CATDOLL : CATDOLL: What are the four major benefits of wide water fish farming technology for raising ornamental fish?

1. What are the four major benefits of wide water fish farming technology for raising ornamental fish?

1. Ornamental fish grow fast!

Under normal circumstances, the larger the water body, the faster the fish grow. Why are all the fish in the wild so strong and big? One of the reasons is that the environment is very large, the space for activities is very large, and the growth is relatively fast. Fish can swim freely in large water bodies without being confined to a small space and suffocating. They can have sufficient physiological swimming every day, which is more conducive to fish digestion of food, absorption of nutrients and growth.

2. The water quality can remain relatively clean for a long time.

When fish are raised in wide water, the feces, organic matter, impurities and other wastes produced by the fish will accumulate in the fish tank. However, in the case of a large water body, these impurities will not have a significant impact on the ornamental fish. The content of harmful substances is low and will not cause any harm to the fish. In the case of a large water body, the water quality will not deteriorate without changing the water for a long time, and the larger the water body, the more controllable the water quality. Compared with small tanks, most dead fish are due to water deterioration or water quality problems, but this rarely happens in wide water fish farming. Because the water body is large and there are few fish, the harmful substances produced can be almost ignored, and the water can basically be changed once every half a month or more.

3. Good viewing effect.

In large water bodies, fish have more room to display their talents. The original social unit of fish is actually the "fish school". Many fish socialize with each other, so they will form a fish school. And there is one group for each type of fish. When they form a social relationship to form a fish school and swim in groups, this is called "school swimming". And the fish swimming in groups are very spectacular. Large water bodies will make fish feel less secure, so they will gather into a fish school to gain a sense of security. In addition, if the water body is larger, the school swimming effect is very good, much better than in a small tank. In the case of a large water body, you can not only see the fish swimming in groups, but also see more postures and beauty of the fish.

4. Choose more.

A wide water tank can be used to raise more fish species, whether large or small, cold water or tropical, adult or juvenile. In a large tank, as long as the environment is well arranged, almost any fish can be raised.

Wide water is actually used for fish farming. Small tanks can only be used for practice. The first step in fish farming must be to use a small tank, which is easier to deal with. Build various filtration systems, bacterial populations, etc. on this small tank, and constantly test and practice to lay a more solid foundation. When you have a more solid foundation, you can start the real road of fish farming and raise fish with large water. Small tanks can only raise small fish, and you can't raise too many, which will bring a lot of burden to the bacteria and easily kill the fish. Fish in a small environment are more likely to fight, and it is not easy to maintain good water quality.

Abundant water is the ultimate destination for raising ornamental fish.

First, ornamental fish grow faster, second, the water is cleaner, third, the ornamental effect will be better, and fourth, there will be more fish species to choose from.

This is more conducive to the growth of ornamental fish, making the fish more lively and cute, and more resistant to disease.

1. Make ornamental fish grow faster

2. The water quality can remain clean for a long time

3. Better viewing effect

4. More species can be raised

2. Which is better, white mullet or black mullet?

First of all, white mullet and black fish are both members of the Channa genus of the Channidae family (Channa ulmoides, Channa scutellaria, Channa ulmoides, Channa ulmoides, Channa ulmoides, and white Channa ulmoides). The breeding costs and production methods are the same. Compared with black mullet, white mullet:

1. The color of white mullet is much more beautiful than that of black fish, especially the special white mullet, whose fins (chest, tail, and pelvic fins) are golden yellow, which looks very beautiful. It can not only be eaten, but also sold in the ornamental fish market.

2. The nutritional value of white mullet is higher, which is reflected in high protein, high trace elements, high amino acids and low fat.

3. White mullet is very, very rare (scarcity makes things valuable). Compared with black mullet, white mullet can completely replace black fish (the consumption of black fish in our country is second only to the four major carps in terms of freshwater fish). White mullet is also called white-armored black fish (Opniocepnalus argus var Kimnra), commonly known as white black fish, Channa genus of Channa family. The meat is tender, with few bones and delicious taste. White mullet medicinal food can promote lactation, promote muscle growth and activate blood circulation. It is a nourishing treasure for postpartum women and the elderly and children. It is rich in nutrition and can be used to make a variety of famous dishes, such as stir-fried fish fillets, white chrysanthemum fish shreds, white black fish stick stewed with snake, etc. So relatively speaking, white mullet is better.

White mullet is better than black mullet. The nutritional value of white mullet is higher than that of black mullet, which is reflected in high protein, high trace elements, high amino acids and low fat. Moreover, white mullet is very rare, and compared with traditional black mullet, the price of white mullet is relatively high.

3. What fish can be raised together with goldfish?

Goldfish are not suitable for being raised together with tropical fish. The breeding environment of tropical fish requires an environment above 20 degrees, while goldfish can be kept at the same temperature as the environment.

Regarding the pH of water, goldfish prefer to live in soft water with a slight acidity, while tropical fish prefer to live in neutral to alkaline water.

Planting water plants in tropical fish tanks can increase the ornamental value and make it more suitable for tropical fish. Keeping goldfish in a tank with a lot of water plants will make it difficult for them to swim and find food.

Additional information:

When feeding goldfish, try not to feed them greasy baits. Oil will block the surface of the fish tank, resulting in insufficient dissolved oxygen in the water, which may cause the goldfish to suffocate and die. If you feed them live food such as mealworms, be sure to ensure that the live food does not carry bacteria, otherwise it will easily make the goldfish sick. Do not feed them in large quantities to prevent excess bait from polluting the water quality. Feed them once or twice a day, and the amount of bait each time should be enough for the goldfish to finish eating in about 10 minutes. Do not feed a single bait for a long time. Mix the baits to ensure that the nutrition is comprehensive and sufficient.

Goldfish can be kept together with goldfish of the same species, but not with fish of different species.

Goldfish are not suitable for mixed breeding with tropical fish for the following reasons:

1. The habits and maintenance conditions of the two types of fish are different. Tropical fish need to be kept in water above 20 degrees, while goldfish can survive the winter at ambient temperature (i.e. without heating); if they are kept together, the water occupied by the goldfish will also be heated, which will increase the electricity bill;

2. Tropical fish are agile and have strong foraging ability, while goldfish are slow and have weak foraging ability. In addition, tropical fish have a small appetite while goldfish have a large appetite. If they are kept together, goldfish will not get enough food and will suffer from malnutrition.

3. Some tropical fish will chase and bite the fish's tail. Goldfish swim slowly, so they are bound to be bitten. Planting water plants in tropical fish tanks can increase the ornamental value and is more suitable for the life of tropical fish. Keeping goldfish in a tank with a lot of water plants will make it difficult for them to swim and forage.

4. Tropical fish consume less oxygen when breathing, while goldfish consume more oxygen. Mixing them together can easily cause goldfish to die early due to lack of oxygen. It seems uncoordinated to keep the two types of fish together, and it will feel weird.

Goldfish and tropical fish water temperature requirements

Goldfish are cold-blooded animals with strong adaptability to water temperature. Their body temperature changes with the water temperature and they can survive in water temperatures between 0 and 39 degrees Celsius. However, goldfish cannot adapt to drastic changes in water temperature. A sharp rise or fall in temperature of more than 5 degrees Celsius may endanger the life of the goldfish.

The optimum temperature for goldfish's growth is 20-28 degrees Celsius. At this water temperature, goldfish grow and develop most vigorously, and their food intake, excretion and oxygen consumption are the largest. At this time, goldfish are the most colorful and lively.

The water temperature for tropical fish is generally between 20 and 30 degrees Celsius. However, different species of tropical fish have different requirements for water temperature. For example, guppies, red swordfish, black mollies and other fish can tolerate water temperatures of around 10 degrees Celsius without dying, while angelfish, tiger barbs and other fish will die when the water temperature is below 18 degrees Celsius.

Most tropical fish are extremely sensitive to water temperature. They will catch a cold if the water temperature changes by ±2℃. If the water temperature fluctuates up and down for a long time, the fish will suffer from various diseases. Therefore, try to keep the water temperature constant.

The water temperature should not be too high. If the water temperature is too high, the fungi in the water will multiply too fast and affect the water quality. The normal temperature for most fish is 20-24℃, and the breeding water temperature is 25-28℃. There are two common ways to control water temperature, which are natural control and artificial control.

Generally, it is best to keep each species separately. If you want to keep them together, you should mix them with the same species. However, the head-nodular and pearl fish in the Wen species can be mixed with the egg-type fish, and the goldfish in the Wen species can barely be mixed with the grass goldfish and koi, but it is best not to have too big a difference in size. If you want to keep them together, make sure the habits of the fish are similar.

It is not recommended to raise goldfish and tropical fish together, as the two types of fish have different habits and breeding conditions.

1. Tropical fish should be kept in water above 20 degrees, while goldfish can survive the winter at ambient temperature (i.e. without heating).

2. Tropical fish are agile and have strong foraging ability, while goldfish are slow and have weak foraging ability. In addition, tropical fish have a small appetite while goldfish have a large appetite. If they are kept together, goldfish will not get enough food and will suffer from malnutrition.

3. Some tropical fish will chase and bite the fish's tail. Goldfish swim slowly, so they are bound to be bitten.

Additional information:

Polyculture refers to the technical measure of raising several types of fish in a certain proportion in the same water body.

Fish species that are mixed-breeding must have different habitats and feeding habits, and they must not cannibalize each other. For example, silver carp and bighead carp are pelagic fish, and their main food is plankton; grass carp, bighead bream, and bream are pelagic fish, and their main food is grass; black carp, carp, crucian carp, dace carp, and silver carp are bottom-dwelling or bottom-dwelling fish, black carp eats snails, clams, etc., carp and crucian carp eat bottom-dwelling animals and some organic debris, dace carp and silver carp eat organic debris and epiphytic algae.

They cannot be raised together. Goldfish and tropical fish have different requirements for water quality. Goldfish prefer weakly alkaline water, while tropical fish prefer weakly acidic water. Goldfish are cold-water fish with a lot of mucus and high oxygen consumption. It is best not to raise them together with tropical fish.

Goldfish is an ornamental fish that Chinese people like to raise. It has a strange shape and bright colors. It can be said to be a natural living work of art, so it is loved by people.

Precautions for raising goldfish

1. Choose high-quality fish;

2. Choose a suitable container and pay attention to the density.

3. Choose fresh and loose bait to feed fish. Keep the water fresh and feed 1 to 2 times a day.

4. Clean stains promptly.

Can be raised together with goldfish of the same species.

Goldfish cannot be raised together with tropical fish, as the two types of fish have different habits and breeding conditions. Some tropical fish will chase and bite the fish's tail, and goldfish swim slowly, so it is inevitable that they will be bitten.

Moreover, goldfish can survive the winter at normal ambient temperatures, while tropical fish must be kept in water above 20 degrees.

Additional information:

You should choose goldfish species that are suitable for breeding in cages, such as lionhead, red top, pearl, Chaotian, Ryukyu, etc. Generally, it is better to only choose the same species of the same size in one cage.

Goldfish are more suitable for group breeding and intensive breeding. However, the density of domestic breeding should not be too large. The ideal water-fish ratio should reach 1000:1, and the length of the goldfish and the length of the fish tank should reach more than 1:10. This can ensure good water quality and sufficient dissolved oxygen.

Otherwise, excessive breeding density will cause the water quality to deteriorate rapidly and there will be insufficient dissolved oxygen in the water, and goldfish will easily die of disease and lack of oxygen.
