More than 20 acres of water surface, how many grass carp can be placed!

The water depth is 4-5 meters five, and it is best to grow fish.

If the water quality is good, the 20 acres of reservoir can be stocked with 8,000 grass carp and 20,000 crucian carp at the same time.

10,000 tails;

If the water quality is not good, the population should be reduced, and 6,000 grass carp, 15,000 crucian carp and 7,000 silver carp should be stocked at the same time.

There can not be too many ducks in the free-range, 200 are enough, too much water is too fat, and it is easy to lack oxygen.

20 acres can breed about 30,000 osmanthus fish.

If the breeding is an adult, relatively large size of the osmanthus fish, the number of fish that can be cultivated per mu is about 1,500, so 20 acres can raise about 30,000. If the size of the farmed osmanthus fish is small, the number of cultured fish can be increased appropriately. However, if the water is shallow, the number of cinnamon should be reduced.

If polyculture with other fish is to be carried out, the number of cinnamon fish should also be appropriately reduced.

Generally, 1,200 fish can be raised in one acre of fish pond, and about 24,000 fish can be raised in a fish pond with 20 acres of water surface.

About 3,000 catties of carp per mu of pond are good, with about 300 catties of other fish, too much stocking is prone to disease, and the cost of breeding has increased dramatically. Generally speaking, grass carp are polycultured! Now let's look at the four big fish in Henan.

The highest breeding density reaches 10,000 catties! Generally speaking, 1 mu of pond polyculture is raised to 2000 3000 catties! Of course, there are also big differences in region, climate, environment, water quality, breeding technology and input.

Grass carp is one of the four large fish, which is large and is bred in various places. How many grass carp can be raised in 1 acre of fish pond with a water depth of 1 meter?

1 mu can generally raise 300-400 grass carp, which should be determined according to the fat and leanness of the water body and the feeding mode. If the water body is relatively fat, you can mainly use silver carp with 100-120 grass carp, and if the water body is thinner, you can use grass carp as the main body with silver carp.

Grass carp is the mainstay, 1 acre is stocked with 400-600 grass carp, 20 acres are put about 12,000 fry, plus other fry, a total of no more than 20,000 fry.

If the size of grass carp stocking is 200 250 grams, 20 acres can be stocked with 10,000 grass carp. The water depth is left and right, with two aerators and one feeder.

For the big head, you can put 600, 50 to 60 per acre of water surface is enough, and grass carp should not exceed 300 per acre

How many fish fry can be placed on more than 20 acres of water surface? Fry of 10 kg to 25 kg should be placed.

One acre of pond can raise 800-1000 grass carp. The breeding density should not be too large or too small, the density is too large, its growth is too crowded, it is easy to affect its growth and development, and the density is too small to obtain the maximum benefit. Cultivated grass carp can be made into formula feed with 50% straw, 5% rice bran bran, 15% soybean cake, 5% fish meal, 1% bone meal, and 1% salt and vitamin additives, and then fed.

60 acres of reservoir can raise 600 grass carp

It is recommended to put more than half a catty of fish, the survival rate is high, a catty can be weighed 6-8, but the survival rate is low, and can not be out of the pond that year, 50 acres of reservoir main grass carp, about 600 of about one acre and a half catty, about 300 catties, ** at present per catty, is expected to be 2000 yuan, each mu with bighead carp half a catty about 200, about 400 yuan, per mu with carp half a catty about 100, about 200 yuan, herring or black mixed half a catty about 50, about 200 yuan, In this way, about 3,000 yuan is put into one acre of fish pond and about 150,000 yuan for 50 acres.

Put 6-8 per catty, about 7-80,000!

How many fish can be sampled in one acre of land polyculture, mainly grass carp, with a water depth of 2 meters.

Hello, if it is mainly for grass carp farming, 400-600 grass carp can be stocked per acre, and then 200 silver carp and 50 carp can be mixed with polyculture. The specific amount of fish that can be polycultured depends on the breeding conditions, the species of fish, etc. It should be noted that the fish species with the same diet and inhabiting water layer are not suitable for polyculture in the same pond, and the proportion of polyculture fish is generally 40%-45% of pelagic fish, 30%-35% of pelagic fish, and 25%-30% of demersal fish.

1.How many grass carp can be raised on an acre of water surface, and how to raise them quickly and big.

How many grass carp can be raised on an acre of water surface, and how to raise them quickly and big.

Generally, 2,000 per mu are raised.

Raising conditions: It depends on the geographical environment, the surrounding environment, the pond environment, whether there is live water for water exchange, whether there is an aerator, whether to feed and grass, whether to polyculture other fish, generally polyculture will not exceed 500, simple grass carp may exceed 2000. Specific classification:

The stocking density of grass carp should be determined according to the planned production, and large, medium and small polyculture is generally adopted, of which large grass carp fingerlings are 500 to 700 g per fish, medium size is 150 to 250 g per tail, small size is 20 to 50 g per fish, and large size grass carp fingerlings are stocked 80 100 grass carp, medium size 120 grass carp, and small size 200 grass carp fingerlings.

Summary. Dear, hello, I'm happy to answer for you, I'll answer for you, rest assured<>

The normal fish farm can raise 1,350 domestic fish per mu (about 2 adult fish per square meter), then 20 acres can raise a total of 27,000 adult fish, and the 20 acres of fish pond can be used for the breeding of adult fish all year round. It can be polycultured with four large fish, which is conducive to fishing. You can raise 30% crucian carp, 20% crucian carp, 25% grass carp and 25% silver carp, so that fishing is more abundant.

Fishing ponds can be kept full and cultivated all year round, so that the fish are easier to fish! Please review!

How many one-and-a-half-pound grass carp are put in a fish pond with a depth of one meter and five water depths in 20 acres.

Hello dear, the following supplement is the expansion information I found for you. Generally speaking, no more than 20,000 fish are stocked in 20 acres of fish ponds, and the specific number needs to be determined according to the type of fish. If you breed grass carp, you can breed 1600-2000 fish per mu of fish pond.

If the stocked grass carp weighs about 80 grams per tail and the size is about 1 year old, 1,200 can be farmed, and then 4,000 chain fish fry and bighead carp fry can be farmed. The density of farmed fry is too large, resulting in overcrowding of fry, which will affect the growth and development of fry. The stocking density is too small, and it is easy to start the sedan car like a source.

If the frying is too much feed, the fry will not be able to eat, and it will accumulate at the bottom of the pond, affecting the water quality. It is necessary to reasonably control the amount of feeding and sail stoves to avoid water pollution.

Hello dear, the following supplement is the expansion information I found for you. One acre of water depth of the fish pond Shendong refers to can raise about 400 grass carp, different water bodies have fat and thin, the proportion of fish is also different, if the water is abundant, silver carp can be the main species, there are 120-150 fish, 25-30 bighead carp, 100-120 grass carp and 12-20 carp wide match, if the water is thin, grass carp should be the main species, 150 fish per mu trembling tong, silver carp 100, bighead carp 50, carp 20.

Summary. Put about 8 grams of grass to grow fish per acre, and 128 fry can be placed.

Put about 8 grams of grass in one acre to grow fish, and you can put a few fry.

Put about 8 grams of grass carp fry in one mu to raise fish, and you can put a few fry.

Put about 8 grams of grass to grow fish per acre, and 128 fry can be placed.

I'm only a meter deep.

Halving it. Sixty 70

The normal water depth is 2-3 meters, and you halve this meter to 60-70 bars.

What should I pay attention to when feeding grass carp?

1. Forage selection: Feed grass carp to provide ryegrass, Sudan grass and other tender forage, reduce the amount of forage with less fiber content. 2. Feeding method:

When the body length of the grass carp is less than 5 cm, it is fed 2-3 times a day, and when the body of the grass carp is more than 5 cm, it is fed 1-2 times a day. 3. Water quality management: keep the water temperature between 20-32 degrees, and change the water once a week.

Grass carp mainly feed on grass plants, in the process of feeding, you can make a forage feed such as ryegrass and Sudan grass, and choose fresh and tender grass with less fiber content to feed, so as to avoid grass deficiency fish can not digest food, and when terrestrial aquatic plants are abundant, it is necessary to reduce the amount of pure feeding of aquatic aquatic plants, so that grass carp can grow vigorously.

When feeding grass to hold fish, it is necessary to determine the amount of feeding and feeding times according to the body length, when the body length is less than 5 cm, provide earthworms, egg yolks, mealworms and other feeds, feed 2-3 times a day, when the body is longer than 5 cm, provide fresh and tender forage, feed 1-2 times a day.

Grass carp has higher requirements for water temperature and water quality, in the process of breeding, the water temperature should be kept in the range of 20-32 degrees, to avoid grass carp being frozen or heated, poor growth, and grass carp likes dry finger to rise to clean water quality, can change the water once a week, and the amount of water exchange is a quarter of the total amount of the whole pool. Only the old.
