Problems solved by technology

Herring is rich in nucleic acid, which can delay aging, and its nutrition is easily absorbed by the human body. It can be used for diet therapy. In addition to 19.5% protein and 5.2% fat, herring also contains calcium, phosphorus, iron, B1, B2 and trace amounts Elemental zinc, adults need 12-16 mg of zinc per day. Herring is rich in trace elements such as selenium and iodine, so it has anti-aging and anti-cancer effects; herring also contains eicosapentaenoic acid (EPA) and 22 Carbasahexaenoic acid (DHA), EPA has the functions of dilating blood vessels and preventing blood coagulation; DHA has an extremely important relationship with brain cells, especially the growth and development of brain nerve conduction and synapses. Due to the high nutritional value of herring, it is therefore There will always be a shortage of supply in the market, so the artificial breeding of herring is currently on the rise, but the herring breeding technology is still relatively traditional, and the survival rate of breeding is extremely low, which seriously criticizes the farmers' desire and enthusiasm for breeding

Embodiment 1

[0021] A method for cultivating herring in ponds, characterized in that: comprising the following steps:

[0022] (1), pond preparation:

[0023] The pond has sufficient water source and no pollution. The water depth is 2.5 meters and the area is 10 mu. After 150 kg melted, the whole pool was splashed, and after filtering and filling every 3 days, the tea seed cake was soaked at 50 kg per mu for 24 hours and then sprinkled. Every 3-5 mu of water surface is equipped with one 3 kW impeller aerator and one bait throwing machine.

[0024] (2), stocking of fish species:

[0025] After filtering and injecting water, stock them around the end of February. Stock 200 to 250 second-year-old herring species with a tail weight of 1 kg per mu, paired with 100 silver carp species with a tail weight of 0.3 kg, 50 bighead carp species with a tail weight of 0.05 kg. 20 snakehead species. Before entering the pond, fish species should be immersed in a mixture of 8 g / m2 copper sulfate and 1 g...

Embodiment 2

[0033] A method for cultivating herring in ponds, characterized in that: comprising the following steps:

[0034] (1), pond preparation:

[0035] The pond has sufficient water source and no pollution. The water depth is 2 meters and the area is 8 mu. After 150 kg melted, the whole pool was splashed, and after 2-3 days of filtration and water injection, 50 kg of tea seed cake per mu was soaked for 24 hours before splashing. Every 4 mu of water surface is equipped with one 3 kW impeller aerator and one bait throwing machine.

[0036] (2), stocking of fish species:

[0037] After filtering and injecting water, stock them around the end of February. Stock 200 to 250 second-year-old herring species with a tail weight of 1 kg per mu, paired with 100 silver carp species with a tail weight of 0.3 kg, 50 bighead carp species with a tail weight of 0.05 kg. 20 snakehead species.

Abstract

The invention discloses a pond cultivation method for black carps, and relates to the technical field of aquaculture. The method comprises the following steps: preparing a pond, freely breeding fish fry, performing feeding by feed, and performing daily management. The method has the beneficial effects that production resources are fully utilized, no professional equipment is needed, cultivation pollution is avoided, the cultivation technology is standard and normative, the feeding is scientific and normative, the polyculture technology is novel, and thus the quality of aquaculture is improvedto a great extent, so that the profits of the black carps are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating herring in ponds. Background technique [0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , which is one of the "four major fish" in freshwater farming in my country. Herring is rich in nutrition. In addition to rich protein and fat, herring also contains rich trace elements such as selenium and iodine, so it has anti-aging and anti-cancer effects. Fish meat is rich in nucleic acid, which is an essential substance for human cells. Nucleic acid Food can delay aging and assist the treatment of diseases. Every 100 grams contains 15.8-20.1 grams of protein, 2.6-5.2 grams ...
