Fish kill to a certain extent is natures way of getting rid of the sick and weak fish. However, if you start seeing larger than normal levels of fish washing up on the side of your pond then you may have a serious issue. The number one cause for Fish Kills is the depletion of oxygen within a pond's waters.
Fish kills due to lack of oxygen in a pond will most often occur in the really hot months of Summer or Cold months of Winter.
In the hot summer months, the levels of oxygen in the pond are reduced because of the higher amounts of decaying dead plant material which tends to be more active during this time of year.
Pond algae is usually more predominant in the hot summer months as well. A certain amount of Algae in a pond is said to be healthy for it can produce food for pond inhabitants. When there is an overabundance of Pond Algae then the sun light cannot penetrate through the water's surface to reach the plants who in turn create oxygen through the process of photosynthesis.
In the cold winter months the lack of oxygen in the water is usually caused by snowpack on top of the ice. This ice build up limits penetration of sunlight to photosynthesize plants within the pond.
Fish stressed from low oxygen levels, can frequently be observed gulping for air at the pond surface. An extremely cost effective way to prevent Fish Kill is Pond Aeration.
By aerating your water you will be injecting oxygen into your pond to help increase the level of dissolved oxygen. Koenders Windmill Aeration Systems are the most reliable cost effective way to keep your pond healthy and clean and your fish alive all year round.
