Technology of culturing crucian carp in rice field

There are many modes of crucian carp artificial culture, among which rice field culture is a good culture method, which does not affect the growth of rice and can improve the environment of rice field. Crucian carp can eat small insects and plankton in rice fields, which can reduce insect pests in rice fields. The activity of fish in the water is conducive to the growth of rice roots. In short, this way is a mutually beneficial and win-win way. Let's take a look at the details.

1. Field selection

To choose areas with adequate water sources and convenient drainage and irrigation, the terrain should not be too high, just higher than the groundwater level, not too low, the rising water is easy to be washed away. Also not too high, the water is not convenient, easy to drought. Where there is enough sunshine, the water is warm and grows fast. The size of the field is required to be less than 2 mu, and one mu is the best. Sandy loam fields with good water retention are required.

2. Preparation

Before stocking, the ridge of the field should be strengthened, widened and raised, and if possible, you can plant some grass to fix it to prevent the fish from escaping, or the heavy rain can wash out the ridge. Reinforcement can be increased by 60 cm and widened by 10 cm. Irrigation in 40 centimeters can be easy to breed. Cover the omentum at the inlet and outlet to prevent escape, and then dig the fish pit, leaving room for movement. The fish pit is above the inlet, 2 meters wide and 1 meter deep. The fish ditch surrounds the field, more than 30 cm wide and 40 cm deep.

3. Release fish fry

The seedlings should be released in the middle of May, when the growth of rice is stable and then released, which does not affect the growth of rice. The fry should be about two fingers wide and about 6 centimeters long. It is larger than pond culture because the rice field culture time is shorter. To buy seedlings, you must first adapt to the temperature and then put them in the field for breeding.

4. Put in feed

Only eating plankton in water is not enough to satisfy the vegetative growth of fish, so it is necessary to feed regularly, mainly to feed corn meal, soybean meal, wheat bran, soybean dregs, and other food crops mixed into small particles, which can probably be kneaded into a ball after mixing with water. It won't spread out so quickly. Usually feed once or twice a day, feed clean and mildew-free feed. The amount of feed is about the standard that the fish can be eaten in two hours.

The general process of cultivating crucian carp in rice fields is the above, that is to say, to select suitable fields and carry out preparatory work, after putting in crucian carp seedlings, they need to be fed every day to ensure the vegetative growth of crucian carps in the fields and maintain healthy growth. But the whole process can not cause losses to rice, if the effect of mutual benefit and win-win.
