Embodiment 1

[0014] A model ecological breeding method for fugu chrysanthemum for extracting poison, which adopts artificial breeding method for breeding, and is characterized in that it comprises the following steps:

[0015] ① Cultivate wild fish species: take the wild original species of fugu chrysanthemum yellow caught in the coast for breeding, and further breed the larvae;

[0016] ②Regulation of gonad maturation: In the process of larvae culture, the salinity and water temperature are adjusted according to different growth stages, and the water temperature is kept at 19-24°C during the fry cultivation stage (Example 19, 20, 22, 23, 24°C) , the salinity is 6-10‰ (example 6‰, 8‰, 10‰); in the juvenile fish culture stage, the water temperature is kept at 22-30°C (example 22, 24, 26, 28, 30°C), and the salinity is 16~24‰ (example 16‰, 18‰, 20‰, 22‰, 24‰); in the adult fish breeding stage, the water temperature is kept at 18~24°C (example 18, 20, 22, 24°C), and the salinity is 8~12‰ (ex...

Embodiment 2

[0020] When purifying the aquaculture water, it is also treated with a biological bag after filtration and aeration treatment: the porous sand, activated carbon carrier, photosynthetic bacteria and nitrifying bacteria are combined together, and put into the water to purify the water body 20-30 days; then disinfect with 10mg / l chlorine dioxide. All the other are with embodiment 1.

[0021] Of course, the water body can also be treated without biological bag treatment and disinfection.

Abstract

The large-scale artificial culturing process of orange Eastern globefish for extracting tetrodotoxin includes the steps of breeding wild globefish variety, regulating genital gland maturation, controlling food chain, etc. The said process can culture orange Eastern globefish with high tetrodotoxin content, no pollution and other features.

Description

Technical field: [0001] The invention relates to a method for cultivating puffer fish. Background technique: [0002] The artificial breeding of chrysanthemum yellow puffer is more common, but the toxin contained in artificially cultured chrysanthemum yellow fugu is much lower than that of wild species, and ordinary artificial breeding species are not suitable for extracting its toxin. Invention content: [0003] The object of the present invention is to provide a large-scale ecological breeding method for fugu chrysanthemum for extracting poison that can be cultivated into a higher poison content. [0004] Technical solution of the present invention is: [0005] A large-scale ecological breeding method for fugu chrysanthemum for extracting poison, which adopts artificial breeding method for breeding, is characterized in that it comprises the following steps: [0006] ① Cultivate wild fish species: take the wild original species of fugu chrysanthemum yellow caught in the...
