Problems solved by technology

[0003] Hybrid breeding is one of the important ways of artificial breeding of marine organisms. Although hybrid breeding has been widely used in recent years, due to the difficulty of interspecific hybridization, the advantages are not obvious, and the advantage of intraspecific hybrid offspring is difficult to maintain. The successful examples are not a lot of

Embodiment 1

[0013] 1) Selection of species of abalone The wild mature males ( ) 6 ear abalones with a body length of 2.7-9.7 cm; 12 wild female (♀) ear abalones from the coast of Hainan Island with a body length of 3-8.4 cm.

[0014] 2) Breeding abalone to accelerate ripening and induce labor Put the male and female parents together to accelerate ripening, place them in seawater at 28°C, feed them with natural bait such as kelp, Gracilaria, Eucheuma, etc. every day, inflate them, change the water once, until the gonads mature. It is firstly stimulated by drying in the shade at room temperature for 1 hour, then adding seawater irradiated by ultraviolet lamps to induce stimulation, and at the same time combining repeated heating and cooling stimulation to make it spawn or ejaculate.

[0015] 3) Insemination The male and female gametes obtained respectively are artificially inseminated.

[0016] 4) Incubation and post-cultivation process

[0017] Follow conventional incubation and post-cu...

[0020] 1) The parents were wild mature males from the sea area of ​​Dongsha Islands ( ) five ear abalones, body length 2.5-9.2cm; select 10 wild female (♀) ear abalones along the coast of Hainan Island, body length 2.4-8.4cm.

[0021] 2) Breeding abalone to accelerate ripening and induce labor Put the male and female parents together to accelerate ripening, place them in seawater at 28°C, feed them with natural bait such as kelp, Gracilaria, Eucheuma, etc. every day, inflate them, change the water once, until the gonads mature. It is firstly stimulated by drying in the shade at room temperature for 1 hour, then adding seawater irradiated by ultraviolet lamps to induce stimulation, and at the same time combining repeated heating and cooling stimulation to make it spawn or ejaculate.

Embodiment 3

[0026] 1) Parents were selected from wild mature males in the sea area of ​​Thailand ( ) 4 ear abalones with a body length of 2.8-9.0 cm; 10 wild female (♀) ear abalones from the coast of Hainan Island with a body length of 2.5-8.3 cm.

[0027] 2) Breeding abalone to accelerate ripening and induce labor Put the male and female parents together to accelerate ripening, place them in seawater at 28°C, feed them with natural bait such as kelp, Gracilaria, Eucheuma, etc. every day, inflate them, change the water once, until the gonads mature. It is firstly stimulated by drying in the shade at room temperature for 1 hour, then adding seawater irradiated by ultraviolet lamps to induce stimulation, and at the same time combining repeated heating and cooling stimulation to make it spawn or ejaculate.

[0028] 3) Insemination The male and female gametes obtained respectively are artificially inseminated.

Abstract

The intraspecific crossing process of Haliotis asinina of different geographic colonies includes the procedures of seed selection, promoting mature and induced spawning, insemination, hatching and cultivating. The process is simple and easy to operate, and can obtain Haliotis asinine fry with the excellent characters of its parents. The present invention is suitable for industrial production.

Description

technical field [0001] The invention relates to an intraspecific hybridization method of Haliotis asinina Linnaeus, in particular to an intraspecific hybridization method of Haliotis asinina Linnaeus in different geographical groups. Background technique [0002] Abalone is a precious marine mollusk with well-developed legs, tender meat, delicious taste and rich nutrition. It is known as the crown of seafood and has high economic value. There are about 90 species of Abalone, which are distributed in all oceans of the world. The shell of the ear abalone (Haliotis asinina Linnaeus) is small and flat, in the shape of an ear, the shell is long, the shell width is less than 1 / 2 of the shell length, and the shell height is about 1 / 3 of the shell width. Ear abalone is a species of warm water, mainly distributed in the Indo-Pacific region. The spawning season of ear abalone is mostly in summer and autumn. Ear abalone shell is thin and fleshy, and the foot muscles are particularly...
