The invention relates to a Haliotis discus hannai Ino, especially to a method for cultivating novel species of it with tangerine color shell. The method can be realized by way of single cross or group cross. It includes steps of selecting mature abalones of tangerine color shell mutant as breeding abalones, putting them in the seawater, feeding them with natural bait, provide them with air until their sex gland develop to mature; hastening their parturition by drying in the shade, heating and radiating seawater with ultraviolet; obtaining their female and male gametes to artificially fertilize them by way of single cross or group cross, generally spawn incubating and upper cultivating them. Advantages of the present method consist of breeding a novel species of Haliotis discus hannai Ino with vivid characteristic and introducing no foreign gene. The method can be operated with a simple way and its production conditions are better than that of general Haliotis discus hannai Ino so as to apply the method to the industrial production. |
