Embodiment 1

[0036] The invention provides a method for artificial seedling cultivation of black-legged abalone, which method comprises:

[0037] S101: Cultivate the imported or purchased black-footed abalone under the condition of seawater temperature of 14° C. until the gonad maturity of the black-footed abalone reaches 20-30%.

[0038] S102: By adjusting the photoperiod and light quality, the gonad maturity of black-footed abalone was promoted from 20% to 65%.

[0039] S103: After the gonad maturity of the black-legged abalone reaches 65%, the water temperature is increased to 17°C, and the photoperiod and light quality are adjusted at the same time to promote the development of the gonad maturity of the black-footed abalone from 65% to 95%.

[0040] S104: Dry the black-footed abalone with a gonad maturity of 95% in the shade for 1 hour, and place the dried black-footed abalone individually into an oxytocin solution at a water temperature of 17° C., so that the black-footed abalone can ...

Embodiment 2

[0046] The invention provides a method for artificial seedling cultivation of black-legged abalone, which method comprises:

[0047] S201: Cultivate the imported or purchased black-legged abalone under the condition of seawater temperature of 16° C. until the gonad maturity of the black-footed abalone reaches 30%.

[0048] S202: By adjusting the photoperiod and light quality, the gonad maturity of the black-footed abalone was promoted from 30% to 75%. The black-footed abalone whose gonad maturity is promoted to 75% is cultivated at a temperature of 15°C to provide seed abalone for the annual seedling cultivation of the black-footed abalone.

[0049] S203: After the gonad maturity of the black-legged abalone reached 75%, the water temperature was increased to 17°C, and the photoperiod and light quality were adjusted at the same time to promote the gonad maturity of the black-footed abalone to develop from 75% to 98%.

[0050] S204: Prepare H with a concentration of 60g / L respe...

Embodiment 3

[0056] The invention provides a method for artificial seedling cultivation of black-legged abalone, which method comprises:

[0057] S301: Cultivate the introduced or purchased black-footed abalone under the condition of seawater temperature of 15° C. until the gonad maturity of the black-footed abalone reaches 25%.

[0058] S302: By adjusting the photoperiod and light quality, the gonad maturity of the black-footed abalone is promoted from 25% to 70%. The black-footed abalone whose gonad maturity is accelerated to 70% is cultured at a temperature of 15°C to provide seed abalone for the annual seedling cultivation of the black-footed abalone.

[0059] S303: After the gonad maturity of the black-footed abalone reached 70%, the water temperature was increased to 17°C, and the photoperiod and light quality were adjusted at the same time to promote the gonad maturity of the black-footed abalone to develop from 70% to 98%.

Abstract

The invention provides an artificial breeding method of haliotis iris. The artificial breeding method comprises: promoting maturity of the haliotis iris with gonadal maturity of 20-30% to be 65-75% by adjusting an illumination period and light quality; and adjusting the illumination period again to promote the maturity of gonads so as to enable sperms or ova of the haliotis iris to be mature. The haliotis iris with mature gonads releases sperms or ova under stimulation of drying in the shade, H2O and NaOH. A parent abalone releases sperms or ova in a single spawning induction tank, the sperms can be added according to the number of the ova to increase the utilization rate of the ova and improve the fertility rate. Fertilized ova are put into a hatching pond for hatching after washing. Floating larvae after hatching are transferred into a nursery pond with an attachment substrate through a siphonage before metamorphosis so as to attach and metamorphose into juvenile abalones. The method provided by the invention is simple and convenient to operate, the haliotis iris is mature in gonad development, and relatively high in sperm or ovum releasing rate, and the fertility rate can reach 85%. In addition, the haliotis iris of which the gonad maturity is promoted to be 65-75% is cultivated in an environment at a temperature of 15 DEG C, thereby facilitating breeding all year round.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an artificial breeding method for black-footed abalone. Background technique [0002] Abalone is a valuable marine edible shellfish, known as "soft gold", and known as the first of the eight seafood treasures. The fresh edible part of abalone contains 24% protein; the dry product contains 40% protein, 33.7% glycogen and other nutrients. Therefore, abalone has high nutritional value. In addition, as a precious food material, abalone also has the effects of improving eyesight and tonifying deficiency, clearing heat and nourishing yin, nourishing blood and benefiting stomach, etc. Therefore, abalone has high medicinal value. Due to the nutritional value and medicinal value of abalone, abalone has potential market value. [0003] my country is the country with the largest abalone farming scale and output in the world, and its output accounts for 79% of the world's abalone outpu...
