It’s cold and frosty, and, of course, the owners of HOMESTEAD ponds are concerned, is properly prepared their ponds for the winter. However, if certain recommendations of your fish and other pond inhabitants can easily move even the most severe winter.
If the pond is large enough and its depth is more than 1.5 meters, then all its citizens can be safely left in place, through some measures to ensure their safety. Before freezing the water in the pond is saturated with oxygen, and the fish it would be enough for a long time. But the dead leaves of aquatic plants and the waste products of the fish will decompose in cold water and allocate detrimental to the inhabitants of the marsh gas pond.
For saturation of water with oxygen and removal of marsh gas must be cut in the ice hole and to ensure that they did not freeze. In no event it is impossible to break the ice with a hammer or other object. From the strong sound waves can hurt the fish.
To make the hole carefully and all the rules, you can use a simple way, taking a small metal container and adding hot water to gradually melt the ice. You can use the screws – a special device for ice fishing. Keep in mind that the thickness of the ice in the cold if your pond does not covered and will be 40-60 cm
During the winter as little as possible disturb the fish. At low temperatures water pond inhabitants fall into sostoianiia rest (hibernation) and are located at the bottom of the pond. The fish stops feeding and consumes less oxygen.
During the winter definitely check the condition of the hole, prevent it fully freezing. To do this, cover the hole with boards, straw, foam. If you change the color of the water, the foaming, the appearance of hydrogen sulfide odor should immediately identify the cause of changes in water quality and eliminate it. When you fish in the hole should take care of saturation of water with oxygen, adding sprays from the compressor. Also in the hole you can install a pond water pump that will move water from the lower layers, where the water is warmer, to the surface, preventing thus freezing the hole.
Do not install the pump in the deepest places of the reservoir. The warmer water near the bottom, due to increased circulation mixed with cold water the rest of the pond. The optimum bottom water temperature should be 2°C. If it drops to 0.1. -0,2°C, the fish comes a painful condition in which she loses coordination, rises from the bottom and can merznut in ice.
There are other ways of organizing a successful wintering of fish. If fish are few in numbers and small in size, they can be kept in aquariums in winter in heated rooms. But, in my opinion, the best option is the construction of separate wintering pond having a depth of not less than 1.5 meters, the water level should be below ground level at least 30 cm Top is covered with boards, over which is laid a straw or spruce spruce branches. In wintering pond away from water from melting snow or precipitation, it is possible to cover it with slate or plastic wrap. Don’t forget to leave a special viewing window for observation of fish. Even in the most severe frosts in that pond ice is not formed. To be safe you can set a compressor that will enrich the water with oxygen. Before landing fish in wintering pond need to carry out quarantine measures, placing the fish in a 5% salt bath for 15-20 minutes, so that in the pond with the fish not got parasites (leeches, argulus, lerni). Pour in wintering pond only clean fresh water. Transplanted fish pond in the winter, when the water temperature is not higher than 5°C. transplant to the Fish not fed for 2-3 days, so she emptied her bowels.
However, keep in mind that a couple of weeks before the relocation to the new pond the fish need to feed heavily benign vitaminiziruet feed that it has received a sufficient amount of fat necessary for successful wintering. Weak, poorly-fad fish may not recover from hibernation. Even in professional capture fisheries given a certain percentage of the waste on fish in winter.
But not only the fish need your care in the cold season. Need to think about warmth-loving aquatic plants such as nymphea, piste, water hyacinth. They do not tolerate freezing temperatures and will perish in the cold of winter. Move heat-loving plants from the reservoir in the cellar or basement where the temperature does not exceed 5°C. If your nymphs or water lilies planted in containers, it is easy to do. Don’t forget to pre-crop yellowed and old leaves.
Piste and water hyacinth are floating plants in the winter should be placed in a shallow dish with water (thickness of water layer 5-10 cm). If your pond has a seat depth of at least 1 meter, nymphs and lilies can not be removed. Just move the containers with the plants in the deepest place, thus you will rescue nymphs and lilies from freezing.
Such plants as cattail, Buttercup, telorez, arrowhead, water iris, often applied in the design of adjoining bodies of water. They can well endure the winter without outside interference.
If you stick to these recommendations, in the spring of your backyard pond will sparkle with new colors.
