Fish and other animals in the pond
Fish enliven the garden pond: for their graceful movements interesting to watch. The role of fish in maintaining the balance of oxygen and carbon dioxide in the water is usually exaggerated, while the benefits they offer by eating mosquito larvae, it is difficult to overestimate. However, the presence of fish in the pond is desirable, but not necessary, since usually little impact on maintaining the purity of water.
When choosing fish, primarily guided by the size of your pond. If you are not strapped for cash, you might want to purchase expensive and beautiful koi. Unfortunately, these fish need special conditions – the surface area of the pond not less than 7.5 square metres and a depth of at least 1.2 m. At the other end of the scale are hardy and unassuming goldfish and shubunkin who are able to live with any, even very tiny pond – it is necessary only to ensure that in winter the surface water is not delayed by ice for a long time. Between koi and goldfish is Golden Orff, which required a pond with a surface area of at least 4 sq. m.
Another important consideration is visibility. Motley shubunkin and black telescopes spectacular aquarium, but in a pond they are lost. Better to populate the pond with bright white, yellow, orange and red fish. The most suitable for this is the movable gold zolotarivka and Orpah, because they always stick at the water surface.
When buying fish at the store or market, choose their appearance. Bright color indicates good health – this fish can only be imported recently from abroad. Healthy fish is determined by erect dorsal fin, bright color eyes, intact scales and mobility. Never buy fish with white spots on the scales.
Fish bought in the late spring – early summer, when the water temperature in the pond will reach at least 10 degrees. Better to buy fish of medium size (8 – 12 cm) – care for smaller fish associated with some difficulties, while larger fish are more expensive and quite difficult to get used to new conditions. Buy multiple copies of the same species, as in solitude, fish are restless.
The number of fish in a pond depends on the saturation of water with oxygen, and this is due to the surface area of the pond. Usually when the population of the pond fish adhere to the following rule: 0.1 sq. m of surface water shall be 2.5 cm of body length of fish. When the density of the fish are not crowded and have enough oxygen. At first it is better to run in a pond of goldfish and shubunkin, you can later add other fish species. Carp koi other regulations – one fish at 2.5 square metres of water surface of the pond.
The pond is ready to move the fish one month after planting in a plant. On the way home from the store, the fish are kept in the dark and the cool. Home package with the fish dipped in the pond, in Sunny weather, cover the top of the newspaper. An hour later, unleashing a package and add in some water from the pond. Leave the fish for another ten minutes, then gently release into the pond. Usually fish for several days running, hiding among the plants – don’t try to lure them out.
The fish themselves, find their own food, but if in the spring and summer when they are most active, to feed them, they will grow better and less afraid. Koi can be trained there. Do not overfeed the fish once or twice a day give them this food that doesn’t sink, and after 5 minutes, remove from the water surface at the uneaten portion. Fish can be left safely without food for the duration of your vacation, they will take care of itself.
Your pond will quickly fill with life, and living creatures in it will become more and more as the water attracts frogs, newts and toads, and they begin to throw their eggs.
Many of inhabit the pond living organisms invisible. But visible insects, especially dragonflies, which hover above the water surface. But the age of the adult dragonfly is short – just a few weeks, larvae of dragonflies – and even more actively move in the water. On the surface of the water on long thin legs slip various vodomery, circling whirligig. Some insects live under water, and grabski and beetles can attack the fish.
No doubt, near the pond snails will appear; some of them can cause harm to aquatic plants. Never put them on the pond the pond, which damages the leaves of water lilies. Safe for pond plants only horn coil, while its ability to feed on green algae is somewhat exaggerated. The edentates sometimes recommend to run in the pond for purification of water from small algae, but the pond bottom or no, it is not much use.
Frogs and other amphibians year after year will be printed in the pond offspring. Nice to see the garden grass frog. In the spring she lays eggs, from which about a week later the tadpoles develop. Tadpoles live in the pond four months, feeding on plants and various small animals, including fellows. Ordinary, or toad with dry warty skin look less attractive, but it brings more good garden, large quantities of eating slugs and snails. Toads lay eggs long mucous ribbon, and prefer larger ponds than those that choose for themselves the frogs. Newts are like little lizards amphibians, part time performing in the water. Watch the strange mating “dance” which takes the spring the male of the common newt. The largest of the newts – crested newt – reaches a length of 15 cm.
