Embodiment

[0024] A method for breeding California sea cucumber seedlings, the steps are:

[0025] 1. Pro ginseng: Promotes maturity and pro ginseng, so that half of the individuals' gonadal index is greater than 15%, normal posture, no injury, no viscera, no abnormality;

[0026] 2. Eggs and hatching:

[0027] (1) Through artificial egg collection and fertilization method, combined temperature increase, spirulina addition induction and dry water stimulation method, dry water, running water and other comprehensive methods, stimulate the parent ginseng to lay eggs and complete the egg collection;

[0028] (2) Washing eggs: remove the ginseng in time after fertilization, and wash the eggs several times with clean seawater through drainage and adding water (for drainage, use a 260-mesh net box to siphon outward); made with 300-mesh sieve After the eggs are concentrated in the net cage, they are washed with clean sea water several times;

[0029] (3) Incubation: environmental conditions: salinity at ...

Abstract

The invention discloses a method for breeding a California sea cucumber fry. The method comprises the steps of 1, a parent sea cucumber, wherein the parent sea cucumber is ripened, the gonad indexes of half of the individuals are higher than 15%, and half of the individuals are normal in posture, no damage, no eversion of viscera and no abnormalities; 2, spawn and incubation; 3, juvenile sea cucumber selecting and breeding; 4, seedling collection; 5, young sea cucumber breeding; 6, juvenile sea cucumber breeding and developing; according to the method, through a series of studies such as the reproductive adjustment, ripening and breeding for the parent sea cucumber, spawn collection and incubation, juvenile sea cucumber selecting and breeding, seedling collection and young and juvenile sea cucumber developing, specific implementation steps of breeding California sea cucumber fry are formulated, and the method is beneficial for the development of sea cucumber.

Description

Technical field [0001] The invention relates to the technical field of sea cucumber seed breeding, in particular to a method for California sea cucumber seed breeding. Background technique [0002] California sea cucumber is native to North America and is an important economic species in the intertidal zone from California to Alaska. Because of its tender meat, rich nutrition, large individual, spiny body wall, thick meat, and good taste, it has been favored by consumers at home and abroad for many years. Favor. [0003] At present, there has been an upsurge in breeding California sea cucumbers in different regions, but there is no specific technical plan for the breeding technology of California sea cucumbers. Summary of the invention [0004] The purpose of the present invention is to provide a method for breeding California sea cucumber seedlings against the defects and deficiencies of the prior art. [0005] In order to achieve the above-mentioned purpose, the technical solution...
