Tilapia can be both river and sea fish. Tilapia is native to Africa and is a tropical fish. It is suitable for living in freshwater basins at low latitudes and relatively high water temperatures, so it thrives in rivers, lakes and ponds in Africa. In these areas, tilapia lives mainly in freshwater environments and is therefore considered a river fish.
However, with global climate change and the impact of human activities, the habitat of tilapia has expanded to many parts of Asia, Europe and the Americas. In these new habitats, tilapia also lives in both freshwater and saltwater waters, especially in the Mediterranean, Aegean and Gulf of Mexico. In these seas, tilapia can adapt to the high salinity environment and reproduce successfully, so it can also be considered as a marine fish.
In addition, tilapia's physiological structure and ecological Xi also make it suitable for living in both freshwater and saltwater environments. For example, their gills and kidneys can effectively regulate the salt balance in the body, allowing them to maintain normal physiological functions in different water environments. So,Tilapia can be both river and sea fish.
This statement arises because tilapia is a tropical fish with the characteristics of fast growth, miscellaneous diet, few diseases, and strong fecundity. They can survive in a variety of waters, including some of the more polluted ones. As a result, some people believe that tilapia is a "scavenger" that absorbs contaminants from the water.
However, this does not mean that all tilapia are grown in polluted water. In fact, tilapia that has passed the quarantine can be eaten with peace of mind and does not have a particularly dirty problem. At the same time, tilapia is also rich in nutrients, such as protein and unsaturated fatty acids, which are beneficial to human health.
Of course, there may be some risks associated with consuming tilapia for some groups of people. For example, children under the age of 3 and people with high cholesterol should avoid tilapia. In addition, people during periods of cold and fever should also avoid consuming tilapia to avoid causing physical discomfort.
In conclusion, tilapia is not dirty and can be eaten. However, before consuming it, it is best to choose tilapia that has passed quarantine to ensure its quality and safety. At the same time, it is also necessary to pay attention to the nutritional needs and physical condition of the individual, and consume tilapia reasonably.
