CATDOLL : CATDOLL: What kind of fish is good to keep in the pond?

1. What kind of fish is good to raise in the pond?

Raise economical fish. Silver carp and bighead carp are in the middle and upper layers of the water, while carp and grass carp are bottom fish. This combination does not waste food. Then you can raise some catfish, but remember to put other fish first. When the other fish grow up a little, put catfish fry. You can control it yourself. It can eat some miscellaneous fish, but it must be cleared out with other fish. Do not put fry in the middle. First raise some low-priced economic fish, slowly explore and gain experience, and then raise some fish with high economic value according to the local geographical environment and water quality.

Carp, crucian carp, silver carp and bighead carp are the most profitable to make a fishing pond near the city.

Roasted chicken with chestnuts! This is my favorite home-cooked dish in autumn. You will never get tired of it no matter how many times you eat it! Chestnuts will absorb the deliciousness of the chicken juice, and with their own glutinous taste, they will be sweet and soft when you eat them, and you can finish several bowls of rice with it. Wash 1000g chicken and cut it into small pieces. Put it in cold water and blanch it. Bring it to a boil over high heat and cook it for 2 minutes. Take out the chicken pieces and rinse them with cold water. Drain the water for later use. Put 600g of peeled chestnuts into hot water and boil for 10 minutes, then take them out and rinse them with cold water for later use. Heat the pan with cold oil and add ginger and garlic to the pan.

The eggplant is baked soft and tasty, and an egg is put in. It is baked into a runny shape and then mixed well. The taste is smooth and no one who has eaten it will say that they don’t like it. Just thinking about it makes me feel delicious. In order to let friends make it at home, I made a microwave version this time. Although eggplant is thick and juicy, it has a light taste, so seasoning is particularly important. First, stir-fry a quick garlic sauce, sauté the garlic, and add some soy sauce and oyster sauce to bring out the salty and fresh taste. Then add the three soul treasures of barbecue: cumin powder, chili powder and pepper powder. Only after adding these three powders can the taste of barbecue be in place, and it will be fragrant in minutes. Cook the whole eggplant, cut it into pieces, spread the seasoning, and add the egg. Juicy eggplant with spicy garlic sauce, and the eggplant is wrapped with moist and runny egg liquid.

Scrambled eggs with tomatoes! I know this is very conventional, but it is actually my boyfriend's favorite. But! As long as there is scrambled eggs with tomatoes on the table, it will always be the gold medal dish! Whoever compares with it will be the gold medal! No matter whether other dishes are Buddha Jumps Over the Wall or Roasted Whole Lamb, it is the first place as stable as Mount Tai. It makes me unwilling to make scrambled eggs with tomatoes easily in the future, because it will seem unfair to other dishes.

‍‍It must be the sweet and sour pork from my great Northeast! It can be said that this dish has been with me since I first ate it in a restaurant when I was three or four years old. Whenever I go to a restaurant to eat, the must-order dish is sweet and sour pork. And I have roughly ranked the restaurants I have eaten in our small county according to the level of making sweet and sour pork. If the sweet and sour pork is well made, then the other dishes will definitely not be bad.

‍‍My favorite is the mountain starch dumplings from my hometown in Anqing! My mother said that I didn’t like to eat when I was a child, but since I had teeth and could eat mountain starch dumplings! I have never lost weight! I don’t even want rice when I have mountain starch dumplings! I just pick up the bowl and eat! The opportunity I look forward to most every year is to go back to my mother’s country! The taste is the best! The sweet potatoes grown by ourselves and the pigs raised by ourselves! ‍‍

3. How to breed grouper and mandarin fish

How to keep freshwater grouper:

1. Biological characteristics

1. Morphological characteristics: The body of freshwater grouper is spindle-shaped, with an upper mouth and a body shape similar to that of mandarin fish. There are eight black stripes on each side of the trunk, and the body surface of adult fish is slightly yellow. The pectoral fins are light yellow, and the pelvic fins, dorsal fins, and anal fins all have black stripes. The black stripes on the caudal fin are perpendicular to the body. In addition to the black and white stripes, the body surface of adult fish is light yellow, and the body color changes with the external water environment. During reproduction, the male fish has a darker body color, while the female fish has a lighter body color with yellow. The pelvic fins are located on the chest, the caudal fin is round-tailed, and has a reproductive process. 2. Living habits: Freshwater grouper is a tropical fish that grows in fresh water and can also grow in seawater with a salinity of less than 10‰. Its suitable temperature range is 25℃~30℃. When the water temperature drops below 20℃, the food intake is significantly reduced. When the water temperature drops to 15℃, the body loses balance and begins to die. In winter, greenhouses should be used for warm breeding management. During the winter, the water temperature should be kept above 19°C to ensure the normal metabolism of grouper. Freshwater grouper is a bottom fish, resistant to hypoxia and strong in disease resistance. It can be mixed with tilapia and crucian carp to remove small fry in tilapia and crucian carp ponds, which plays a role of high quality, high yield and high efficiency. 3. Main feeding habits: Freshwater grouper is a carnivorous fish with a very strong carnivorous characteristic. In the fry stage, it mainly feeds on zooplankton. Fry with large individual differences will kill each other. Therefore, attention should be paid to individual differences during breeding and separate pond management. The small fry after breeding should be fished out in time to avoid being swallowed by the parent fish. It can be trained to eat from the fry, and can eat artificial compound feed. Generally, it can be fed with floating high-protein high-quality fish feed.

2. Feeding and Management

1. Feed management: The newly hatched fry of freshwater grouper is 0.58~0.6 cm in length. They cluster at the bottom of the pond and keep moving. The water temperature is controlled between 26℃~28℃. The yolk sac disappears completely on the 6th day after hatching. The fry swim to the middle and upper water layers and no longer cluster at the bottom of the pond. After the yolk disappears, the small fry can be fed with small zooplankton such as rotifers and cladocerans. When they are slightly older, they can be fed with high-protein pelleted artificial feed for domestication and feeding. After about 1 month of cultivation, they can be put into the pond for adult fish breeding when they are about 10 cm long. In the southern region, the summer time is relatively long. After 100 days of breeding, the weight of fry with a body length of about 10 cm can reach more than 500 grams. The maximum weight of freshwater grouper can reach more than 1200 grams. 2. Reproduction: Freshwater grouper can lay eggs in one winter. The spawning habits are basically the same as those of tilapia. They also dig many ovary holes at the bottom of the pond. Spawning usually takes place in the afternoon. After spawning, the female fish mainly guards the fertilized eggs. The male fish also cooperates in guarding, but as the embryonic development continues, the guarding behavior becomes weaker and weaker until it leaves. The fertilized eggs are oval, dark yellow in color, opaque, and sticky. The eggs are scattered on the bottom of the pond, and there is rarely any overlap. Each female fish can lay more than 3,000 eggs each time. When the water temperature is between 26℃ and 29℃, the fertilized eggs can hatch into fry after 48 hours. 3. Seedling cultivation: Earthen ponds are preferred for freshwater grouper seedling cultivation ponds. Generally, the area of ​​a single pond is 50~100 square meters, and the water depth is 1~1.5 meters. Before stocking the fry, drain the pond water, clean and disinfect the pond thoroughly with quicklime, apply enough basal fertilizer to improve the water quality, breed a large number of zooplankton, so that the fry will have a large amount of natural bait to eat after they are put into the pond. As the fry grow, the food intake increases, and the number of zooplankton in the pond gradually decreases. Soy milk can be artificially fed. When the fry reaches more than 3 cm, their feeding habits begin to change. At this time, fish paste can be fed on the feeding table to start taming. After 2 to 3 days, a small amount of artificial compound feed is added, and the amount of artificial compound feed is gradually increased until all artificial feed is used for taming and feeding. The daily feeding amount is generally about 20% of the fish body weight, and feeding is given 3 times a day.

3. Fish farming

Freshwater grouper can be cultivated in a mixed culture mode. Freshwater grouper is the main culture in the local area. The seedlings are purchased from the south for wintering. The size is 10 cm. The species of mixed fish are tilapia, crucian carp, etc. 300 freshwater groupers are released per acre of water surface, 150 tilapia, 100 crucian carp, and 100 silver carp are mixed cultured. Artificial compound feed is fed during the breeding period. After half a year of breeding, the average weight of freshwater grouper can reach more than 350 grams.
