Problems solved by technology

[0004] However, P. variegata is still a wild fish and has not been domesticated. If large-scale artificial breeding is to be carried out, it is necessary to domesticate the wild P. variegata first, and then carry out research on artificial reproduction techniques.
However, because Paraloach is not resistant to low oxygen and has not been domesticated, once it leaves the water, it will die soon.

Embodiment 1

[0042] A kind of domestication method of piebald loach, comprising:

[0043] From April to May every year, in the natural distribution water body of the variegated loach, the wild variegated loach is caught with sinking gillnets or trawl nets. Use fishing nets under the water surface to select individuals who are healthy, healthy, and physically strong and meet the age of 3 years or more or have a body length of more than 100mm or a body weight of more than 18g as broodstock.

[0044] Put 10L of water into a double-layer polyethylene plastic bag with a size of 60cm×40cm, add 100mg of MS-222 as an anesthetic, put 1kg of adult fish into the water in the plastic bag, discharge the air in the plastic bag, and inject it into the plastic bag with an oxygen bottle. Fill with pure oxygen, tie the bag tightly and seal it, and transport it in a foam box. When the temperature is above 30°C, place two bottles of frozen water at both ends of the plastic bag in the foam box to cool down. ...

Embodiment 2

[0047] A kind of domestication method of piebald loach, comprising:

[0048] From April to May every year, in the natural distribution water body of the variegated loach, the wild variegated loach is caught with sinking gillnets or trawl nets. Use fishing nets under the water surface to select individuals who are healthy, healthy, and physically strong and meet the age of 3 years or more or have a body length of more than 100mm or a body weight of more than 18g as broodstock.

[0049] Put 10L of water into a double-layer polyethylene plastic bag with a size of 60cm×40cm, add 150mg of MS-222 as an anesthetic, put 1.5kg of adult fish into the water in the plastic bag, discharge the air in the plastic bag, and spray the plastic bag with an oxygen bottle. It is filled with pure oxygen, and the bag is tightly closed after filling, and placed in a foam box for transportation. When the temperature is above 30°C, place two bottles of frozen water at both ends of the plastic bag in th...

Embodiment 3

[0052] A kind of domestication method of piebald loach, comprising:

[0053] From April to May every year, in the natural distribution water body of the variegated loach, the wild variegated loach is caught with sinking gillnets or trawl nets. Use fishing nets under the water surface to select individuals who are healthy, healthy, and physically strong and meet the age of 3 years or more or have a body length of more than 100mm or a body weight of more than 18g as broodstock.

[0054] Put 10L of water into a double-layer polyethylene plastic bag with a size of 60cm×40cm, add 200mg of MS-222 as an anesthetic, put 2kg of adult fish into the water in the plastic bag, discharge the air in the plastic bag, and inject it into the plastic bag with an oxygen bottle. Fill with pure oxygen, tie the bag tightly and seal it, and transport it in a foam box. When the temperature is above 30°C, place two bottles of frozen water at both ends of the plastic bag in the foam box to cool down. ...

Abstract

The invention provides a domestication method and an artificial cultivation method of parabotia fasciata and belongs to the field of wild fish domestication. The domestication method comprises the steps of capturing wild parabotia fasciata as parent fish to transmit to a domestication land. The parent fish is placed into a fish breeding device and domesticated in freshwater, the depth of the freshwater is 60-80 cm, dissolved oxygen content in the freshwater is not less than 6 mg / L, and the stocking intensity in the fish feeding device is not more than 50 per square metre. According to the artificial cultivation method, the parent fish is domesticated by the adoption of the domestication method and artificial reproduction is conducted on the parent fish. The method is simple in operation, good in practice application, high in parent survival rate, and is convenient to achieve mass artificial cultivation on the parabotia fasciata.

Description

technical field [0001] The invention relates to the field of domestication of wild fish, and in particular to a domestication method and an artificial breeding method of paraloach. Background technique [0002] Parabotia fasciata belongs to the subfamily Botiinae. It is a unique fish in my country. It used to be widely distributed in rivers and rivers in China. It is a small benthic fish with certain ornamental value and economic value. economical fish. The variegated loach has the advantages of delicious meat, rich nutrition and high protein content. And compared with loach, the skeleton only has the main vertebra, no intermuscular spines, and it is easy to separate from the muscles, which is more convenient for people to eat. [0003] In recent years, with the aggravation of pollution and eutrophication of water bodies in major river systems, and the construction of large-scale water conservancy projects, the living environment of Paraloach loach has become worse and wors...
