How many fish can be produced in an acre of fish pond, and how many fish can be raised in an acre of

Generally, the mu does not exceed 800 1000 catties.

It mainly depends on how you raise the water and what kind of water the source is. It can be roughly divided into extensive stocking, semi-intensive and intensive breeding. Extensive one acre of land can also produce 10 catties to 30 catties, semi-intensive farming method is generally not more than 800 1000 catties per mu, intensive farming method to be on the aerator, the yield per mu can reach several thousand catties.

However, semi-intensive and intensive farming are fed, and the yield is also related to the quality and quantity of feeding. According to you, the pond should be a high-yield pond if it is intensively cultivated, but I don't know if it can be drained. Generally, the stocking of fry mainly raises carnivorous fish and omnivorous fish, but they are all combined with filter-feeding fish to purify the water quality.

Filter-feeding fish generally have a proportion of 20-30%. Your pond is clear, and filter-feeding fish should be spared.

Extended Information: Daily Management of Fish Ponds:

1. Strengthen pond patrols: pay close attention to the eating conditions and activities of fish. Especially in thunderstorms.

or hot weather, to avoid the occurrence of dead fish in the pond.

2. Control density: should do a good job of rotation fishing, catch large and keep small, and balance the market, so as not to induce various diseases caused by excessive fish carrying capacity in fishing ponds during the rainy season.

3. Take care of inputs: the rainy season.

Inputs such as feed, fishery medicine, and fertilizer are highly susceptible to mildew, and these inputs should be kept in a dry and ventilated place, and expired compound feed or drugs should not be used.

4. Other management work: do a good job in breeding logs and improve three records. It is also necessary to do a good job in flood prevention, drought prevention, evasion, and theft prevention, so as to ensure that nothing goes wrong in all links.

One acre of fish pond can raise no more than 1,000 fish。However, it is also divided into fish species, such as grass carp, 1 mu is stocked with 400-600 grass carp, and 200 silver carp. 50 carp.

You can feed grass carp pellets without being too dense.

1. Stocking large-sized fish fingerlings is a high-yield measure for pond fish farming. Large-sized fish species have the characteristics of strong disease resistance, high survival rate and rapid growth.

2. Under the condition of pond feeding, grass carp is generally stocked with fish fingerlings weighing kilograms, and after 4 months of feeding to autumn, it can reach the size of kilograms, such as stocking kilograms can grow to kilograms.

Silver carp is generally put into one-year-old fingerlings, 12-8 cm in size, and can reach kilograms when it comes out of the pond. Other fish such as carp, crucian carp and bream are stocked with yearling fingerlings, the density is a little thinner, the size is about 12-14 cm, after a few months of feeding, the carp can reach the size of 05 kg, crucian carp 100 grams or more.

Comprehensive disease prevention. 1. Strengthen prevention: In the early stage, when the weather is fine, you can use insecticides to splash once to kill the parasites of water and fish, and then use disinfectants to sterilize every 2 days. And add drugs to the feed to prevent the occurrence of diseases.

At the same time, pay attention to regular disease prevention, and splash with quicklime, copper sulfate and ferrous sulfate mixture, dibromohydantoin, chlorine dioxide and other drugs every month.

2. Comprehensive**: The main fish diseases in the rainy season are fulminant hemorrhagic disease, erythroderma, gill rot, hepatobiliary syndrome, ring worm, sporidiosis, etc. Normally, when a fish disease occurs, the first thing to do is to kill the insect.

At the same time, the water body is disinfected, and the antibacterial bait is taken internally for prevention and control. After the condition is stabilized, the pond water is adjusted to a weak alkaline with quicklime to facilitate the growth of fish.

Summary. If the local water quality conditions are relatively good, the number of farmed fish can reach 5,000 catties, and the water depth of the fish pond is best to be more than 2 meters, if the water depth is shallow, it will lead to the bottom temperature is too high and the light is too strong, so that the probability of fish death increases.

How many fish can be raised in an acre of fish pond.

An acre of fish pond can raise 3500-4000 kg of fish, before putting the fish fry, the fish pond needs to be disinfected, you can splash bleaching powder or quicklime in the fish pond, and the fry is best mixed and matched, which is conducive to improving the survival rate of fish, when feeding the fry, it is necessary to feed the bait 3 times a day to meet the nutritional needs of the fish.

If the local water quality conditions are relatively good, the number of farmed fish can reach 5,000 catties, and the water depth of the fish pond is best to be more than 2 meters, if the water depth is shallow, it will lead to the bottom temperature is too high and the light is too strong, so that the probability of fish death increases.

An acre of fish pond can raise 3500-4000 kg of fish, before putting the fish fry, the fish pond needs to be disinfected, you can splash bleaching powder or quicklime in the fish pond, and the fry is best mixed and matched, which is conducive to improving the survival rate of fish, when feeding the fry, it is necessary to feed the bait 3 times a day to meet the nutritional needs of the fish.

1. Breeding quantity

An acre of fish pond can raise 3500-4000 kg of fish, if the local water quality conditions are relatively good, the number of fish can reach 5000 kg, and the water depth of the fish pond is best to be more than 2 meters, if the water depth is shallow, it will lead to the bottom temperature is too high and the light is too strong, so that the probability of fish death becomes larger.

2. Disinfection treatment

When breeding fish fry, you need to disinfect the pond first, you can splash quicklime or bleaching powder on the bottom of the pond, and then mix it with the silt at the bottom of the pond with tools to eliminate the bacteria and parasites in the pond, so that the fish are infected and diseased, and wait for the sun to be exposed to the sun for 7-8 days, and then fill the pond with water.

3. Mix and match breeding

When stocking fish fry into the fish pond, it is best to mix and match culture, you can choose fish with strong adaptability and docile temperament, such as grass carp, silver carp, carp, bream, etc., before stocking, the fry should be soaked in the diluted potassium permanganate solution for 5 minutes, disinfected and sterilized, to avoid fish infection.

4. Feeding management

When raising fish, you need to feed them once a day in the morning and evening, and you can feed live bait such as small fish, small shrimp, loach, or concentrate feed such as fish meat sauce, soybean cake, egg yolk, etc., to meet the nutritional needs of fish, and it is best to plant aquatic plants such as aquatic plants in the pond to provide habitat and food for fish.

An acre of fish pond can raise about 1,000 fish, first of all, according to the water depth of the pond, water quality, management level, fish species, fishing methods, etc., experience is very important, and secondly, pond fish farming should be cleaned up before the fish fingerlings are put into the pond, and thoroughly disinfected. The water quality should also be clean, and there should not be too many aquatic weeds in it, because once the aquatic weeds rot, it will affect the water quality.

Don't exceed 850 fish, put more fish, be sure to have aeration equipment. Suppose there is an acre of fish pond, covers an area of 667 square meters, the water depth is three meters, the main crucian carp, want to match some grass carp to raise, you can take such a breeding structure: put 400 crucian carp (50 grams), 80 grass carp (about 300 grams), 100 silver carp, 50 fathead fish (silver carp), and then with some other fish.

The pond is generally required to be rectangular, east-west, with an area of 3-10 acres and a water depth of 1Rice. The bottom of the pond is flat, no silt or less silt, there are injection and drainage facilities, convenient inlet and drainage, fresh water quality and no pollution, pH value, and the pond is equipped with 1 3 kilowatt propelled aerator.

Chapter 1: Scientific stocking of fry in freshwater fish farming.

Fish fry requirements: the color, appearance, size and specifications are consistent, no disease and injury, and the mucus on the surface of the fish is smooth, lively and robust.

A: High-density farming.

Monoculture high-density seedling mantissa number: 1100 mu 2 aerators (specifications: winter summer flowers, adult fish fry).

Note: The number of fry should be reduced if the size is too large, according to the reduction of 6% to 15% per 1 kg of weight gain, and the water depth is required to be 1 meter 5 to 2 meters.

Mantissa of polyculture high-density seedling:

1 set of aerator, 550 acres (specification: 300 grams of summer flowers, tail mu (specification: 200 grams of summer flowers) 180 acres (specifications: 80 grams to 100 grams of summer flowers, tail mu (specifications: 300 grams of summer flowers).

Note: The above-mentioned requirements require that the number of fry is low and carp and other underground fish should be raised, otherwise it is easy to make the fish pond turbid, bighead carp and silver carp are not easy to interculture, and the water depth is required to be 2 meters to 2 meters 2

B: Low-density farming.

Mantissa of monoculture low-density seedlings:

700 acres 1 aerator (specification: 500 grams of 1-year-old foot fry).

Mantissa of polyculture low-density seedlings:

1 aerator 350 acres (specification: 300 grams of summer flowers (specifications: 200 grams of summer flowers) 100 acres (specifications: 80 grams to 100 grams of summer flowers (specifications: 500 to 1000 grams).

Note: 1, A, B two low-density stocking ratio can float up or down, the range of floating at their own discretion, the range should not exceed 13% to 28%, should not be interbreeding carnivorous fish, the first day of the fry should not be put feed and bait.

2. The stocking time of fish fry should be from January to March in winter, which is conducive to reducing disease and loss, and carnivorous fish should be selected from early summer from March to early May.

3. Stocking carnivorous fish can not be co-stocked with herbivorous fish of the same size and omnivorous filtered fish, must be interstocked with fish that are 1 times the body weight of carnivorous fish, stocked grass carp and carnivorous fish must be inter-stocked with scavenger fish (such as: silver carp, bream, bighead carp) is conducive to clean water quality and improve breeding efficiency.

4. The fish pond should be disinfected before putting the fish fry, and the fish fry must be soaked in cold water with potassium permanganate and salt for 15 minutes.

5. The above-mentioned summer flowers can be replaced with fish and 1-year-old and 2-year-old winter fry.

Technical extension: silver carp and bighead carp should not be intercultured, the number of carp should be kept as small as possible, interculture of crucian carp will help the growth of other fish, and interbreeding a small number of small-sized carnivorous fish will help eliminate trash fish.
