With some grass carp, how can I make the water in the pond fatter?

If we have some grass carp, we need to make the water in the pond fatter, we need to let the grass carp defecate in it, and feed it more food, and we don't need to change the water, so the water will be more fat.

If you want to make the water in the pond more fertile, you can put some chicken manure and duck manure into the pond.

First, we should feed more fresh and tender grass. Because the fresh and tender forage is rich in nutrients, less fiber, and easy to digest, it can make the grass fish grow faster, reduce the right to disease, and at the same time reduce the amount of feeding. It is best to feed artificially grown ryegrass, sultan grass, friendship alfalfa and other forages, as well as collected wild long-leaved grasses.

It is not advisable to feed grass carp with anorexic-like reticulated veins. It is also necessary to observe the grazing of grass carp. The grasses that like to eat should be fed more to meet the needs of grass carp growth and development.

The second is to reduce the feeding of aquatic aquatic plants. Grass carp can grow 1 kg of meat if it eats 15 kg of terrestrial aquatic grass; If you eat aquatic plants, you need to eat 60 kg to 80 kg to grow 1 kg of meat. The third is to feed different forages according to the different sizes of fish mouths.

Grass carp have a small mouth in the juvenile stage, and can not be fed coarse, hard forage, etc., should be fed sedges, duckweed, etc., or the tender long-leaf grass is crushed and fed. Later, as the fish gradually get older and the mouth of the fish also increases, they can transition to regular fresh forage. Fourth, the feeding method should be appropriate.

Grass carp should be fed regularly, sufficiently and evenly every day, and strive to spread the forage so that the fish can be full, eat well and eat evenly, so as to improve the breeding effect. It is also necessary to adjust the feeding amount according to the weather, water quality and fish activities to meet the needs of the fish for forage. It is strictly forbidden to feed forage that has been stored for too long and has rotted and deteriorated to avoid fish contracting diseases.

Mix for internal use:Sai has fish fat and fish beauty, mixed shake in the feed, after the fish eat can increase immunity, promote growth, and enhance the attractance.

The commonly used types of aquatic weed fertilizers are basal fertilizer, root fertilizer, liquid fertilizer, iron fertilizer, etc. The base fertilizer and root fertilizer are buried in the bottom and used in the sand, and the liquid fertilizer is directly poured into the water for use. In the usual breeding process, the rational use of fertilizer is one of the keys to raising aquatic plants.

1. Fertilize different aquatic weed varieties according to aquatic weed varieties. The demand for essential nutrients varies greatly, especially in the case of micronutrients. There is a certain correlation between the content of elements in aquatic plants and the demand of aquatic plants.

If you need a lot of iron, aquatic plants will also have a lot of iron in their bodies and have a strong tolerance to iron. Strictly speaking, each aquatic plant should have its own set of fertilizer formulas, but this is not realistic in life.

2. The type of aquatic weeds that are fertilized according to the type of aquatic weeds. It can be roughly divided into stemmed aquatic weeds, clumped aquatic weeds and attached aquatic weeds. Among them, the root cluster starvation system of clumping aquatic plants is the most developed, so the use of basal fertilizer will allow them to absorb nutrients more effectively.

3. Fertilize according to water temperature. The water temperature that grows most vigorously is 24 to 27 degrees, too high or too low will affect the intensity of photosynthesis, and also affect the absorption of nutrients by aquatic plants, so when the water temperature is too high or too low, the amount of fertilizer should be appropriately reduced to avoid the rampant algae.

4. Fertilization according to the supporting facilities for raising aquatic weeds If the grass tank has enough light, add carbon dioxide, and plant a full tank of fast-growing aquatic weeds, the amount of fertilizer should be increased, but pay attention to the algae situation and the growth state of aquatic weeds, so as to adjust the dosage in time.

<> use fertilizer water paste: the main components of fertilizer water paste are amino acids and trace elements that are easily and quickly absorbed by algae, if you want to make the fish pond quickly fertilize water, you need to apply 1-2 times of fertilizer water paste.

Use organic fertilizer: If you want to quickly fertilize the fish pond, you can use organic fertilizer, organic fertilizer can be taken from local materials, such as biogas slurry, you can put the manure into a well-sealed plastic bag and then place it in a dark place for fermentation.

Use amino acid fertilizer: Amino acid fertilizer has a good inhibitory effect on cyanobacteria, and the dosage is small and effective.

1. How to fertilize the fish pond

1. Use fertilizer and water ointment.

1) The main components of fertilizer water paste are amino acids and trace elements, which are very easily absorbed by algae.

2) If you want to make the fish pond fertilize quickly, be sure to apply 1-2 times of fertilizer paste to make the water more fertile, promote the growth of algae, and provide food for the fish.

2. Use organic fertilizer.

1) If you want to quickly fertilize the fish pond, you can use organic fertilizer, which can be taken from local materials, such as biogas slurry and various fermented manure.

2) Then put the manure into a well-sealed plastic bag, and then place it in a dark place for fermentation, and be sure to ensure that the organic fertilizer is completely decomposed before that, so as to avoid parasites in the fish pond.

3. Use amino acid fertilizer.

1) Amino acid fertilizer has a very good inhibitory effect on cyanobacteria, and the dosage is small and effective.

2) There are three main types of amino acid fertilizer, namely powder, paste and liquid, if you want to quickly fertilize the fish pond, you can use paste amino acid fertilizer, because its fertilizer durability is better than liquid and the durability is stronger than powder.

2. Matters to be paid attention to when raising fish

1. Thoroughly clean the pond and disinfect it, and apply plantar fertilizer at one time.

1) Before the fish are put into the pond, the drainage channel must be dredged to remove too much silt in the pond.

2) When the water depth reaches 20cm, each mu of fish pond can be disinfected with 100 kg of quicklime water to kill pests, bacteria and microorganisms, and then apply 500 kg of rotten human and animal manure as base fertilizer.

3) Then store the rice, wait for 1 week after the medicinal properties disappear before releasing the fish.

2. Reasonable combination of polyculture, the implementation of three-dimensional fish farming.

1) If you want to make full use of the water space and natural bait, you must breed "fat water fish" such as silver carp and tilapia and "eating fish" such as grass, carp and bream according to the upper, middle and lower water layers.

2) 1200-1500 "catty and two fish fingerlings" can be stocked per mu, of which grass carp mainly accounts for 40%, silver carp accounts for 40%, carp, crucian carp, bream and tilapia account for 20%, and the total stocking amount per mu can reach about 150 kg.

3. Sprinkle drugs in turn to prevent and treat fish diseases in a timely manner.

1) During the high temperature period, 10 kg of quicklime must be used every half a month per mu, or 250-350 grams of 90% crystal trichlorfon slurry must be used to sprinkle the slurry, and at the same time, bleaching powder or copper sulfate and ferrous sulfate medicine baskets can be hung on the floating bait table of fish for food field disinfection.

2) In the epidemic season of grass carp enteritis, every 100 kg of grass carp can be mixed with bait and fed with kilograms of garlic head, and grass carp enteritis can be prevented by feeding for 3-6 days.

Summary. There are many aquatic plants that are suitable for planting in fish ponds, such as bitter grass, curly-leaved dragon's beard grass, crown grass, and so on. There are also some aquatic plants that are not aquatic weeds but can be kept in water, such as cow hair grass.

Aquatic plants have three functions, one is to provide food to fish, the second is to provide shelter for small fish to avoid being eaten by large fish, and the third is to purify water quality.

There are many aquatic plants suitable for planting in fish ponds, such as bitter grass, curly leaf buried dragon beard grass, crown grass and so on. There are also some aquatic plants that are not aquatic weeds but can be kept in water, such as cow hair grass. Aquatic plants have three functions, one is to provide fish with liquid as food, the second is to provide shelter for small fish to avoid being eaten by big fish, and the third is to purify water quality.

1. What aquatic plants are raised in the fish pondThere are many aquatic plants raised in the fish pond, such as duckweed, water lily, pinny grass, wattle, gourd and so on. The benefits of planting aquatic plants are many, it can not only improve the overall ornamentality, but also carry out photosynthesis, thereby releasing a certain amount of oxygen socks, and can also absorb some waste in the water as nutrients for its own growth, which has a certain role in maintaining water quality, but it is not that the more you plant, the better. 2. Which aquatic plants are easy to raise 1. Moss:

Moss aquatic plants are the most common negative aquatic plants, and the biggest feature is that they are less dependent on light, so they can grow healthily even in a shady environment. Also, because it is a bryophyte, it does not have real roots, such as clinging to stones or sunken wood. 2. Water Banyan Tree:

Banyan is a water-standing plant, with a height of about 10-15 cm, native to the western region of Africa, suitable for growing in tropical freshwater waters, with certain requirements for water temperature, usually higher than 15 to survive the winter. This plant is generally used as a foreground grass, and its leaves are relatively large. 3. Iron Crown:

The scientific name of the Iron Crown is the Winged Star Bright Fern, which is a fern that prefers shade and dampness. Its height is about 15-30 cm, which can not only be used as a water plant, but also can be planted on land, and the effect of using rockery is also very good.

1.Pond requirements: The pond area should be 10-20 acres, the water depth is meters, and the thickness of the silt is not more than 20 cm. Every 10 acres of ponds are equipped with 1 aerator with a power of 3 kilowatts and an automatic feeding machine. Grass carp.

2.Pond cleaning: Drain the pond water in winter and freeze it for more than 20 days. 15 days before stocking, 10-20 cm of water is inlet and 150 kg of quicklime per mu is used for disinfection in the pond.

3.Fingerling stocking: Before and after the Spring Festival, 300 grass carp fingerlings with a size of 200-250 grams per mu, 300 crucian carp fingerlings with a size of 15-20 kilograms, 50 silver carp fingerlings with a specification of 5-6 kilograms, and 10 bighead carp fingerlings.

Fingerlings are disinfected by soaking in 5% salt water for 5-10 minutes before stocking.

4.Feed feeding: mainly feed pellet feed, feed protein content in 28-32%, supplemented by green feed.

Feed feeding follows the principle of "coarse before fine" and "four fixed and four looks", generally fed twice a day, to eat within 2 hours, grass carp 8 into full is appropriate. After continuous feeding of pellet feed for a period of time, the pellet feed should be stopped for 1 week, and the raw grain feed should be fed during the interval period. Usually pay attention to adding vitamins and other drugs to the feed to avoid grass carp suffering from hepatobiliary syndrome and other diseases and causing a large number of deaths.

5.Water quality management: correct use of aerator, sunny and windless weather from June to October, start the aerator for 2 hours at 1-3 p.m. every day, and increase aeration in the early morning; Continuous cloudy days should be increased with oxygen early.

Add new water to the pond in a timely manner, and gradually regulate the water quality by adopting the method of "small discharge and small intake, and multiple water changes". From June to September, add new water every 3-5 days, add about 10 cm of water each time, and splash 10-20 kg of quicklime with 10-20 kg of quicklime in the whole pool every 15-20 days.

6.Disease prevention and control: the method of "combining coarse and fine and green in the front" is used to control the occurrence of grass carp hepatobiliary syndrome.

Common diseases of grass carp include erythroderma, gill rot, enteritis, and generally take the best method of combining internal and external splashing, and external pouring is mainly based on disinfectants such as bleaching powder and chlorine dioxide, which are used for 3 days; Oral administration with "three yellow powder" bait effect is better, every 50 kg of fish weight with three yellow powder (rhubarb 50%, cork 30%, skullcap 20%, crushed into powder and stir well) kg and flour paste mixed into the feed feed, for 3-5 days.

7.Timely fishing: It is an important measure for grass carp to be harvested and marketed in a timely manner, and the main purpose is to reduce the fish carrying capacity of the pond water body and promote the rapid growth of pond fish in the later stage. It is usually caught once at the end of July, and in the early morning when the water temperature is low.

10 acres of water surface, 1,5 meters deep, how many grass carp can be raised?

1. Use basal fertilizer and root fertilizer. According to the instructions, the base fertilizer and root fertilizer are stuffed into the bottom sand at intervals. Generally, fertilization can last for 3-6 months at a time.

2. Use liquid fertilizer. Use a syringe fertilizer applicator to pump out the liquid fertilizer quantitatively, mix the water in the fish tank, and evenly inject it into the aquatic plants around the fish tank. Follow the instructions to apply fertilizer once a week or every day.

Fish out all the fish, replant the aquatic weeds, and bury the aquatic weeds directly into the sand bottom when planting, so that you don't need to fertilize the aquatic weeds for a year.

Aquatic plants do not need to be fertilized, they grow on nutrients in water, and they need the photonucleus action of sunlight.

The syringe irrigates the root fertilizer into the roots of the aquatic plants, and you must pay attention to the thin fertilizer applied frequently!

Regardless of whether the bottom fertilizer has been added or not, proper topdressing is very important for planting good aquatic plants. There are two types of common topdressing for aquatic weeds: root fertilizer (long-acting fertilizer) and liquid fertilizer (fast-acting fertilizer). As long as the products of regular manufacturers are used in accordance with the instructions, they will not cause adverse effects to other organisms in the tank.

The principle of topdressing in the grass tank is as follows: soon after the tank is opened, do not fertilize the plant before taking root, the plant can not absorb, but burst algae. Root fertilizer is buried near the root system of aquatic plants.

Liquid fertilizer is best injected near the root system with a long syringe. Plants tied to sunken wood and stones can be diluted with liquid fertilizer and sprayed with a syringe on the surface. Fast-acting fertilizer should not be applied within two hours before turning off the lights.

Bottom fertilizer is the fertilizer that is laid on the bottom layer at the beginning of the opening of the tank.

In your case, you can choose liquid fertilizer, and the effect can also be.

Some need to add carbon dioxide.

Proper lighting is a must.

Aquatic plants need to photosynthesize to grow well!

Fish pond fertilizer can be used as food processing scraps such as grass, livestock manure and distiller's grains.

The water temperature in spring is low, and the nutrients in the water body (nitrogen. Phosphorus. potassium, etc.), the number of beneficial algae in the water body is low, which makes it difficult to fertilize the water body in spring.

In some ponds, there will even be a phenomenon of thin water and green moss at the bottom of the pond. In view of the special climate and water environment in spring, after test verification, Zhengyu Company has made the following plans:

1. The pond water is thin, the first time the pond is watered, and no fertilizer measures have been used, the use of Feibao + fertilizer is fast, according to the description of the maximum dosage, use on sunny days, can not add water, the effect is obvious, two days effective.

2. The pond water is thin, turbid, the first time the water is inflowed, and the pond has not used any fertilizer and water measures: first use the bottom double change, 8 acres of bags, adjust the water quality, and then the same as above.

3. The pond water is thin, the transparency is high, and the pond has moss: 2 kg of blue alum per mu of fish pond, 3 kg, 20 kg of water, spraying between the pools. Generally, moss can be removed within 5 days. However, the amount of blue alum should not be too much, so as not to kill the fish and cause unnecessary losses.
