and hydrostatic incubation in indoor incubator have made the hatchability of fertilized eggs over 85%, indicating that the artificial propagation of Barbodes fuxianensis has succeeded. During the past five years, all the artificial propagation experiments which used the same technology have achieved success. In 2013, the first filial generation of Barbodes fuxianensis, artificially bred in 2009, has matured sexually and reproduced the second generation successfully.
