Abstract

The invention discloses a crucian carp breeding method. According to the method, a reservoir is selected, net cages are placed in the reservoir, before 15 to 17 days from fingerlings are put into a pond, quicklime is used for clearing the pond; fish fries are put into the net cages, the temperature of the reservoir is controlled to be 10 to 12 DEG C, bait is fed for 4 to 6 times in each day, the particle size of the bait is 2 to 3mm, and the feeding is 30 to 40 minutes in each time; the dissolved oxygen of the pond water is maintained to be more than 3mg/L every day, and fresh water is added and injected for regulating the water level in each half month; pesticides are regularly splashed, and the quicklime or bleaching powder is splashed once every half month; from June to September in each year, coarse salt is fed for many times and is fed once every half month, meanwhile, the fishing is carried out for many times, and the crucian carps can be caught when growing to 230g to 500g. Before fingerlings enter the pond, the sterilization is carried out, an aerator is turned on for providing sufficient oxygen for the growth of crucian carps, the water is replaced frequently, the pond water is cleaned frequently, the influence on the health of the fish fries caused by bacterium propagation is avoided, the quick lime or bleaching powder is poured and spread every half month, the coarse salt is fed for many times and are respectively used for sterilizing the pond water, and the morbidity of the fish is reduced.

Description

The cultural method of a kind of crucian

Technical field

The present invention relates to the cultural method of a kind of crucian.

Background technology

Crucian is that mainly to take plant be the omnivorefish of food, and happiness is trooped and go, selects to eat and occupy fine and tender taste, meat flavour is sweet, and nutritive value is very high, in crucian cultivation process, the most important thing is to prevent fish disease evil, guarantee that Chi Shui is clean, enter especially hot weather, guarantee the oxygen content of fish.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

For addressing the above problem, the invention provides a kind of cultural method that reduces the crucian of fish disease evil.

The technical solution used in the present invention:

A cultural method for crucian, comprises the following steps:

A, selection reservoir are placed net cage in reservoir, and fingerling enters 7-15 days before pond, with quicklime, cleans up the pond;

B, in net cage, put into fry, reservoir temperature is controlled at 10-12 ℃, day bait throwing in material 4-6 time, and bait particle diameter 2-3 ㎜, 30-40 minute throws something and feeds at every turn;

Open aerator 1-2 hour at c, noon every day, more than keeping pond water dissolved oxygen 3mg/L, every first quarter moon new water of once annotating regulates water level, and in 7-8 month, the new water of annotating once in a week adds water level to 20-25cm at every turn;

D, the regular medicine of splashing, every two weeks splash quicklime or bleaching powder, the every mu of 10-15 kilogram that splashes;

E, annual 6, between September, repeatedly throws in crude salt, every two weeks, throws once, repeatedly fishes for simultaneously, and crucian is supported between 230-500 gram and can fish for.

Described bait comprises colza cake, corn flour, wheat bran and soybean curb residue.

The quality proportioning of described colza cake, corn flour, wheat bran and soybean curb residue is 10:3:2:1-2.

Advantage of the present invention is: fingerling enters before pond;, through sterilization, open aerator, for crucian growth provides enough oxygen; often change water; clean Chi Shui, avoids bacteria breed, affects the health of fry; every two weeks splash quicklime or bleaching powder; repeatedly throw in crude salt, be pond water sterilization, reduce the incidence of disease of fish.

Embodiment

Following embodiment is only for the present invention is described, but can not limit protection scope of the present invention.

Embodiment 1

A cultural method for crucian, comprises the following steps:

A, selection reservoir are placed net cage in reservoir, and fingerling enters pond first 7 days, with quicklime, cleans up the pond;

B, in net cage, put into fry, reservoir temperature is controlled at 10 ℃, day bait throwing in material 4 times, and bait particle diameter 2 ㎜ throw something and feed 30 minutes at every turn;

C, noon every day are opened aerator 1 hour, and more than keeping pond water dissolved oxygen 3mg/L, every first quarter moon new water of once annotating regulates water level, and in July, the new water of annotating once in a week adds water level to 20cm at every turn;

D, the regular medicine of splashing, every two weeks splash quicklime or bleaching powder, splash 10 kilograms for every mu;

E, annual 6, between September, repeatedly throws in crude salt, every two weeks, throws once, repeatedly fishes for simultaneously, and crucian is supported between 230 grams and can fish for.

Bait comprises colza cake, corn flour, wheat bran and soybean curb residue, and the quality proportioning of colza cake, corn flour, wheat bran and soybean curb residue is 10:3:2:1.

Embodiment 2

A cultural method for crucian, comprises the following steps:

A, selection reservoir are placed net cage in reservoir, and fingerling enters pond first 10 days, with quicklime, cleans up the pond;

B, in net cage, put into fry, reservoir temperature is controlled at 11 ℃, day bait throwing in material 5 times, and bait particle diameter 2.5 ㎜ throw something and feed 35 minutes at every turn;

C, noon every day are opened aerator 2 hours, and more than keeping pond water dissolved oxygen 3mg/L, every first quarter moon new water of once annotating regulates water level, and in July, the new water of annotating once in a week adds water level to 22cm at every turn;

D, the regular medicine of splashing, every two weeks splash quicklime or bleaching powder, splash 12 kilograms for every mu;

E, annual 6, between September, repeatedly throws in crude salt, every two weeks, throws once, repeatedly fishes for simultaneously, and crucian is supported between 350 grams and can fish for.

Bait comprises colza cake, corn flour, wheat bran and soybean curb residue, and the quality proportioning of colza cake, corn flour, wheat bran and soybean curb residue is 10:3:2:2.

Embodiment 3

A cultural method for crucian, comprises the following steps:

A, selection reservoir are placed net cage in reservoir, and fingerling enters pond first 15 days, with quicklime, cleans up the pond;
