What to pay attention to in fish farming 5, precautions for fish farming

There are many precautions for fish farming, first of all, it is better to change the water frequently, usually it is better to change it once a week, and change a quarter of it each time. The second is to pay attention to the amount of food to feed, so that a small amount of food is done many times, which is conducive to its growth, and it will not spoil the water. At the same time, we should also pay attention to the water temperature, tropical fish must be raised with 20-30 warm water, and the fish tank should be cleaned regularly to discharge the dirt to ensure that the environment in the tank is clean and tidy.

1. Change the water. The first thing to do in fish farming is to change the water. Because the water body of the fish tank is limited, the water quality will deteriorate over time, and although the water looks clear, there are many harmful substances, which will increase the risk of fish getting sick, and may also affect their development. Therefore, it is necessary to change the water regularly, usually once a week, and the water quality is maintained well, or it can be changed once every half a month, about a quarter each time.

2. Feeding. Fish need to be fed, usually artificial feed, this kind of nutrition is balanced, which is very helpful for the development of fish. It should be noted that although the fish has strong hunger tolerance, it cannot be fed once every long time, and must be fed frequently, two to three times a day, but the amount of feeding each time should not be too large, which is not only conducive to its growth, but also not easy to spoil the water.

3. Temperature. Many common ornamental fish are tropical fish, such as guppies, swallows, arowana, etc., and they must pay attention to controlling the water temperature, as too low a temperature will affect their feeding and even lead to their death. Usually the water temperature should be kept between 20-30, although some fish can tolerate low temperatures, it is best not to fall below 18.

Fourth, clean up. The fish tank must be cleaned regularly, usually once a month. Cleaning the fish tank is mainly to discharge the dirt in the tank, and at the same time remove the scale and algae on the tank wall. Be sure to remove the fish before cleaning and prepare fresh water that has been trapped so that you can continue to raise fish after cleaning.

First brush the fish tank with a high concentration of potassium permanganate (available in pharmacies), wash it with clean water, soak it in the whole tank with a low concentration of potassium permanganate for two days, wash it with clean water, put it in tap water, and put it like one thousandth of a salt (sold in the fish market), note, one percent to five percent of the amount of medicinal baths said on the Internet, don't make a mistake, and then the water should be put for more than three days, and you can buy fish back after three days.

Water is essential for fish. When changing the water, don't add tap water directly, tap water usually contains chlorine, and we boil the water before drinking it to remove chlorine. Of course, the water used to raise fish is also chlorinated.

Let the tap water settle there for at least 24 hours, and it is better to be exposed to the sun, and it is better to leave it for two or three days. The temperature of the water is also very important, especially for tropical fish, which is even more delicate, and it is absolutely not possible to use too cold water, and ensure that the water temperature difference is less than 2 degrees when adding water to it.

Water farming: Before raising fish, water should be raised, and the water should be disinfected and dechlorinated. Feeding:

When raising fish, it is necessary to ensure that the food is sufficient and that the food is fed in moderation. Try not to feed at night and on cloudy days. Change the water:

When raising fish, it is necessary to ensure that the water is clean and change the water regularly. Do not change too much water each time, and do not change the water temperature and water quality too much after changing the water. Polyculture:

When raising fish, do not mix lightly. It is recommended to choose fish polyculture with similar habits and docile personalities.

1. What matters need to be paid attention to in fish farming.

1. Water raising: water should be raised before fish farming. Ordinary tap water cannot be put into use directly.

Water is disinfected and dechlorinated. Disinfection can be done with relevant drugs or with specialized salts. Chlorine can be removed by exposure to the sun or by standing.

It is also necessary to add nitrifying bacteria to the water and establish a nitrifying bacteria system to treat the excrement of fish in the water.

2. Feeding: Ensure that the food is sufficient when raising fish. Pay attention to the appropriate amount of feeding, and the amount that can be eaten within 5-10 minutes of each feeding. The frequency of feeding should be determined according to the appropriate amount of fish raised. Try not to feed at night or on cloudy days.

3. Change the water: When raising fish, it is necessary to ensure that the water is clean and need to be changed regularly. The frequency of water changes is determined according to the habits of the breed raised.

Generally, it should be changed every 7-10 days. Do not let the water temperature and water quality change too much every time you change the water. In addition to ensuring the cleanliness of the water, it is also necessary to ensure the oxygen content of the water.

4. Polyculture: Do not easily polyculture when raising fish. Some fish are not polycultured, and if they are polycultured, they may fight or die. It is recommended to choose fish polyculture with similar habits and docile personalities.

1.In the case of filtration, your fish tank is suitable for 30 small fish under 5 cm, or 5 medium fish from 5 to 10 cm, or 5 medium and large fish from 10 to 20 cm.

2.Goldfish eat grass, don't raise expensive ones.

3.The pump is enough, but the inlet should be low so that it can absorb garbage.

Fish farming should pay attention to: water quality should be fine, temperature and light should be appropriate, food quality and quantity, gentle operation, cautious medication, and stay away from toxic substances (pay attention to insecticides and mosquito coils at home).

1.Don't fish in multiple tanks Small There is a filter of 1 liter of water (length, width and height 10 10 10 cm) to raise 1 cm fish, and more will be very easy to get sick and die. The tank is at least 30 cm or more, it is easy to maintain the water quality, or there is no filtration equipment, please calculate the fish according to the water surface area, tropical fish need 30 square centimeters per centimeter of body length (excluding tail fin) water surface, goldfish need 60 square centimeters.

2.Open the tank to raise water should be disinfected with salt and then washed with water, add water, the water temperature in the tank should be between 28-30 degrees, water to be raised for 7 days, put in a few strong vitality of the fish for 30 days, (or after 3 days after entering the tank fish, add nitrifying bacteria every day for a total of 7 days, pay attention to avoid light) (or open the tank with "three bacteria", but pay attention to the appropriate amount, rather less, pay attention to avoid light and gas) (or immerse a peeled raw shrimp in the water in the filter tank during the water raising period until the shrimp is completely melted), there is filtration during the opening of the tank can not be stopped, 20 days, preferably more than 30 days after no incident, before officially releasing the fish. Also, don't let direct sunlight shine on the fish tank!
