Embodiment 1

[0020] ①Artificial reproduction: Take adult oriental porcupines cultured under freshwater conditions as parents, and bury Japanese W / O / W emulsion hormone packs in their bodies to breed seedlings;

[0021] ②Fryling cultivation: use purebred freshwater Brachionus rotifer as fry opening feed to cultivate;

[0022] ③ Cultivation of seedlings and adult fish: Feed the compound feed without tetrodotoxin at the seedling and adult stage, and feed the sex late maturation factor; when feeding the compound feed without tetrodotoxin, feed the seedlings 4 to 6 times a day (can be 4, 5, 6 times), the feeding rate is 5-10% (it can be 5, 7, 10%), the adult fish is fed 2-3 times a day, the feeding rate is 1-3% (it can be 1 , 2, 3%). When feeding sex slow maturing element, feed once every 5-15 days (can be 5, 10, 15 days), and the feeding rate is 0.01-1% (can be 0.01, 0.1, 0.3, 0.6, 0.8, 1.0%) .

[0023] Among them, the compound feed without tetrodotoxin is a compound containing fish meal, st...

Embodiment 2

[0044] Tetrodotoxin-free compound feed consists of the following components by weight:

[0045] Fishmeal 68%

[0046] Starch 20%

[0047] Spirulina 3%

[0048] L-Methionine 0.1%

[0049] Cornmeal 5%

[0050] Soy 0.9%

[0051] Vitamin B 1 1%

[0052] Vitamin B 2 1%

[0053] Vitamin B 6 1%. All the other are the same as in Example 1.

Embodiment 3

[0055] Tetrodotoxin-free compound feed consists of the following components by weight:

[0056] Fishmeal 72%

[0057] Starch 11%

[0058] Spirulina 2.2%

[0059] L-Lysine 0.3%

[0060] Soy 10%

[0061] Vitamin 0.5%

[0062] Skullcap 2%

[0063] Banlangen 2%. All the other are the same as in Example 1.

Abstract

The domesticating and culturing process of dark-grained Eastern globefish with controlled tetrodotoxin includes the steps of artificial propagation, fry culture, globefish culture, etc. The present invention makes it possible to control the tetrodotoxin content under fresh water culture condition simply without pollution.

Description

Technical field: [0001] The invention relates to a method for cultivating puffer fish. Background technique: [0002] Due to its certain toxicity, the obscura is subject to certain restrictions in terms of consumption and other aspects. Invention content: [0003] The object of the present invention is to provide a method for controlling the toxin content of the domesticated oriental porpoise under the condition of freshwater culture, which can effectively control the toxin content. [0004] Technical solution of the present invention is: [0005] A method for controlling the poison of the Jahwa oriental porpoise, which is characterized in that it comprises the following steps: [0006] ①Artificial reproduction: Take adult oriental porcupines cultured under freshwater conditions as parents, and bury hormone packs in their bodies to breed seedlings; [0007] ②Fryling cultivation: use purebred freshwater Brachionus rotifer as fry opening feed to cultivate; [0008] ③ Cul...
