Compared with other waters, highland freshwater lakes have relatively fewer organisms.


Due to the dry climate and scarce water resources in the plateau, coupled with the higher altitude and lower water temperature, the species and the number of organisms in plateau freshwater lakes are relatively small.


At the same time, the water bodies of plateau freshwater lakes are clear, with high transparency and relatively good water quality, so the biological species in plateau freshwater lakes are also relatively pure and special.


The common highland freshwater lake organisms include various kinds of fish, algae, plankton, and so on. In the surrounding areas of the plateau freshwater lake, some unique plateau animals can also be found, such as Tibetan antelope, Tibetan wild ass, plateau rabbit, etc.


Plateau freshwater lakes have certain effects on the survival of fish, but they are not necessarily all unfavorable.


1. Water temperature: Due to the high altitude of plateau freshwater lakes, the water temperature is generally low, which is a suitable survival environment for some fish. However, too low or too high a temperature can negatively affect the survival of fish.


2. Dissolved oxygen: The dissolved oxygen level in the water of highland freshwater lakes is low, which is unfavorable for some fish that need high oxygen water environment.


3. Water quality: The water quality in highland areas is usually clear, but if it is polluted by human activities, the water quality may become poor, which will hurt the survival of fish.


4. Food: Food resources in highland freshwater lakes are relatively small, and fish that need to adapt to this environment may have some competitive pressure.


In conclusion, highland freshwater lakes have some impact on the survival of fish, but it is not completely detrimental. Fish that have adapted to this environment can still survive and thrive in them.


The following are some common highland freshwater lake fishes:


1. Carp: It is one of the most common fish in the highland freshwater lake, with large size and delicious meat.


2. White bream: It is also a common fish in the highland freshwater lake, with a large size and delicious meat.


3. Silver carp: It is a common fish in the highland freshwater lake, with a small size and tender meat.


It is worth noting that the number and species of fish in the plateau freshwater lakes may vary with the seasons and years due to the influence of the environment.
