CATDOLL : CATDOLL: How to cherish pet animals

1. How to cherish pet animals

1. Feeding: All feeds are nutritious animal feed and white sesame. Animal feeds include water fleas, earthworms, mealworms, caterpillars, and skinworms. The main feeds are earthworms and white sesame. Both red and black earthworms can be fed. Raw white sesame can be fed as the main food. White sesame is easy to buy. Goldfish love to eat it, it is easy to digest, and it is not easy to pollute the water quality. Do not feed the inferior goldfish feed you buy. Because this kind of feed has too much starch, poor nutrition, difficult to digest, and easy to pollute the water quality. Goldfish will be malnourished after eating it, and the growth of goldfish will be slower and they are prone to diseases. As long as goldfish eat easily digestible food, they will not die of bloating. When to feed? Generally, once in the morning and afternoon every day. It is not advisable to feed more, and feed until all the food is eaten. Otherwise, it will pollute the water quality.

2. Light: It is best to place the fish tank in a place where there is sunlight for 1-2 hours. In this way, the ultraviolet rays of the sun can be used to sterilize. It plays a role in disease prevention. This can reduce diseases. Try to prevent fish diseases as the main method and use medicine as the auxiliary method. At the same time, due to photosynthesis, the color of the fish body is also brighter and more beautiful.

3. Change water: Change water frequently to increase dissolved oxygen in the water. When changing water, only one-third to one-quarter of the water should be changed. Do not change a lot at once, or the fish will not adapt. It is very important to keep the water in the aquarium clear. Fish can only grow and grow fast if there is sufficient dissolved oxygen in the water. Otherwise, they will stop growing or even die. There is no definite answer to when to change water. It can be determined according to the water quality. Change water more often if the water is turbid, otherwise change less often.

4. Stocking density: Because the rectangular aquarium for domestic use is small in size, it is not advisable to raise too many fish. It is better to raise less rather than more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 to 8 small goldfish of 5 to 7 cm in length can be raised. For example, in a round glass tank with a diameter of 26 cm and a height of 13 cm, 4 to 6 small goldfish of 4 to 6 cm in length can be raised. Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but should be raised in a large glass tank or a ceramic tank, and equipped with a small oxygenator to prevent hypoxia. These stocking densities are only reference numbers, and they should be determined by the water temperature, the strength of the fish, and the quality of the water. They cannot be mechanical. Generally speaking, the larger the fish, the fewer the number of fish to be raised; raise more in winter and less in summer; raise more when the water temperature is low and raise less when the water temperature is high. If you master the above points when raising goldfish at home, you will be able to keep them healthy and lively, colorful, swimming in the water, and being loved by people, so that you will never get tired of watching them and have endless fun. You will definitely be able to raise them well, and I wish you success.

Tips for raising goldfish: 1. Feeding: Feed them with nutritious animal feed and white sesame. Animal feed includes water fleas, earthworms, mealworms, caterpillars, and skinworms. The main feed is earthworms and sesame. Feed both red and black earthworms. Do not feed them with purchased inferior goldfish feed. Because this feed has too much starch, poor nutrition, and is difficult to digest, it is easy to pollute the water quality. Goldfish will be malnourished after eating it, and the growth of goldfish will be relatively slow, and they are also prone to disease. 2. Lighting: It is best to put the fish tank in a place where there is sunlight for 1-2 hours. In this way, the ultraviolet rays of the sun are used to sterilize. It plays a role in disease prevention. This can reduce diseases. Try to prevent fish diseases as the main method, and use medicine as a supplement. At the same time, due to photosynthesis, the color of the fish body is also bright and beautiful. 3. Change water: Change water frequently to increase the dissolved oxygen in the water. When changing water, only one-third to one-quarter can be replaced. Do not replace a lot at once, otherwise the fish will not adapt. It is very important to keep the water quality in the aquarium clear. Fish can only grow fast if there is enough dissolved oxygen in the water. Otherwise, they will stop growing or even die. 4.

Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but should be raised in a luxurious large glass tank or a ceramic tank, and equipped with a small oxygenator to prevent hypoxia. These stocking densities are only reference numbers. They should also be determined by the water temperature, the strength of the fish, and the quality of the water. They cannot be mechanical. Generally speaking, the larger the fish, the fewer the number of fish; raise more in winter and less in summer; raise more when the water temperature is low and raise less when the water temperature is high.

3. How to keep goldfish safe during the winter?

Goldfish are weak and delicate. How to safely overwinter in the harsh conditions of very low temperatures is related to the breeding and reproduction of goldfish in the next year. Therefore, the wintering management of goldfish is very important. The wintering management methods are briefly described as follows.

1. Wintering in the pond

As the temperature drops, the remaining goldfish sold in autumn and the goldfish kept as broodstock will begin to hibernate and enter the winter management stage. In winter, the water temperature is low, the fish have little activity, and consume less oxygen. For the convenience of management, goldfish are usually concentrated in deep pools or indoor greenhouses to hibernate. The time for pooling is earlier in the north, usually around the time of frost; and later in the south, usually between the heavy snow and the winter solstice.

Before wintering in the same pond, first of all, we need to strengthen autumn cultivation and provide more live Daphnia to promote their growth and development, accumulate protein and fat in their bodies, and prepare for wintering. At the same time, it is beneficial to the development of the gonads of the broodstock. The daily feeding time can be appropriately extended from 7 to 8 am to 2 pm.

Secondly, before wintering, new water should be added, because there will be a lot of goldfish feces and dirt deposited in the pond, and the water quality is "old water". In addition, a layer of ice forms on the surface of the water in the north in winter, which isolates the water from the air, which can easily cause the goldfish to die of suffocation due to lack of oxygen. When adding water, the water depth should be increased to about 80 cm. The surface layer is frozen, and the water temperature in the middle and lower layers is still maintained at about 4°C. Goldfish are basically in a dormant state and rarely move, so there is generally no big problem. In clear and windless weather, chisel the surface ice on the south side and pick it up to allow the water to contact with the air and replenish the dissolved oxygen in the water, so as not to suffer from lack of oxygen. After snowing, clear the snow on the ice layer to avoid insufficient photosynthesis of plankton and cause lack of oxygen in the water.

Finally, it is important to stock the fish at the right time. The water temperature should be between 5℃ and 10℃. If the fish are combined too early, the water temperature is too high, and the density of the fish is high during the winter, it is easy to make the water turbid and cause hypoxia. If the fish are combined too late, the fish will often get frozen and become sick. Generally, the time for wintering should be before ice forms. The stocking density can be higher. Calculated per square meter, 12 to 15 large goldfish with a body length of 15 to 20 cm can be stocked; 45 to 60 goldfish with a body length of 10 to 15 cm can be stocked; 75 to 100 goldfish of the same year with a body length of 5 to 10 cm can be stocked. When combining the fish, the fish should be fished gently. The water temperature is low at this time. Once the goldfish is injured, it is difficult to recover. During the winter, it is easy to be infected with bacteria and become sick, such as swim bladder disorder and pine scale disease.

2. Wintering outdoors

Goldfish can also overwinter outdoors. As long as they are properly managed, the survival rate can be above 90%. For outdoor overwintering, you must choose a deep pool, generally with a water depth of more than 2 meters, such as a reservoir, earthen pond, etc. In the specific operation, you should pay attention to the following aspects:

1. Pond cleaning and disinfection

The pond must be cleaned in advance, the silt at the bottom of the pond must be dug out, and quicklime water must be sprayed to kill harmful organisms. After the toxicity disappears, new water must be injected and the fish can be released into the pond.

2. Reasonable stocking

The stocking time should be selected when the water temperature is about 5℃, preferably at noon on a sunny day. The fish to be stocked must be healthy and healthy. The stocking density should not be too large. Wintering goldfish live under ice, and the gas in the water cannot be exchanged with the outside world. Generally, only 5 to 8 fish can be stocked per square meter.

3. Strengthen management

On sunny days, you should be diligent in clearing snow and ice to increase dissolved oxygen in the water, and at the same time prevent human damage. Goldfish that overwinter outdoors are more resistant to disease than those that overwinter indoors, and can better withstand the large temperature changes in the spring of the following year.

3. Wintering indoors

When the water temperature is around 10℃, move the goldfish into an indoor pool for wintering. The fish pond should first be filled with new water, and the stocking density should be 2 to 3 times higher than the outdoor stocking density in autumn. The water temperature can be kept at 2℃ to 10℃ throughout the winter. When the water temperature is high, you can feed a small amount of goldfish, use a straw to suck out the dirt at the bottom of the pool every few days, and then slowly inject an appropriate amount of new water, and the temperature difference should not exceed 2℃. The characteristic of indoor wintering is that the survival rate of goldfish is high, generally reaching more than 95%.

4. Wintering in a greenhouse

A good fish pond has a glass or plastic greenhouse for goldfish to overwinter. The greenhouse can receive sunlight well and has good heat preservation effect. When the outside water temperature drops to 15℃, the water temperature in the greenhouse can reach 25℃. Goldfish can eat and grow normally after entering the greenhouse. The following aspects should be paid attention to when overwintering in the greenhouse:

1. Prepare a warm house

The goldfish room should be located in the north and face the south, with shelter from the wind and facing the sun, and be transparent and heat-insulating. There should be heating equipment in the room, and convenient water and electricity supply. Prepare straw or cotton curtains that can be opened freely, so that they can be covered at night and opened in the morning, playing the role of keeping out the wind and cold at night and letting in light and heating during the day.

2. Feed appropriately

Under the condition of suitable water temperature in the greenhouse, you can feed more and change water frequently. When the severe winter comes and the water temperature drops below 16℃, you should feed less and change water less frequently. In the early spring of the second year, when the water temperature rises above 16℃ again, the goldfish in the greenhouse will go into heat and lay eggs, which is 20 to 30 days earlier than the normal spawning time. You can manage the goldfish as breeding fish to make them lay eggs in advance, or you can move the goldfish outdoors for breeding. The characteristic of wintering in a greenhouse is that it shortens the wintering period of goldfish. Goldfish can still eat and grow in the greenhouse and can reproduce in advance.

3. Strengthen management

Mainly, keep warm and feed the fish appropriately, and try to keep the fish from becoming too thin and sick. Throughout the winter, water changes, water additions, and cleaning operations should be reduced to a minimum while ensuring the safety of the goldfish. Change the water once a month and clean the fish every 3 to 5 days. When operating, fish less and touch less to prevent the fish from being damaged, bleeding, or losing scales, so as to prevent the spread of Saprolegniasis and White Spot Disease (goldfish with these diseases are difficult to treat) to avoid causing greater losses.
