The Fuxian golden line ( Sinocyclocheilus tingi ) is a famous fishendemic to Fuxian Lake. From March to April 2009, four breedingexperiments were undertaken. 40 females and 20 males were injected withhormones. 19 females and 15 males bred successfully, accounting for47.5% of females and 75.0% of males. A total of 25 547 eggs wereobtained and subjected to dry-fertilization, with 16 810 eggs beingfertilized with a 65.8% success rate. 6 040 larvae were obtained with a23.6% hatching rate. 3 056 larvae survived 20 days of cultivation witha 50.6% survival rate. Reproductive dysfunctions are major constrainingfactors to low Induced spawning of S. tingi in a captive environment.Artificial conditions that did not reflect the necessary naturalenvironment of the fish may have also been a factor. This paper alsoaddresses the issue of massive larvae mortality. Determining theconstraints of artificial propagation is critical to the transfer ofthis species into cultivation fish. The presented success inpropagation of S. tingi will contribute to understanding its biologyand protection from extinction.
