Embodiment 1

[0022] Through 1-to-1 mating between male and female individuals to obtain a family in which all offspring are all orange-red shells, the operation is as follows:

[0023] 1) Parents:

[0024] One mature male and female abalone with bright shell color and orange-red shell color were found in the natural sea area of ​​Dalian, China. The female abalone was named Rw, with a body length of 8.5cm; the male abalone was named Rh, with a body length of 9.8cm.

[0025] 2) Seed abalone to promote ripening: combine Rw and Rh with wild-colored and wild-colored wrinkled abalones to promote ripening, cultivate at 20°C until the effective accumulated temperature reaches 900°C per day, and the density is 25 pieces / m 3 , Daily feeding with fresh kelp, wakame, Ulva macroalgae natural bait. The amount of bait put in is calculated on a daily basis: 30% of the overall body weight of the abalone for ripening, the water is changed once a day, the natural air is filled to supplement the lack of oxyg...

Embodiment 2

[0035] The difference from Example 1 is that a population in which all offspring are orange-red shells is obtained through group mating between male and female individuals. Specifically: Step 2) The water temperature for cultivating abalone in the heat-promoting medium is 16°C, and the density is 80 pieces / m 3 , the effective accumulated temperature is 1400 degrees per day, and the light is 100 Lux; step 3) to induce labor is to dry in the shade for 120 minutes at an indoor temperature of 20°C and a humidity of 90%, then heat up to 23°C, and the ultraviolet irradiation intensity is 1000mwh / L, and discharge after 40 minutes Sperm egg.

[0036] Parents: the species of abalone found in a group of wrinkled pan abalone that has been artificially bred and cultivated indoors. The overall color of the shell is dark orange-red, but there are filamentous orange-red bright rings. The body length of the species was 8.5 in the experiment. ~9.5cm.

[0037] Mating strategy: In this example...

Embodiment 3

[0043] A family in which all offspring are orange-red shell color was obtained through 1-to-1 mating between male and female individuals.

[0044] The source of the parents of this embodiment is the same as that of Example 2; the mating strategy is the same as that of Example 1. Step 2) The water temperature for cultivating abalone to promote ripening is 18°C, and the density is 50 pieces / m 3, the effective accumulated temperature is 1200 degrees per day, and the light is 50Lux; step 3) to induce labor is to dry in the shade for 90 minutes at an indoor temperature of 18°C ​​and a humidity of 70%, then heat up to 23°C, and the ultraviolet irradiation intensity is 700mwh / L, and discharge after 60 minutes Sperm egg. The RR family was bred by mating the shell-color mutant R-3 as the female parent and the shell-color mutant R-4 as the male parent. The RR family currently has 37,800 offspring with a body length of 1.2-1.8cm, all of which are orange-red in color. See Table 3 for th...

Abstract

The breeding method of tangerine shell colour Haliotis discus hannai Ino includes the following steps: using the mutant of it, planting it in sea-water, adding natural food, applying natural air to make its sex gland be developed and matured, adopting the processes of drying in the shade, heating and irradiating sea-water by UV-ray to make stimutation to hasten parturition to obtain female gamete and male gamete, using single cross or group cross mode to make oritificial insemination, and utilizing conventional hatching and post-cultivation method so as to obtain the invented new variety.

Description

technical field [0001] The present invention relates to wrinkle disc abalone, in particular to a wrinkle disc abalone (Haliotis discus hannaiIno) seed production method. Background technique [0002] Abalone wrinkle is one of the most economically important species in the family Haliotidea in my country. It is mainly distributed in the northern part of the Japanese archipelago, the Korean Peninsula, and part of the Liaodong Peninsula and Shandong Peninsula in China. The vast majority of wrinkle plate abalone are dioecious, heterogeneous fertilization, mature individual gonad females are dark blue, males are milky white, and the breeding season is from July to August in the Huangbohai area. my country's relatively concentrated sea areas include Dalian City in Liaoning Province, Yantai, Weihai and Qingdao Sea Areas in Shandong Province. The wrinkled plate abalone is a medium-sized species in the family Abalone, but it is the largest among the species distributed in the sea a...
