Daily management of silver arowana

The breeding and management of silver arowana is a highly technical and complex job, which includes feeding, water changes, cleaning, daily observation, disease prevention and treatment, etc., and the daily management methods are different at different stages and seasons of silver arowana growth. When a small silver arowana is just bought, 1/3 of the water should be taken from the original tank and brought back to the new tank, and then new water of the same temperature should be added, and the water temperature should be controlled at around 28℃. The air pump should be running all day to completely eliminate the chlorine in the new water.

The strong water flow generated by the air pump can increase the amount of dissolved oxygen in the water, prompting the silver dragon to swim continuously, maintain its body shape, and prevent the silver dragon from turning over its gills. In addition, during the normal breeding process, a small amount of salt should be added to the aquarium to prevent fungal infection.

When arranging an aquarium for raising silver dragons, a water circulation filter pump should also be installed. Because there will be a lot of leftover bait and feces at the bottom of the aquarium every day. If not handled in time, these metabolites will rot and damage the water quality. Change the water once a week, half of the water each time, and keep the temperature of the new and old water balanced. The temperature difference should be controlled at 1-2℃. Be careful when changing the water to prevent the silver dragon from being startled and hurting its body.

Silver Arowana is a carnivorous fish. When the young fish first start to eat raw bait, you can feed them with freshly molted white mealworms, shrimp balls with their heads and tails removed and their shells peeled, bloodworms and other nutritious, easy-to-digest baits that Silver Arowana likes. Feed them 4 times a day, a small amount each time. When the young fish grow up, you can feed them with normal mealworms, shrimp balls with their heads and tails removed and their shells peeled, and small fish.

Feed 6 times a day, with a slightly larger amount each time. When the silver dragon grows up, you can feed it with larger fish, shrimp, loach, centipede, spider, grasshopper, cockroach and other live baits, but make sure these baits are free of infectious diseases or parasites. Artificial baits are best to use beef and beef heart with less fat content, or you can buy ready-made silver dragon special baits.

Silver Dragon's special bait contains protein, fat, carbohydrates, vitamins, minerals and trace elements, etc. Moreover, the bait can float on the water surface for a long time without dissolving and affecting the water quality.

Common diseases of silver arowana

Silver Arowana is a strong and easy-to-survive species of fish, but it can also become sick if the water quality is poor for a long time, or if it is infected by bacteria, fungi, parasites, etc. When a silver arowana becomes sick, the water should be changed first to reduce the number of pathogens, and then medicine should be added to restore the silver arowana's resistance.

When feeding small fish, shrimps and other aquatic products, if the food is contaminated and the silver dragon is weak at this time, it is easy to get sagittalis. This disease can be treated with salt bath: add 8kg of salt to 1 ton of water, and raise the water temperature to about 33℃. Replace 1/3 of the water every day and add salt according to the proportion. Repeat this cycle for 2 weeks, and the sagittalis can be removed.

In addition, you can anesthetize the silver dragon and remove the arrow worms directly by hand. However, you need to apply some salt after removal and raise the temperature to above 31°C to avoid bacterial infection.

When the water quality is not good, the silver dragon will lose its appetite, and sometimes its whiskers will stick together. At this time, you can change the water to improve the water quality to increase its appetite. For silver dragons raised at home, the most common disease is enteritis. This disease often occurs in spring and summer, mainly due to unclean water or feeding rotten bait. This disease is caused by intestinal Aeromonas punctata, so it is called bacterial enteritis.

The normal color of silver dragon's feces is black or gray-brown, long strips; if the color is milky white, it means that the silver dragon has indigestion and may suffer from enteritis. When silver dragon suffers from enteritis, the sick fish will start to be dull and slow in movement, lose appetite or even lose appetite. If not treated in time, it will die soon.

When treating, add 2-4g of furazolidinone or furazolidinone to 100kg, and soak the sick fish for about 30 minutes, twice a day. You can also mix enteritis-resistant or furazolidinone into artificial bait and feed it to sick fish, twice a day, for 7 consecutive days. Antibiotics can be used for prevention at ordinary times, with a dosage of 4 pills per 100kg, and change the water after immersion for 3 days.

Home breeding method of silver arowana 2 1. Preparation of seedlings.

In low temperatures, doors and windows should be closed, and the temperature in the fish room should be adjusted to 28°C. Choose a good fish tank. Generally, a fish tank with a diameter of 126 cm and a depth of 48 cm can hold 300 fry. Install filter cotton, activated carbon, coral stone, air pump and water pump, control the water depth of the tank to 20 cm, and adjust the temperature to 28°C. At the same time, prepare an appropriate amount of new water with a temperature of 25°C, 1% salt and 2 mg/kg furacilin.

2. Put the seedlings into the tank.

Quickly transport the fry back to the farm. After the fry arrive, immediately add an appropriate amount of spare new water to disinfect and sterilize them. Remove the dead and injured fish, re-oxygenate and pack them. After observing for half an hour, put the fish package into the fish tank to adjust the temperature. Only after 1 hour can the fish package be opened to put the fry into the tank.

3. Feed the fish to train them to eat.

The newly introduced silver dragon fish fry has a small yolk sac in its body, which mainly feeds on yolk. The yolk sac disappears after 7 days, and it is necessary to start feeding from the second day to meet its nutritional needs. Live bloodworms can be used for feeding (soak them in a 3% salt and 5g/L furazolidone aqueous solution for 15 minutes before feeding). Be very careful when operating, and feed them a quantity that can be eaten within 20 minutes.

4. Change materials at appropriate time.

Small silver arowana fry are mainly fed with live bloodworms within 10 days of age, and can be fed with quick-frozen bloodworms after 10 days of age. In the third month, they can be gradually transitioned to shrimps (both seawater and freshwater shrimps are acceptable, after removing the head and tail, cut into appropriate sizes, and rinsed with salt water before feeding).

Feeding time and frequency: Feed 5 times a day from 5 am to 10 pm in the first month, 4 times in the second month, 3 times in the third month, and 2 times in the fourth month. Note that 20 minutes after each feeding, remove the remaining bait.

5. Adjust the density.

Silver Arowana grows very fast. When it is first grown, its body length is about 6-7 cm. It can grow to 12 cm at one month old, 17 cm at two months old, and 24 cm at three months old. Therefore, during its growth, the stocking density must be adjusted in time according to the growth situation. It is best to screen it once every month. The first time is to stock 150 per tank, the second time is 70 per tank, and the third time is 25 per tank. The stocking number will be gradually reduced later, or it can be moved into a large tank for breeding.

6. Water management.

The suitable water level in the silver arowana fish tank is: 20 cm for 1 month old, 25 cm for 2 months old, 30 cm for 3 months old, and 35-40 cm for the rest. Depending on the water quality, the sewage should be sucked out once every 3-5 days in the first month (to remove the dirt at the bottom of the tank), and once a day from the second month onwards, and the water level should not exceed 5 cm each time.

Clean the filter cotton and activated carbon every 5 to 7 days. During the entire breeding process, the water pH, dissolved oxygen, temperature, etc. must be strictly controlled. The pH value is 6.8 to 7.2, the dissolved oxygen is 7 mg/L, and the temperature is 28°C. Once adverse changes in the water are found, appropriate measures should be taken immediately to adjust.
