The curled-lip mandarin fish and spotted mandarin fish hybridizing propagation process includes the following steps: 1. reinforced culturing curled-lip mandarin fish as female parent fish and spotted mandarin fish as male parent fish; 2. injecting exogenous hormone to promote mature and induce spawning, flowing water stimulating to promote spawning, artificial dry insemination and managing duringhatching, so as to reach spawning rate over 80 %, fertility rate up to 83.5 % and hatching rate up to 89 %; and 3. staged culturing of the hybrid mandarin fish and feeding habit conversion from live fish to non-live feed, so as to reach survival rate of hybrid mandarin fish fry up to 60 %. The hybrid mandarin fish has good taste, high disease resistance, high growth speed and capacity of ingesting non-live fish feed.
