Fish grow in different ways in different rivers, lakes and water environments. However, fish species in many rivers have similar characteristics and behaviors, such as crucian carp, carp, grass carp and silver carp, which are all common river fish. They like to live in clear and mild water and adapt to various water temperatures.
In addition, different rivers can also grow some special fish species. For example, mandarin fish, bighead carp, shad and herring in freshwater rivers can be found in rivers in China. There are fish species such as bean curd fish, four big fish, silver carp and carp fish in the Yangtze River and other big rivers, which have become local specialties.
2, the river water fish nutrients
Fish in river water is rich in high-quality protein and high-quality fat, and also contains many nutrients necessary for human body, such as vitamin B, calcium, iron and phosphorus. These ingredients are very important for the healthy development and metabolism of human body.
Among them, fat is the basis of fish oil. The herring, crucian carp, carp and grass carp in river water are rich in fat, and their fatty acid composition is conducive to enhancing human resistance, preventing cardiovascular diseases and reducing blood lipids.
3. Taboo of river fish.
Although river fish are rich in nutrition, some of them are taboo to eat. For example, when grass carp breeds in spring, it will accumulate a large amount of protein in the stomach, which will make the stomach swollen and the meat hard, which is also easy to cause diarrhea for consumers. Many river fish with poor water environment are easy to parasitize some eggs, and improper consumption will also cause intestinal problems.
Therefore, when we eat river fish, we need to pay attention to the species, growth environment and health status of the fish, especially the healthy river fish stored or cultured. At the same time, we also suggest maintaining good food hygiene and paying more attention to the maturity and umami of river fish when cooking.
4. The significance of protecting fish in river water.
The ecological environment of river waters is destroyed, and the fish resources inhabiting it are also threatened. Therefore, protecting river fish is not only an important part of maintaining river ecological balance, but also the responsibility of protecting human health and biodiversity.
We should try our best to reduce environmental pollution, reduce overfishing and poaching, and protect aquatic vegetation and aquatic insects along rivers such as wetlands and wasteland. Through the improvement of environmental awareness of the whole people, * * * will protect our rivers and lakes with river fish and let them continue to provide us with rich resources and delicious food.
