CATDOLL : CATDOLL: Which fish grows the fastest?

1. Which fish grows the fastest?

Dwarf goby: It is not only the fastest growing fish in the world, but also the shortest-lived vertebrate discovered by science.

2. Why does hair fall occur? How to treat it?

Hello, I am a student of Chinese medicine. We Chinese medicine practitioners believe that hair is related to the qi and blood of two meridians in the human body, namely kidney qi and liver blood. Because the kidney is responsible for astringency, if the kidney is deficient, the kidney essence is not strong enough to store it, and hair loss is easy. The growth rate of hair is related to liver blood. Because the liver is responsible for hair growth, if the liver blood is insufficient, the hair will turn white and dry, and eventually lead to hair loss. The treatment must first regulate the liver and kidneys, and Qiju Dihuang Pills can be used. For external use, wash 90 grams of mulberry bark, cut it into small pieces, soak it in a casserole with water for 30 minutes, then boil it for five or six times, remove the residue, and use the liquid to wash your hair every night. It is suitable for hair loss and excessive dandruff.

3. How to increase the growth rate of fish?

How to increase the growth rate of fish? Rujin bacteria is an active compound bacterial agent composed of photosynthetic bacteria, lactic acid bacteria, yeast and other microorganisms. It is widely used in the aquaculture industry with remarkable results. In the process of fish farming, only by improving the quality of fish bait can the economic benefits be improved. The following are four ways to increase the growth rate of fish:

1. Adding vitamin C: When raising carp, add 700 mg of vitamin C per kg of feed, and when raising eel, add 500 mg of vitamin C per kg of feed. The weight gain effect is very significant. Adding 60 grams of vitamin C per kg of catfish feed can increase the daily weight gain of catfish by 50% and save 29% of feed. Vitamin E: Adding vitamin E to fish feed so that the vitamin E content per kg of feed reaches 40 mg to 70 mg can increase the daily weight gain of fish by more than 10%.

2. Adding mugwort: Mugwort is a widely distributed plant that contains protein, fat, vitamins, and various essential amino acids, minerals, etc. According to experiments, adding 5% mugwort to feed can increase the weight gain rate of one-year-old carp in pond feed by 15.4% to 22.4%, and the growth rate of silver carp and bighead carp raised in the same pond is also significantly improved. The weight gain rate of one-year-old carp raised in cages can be increased by 14.5%.

3. Add earthworms: earthworms contain 50.4% to 65.8% crude protein, a full range of amino acids, especially limiting amino acids, and are rich in vitamins. Because earthworm meat has a special smell, it is easy to lure and stimulate the appetite of fish. Adding 5% earthworms to compound feed can significantly reduce the feed coefficient of tilapia and increase economic benefits by 74.5%. Adding 7.14% to 10% dried earthworms to compound feeding can increase the growth rate of carp by 63%.

4. Add photosynthetic bacteria: Photosynthetic bacteria are used as bait additives for fish, shrimp, river crabs, and shellfish, and the survival rate is increased by 45% to 70%. When used in freshwater fish seedling cultivation, the survival rate is increased by 6.53%, the growth rate is increased by 15.2%, the weight gain rate is increased by 25.2%, and the feed coefficient is reduced by 25.96%. When used in eel farming, the weight gain rate is increased by 10%, and the disease resistance is improved.

The usage is:

① Feed addition. When photosynthetic bacteria are used as feed additives, the photosynthetic bacteria solution that has been expanded can be sprayed on the feed and mixed evenly. The amount of bacterial solution used is 1% of the amount of feed, and it should be prepared and used immediately.

② Water spraying. Water spraying is suitable for improving water quality, preventing and treating fish diseases, and cultivating excellent algae. Choose a sunny morning or afternoon, dilute the photosynthetic bacteria that have been propagated with pool water, and evenly spray the entire pool. Use 5 to 10 ml of photosynthetic bacteria solution per cubic meter of water, and each ml of solution should contain 1 to 1.5 billion photosynthetic bacteria. The number of times photosynthetic bacteria are applied depends on the water quality. If the water quality is good, it can be applied once every 15 days; if the water quality is relatively fertile or poor, especially in high-yield pools in the later stages of breeding, it should be applied once every 7 to 10 days. The propagated photosynthetic bacteria should be used as soon as possible, and should not be stored at room temperature for more than 2 weeks, and metal containers are prohibited for storage.

By adding vitamin C, wormwood, earthworms, photosynthetic bacteria, etc., the palatability of fish bait can be improved, the production cost of fish can be reduced, and the purpose of improving economic benefits can be achieved.

4. Do sea bass live in rivers or seas? Can they be farmed?

There are many varieties of perch, some of which live in rivers and some in the sea. Some perch belong to sea perch, and they live in coastal areas, mostly in shallow water. They also have the property of migration, sometimes they move to the estuary, and sometimes they directly enter freshwater rivers, and they have good adaptability to salt water and fresh water. There are also some perch that live in fresh water, which can be found in Europe and Asia. There are also some in my country, where they live in rivers. 1. Does perch live in rivers or in the sea? Perch is a relatively famous fish in my country, and it is relatively common in daily life. From a global perspective, there are many varieties of perch, and they are widely distributed. There are many varieties of perch living in my country alone. Although these varieties belong to the same perch and have some common characteristics, they are not all exactly the same, and their living environments may be very different.

Some of these species live by the sea and are sea bass. This type of sea bass generally lives in offshore areas, where the water depth is relatively shallow. They have migratory properties and sometimes move to river mouths, and sometimes even directly to fresh water. Therefore, this part of sea bass has a good adaptability to salt water, fresh water, and brackish water. There are also some sea bass that can only live in fresh water and are freshwater sea bass. They are distributed in Europe and Asia, and also in my country. These sea bass live in rivers.

2. Can sea bass be farmed? Sea bass are quite common in my country and can be farmed artificially. In real life, it is also quite common to farm them. They have high nutritional value and can be eaten, so they also have certain economic value, and many breeders choose to farm them. Due to the large number of breeding, breeding ponds are generally used for breeding. When breeding them, breeders will use freshwater or seawater breeding methods according to their species. When breeding, if you want the sea bass to grow fast, there are still many issues that need to be paid attention to, such as water depth, water temperature, water quality and food.

5. What should you pay attention to during the first three months of pregnancy? What should you not eat?

In the first three months of pregnancy, you need these foods: The first month: Because you often don't know you are pregnant, you fail to include three meals a day in the special track of pregnancy, which is very unfavorable for eugenics. In fact, nutritional preparation should start from two months in advance, and should be strengthened after the pregnancy is confirmed. Eat more high-quality protein foods rich in essential amino acids, such as milk, fish, lean meat, eggs, beans, etc. At the same time, pay attention to the intake of folic acid, which is a B vitamin and has made outstanding contributions in preventing fetal neural tube defects. It is mainly distributed in green leafy vegetables, animal liver and kidney, and various fruits, so pregnant women should also eat more of these types of food. The second month: There are more early pregnancy reactions, irritable temperament, and poor appetite. Therefore, it is advisable to eat more foods that can stimulate the appetite and strengthen the spleen, such as apples, loquats, pomegranates, rice soup, white beans, red beans, duck eggs, sea bass, white radish, cabbage, winter melon, yam, red dates, etc. In addition, increase foods rich in fiber, such as fresh vegetables, to prevent constipation. The third month: Because the fetus develops rapidly, it needs to supplement high-quality protein, calcium, zinc, and plant fat, so you should eat more foods rich in the above ingredients, such as oysters, jellyfish, soybeans, milk, etc. In addition, you should eat more foods rich in vitamin E, such as vegetable oils, malt, etc. As for those that cannot be eaten, there should be nothing wrong with the food, but the key is to try not to use drugs, just pay attention to this. Drugs, whether Western medicine or Chinese herbal medicine, have more or less adverse effects on the fetus. A German medical expert said: "It is best not to use any medicine during pregnancy, with only two exceptions, one is iron and the other is calcium." But it is very difficult to do this, because a 10-month pregnancy is not a short time, and it is not easy to avoid any disease for 10 months. However, at least try to ensure that no drugs are used in the early pregnancy, which is only 3 months, and you should try to do it. Because the first 3 months of pregnancy is a critical period for the differentiation of various organs of the embryo, it is particularly sensitive to the teratogenic factors of drugs and is most likely to cause teratogenesis. For example, the teratogenic susceptibility period of the central nervous system is 15 to 25 days after pregnancy, the heart is 20 to 40 days, the eyes are 24 to 39 days, the limbs are 24 to 46 days, and the external genitalia are 36 to 56 days. After three months of pregnancy, the fetal organs have been formed, and the teratogenic effects of the external environment are greatly reduced. Not only does the vomiting reaction decrease, but the safety of medication is also increased. Of course, for safety reasons, you still have to listen to the doctor when you are sick, take medication under the doctor's guidance, and try to minimize the adverse effects of medication on pregnancy.
