In Rivers there are likely fishes etc, that's not the case with still water, as it often goes bad really quickly unless there is a filter installed, which usually also introduces some oxygen into the water etc.
Another reason why Mosquitos usually only use still water is that the surface tension is necessary for them to inject their eggs, and moving water doesn't support their weight
- april_22 4y agoDo you know if there are some rules to how fast the water should be? I know in siberia there are some rivers with suuuper slow speed, you almost can't see that it moves. I know that there are myriads of mosquitos too. Would be interesting to know if there's a connection to water speed and the amount of mosquitos breeding.
