Crucian carp belongs to the demersal fish, one of the most common freshwater fish in our country. Crucian carp is omnivorous, adaptable to the environment, natural fertility is strong, disease resistance is strong, and its life span is up to more than ten years. Whether it is in freshwater ditches, fish ponds, rivers, reservoirs are often found crucian carp tracks, when we were young often in small ditches to catch crucian carp, at that time there were especially many crucian carp, each time can not catch the end, those earth crucian carp the largest is only two or three, the small is also one or two fingers large. Due to the advanced science in China, after many times of cultivation, the creation of excellent crucian carp, breeding a year of weight of up to 0.5 to 1 kg weight, very popular with farmers breeding. So how to breed crucian carp? Here's how we share our experience with crucian carp farming:
Crucian carp is cultured in fish ponds
The size of the fish pond is required to be 100 square meters and the water depth is 1.2 meters, only in this way can the dissolved oxygen amount be achieved, and the size is not suitable for breeding. In the case of aeration equipment, each cubic of fish production of 50-80 kg, if it is a village free-range fish pond, not equipped with aeration equipment, each cubic fish production of about 10 kg. No matter what kind of management method is used, its water quality should be the most stringent, and the most critical thing for fish farming is the water source, so the clear visibility of the water quality of farmed crucian carp is maintained at 30 cm deep, and it is easy to lack oxygen if it is too concentrated. When the water quality is too thick, the water should be changed in time, or flow into the fresh and clean well water.
Crucian carp is cultured in fish ponds
Stocking crucian carp in fish ponds is much better than farming in fish ponds, whether it is space, environment, water source, dissolved oxygen, they are all well cultured in the form of natural ecological cycles. Generally, in fish ponds, polyculture methods can be used to produce high points of interest, such as polyculture of some silver carp, bighead carp, grass carp, bluefish, mud carp and so on. Fish ponds are divided into live ponds, dead ponds, their stocking density is different, live ponds can produce 10-20 kg of fish per cubic meter, and the backwater ponds are small fish ponds in the countryside, the largest is only two acres, usually free range culture. This kind of fish pond is generally not very feeding, the most suitable for some crucian carp into the breeding, the annual harvest can not be harvested once a crucian carp.
Feeding management methods
Crucian carp is omnivorous and has a relatively simple feeding method, generally feeding with feces and feed, feeding twice a day, around 9:00 a.m. and 6:00 p.m. In the fish pond to breed crucian carp, feces can not be fed, because the fish pond area is less dense, less dissolved oxygen, and the feces salty acid is too high, it is easy to cause the water quality turbidity and lack of oxygen, so in the fish pond is not suitable for manure, can only be fed feed, unless it is a long-running water living pool, can be fed feces. The feed method can not be fed more, and it is mainly necessary to keep eating clean and have no leftovers at each feeding. If crucian carp is cultivated in a fish pond, whether it is manure or feed, the fish pond has a wide space and a small breeding density, mainly a living pond for you to throw manure. If it is a backwater pond in the village, it is necessary to control the amount of manure thrown and often observe the concentration of pond water. In the manure breeding, it is generally recommended to use decomposed fermented manure to be fed, chicken manure and duck manure are most suitable for feeding crucian carp, the main feces are sufficient, and the effect is not worse than feed.
In short, crucian carp is highly adaptable, the growth rate is slow, and the culture is simple and easy to manage. It is an omnivorous fish, mainly eating plant foods, plankton in the water, feces, feed and so on. There are several species of crucian carp, such as silver crucian carp, Pengze crucian carp, Xiangyun crucian carp and other species, like to breed crucian carp friends, choose the right breed for breeding it. I hope that my farming experience will be helpful to everyone, just for reference. Hope to pick!
