Perhaps it will be agriculture, where the cultivation of fish will be your main activity or fish farming will become an integral part of the farm with the use of the reservoir complex. The latter area has received wide distribution as well as cultivation of fish goes well with other branches of agricultural production. Hence in the construction of the pond should not exclude the possibility of comprehensive use, for example for watering livestock, watering the garden, fire fighting purposes, breeding waterfowl.
