Embodiment 1

[0018] A breeding method for hybrid crucian carp, comprising the steps of:

[0019] 1) The establishment of the fish pond: the selected fish pond is 1.5 mu, 5 days before putting in the fish fry, use 0.05% potassium permanganate acid solution to soak the fish pond for 24 hours, after rinsing, lay 0.02M silt on the fish pond. Keep the dissolved oxygen in the fish pond above 5mg / L.

[0020] 2) Fry feeding: Fry with a tail weight of 0.03 kg is selected, and 1200 fry are put in per mu of fish ponds, and the fry are soaked in 2% salt water for 10 minutes before feeding.

[0021] 3) Feeding feed: when the hybrid crucian carp is 0-200 days old, the daily feeding rate of the hybrid crucian carp feed is 3-5%, and after the hybrid crucian carp is 200 days old, the daily feeding rate of the hybrid crucian carp feed is 3-5%. The ratio is 6%, and the hybrid crucian carp feed is made of the following raw materials in parts by weight: 30 parts of buckwheat, 28 parts of sweet potato, 21 part...

Embodiment 2

[0028] A breeding method for hybrid crucian carp, comprising the steps of:

[0029] 1) The establishment of the fish pond: the selected fish pond is 3 mu, 7 days before putting in the fish fry, use 0.05% potassium permanganate acid solution to soak the fish pond for 0h, after rinsing, lay 0.1M silt on the fish pond.

[0030] The fish pond is equipped with an aerator, which can automatically operate according to the dissolved oxygen in the fish pond to keep the dissolved oxygen in the fish pond above 5mg / L.

[0031] 2) Fry stocking: choose 0.04kg fish stock, put 1400 fish stock per mu into the pond, and soak in 2% salt water for 20 minutes before stocking.

[0032]3) When the hybrid crucian carp is 0-200 days old, the daily feeding rate of the hybrid crucian carp feed is 5%, and after the hybrid crucian carp is 200 days old, the daily feeding rate of the hybrid crucian carp feed is 8%.

Abstract

The invention relates to the technical field of breeding, in particular to a breeding method of hybridized crucian. The method comprises the following steps of 1, adopting a potassium permanganate solution for disinfection before fry are put into a fishpond; 2, sterilizing the fry before the fry are put into the fishpond; 3, feeding the crucian with feed, wherein the feed for the hybridized crucian is prepared from, by weight, 30-60 parts of buckwheat, 28-32 parts of sweet potatoes, 21-25 parts of fish meal, 14-18 parts of sesame seed meal, 12-15 parts of dried small shrimps, 23-28 parts of lotus roots, 8-12 parts of Chinese yam, 18-20 parts of leaves of asparagus lettuce, 10-13 parts of tomatoes and 6-8 parts of mushrooms; 4, conducting breeding management, wherein water is periodically changed, and EM is periodically sprayed. By means of the breeding method of the hybridized crucian, the mouthfeel of the hybridized crucian can be effectively improved, cholesterol in fish flesh is reduced, and the diseases of the hybridized crucian can be reduced.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for cultivating hybrid crucian carp. Background technique [0002] Crucian carp is an omnivorous fish that mainly feeds on plants. The meat is tender, sweet and has a high nutritional value. Every 100 grams of meat contains 13 grams of protein, 11 grams of fat, and contains a lot of calcium, phosphorus, iron, etc. Minerals: Crucian carp has extremely high medicinal value. Its nature and flavor are sweet, flat, and warm. It enters the stomach and kidneys. Crucian carp is widely distributed, except for the western plateau, it is widely distributed all over the country. Crucian carp is very adaptable, whether it is deep water or shallow water, running water or still water, it can survive in water from 0°C to 32°C, even at a pH of around 9 It can still grow and reproduce in lake water with a salinity as high as 4.5%. Hybrid crucian carp is the offspring obtained by cro...
