Breeding fish in the pond
With the appearance of the garden pond there is an understandable desire to populate its inhabitants, and to contemplate his troubled life. If you do not do this on purpose, after a couple of months the reservoir is mastered by the water striders, Daphnia, snails, beetles predaceous diving beetles, larvae of dragonflies, leeches, frogs and even small fish – roach, bleak, upperka. If the fish didn’t start itself, you can bring a trifle from a nearby natural reservoir for the formation of a complete ecosystem pond. However, even these fish, despite their modest size, have good appetite and can cause significant harm to the precious aquatic vegetation, so first I have to make a choice between fish and plants, or be limited to those species that are not eaten by fish.
If you allow the size of the pond, you can pay attention to the larger representatives of ichthyofauna. Very attractive with their bright varied coloration and calm disposition Japanese koi . These gregarious fish often swim to the water surface and to person and gives pleasure to watch them. But are they “hooligans” – lift up the bottom sludge and damaging the plants. For the winter they need sufficient depth – not less than 2 m, or moving the pond in winter garden. So those who have not, have to choose local species.
Often used in many natural waters carp, crucian carp . perch . of these, the last is the most demanding of water quality. Bass are predators, and very voracious, per 1 kg of weight have 5 times more food eaten, so the course is all coastal wildlife – insects, crustaceans, larvae, leeches, and even their own young, except frogs and large tadpoles. Perch cleans the pond, unpretentious. Hunts during the day, so well seen at night drops to the bottom.
People carp are bred in artificial ponds has long been, they were imported from China during the time of Ancient Rome. Carp ( carp ) is a vegetarian, which is rare among fish, 1 kg weight he needs 3-4 kg of feed. Lives in small flocks in all waters, standing or slow-flowing, preferring deep water with driftwood and clay bottom. It feeds morning and evening, and at this time loves to splash around. It’s a bold and smart fish, well tame, eagerly swims to the person in anticipation of treats. Each individual has its “face” and is recognizable thanks to the white growths on the head. Displayed are some breeds of carp – mirror, ramcity (with fewer scales) and skin (without scales). The most beautiful is the mirror, which, living in the water column, becoming silvery shades, and the bottom is Golden.
Also, how the carp behave in a reservoir other carp – tench , IDE . However, Lin is less noticeable in the pond, because its color depends on the color of water. IDE – omnivorous fish is unpretentious, witty, and carp. Best look for a small flow of cold water.
Carp – a leisurely fish prefers to live in stagnant water with Tina, where to obtain its food. In Tignes it survives the winter even if the pond freezes to the bottom. There are varieties of carp – gold and silver, which are found in the same population. Noticed that the silver carp, the number of females dominates males. About 1000 years ago in China from silver carp has been bred well-known goldfish . which is the variety of color and calm disposition. It is a good choice for a small pond, but you need to ensure that the water is not overheated. For the winter determine goldfish in a big aquarium.
Recently increased the number of people willing to breed in a garden pond valuable cartilaginous fishes – sturgeons, starlet . They are representatives of an ancient group that lived 100-200 million years ago. Typical freshwater inhabitants, they are not particular about conditions, about the same as carp. In contrast to the prolific carp, the name of which comes from the Greek “Karpos”, which means the fruit, sturgeon never spawn in ponds, but faster than in natural conditions, gain weight. However, this does not make them more visible. During the day these fish hide in the depths, burrowing and often merging with the bottom due to cryptic coloration. Surveying the seabed in search of benthic inhabitants that serve them as food, greatly muddies the water. They can be observed rarely, only at night, so muddy pond with sturgeon will not give aesthetic pleasure, but rather will remain merely a element of prestige. In order to revive this water body, recommended to run together with other sturgeon, more visible and moving fish.
A good contender for this role is rainbow trout . It is quite large, pretty fish, with bright silvery color with crimson stripe along the body and Gill covers. It feeds in the water column small invertebrates, often jumping out of the water, preying on flying insects and showing himself. Does not violate the transparency of the water stirs the silt. The noise responds not with fear but rather curiosity. For keeping the trout pond needs to be deep enough, since this fish does not tolerate overheating the water. Winters in the pond, keeping active, and therefore requires the maintenance hole, where it is periodically swallowed oxygen.
The stocking of the reservoir contributed to the formation of a balanced ecosystem pond, and has been the cause of disappointment and loss, you must consider many factors:
The suitability of a pond for breeding fish is not always determined by its depth, the more significant is the surface area of the water allowing its oxygenation.
Fish are better to buy in safe places to avoid the spread of disease.
The correct selection of species and quantitative composition of ichthyofauna, preventing overpopulation of the pond. It is known that water shall be not less than 50 liters per one medium-sized individual.
