Problems solved by technology

It has been reported in many places in my country. It is a kind of ancient primitive invertebrates. Due to the current scarcity, the research has always remained in the classification, and there has been no report on artificial reproduction.
[0003] Since the peach blossom jellyfish was named in the UK in 1880, its life history has been unclear, and there have been no reports of successful artificial cultivation.

Embodiment 1

[0015] (1) Catch provenance: in natural water bodies with the distribution of jellyfish, catch jellyfish with a umbrella diameter greater than 0.5cm and strong mobility for use;

[0016] (2) Matching provenance: select the individual umbrella diameter as 0.5-4cm, strong mobility, complete tentacles, and the jellyfish jellyfish with visible gonads as the provenance, and according to the ratio of male to female ratio of 1:1-30, the present embodiment Select provenance at a ratio of 1:10, move to PH6.4, water body dissolved oxygen 10mg / L, polyculture under the condition of light 1000LX, the best breeding density is 5-30 / L, too much will affect the water quality. If the growth rate of the parent body is too small, it will affect the number of cultivation and waste resources. In this embodiment, it is 10 / L;

[0017] (3) Feeding: Feeding small planktonic crustaceans, such as spiny daphnia, hyaline hyaline, senile daphnia, etc., or feeding copepods such as Daphnia mesida, Daphnia hye...

Embodiment 2

[0021] (1) Catch provenance: in natural water bodies with the distribution of jellyfish, catch jellyfish with a umbrella diameter greater than 0.5cm and strong mobility for use;

[0022] (2) Matching provenance: select the individual umbrella diameter as 0.5-4cm, strong mobility, complete tentacles, and the jellyfish jellyfish with visible gonads as the provenance, and according to the ratio of male to female ratio of 1:1-30, the present embodiment Select provenance at a ratio of 1:30, move to PH7.4, water body dissolved oxygen 21.7mg / L, polyculture under the condition of light 800LX, the best breeding density is 5-30 / L, too much will affect The jellyfish body growth rate, too little then affects the cultivation quantity, wastes resources, and the present embodiment is 30 / L;

[0023] (3) Feeding: Feeding small planktonic crustaceans, such as Cladocera spiny daphnia, hyaline hyaline, senile daphnia, etc., or feeding copepods such as Daphnia mesalis and Daphnia lucidus , close ...

Embodiment 3

[0027] (1) Catch provenance: in natural water bodies with the distribution of jellyfish, catch jellyfish with a umbrella diameter greater than 0.5cm and strong mobility for use;

[0028] (2) Matching provenance: select the individual umbrella diameter as 0.5-4cm, strong mobility, complete tentacles, and the jellyfish jellyfish with visible gonads as the provenance, and according to the ratio of male to female ratio of 1:1-30, the present embodiment Select the provenance at a ratio of 1:1, move to PH8.6, water body dissolved oxygen 3mg / L water, polyculture under the condition of light 1200LX, and the breeding density is 1 / L;

[0029] (3) Feeding: Chlorella is fed, and the specific times and quantity depend on the needs. In this embodiment, 1 gram per liter of water per week is selected for use. Feed until the gonads of the jellyfish mature;

[0030] (4) When the gonads of the jellyfish are mature, eggs and sperm can be discharged respectively, and when the eggs and sperm are f...

Abstract

An artificial reproduction technique for craspedacusta includes such steps as capturing the parents with high activity, complete body and visual sexual gland, choosing and pairing, culturing in the water with pH=6.4-8.6 and dissolved oxygen (3.0-21.7 mg / L) under illuminance of 800-1200 Lx, feeding small crustacena plankton and seaweed, culturing hydroids, culturing larvae, and culturing adults.

Description

technical field [0001] The invention relates to a coelenterate breeding technology, in particular to an artificial breeding method of jellyfish. Background technique [0002] Peach jellyfish belongs to the phylum Cnidaria, class Hydrozoa, order Freshwater Jellyfish, family Jellyfish, and genus Peach Blossom. It has been reported in many places in my country. It is a kind of ancient primitive invertebrates. Due to the current scarcity, the research has always remained on the classification, and there has been no report on artificial reproduction. [0003] Since the peach blossom jellyfish was named in the UK in 1880, its life history has been unclear, and there have been no reports of successful artificial cultivation. Carrying out artificial breeding and cultivation not only enables this precious and rare species to be better continued, but also meets people's ornamental needs. Contents of the invention [0004] The object of the present invention is to provide a method ...
