Breeding fish in ponds.
If your site has a pond, you can breed fish. Fish farming in ponds is an interesting and profitable occupation. Almost everyone in my childhood was the aquarium. However, not all have kept this hobby for life. But it’s not terrible. Importantly, the idea of breeding fish in captivity.
The fish habitat is water. This is for anybody not a secret. But few people know exactly what should be the water that the fish stay away. If you were observant, you might notice: a large grassy puddle, and her boys caught a whole bunch of carp. Or another example is a large lake with picturesque shores, and no matter how much I wait with bait – no one bites. What is the reason?
Back to the aquarium. Remember, if the water in the aquarium began to thicken – the fish began to die. Besides, you regularly use the microcompressor, enriching the water with oxygen. Sometimes heated up the reflector, so that your animals did not freeze. Tried time to feed, feed purchased, depending on the species of fish. In a pond all the same. The fish grew and bred, she needs pure water enriched with oxygen. The water temperature must conform to a certain norm. Keep in mind that the fish in the cold is not propagated. Even fish need a good forage base.
The basis of life of fish is oxygen. Oxygen fish breathe. Without it, no nourishment, or reproduction of fish. In natural vodoemov oxygenated in the process of exchange with air masses. As the oxygen is isolated and some algae. Basically it is a seaweed green color. The oxygen is released by algae during daylight hours only. This distinguishes them from green plants. In the period of flowering water, in very hot weather and with the stagnant phenomena in the pond (when disturbed the natural water purification), and in the winter, when reservoirs are ice-covered, oxygen can not miss. This can cause massive marine fish. It is therefore necessary to monitor the oxygen content in the water. The oxygen content should be for trout and other cold-water fish 5-7 cm3, for carp and herbivorous fish is 3.5-5 cm3 in 1 liter.
The water in the ponds for cultivation of fish must be clean. In polluted bodies of water formed methane and hydrogen sulfide, which is harmful to fish life. The formation of these gases can be identified by a characteristic smell. Most often it is formed in hot weather, the flowering period of water. To prevent this phenomenon need to clear the bottom of the pond from silt and excess vegetation. It is possible to apply the draining and burning of algae.
The water in the reservoir should be neutral. Invalid water with acid content. If the PH is below 7, water is acidic. In this case, you need a liming.
Minerals – fluorine, nitrogen, potassium, calcium and others necessary for plant growth and development. In natural waters these substances enter water that is passing through the earth, dissolves them. Minerals contribute to the growth of plants, and the plants in turn are food for fish. Thus, if the water lacks minerals, they need to be entered separately.
Fish can be breed in natural water bodies. This can be a small lake, flooded ditch or something else. The main thing is that the water in the pond did not dry up. And it is possible to breed fish in a specially dug and equipped pond.
A pond can be dug, but you can create based on an already existing groove. In this case, find a natural depression filled with water, left over from the drying bed of the former river or stream. Block it high from one end to the other by a Causeway. Gradually, in this place accumulates water. It can appear a number of nearby spring or in the result of accumulation of rain water. This makeshift pond will be quite suitable to fish farming.
What are the requirements for a pond? The pond bottom should be smooth, there should not be grooves. Otherwise this will lead to waterlogging of the soil. Growing near the shore or bed of the pond plants should be cut down. Otherwise they will contribute to the overgrowth of the pond.
If there are keys, springs, and any exits to the surface of groundwater – they must be clear to ensure the flow of water. It is desirable to make the pond drain. This will help the fish, and if necessary the restoration work in the pond.
What fish can be reared in ponds? Gully ponds – the most common type of ponds. They are constructed in low valleys or the dry ravines. These ponds of stagnant or slaboprotochnyh. The water is well warmed up. The bottom is heavily silted. They have good forage base. These ponds are an ideal place for breeding of carp, tench, painting, perch.
Park ponds are also suitable for fish farming. They are well bred ticking. But before the landing of fish these ponds require a specially preparation: cutting close-growing trees, clearing the bottom, the installation of bottom outlets.
Very good a feeding fish is a reservoir. This large reservoirs, with an area of several hectares. Requirements are the same as the other ponds. They are a good breed bream, carp, carp. You can also drop off the perch, trout, whitefish, whitefish, sturgeon, etc.
For fish you can use an abandoned quarry. But they need to provide good-quality water. Only under this condition they become suitable for the breeding of crucian carp, pike and other fish.
