CATDOLL : CATDOLL: Is salmon farmed in China?

1. Is salmon farmed in China?

Yes, they generally have very high requirements for water quality. Most of them are raised in spring water, and the water temperature is lower than that required for other fish.

In the famous Longyangxia in the upper reaches of the Yellow River, high-quality salmon are farmed.

No industrial pollution, suitable for the growth of cold water fish such as salmon

China has another world record! A fish farming device built in the Yellow Sea, with an annual output of 1,500 tons

There is breeding

2. Where is salmon produced?

Salmon, also known as Northern trout, king salmon, hunchback salmon, mackerel, and mackerel, is one of the more commonly used fish ingredients in Western cuisine. It is mainly produced in the Atlantic Ocean, Pacific Ocean, American Great Lakes, and Heilongjiang River Basin. It is an upstream migratory fish.

Salmon is a cold-water fish. It lives in freshwater and seawater and is anadromous. The salmon is a cold-water anadromous fish that spawns and migrates. It originally lived in the northern Pacific Ocean and lived in the ocean for 3 to 5 years (usually reaching sexual maturity at 4 years old) before migrating in groups in summer or autumn for reproduction.

According to the time of upstream migration, they can be divided into two groups, summer type and autumn type. Only the autumn type enters the Heilongjiang River in China. Most of them spawn in the downstream, and only a few reach the upstream to spawn.

They travel up the river day and night, working tirelessly, and can advance 30-35 kilometers every day and night. No matter whether they encounter shallow canyons or rapids and waterfalls, they will not retreat and will rush through many obstacles until they reach their destination. Adult fish will not eat after entering freshwater for reproduction.

Buying Guide:

Salmon has well-developed muscles and elastic meat. When choosing fresh salmon, you can identify it from four aspects:

Look at the fish's eyes. If the eyeball is clear and clean, it is good quality. If it is dull, it is inferior.

Look at the gills of the fish. If they are bright red and smell fresh, it is not recommended to buy those with slightly red or gray gill filaments.

Look at the fish body. If it is bright in color, elastic, and intact, it is good. If it is gray, dull, stiff, or dirty, it is bad.

Look at the fish meat. Fresh salmon meat is bright and fresh, shiny, with clear lines and firm texture. Otherwise, it is not fresh.

Taste: Fresh salmon feels firm and full, with abundant fish oil, sweet and fragrant taste, smooth meat, even fat, and not too greasy. The fake rainbow trout, on the other hand, has lighter meat color and is chewier, so it is easy to distinguish them in taste.

Salmon is mainly produced in Japan, Russia, the United States and Canada.

According to the time of upstream travel, they can be divided into two groups, summer type and autumn type. Only the autumn type can enter the Heilongjiang River in China. Most of them spawn in the lower reaches, and only a few reach the upper reaches to spawn. They travel up the river day and night, working tirelessly, and can advance 30-35 kilometers every day and night. No matter whether they encounter shallow canyons or rapids and waterfalls, they will not retreat and rush through many obstacles until they reach their destination.

Nutritional value of salmon:

Farmed salmon and Norwegian salmon contain minerals and trace elements that play an important role in various physiological functions of the human body, such as calcium, phosphorus, iron, manganese, zinc, magnesium, copper, etc. Comprehensive evaluation: Both are rich in nutrients, the crude protein content of Norwegian salmon is higher than that of farmed salmon, and the fat content of farmed salmon is higher than that of Norwegian salmon.

According to scientific research institutions in China and Norway, eating salmon regularly can reduce the risk of cardiovascular and cerebrovascular diseases. Salmon is rich in omega-3 highly unsaturated fatty acids, which can effectively prevent cardiovascular and cerebrovascular diseases and have a positive effect on the health of brain tissue.

Salmon is a type of salmon. Its characteristic is that it lives in rivers and seas, and returns to rivers to lay eggs. There are many places where salmon are produced. Most of the salmon on the Chinese market are artificially produced in Norway. There are also salmon in Heilongjiang, my country, called king salmon.

Salmon, also known as salmon or salmon, is a species of salmon that grows in cold water in high latitudes such as Canada, Norway, Japan and the United States. Salmon has tender meat, bright colors and a smooth taste. In recent years, it has become a delicious dish on the family table. Not only that, salmon also has high nutritional value. In addition to being a high-protein, low-calorie healthy food, salmon also contains a variety of vitamins and minerals such as calcium, iron, zinc, magnesium, phosphorus, and is rich in unsaturated fatty acids. Among all fish, salmon contains the most omega-3 unsaturated fatty acids (about 27 grams per 100 grams of salmon). Nutritional studies have shown that omega-3 unsaturated fatty acids can effectively reduce the incidence of hypertension and heart disease, and are also beneficial to chronic diseases such as arthritis and breast cancer, and promote the growth and development of fetuses and children.

3. What are the possible environmental hazards of large-scale salmon farming?

They have high requirements for water quality. When we choose aquaculture waters, the water must be suitable for their survival and no harmful substances can be present. Breeders with conditions can purchase some water filtration equipment. After filtering the water, the harmful substances in it are gone. Such water can be used to raise fish more safely, because the probability of some special situations will be relatively small. The size of this area should also be taken seriously. The range should be determined according to the number. If conditions permit, try to set the area larger, because this is conducive to the activity of fish. The meat quality of fish that are fully active will also be better. However, you must know that once the range is too large, the difficulty of changing water will also increase, so this is something we have to measure ourselves. They have very high requirements for water quality. How can filtered water satisfy them when changing water? The editor has a suggestion here, which is to prepare a spare pool. The water in this pool is treated. We prepare it in advance, so that when changing water, you can put the fish in this pool first, and then change the water. In this way, the fish will be in high-quality water at any time, and there will be no problems. They will experience hypoxia. At this time, in addition to ensuring the water temperature, we must also prepare some oxygen equipment in advance to replenish oxygen in time when there is a lack of oxygen. The operation must be fast. Once the fish lacks oxygen for too long, it will endanger their lives! If conditions permit, the oxygen equipment can be turned on all the time. Turning it on is only beneficial to them and not harmful. We should also pay attention to the feed that salmon eat when buying it. Go to regular places to buy it. Qualified feed can ensure their health. When feeding, don't feed too much at a time. You can increase the number of feedings. If you feed too much, there will be something left that can't be eaten. It will stay in the water, which is not good for the water quality. This will increase our workload. So feed as much as you eat. Don't say you want them to grow faster and feed them a lot. The consequences of this will make you regret it.
