How to keep plants and fish in the pond in the winter?
The conservation of pond fish in the winter.
During the construction of pond is necessary to provide in the pond wintering pit with a total depth of 2 m, 2.5 m is better (for Moscow and Moscow region). This hole should easily fit all pond fish. Keep in mind that koi can grow up to 60-70 cm. the Second condition is that the pond never completely covered with ice . Must always be a hole for air exchange. Toxic gases generated by rotting organic matter needs to go outside, the water must be oxygenated. Even two days the concentration of marsh gas can reach concentrations that are dangerous to fish. Constantly punching a hole in the ice is not recommended – you can stun or scare the fish, forcing them to move actively, which is not very good during the rest period. To maintain ice-free polynyas are of special devices . Their main principle of operation is to raise the warmer water layers at the surface, not allowing the ice to freeze. Even better would be to feel the fish, if you equip a small reservoir with an air compressor . His pipes and nozzles should be located near the wells warm – not cold. To install all the equipment, of course, in the fall, before the first ice.
If for some reason, to install electrical equipment should not be necessary for solicitante. However, drilling they need more often that the pond was completely covered with ice. This ice can break up a hammer – the fish can suffer from shock. Emergency the easiest way to make a hole in the ice – put a pan of hot water and wait until it melts.
Before winter clean the pond of dead plants, fallen leaves and other organic substances. Standing firmly the leaves and stems of plants cut a little above the water level, versnum in ice, they will provide additional venting of toxic gases from under the ice. Throughout the summer the fish have to eat well and get all the necessary nutrients and vitamins . The fish should start to prepare for the winter from autumn, and transfer feed with high protein content . If you leave them “graze”, they will not gain weight, and to tamati.
Closely monitor your fish for winter. If the fish is infected with parasites, they are less likely to survive until spring. Still got diseases, the most actively developing during the cold period (chilodonella for example). But the most dangerous part of winter comes with the arrival of spring. Fish, weakened by winter, are more prone to diseases. Therefore, in the fall it is especially important to pay attention to the health of the fish, it is desirable to add a medication for the prevention of diseases of pond fish .
If your pond is not large enough to preserve the fish in winter . they can be transplanted in aquariums and can contain up to spring at home. But let’s say you can’t make a home aquarium. It’s not a problem: the fish survive the winter well even in the basement, and in any sufficiently large and not very deep container (the smaller the depth, the water is better oxygenated). With no soil, no sunlight, no plants. But the water temperature it is desirable to maintain about 10-15 degrees. When the activity of the fish decreases, they eat less, and consequently reduces the secretion of metabolites and the aquarium can be cleaned less often. If the water temperature is about 5 degrees Celsius, the fish will not require feeding, as well as in the pond, go into “hibernation”.
The only additional condition – you will need a filter for water circulation and oxygenation. Need a powerful filter, able in the course of an hour twice to skip all the water. The amount of water depends on many factors: temperature, intensity of feeding, the number of inhabitants. It is believed that the fish length of 10 cm should account for 10 liters of water. But if the aquarium is equipped with a good filter, on an area of 0.5 sq m at a depth of 20 cm can contain up to 20 fish.
After wintering fish released into the pond when the water warms up to 10-15 degrees. In this case, you should try to protect them from shock, which can cause unusual cold water.
How to keep pond plants in winter?
Plants such as water nut and water palm, can easily survive the winter in your pond. Palma water sinks to the bottom and sometimes fixed in the soil with their long roots. Water the palm plant our band, and it remains green even under the ice and can survive the winter, even in ice versnum. Water nut winters similar to Palma, winters long root portion, from which spring new growth points.
Tropical species of floating plants (water hyacinth, piste, Salvinia) overwinter either in the aquarium or in the spring bought new bushes.
