How to raise ornamental grass carp and precautions just bought back

Put the salt water in a ratio of about 5 thousandths, and generally put it for about 10 to 15 minutes. If you can't grasp this concentration, it is recommended that you do not need to sterilize, first put it in the basin for a week or so, and see if there is anything wrong with the fish, if not, you don't need to sterilize, just put it in the tank. You don't need to change the water too often, and don't change it all at once when changing the water, use a spoon or scoop to scoop out one-third of the water, and then inject one-third of it.

It is recommended not to catch fish with a net, but directly with a scoop and spoon. Another thing you should note is that if you use tap water to raise fish, if you don't have tablets like baking soda, the tap water should be dried for at least 2 days!! Otherwise, the chlorine in the tap water will kill the fish.

Goldfish as an ornamental fish is actually very easy to raise, if you have no experience, go to buy 2-year-old fish to raise, this age of fish is relatively adaptable.

There is also a method of relying on people to raise it, I recently raised it like this Buy a bathtub and put it on the balcony, plant some aquatic plants, and when the water is a little green, wrap the chicken with gauze and hang it in the water with a rope, so that you don't need to change the water for several years. If you don't like this lazy feeding method and want to keep the water clean, you can buy a few snails and put them in the water, which will obviously help to improve the water quality and improve the clarity of the water. If you want to be a little more professional, go for gas mercury and filtration.

Hehe, congratulations, if you raise undead fish for 2 weeks, you will slowly have a fever The fever is fascinated, haha. I wish you success!! It is recommended that you go to China Lanshou.com, where you will find all your answers.

1.Disinfect the fish tank thoroughly, mix it with potassium permanganate and tap water, soak it for 2 hours, and then change it to clean water and wash it for later use. The color of potassium permanganate water can be adjusted to purple, not dark purple.

2.Trapped water, put tap water into the trapped water container and use an oxygen pump to oxygenate for 24 hours, so that the chlorine gas can drift away.

3.Place the sterilized fish tank with a filter, add trapped water and let it stand for three to seven days.

4.Just bought fish bucket calendar guess to pass the water, first buy back the fish-based type together with the plastic bag soaked in the fish tank for 20 to 30 minutes, and then continue to soak the plastic bag in the fish tank, at the same time pour the water in the newly opened fish tank into the plastic bag containing the fish, the water is one-third of the water in the plastic bag, after 20 minutes or half an hour repeat the previous step, repeat three times, add a third each time, 20 minutes or half an hour between each rotten suspicion, and then pour out the water in the plastic bag, put the fish into the fish tank.

5.Rest for three days, do not feed, and change one-third of the water after a week after releasing the fish.

1. Seedling management. Breeding grass carp, need to put the fry in the spring, splash the whole pond with quicklime or bleaching powder before the seedling, can kill the bacterial sore and virus, reduce the risk of disease of the grass carp fry, the fry should be selected to be strong and fat, the body surface is covered with mucus, slightly golden fry fry, the use of permanganate potassium solution to sterilize and disinfect the grass carp fry, the time of putting it as far as possible to choose in the morning of a sunny day. In the process of grass carp fry, ryegrass needs to be cut into centimeter segments, which is conducive to the feeding of fry.

2. Breeding management. Grass carp in the growth process, prone to bacterial infection and various diseases, need to do a good job of prevention and control measures, if the green feed is also mixed with bacteria, after intestinal digestion and absorption, there will be a slight enteritis, coupled with various bacterial infections in the water body, let no Li Hua flea, fish lice, water mold spores, bacterial hemorrhagic disease, etc., so every summer, to splash the whole water area of the first enteritis and bacteria to kill the drug.

3. Observe regularly. In the process of breeding grass carp, the water quality should be observed regularly, and the grass carp feces floating on the water surface should be analyzed, and the grass carp feces are floating in the pond, indicating that the grass carp eat normally, if the grass carp has a disease, it will reduce eating, and it is necessary to find the cause for timely prevention and control.

4. Water quality management. After all the green fodder is fed, all the leftover grass carp needs to be salvaged ashore, and it must not be allowed to sink to the bottom of the water, otherwise it will rot and deteriorate and breed bacteria and viruses, so as to ensure that the water quality is clean. It is also necessary to splash bleaching powder regularly, and wait until autumn to carry out a second splash of bleaching powder to ensure a clean growing environment for grass carp.

Grass carp is a common freshwater fish with high nutritional value and rich in nutrients such as protein, vitamins and minerals. If you want to improve the quality of grass carp farming, you can start from the following aspects:

1.Water quality control: Grass carp has high requirements for water quality, and the water quality should be kept clean, stable and suitable. Control water temperature, pH value, dissolved oxygen and other parameters, regularly change water and clean sediment.

2.Feed management: Choose high-quality feed and feed it in moderation to avoid overfeeding and wasting feed. At the same time, it is necessary to control the feeding amount and feeding time to ensure the satiety of grass carp.

3.Disease prevention and control: Regularly check the health status of grass carp, detect and deal with diseases in time. Methods such as drugs and water quality regulation can be used to prevent the occurrence and spread of diseases.

4.Environmental management: Grass carp is more adaptable to the environment, but it also needs a suitable growth environment. It is necessary to pay attention to the management of water ventilation, light, water flow, etc., to provide a comfortable growth environment for grass carp.

In short, if we want to improve the quality of grass carp farming, we need to pay attention to water quality control, feed management, disease prevention and environmental management, and quickly implement scientific and standardized aquaculture management.

The survival of everything in the world needs a certain material basis to maintain the characteristics of life, people need to breathe air, and fish need water, and fish without water is like people without air, it is difficult to survive. Therefore, it can be seen that water is very important for fish, so we should do our homework on the selection of water for fish farming when raising fish. <>

1. Clean water resources should be selected for raising grass carp

Water is very important to the fish, is the water of life of the fish, if there is no water, the fish will not survive, so when we raise grass carp, we should choose clean and pollution-free water resources for its water. Because the water of fish farming is just like we humans need to breathe air, if we breathe polluted air, it will cause certain harm to our body, so the same is true for fish farming, we need to choose water resources that are not polluted, so as to better let the fish grow healthily, and clean water will make the meat of the fish more delicious and delicious. <>

II. II. IIThe water for raising grass carp should choose water resources with high nutrients

People who raise fish know that the main food of fish ** is when swallowing water, by absorbing nutrients in the water to provide for their own body needs, so we can know the nutrients in the water, the substance is very important for the life of the fish, if the nutrients in the water are low, then it is very for the fish body needs, so it will lead to a lot of fish because of hunger and death, so the grass carp is not successful, so we want to raise grass carp, we should choose water resources with higher nutrients. <>

3. Grass carp should be raised in a highly mobile water environment

We all know that water has strong fluidity, and the fluidity of water not only brings air to the fish, but also brings certain nutrients to the fish, but if it is a closed pool, then it is difficult for the water to flow, and the air nutrients in the water will be greatly reduced, which will lead to the threat of fish life, so we should choose a water environment with strong mobility when raising grass carp.

Fourth, grass carp should choose a water environment with green plants

The place where the fish survive is relatively closed, so it is difficult for them to go to other places to find their nutrients, so when we raise fish, we choose a place with green plants in the environment of fish farming, so that when we raise fish, the green plants can be eaten by the fish, and can also play a certain aesthetic role.

You can choose according to your own experience, or it can be chosen based on the size of the pond, paying attention to the composition of each fish grass.

When raising grass carp, you should choose some excellent fish roe, you should prepare some high-quality water, put some seaweed in the water, you can also put some seaweed, you should do a good job of sun protection, and you should also do a good job of preventing escape when raising fish.

Be sure to choose water with good quality, but also maintain oxygen in the water, and then change the water regularly.

You can connect the tap water, and then let it sit for a while before pouring it into the grass carp water to mix it, so that the grass carp may survive better in this water.

If you are feeding ornamental fish for the first time, try to buy goldfish of a survivable species. These goldfish are easy to feed and survive for a long time, making them easy to raise.

Change the water in the fish tank in time. The water in the fish tank should be replaced on time to ensure that the water quality is clean. Pay attention not to change all the water at once when changing the water, so it is difficult for the fish to adapt to the new water quality, water temperature, etc., which can easily lead to the death of the fish.

Clean up the excrement of ornamental fish in the fish tank regularly to ensure the cleanliness of the fish tank. The waste excreted by ornamental fish is heavily polluted to water quality and is prone to bacterial growth. It is necessary to clean up the excrement at the bottom of the water in time to ensure that the living environment of ornamental fish is good.

If possible, you can install a filter device, which is more convenient.

Choose the right feed and pay attention to the frequency and method of feeding. To buy fish feed, we should choose products of qualified quality produced by regular manufacturers, so as to ensure that the fish are easy to digest and absorb after eating the feed and do not get sick. When feeding the feed, it should be noted that it is generally about 3 times during the day and every 6 hours.

Try to feed as little as possible at night.

Ensure oxygen in the fish tank**. If you want to ensure that they survive for a long time, it is best to install an oxygenation device to ensure the oxygen in the fish tank**.

A certain number of aquarium fish are placed according to the size of the tank. Aquarium fish need a certain amount of space to survive so that they can move freely. Therefore, according to the size of the fish tank to decide how many ornamental fish to place, generally 100 liters of water fish tank can raise 10-15 fish.

Put some stones, aquatic plants, and the like in the fish tank. The growth of aquatic plants can provide a certain amount of oxygen for ornamental fish and also purify the water source.

Grass carp breeding method: Grass carp artificially bred broodstock are mainly used in original seed farms, rivers, lakes and reservoirs. **Broodstock in natural water bodies are selected by large-sized grass carp, and grass carp with normal body color, intact fin scales, no injury or disease, lively swimming, and strong physique are used as reserve broodstock, and then induced labor after intensive cultivation.

**Broodstock in captive culture are usually healthy grass carp that have reached sexual maturity and are in the reproductive age of ponds or ponds. In the process of collecting and transporting broodstock, care should be taken to select nets and tools to avoid injury to the fish.

In the past, conventional grass carp were mainly polycultured, which can only be cultivated in 3 years, with high cost and long capital occupation. The pollution-free grass carp high-yield, high-efficiency and rapid breeding technology is introduced as follows.

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 farming 2Pond Cleanup:

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.
