摘要 [Objective]To improve the artificial propagation technique of Misgurnus anguillicaudatus,and to provide technical support for the industrialization development of M.anguillicaudatus in future.[Methods] The hatching rates,survival rates,deformity rates and parent morality rates of M.anguillicaudatus were compared by ecological hatching method and traditional hatching method.[Results]The hatching rate by ecological hatching method was 32.60% higher than that by traditional hatching method,showing extremely significant differences.The survival rate of M.anguillicaudatus fingerlings by ecological hatching method was2.32% higher than that by traditional hatching method.And the deformity rates of M.anguillicaudatus fingerlings by traditional hatching method and ecological hatching method were 26.50% and 24.14%,respectively,indicating no significant differences.The morality rates of female parents of M.anguillicaudatus were89.72% and 5.91% by traditional hatching method and ecological hatching method,respectively.[Conclusions]Ecological hatching method effectively improved the hatching rate and fingerling survival rate of M.anguillicaudatus,and reduced the morality rate of female parents,which was helpful to save the production cost,met the requirements for large-scale production of M.anguillicaudatus,and had good application prospect.
