Problems solved by technology

Large-scale breeding of moon jellyfish requires a large number of polyp breeding. The traditional method of cultivating polyp adopts mixed feeding of female and male jellyfish to change the temperature to stimulate fertilization, but the reproduction speed is slow, the reproduction amount is small, and it is unstable.

Embodiment 1

[0017] The method for cultivating the jellyfish polyps in the present embodiment, its specific steps are:

[0018] (1) Select moon jellyfish with an equal number of females and males. Sexually mature jellyfish with strong mobility, no external trauma, and beautiful color are required to meet the growth period of not less than 3 months.

[0019] (2) Cut about 1 cm squares from the outside of the gonads of female and male jellyfish in water, put them in the incubator, and cut the gonads into small pieces of about 1 mm.

[0020] (3) Stir and mix with a 300r / min mixer to fully mix the sperm and eggs for 10 minutes.

[0021] (4) Maintain the water temperature at 25°C, use a chiller to cool down in high temperature seasons, and use heating rods to maintain a constant temperature in the incubator in winter, and the floating larvae will be obtained after 6 hours.

[0022] (5) Continue to maintain the water circulation in the body, the circulating water flow rate is 8cm / s, and after 1...

Embodiment 2

[0026] The method for cultivating the jellyfish polyps in the present embodiment, its specific steps are:

[0027] (1) Select moon jellyfish with an equal number of females and males. Sexually mature jellyfish with strong mobility, no external trauma, and beautiful color are required to meet the growth period of not less than 3 months.

[0028] (2) Cut about 1 cm squares from the outside of the gonads of female and male jellyfish in water, put them in the incubator, and cut the gonads into small pieces of about 1 mm.

[0029] (3) Stir and mix with a 300r / min mixer to fully mix the sperm and eggs for 10 minutes.

[0030] (4) Maintain the water temperature at 25°C, use a chiller to cool down in high-temperature seasons, and use heating rods in winter to keep the temperature in the incubator constant for about 7 hours, and then get the floating larvae.

[0031] (5) Continue to maintain the circulation in the water body, the circulating water flow rate is 9cm / s, and after 12 hour...

Embodiment 3

[0035] The method for cultivating the jellyfish polyps in the present embodiment, its specific steps are:

[0036] (1) Select moon jellyfish with an equal number of females and males. Sexually mature jellyfish with strong mobility, no external trauma, and beautiful color are required to meet the growth period of not less than 3 months.

[0037] (2) Cut about 1 cm squares from the outside of the gonads of female and male jellyfish in water, put them in the incubator, and cut the gonads into small pieces of about 1 mm.

[0038] (3) Stir and mix with a 300r / min mixer to fully mix the sperm and eggs for 10 minutes.

[0039] (4) Maintain the water temperature at 25°C, use a chiller to cool down in high-temperature seasons, and use heating rods in winter to keep the temperature in the incubator constant for about 8 hours, and the larvae will be obtained.

[0040] (5) Continue to maintain the circulation in the water body, the circulating water flow rate is 10cm / s, and after 15 hour...

Abstract

The invention relates to a culturing method of aurelia scyphistoma. The culturing method specially comprises the following steps of (1) selecting male and female aurelia with the same amount; (2) shearing about 1cm square blocks from the outer side of gonad inferior vena of the corresponding male and female Aurelia, putting into a culture box, and shearing the gonad into about 1mm small blocks; (3) stirring and mixing by a stirring machine with rotation speed of 300r / min, and fully mixing sperm and ovum; (4) maintaining the water temperature at 25 DEG C; (5) continuously maintaining the inner circulation of a water body, controlling the flow rate of the circulating water as 8-10cm / s, and putting the planula larvae into a disinfected plastic corrugated plate after 10-15h; (6) feeding artemia salina twice each day, and changing 50% of water each day. The culturing method has the advantages that the aurelia scyphistoma can be stably cultured in different seasons, so a large amount of aurelia can be propagated; the maturing culture of large amount of aurelia can be completed within 11 days, so the propagation cycle of the aurelia under the natural environment is greatly shortened, and the production amount of the aurelia is improved.

Description

technical field [0001] The invention relates to a method for cultivating a polyp of a jellyfish, belonging to the technical field of artificial propagation of a jellyfish. Background technique [0002] Moon jellyfish is a highly ornamental jellyfish, which contains a lot of collagen, which can be used to extract the collagen needed by the human body. Large-scale breeding of moon jellyfish requires a large number of polyp breeding. The traditional method of cultivating polyp adopts mixed breeding of female and male jellyfish and changes in temperature to stimulate fertilization, but the reproduction speed is slow, the reproduction amount is small, and it is unstable. Contents of the invention [0003] The object of the present invention is to provide a method for efficiently, rapidly and stably propagating the polyp of jellyfish jellyfish. [0004] In order to achieve the above object, the technical solution of the present invention is as follows. [0005] A kind of sea m...
