Culture requirements of crucian carp

As one of the common fish at present, crucian carp itself is very popular, and its size can basically meet the needs of all kinds of families. In terms of the aquaculture market, it is also good, but those who want to breed crucian carp should pay attention to some problems. Crucian carp farming is also required. Let's first understand and then decide whether to breed crucian carp.

1. Pond requirements

Crucian carp culture ponds generally do not require very large, because crucian carp itself is too small, the pond is large and difficult to manage. A pond is about one acre in size, and it is best to divide the area if it is a natural lake or a large pond in the wild. The bottom of the pond needs to be relatively flat, so the water depth will be more balanced, which is beneficial to aquaculture. It is necessary to disinfect the whole pond before releasing seedlings, and it is best to cycle several times, because crucian carp have poor resistance to diseases. After disinfection, it will be idle for about a week before starting breeding.

2. Water quality requirements

Crucian carp culture site of the water quality is "fat, live, tender" and other characteristics, this is the most suitable water quality conditions for crucian carp, farmers need to adjust the water quality according to this condition. Fertilizer refers to the need for fertilizer and water, and if the water is not fertilised, crucian carp cannot live, so when raising crucian carp, it is necessary to fertilize water first. Live refers to the mobility of the water source, crucian carp itself for water pollution is relatively fast, because of the growth rate, so crucian carp culture ponds need to often change water to maintain the vitality of the water source, it is best to maintain long-term inflow, stagnant water.

3. Reasonable mixed culture

Now mixed culture is the core of fish culture, the final effect of a single culture of certain fish is not ideal, because the ecology of the culture pond is easy to be out of balance, and this is especially obvious in crucian carp, so mixed culture of crucian carp as far as possible. Mixed fish can not be too different from crucian carp, it is better to be close in size, so crucian carp is not easily threatened. Secondly, the total proportion of mixed fish species had better not exceed 30%, too much will affect the normal growth of crucian carp.

4. Control density

Crucian carp culture density has always been a place that we pay more attention to, in fact, there is no particularly detailed standard at present, mainly according to everyone's actual area. Generally speaking, the Mantissa per mu is controlled at about 1300-1600, plus mixed fish species, the overall number is about 2000, this number is a more appropriate level. During the period to pay attention to the movement of fish, if there is often a floating head, it may be a high density leading to a lack of oxygen.

These are some of the requirements for farming crucian carp. We should consider these problems when we breed, so as not to have problems with our own farming. Breeding this thing still depends on the actual situation, we can change it appropriately.
