CATDOLL : CATDOLL: How to farm horsehair fish

1. How to breed horsehair fish

The scientific name of the horsehair fish is Channagachua, which belongs to the Channa genus of the Channidae family. It is commonly known as horsehair fish, white-edged Channa, bighead fish, black fish, and southern Channa. Environmental brightness: Since southern Channa is secluded during the day and active at night to hunt. Therefore, a dark environment is more suitable, so that they feel more secure, and their natural colors are more gorgeous. These are fish species that have been transferred to artificial breeding relative to wild species. If they are trained to adapt to the environment from a young age, it is another matter. Because of the obvious wildness and the habits have been formed, it takes a long time to domesticate! Of course, fish also have temperaments, and there are exceptions. They are easy to get along with and are not afraid of people. Therefore, I personally prefer those that are raised and trained from a young age! Water quality requirements: I like weak acidic water; of course, there is no problem with direct neutral water breeding. The key is how to use water, this is a dead rule. The water that has been dried and raised shall prevail. Acidic water can be treated with driftwood or black water (written in the instructions). In one, put lazy leaves! I used it only because there was a piece of driftwood inside, and the specific PH value was not measured! In fact, get an empty container, put some water in it and replace it directly when needed. I used a foam box. Change some water every day when you have time, even 1 cup is good. After all, there are plants in it. In a word, fish farming focuses on water! Temperature requirements: In fact, there are some to avoid, and they are kept indoors. As long as the temperature difference does not exceed 3 degrees in an instant, there is no problem. It is still very meaty. Because there is no excess, can be treated, and free time. So there is no specific experiment! However, maintaining a constant temperature is a blessing for you who love fish. Putting a heating rod to adjust to 24 degrees Celsius will definitely help you raise fish well. In normal southern weather, if you keep it indoors, there will never be a big change in temperature in an instant if you turn on the light. What needs special attention is actually changing the water. Slowly injecting new water is the key. The body length is less than 300mm. Likes to live in water bodies with muddy bottoms and many aquatic plants. Reclusive during the day and active at night. It feeds on small fish, shrimp, insect larvae, etc. It is distributed in the water systems of Yunnan, Guangxi, Guangdong, Hainan and Taiwan Province.

2. What do koi eat to grow big?

1. Adding mugwort and wormwood to food is a widely distributed plant that can be found in the wild in rural areas. Adding 5% of mugwort to koi fish feed can increase the weight of 1-year-old koi fish by 15%-22%, because mugwort contains fat, protein, vitamins, various amino acids, minerals, etc. Trace elements such as zinc, manganese, cobalt, and molybdenum in minerals can promote the growth of koi fish. However, excessive amounts are not suitable.

2. Add earthworms to the bait. Earthworms contain a large amount of protein, vitamins, and a full range of amino acids, especially restricted amino acids. Earthworms themselves have a unique smell, which can enhance the appetite of koi fish and greatly increase their appetite. Adding 7%-10% of dry earthworms to fish feed can increase the growth rate of koi fish by 63%.

3. Vitamin supplementation. Vitamins can promote the weight gain of koi fish. Adding 40-70 mg of vitamin C and E per kilogram of feed can make koi fish gain 10% weight every day.

Additional information

1. Raising koi can not only improve your mood and cultivate your character, beautify the environment, but also, as long as you have the right appreciation and breeding methods, the promising small and medium-sized koi purchased at a low price, after breeding, can win awards at the tasting meeting, and your status will be doubled. Not only can you enjoy the fun of raising and appreciating koi, but you can also maintain and increase the value. With the continuous improvement of koi quality and breeding technology, especially in the past two or three decades, many koi clubs have been established around the world to hold various koi tasting meetings, which has promoted the exchange and development of koi around the world, and the breeding trend is in the ascendant.

2. In Hong Kong and Guangdong, several koi tasting conferences are held every year. Koi also plays a big role in the cultural exchange of various countries. Emerging regions such as Malaysia, Singapore, and Israel have all started to raise koi on a large scale. Among them, Japan's propaganda method is the most powerful, and it once promoted it as a Japanese origin. You can refer to South Korea's registration of the Dragon Boat Festival, which is similar.

3. Ornamental koi really originated in China and flourished in Japan. Japan's marketing and variety promotion are worth learning from. The saying that good wine needs no bush should be interpreted differently in different eras. People generally call goldfish two categories - goldfish and grass goldfish. They are ornamental fish left over from the ancient Chinese court and can be raised in most areas of my country. There are quite a lot of branches of goldfish, and grass goldfish include koi and brocade crucian carp.

3. What are the signs of lack of oxygen in fish ponds? How to deal with it?

It is common in summer and autumn for farmed fish to float or overflow due to lack of oxygen in the pond water. The causes of this are not only due to poor management and poor pond water quality, but also directly related to bad weather.

There are three main types of adverse weather that cause fish to float to the surface and flood the pond. The first is precipitation weather: strong sunshine during the day, but a sudden thunderstorm around dusk, or cloudy and rainy weather with a lack of sunshine for several days; the second is hot and humid weather: long thunderstorms without rain, weak wind, hot and humid weather with low air pressure for several days, and cloudy weather after a long period of clear weather; the third is strong wind weather: clear and high temperature during the day, south wind, north wind at night, and rapid temperature drop, which is more common in autumn.

In order to prevent fish from floating to the surface and flooding the pond, in addition to carefully managing the pond water quality, production should also pay attention to watching (listening to) weather forecasts, grasping weather change information, and taking corresponding management measures for different types of adverse weather.

1. When bad weather occurs, nighttime pond inspections should be stepped up to identify problems in a timely manner and handle them promptly.

2. When bad weather occurs, the amount of feed should be appropriately reduced, and feed should be given in the morning as much as possible. Do not feed at night to avoid aggravating the degree of fish hypoxia and floating.

3. On sunny afternoons with thunderstorms or low-pressure, hot and humid days, the aerator should be turned on at noon to agitate the water and increase oxygen, thus reducing the oxygen consumption factor of the pool water at night.

4. If there are continuous rainy days and northwest wind suddenly blows at night, causing rapid temperature drop, and the fish in the pond are in serious danger of floating, the machine should be turned on to increase oxygen or flush with new water with high oxygen content around midnight before the fish float to the surface, and the machine should be turned on until the next day when the fish do not float to the surface.

5. For ponds without aerators and water sources, sufficient oxygenators should be prepared in advance. Once the fish in the pond float seriously, they should be used immediately to rescue them.

The solubility of a gas decreases with increasing temperature and decreases with decreasing pressure.

In hot summer and before a rainstorm, the temperature rises and the pressure decreases, which reduces the solubility of oxygen in water. The amount of oxygen dissolved in water also decreases, and fish are prone to death due to lack of oxygen. So it should be: in summer, the temperature rises, the content of O2 dissolved in water decreases, the air pressure decreases, and the solubility of O2 decreases.
