I would like to ask what should I pay attention to when breeding freshwater white pomfret?

Freshwater silver pomfret is a freshwater fish species introduced to mainland my country in the 1980s. It is popular among farmers due to its good meat quality, fast growth rate, easy management and large market sales. However, since freshwater silver pomfret is a warm-water fish, the optimal growth temperature is 15-30℃. When the water temperature is lower than 12℃ or higher than 36℃, it will freeze to death or burn. Therefore, the following technical points should be grasped for the wintering of freshwater silver pomfret fry.

1. Site selection. The pond selected for the wintering of freshwater silver pomfret must be able to maintain a water depth of more than 1.5 meters, the lowest water temperature (in January) can be maintained above 12℃, the area is 1000-2000 square meters, the water source is convenient, the sun is sufficient, and the site is preferably sheltered from the north wind.

2. Set up a cold-proof shed. For ordinary ponds (ponds without hot spring water), freshwater silver pomfret must set up a cold-proof shed for wintering. At present, most farmers use small galvanized pipes and angle irons to weld into a half-moon shape and fix it on the pond embankment; then, cover the shelf with nylon film. The setting position is generally close to the north side of the pond in the north-south direction, and the shed area accounts for about 1/2 or 2/3 of the entire pond. You can also use straw or weeds to clip into a straw mat of 100×130 cm, and then cover the surface of the fish pond on the north side of the pond. The front end of the straw mat is 70 cm away from the water surface, and the back end is close to the water surface. Put some straw under the cold-proof shed. In this way, when a cold wave hits, the fry can gather in the weeds to keep warm. Some farmers use water lilies to stock 1/2 or 1/3 of the pond, and isolate them with bamboo poles to prevent them from growing freely in the entire pond. One of the above measures is to prevent hail or snow from falling directly into the fish pond on rainy and snowy days, alarming the fish and injuring them. Of course, there is no need to build a cold-proof shed for ponds with hot spring water, and freshwater silver pomfret can safely overwinter.

3. Daily feeding and management. During the wintering period of freshwater silver pomfret (i.e., from late November to late February of the following year), whether the feeding and management are in place directly affects the survival rate of spring fish and the overall economic benefits. Therefore, management should pay attention to:

1. Feeding. When the water temperature is above 20℃, the daily feed amount should be controlled at 4%-5% of the fish body weight, and feed in the morning and afternoon; generally use peanut bran or feed containing more than 30% crude protein, soak it before use. When the water temperature is around 15-20℃, the daily feed amount accounts for 2%-3% of the fish body weight, and feed in the afternoon. No need to feed when the water temperature is below 15℃. Feed should be fed in a fixed position in the cold-proof shed, and delivered at a fixed time, location, quality, and quantity.

2. Water quality management. Due to the low temperature in winter, the metabolism in the pond is slow, so the water in the pond tends to become clear, and the transparency is often greater than 30 cm. At this time, some fermented chicken manure or pig manure should be appropriately put into the pond to make the water quality "green, tender and refreshing"; the transparency is about 20 cm.

3. Other matters. During the wintering period of freshwater silver pomfret, try not to go into the pond to catch fish to avoid injuries; it is strictly forbidden to use drugs such as trichlorfon; otherwise, the whole pond will die and the loss will be irreversible.

4. Management in early spring. When the water temperature is stable above 20℃, the appetite of freshwater silver pomfret begins to increase; at this time, it should be fed with concentrated feed and appropriate green feed. Generally, concentrated feed is mainly peanut bran or soybean powder or compound feed containing more than 30% crude protein, and the daily feeding amount is about 4% of the fish body weight; green feed is fed with forage grass or oilseed vegetable, and the daily feeding amount is about 20% of the fish body weight; usually green feed is fed in the morning and concentrated feed is fed in the afternoon. In addition, inject a proper amount of new water into the pond to keep the pond water "green, tender and refreshing", which is conducive to the growth and development of silver pomfret fry and the sale and transportation of spring slices.

Pay attention to the selection of feed and the ratio of feed, ensure the oxygen content in the water, and properly disinfect the fish.

1. Since freshwater silver pomfret has a small adaptability to temperature differences, care should be taken when stocking it to ensure that the temperature difference between the wintering pond and the breeding pond does not exceed 3°C.

2. Generally, the water should be changed 1-2 times a month, and no more than 1/3 of the water should be changed each time. When changing the water, pay attention to controlling the water temperature to keep it above 20°C, and the temperature difference before and after the water change should not exceed 2°C.

3. Before the freshwater silver pomfret enters the wintering pond, strengthen autumn cultivation to enhance its physique and improve its disease resistance. Strengthen feeding, with a daily feeding amount of 6% of the fish body weight and a protein content of 30%. Feed fresh leaves or duckweed appropriately to adjust its appetite. Keep the wintering area quiet and try to avoid scaring the wintering fish. Prevent birds from attacking the fish to ensure that the freshwater silver pomfret has a good wintering environment.

4. After December every year, trawling is not allowed, otherwise it will cause the death of a large number of freshwater silver pomfret. Freshwater silver pomfret is very sensitive to "dichlorodiphenyltrichloroethane", so its use must be prohibited.

First of all, you should choose a pond with good water quality, no pollution, sufficient water source, and convenient drainage and irrigation. Before stocking, you should clean the pond with quicklime and fertilize the water with decomposed organic manure. In daily management, you should pay attention to filling water in stages to keep the water level stable at 1.2-1.2m.

Are silver pomfret, white pomfret, pomfret and flatfish the same kind of fish? How to distinguish them?

Simply put, pomfret is a large category, and silver pomfret is one of the species belonging to this category. White pomfret, flatfish, etc. are all nicknames for silver pomfret.

What kind of fish is Pomfret? Pomfret is a fish belonging to the order Perciformes and the family Pomfretidae. It is short, tall, and flat, and roughly diamond-shaped.

Pomfret is a kind of marine fish that we often see and eat. It is widely distributed in the Indian Ocean and the western Pacific Ocean. There are also a large number of pomfret in the East my country Sea and the South China Sea. The nutritional value of pomfret is also very rich. In addition to the DHA common in marine fish, pomfret is also rich in protein and has a relatively low fat content. Every 100 grams of pomfret contains 15.6 grams of protein and 6.6 grams of fat, which can be said to be a relatively good value. In terms of meat quality, pomfret is very tender and has few fish bones, which is especially suitable for the elderly and children. In addition, regular consumption of pomfret has a relatively good effect on relieving symptoms such as indigestion, anemia, and muscle and bone aches.

What kind of fish is silver pomfret? There are many specific types of pomfret, including silver pomfret, golden pomfret, red pomfret, gray pomfret, etc. Different types of pomfret have subtle differences in appearance and taste.

Silver pomfret, also known as white pomfret and flatfish, is a type of pomfret and also the most common type of pomfret. It is characterized by its silvery-white body, small size and delicate meat.

Compared with other types of pomfret, silver pomfret is more "precious". Whether in terms of price or taste, silver pomfret is the best among pomfret. This is because silver pomfret is basically wild and has not been artificially cultivated yet. In addition, except for the spine in the middle, silver pomfret has almost no other fish bones on its body, and its meat is extremely tender. For silver pomfret, the simplest cooking method is steaming. Since silver pomfret itself has excellent quality, simple steaming can fully highlight its delicious taste, and even a novice in cooking can easily handle it.

Have you figured out the differences between silver pomfret, white pomfret, pomfret and flatfish? Here I would like to suggest that if you want to buy pomfret to eat, it is better to buy silver pomfret, which is simple to cook and delicious!

These names are all nicknames for pomfret, and most people call it silver pomfret. They are the same. The meat of this fish is very tender and very suitable for steaming. The fish skin has a soft and smooth texture. The taste of the fish skin is different from that of the fish meat. It is very delicious.

In fact, they are not the same kind of fish. First of all, their colors are different, then their sizes are also different, and secondly, some of them have very strong smells, while others have very light smells, and most importantly, their prices are also different.

They are not the same kind of fish. Although they are both called pomfret, they live in different conditions, have different requirements for water quality, and have different requirements for food.

In fact, they are not the same kind of fish. If you want to distinguish them, you just need to look at their appearance and the color of their scales. The quality of their meat is different.
