This artificial pond will be enough to accommodate for life 2-3 dozen crucians and carp weighing up to 300 g. we Must remember that in the heat of summer the water level can drop, which in turn would reduce the number of fish composition.

If you notice that the fish rose to the surface of the pond, and catches a mouth air, it is a signal that the fish closely, and it lacks of oxygen dissolved in the water. The process of relocation of fish from one water body to another was painless for the fish, and they survived without poteria population, it is necessary to pay attention to the observance of a temperature mode in this case.

Here collects a lot of fish. To fish from such depths is designed and gear. In the oceans and seas, fish are caught using trawls, fyke-nets. In our country fish catch in inland seas.
