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...
