The thesis deals with the influences that affect water quality in the ponds. It focuses on selected factors which define water quality. These include e.g. the amount of dissolved oxygen in the water, ammonia, etc. To determine the change in water quality in a fish breeding tank, measured quality of water at the inlet of the tank and at its drain. I enter into the analysis and facts about the amount of fish stocking in ponds, basin shape, location of the pond in the countryside, farming in the watershed . |
