Embodiment 1

[0024] Choose a paddy field with sufficient water source, dig fishing ditches in the paddy field in a cross or well shape, the ditch depth is 30-50cm, the flat area of ​​the fishing ditch accounts for 8% (not more than 8%) of the paddy field area, and the remaining 92% is planted with rice . After the fishing ditch is excavated and built, water is poured into the rice field, and the water surface is about 5cm higher than the surface of the rice field. Carp seedlings are put into the paddy fields, and the size of the seedlings is 600 / kg, and 1000 carp are put in per mu of paddy fields. Put in fish feed and raise it to about 0.25 kg / tail and stop feeding; each paddy field is equipped with pond maintenance products such as protective material (protective material) is a new aquaculture product, purchased from Wu Shuqin of the Chinese Academy of Fishery Sciences. fish farming products), and install a water wheel aerator with a power of 750W; lower the water level before the rice b...

Embodiment 2

[0027] Embodiment 2 Select two paddy fields with the same size as the test field, dig out the same well-shaped fishing ditch, pour water to 5cm above the field surface, and put in a considerable amount of fry. Add pond maintenance products, but continue to feed the feed without showing the field. After the rice is harvested, compare the rice yield with the fish yield. Results Compared with the experimental field 2, the yield of fry in the experimental field 1 increased by 15.6%. The rice yield of the experimental field 2 is 400.5kg / mu, while the rice yield of the experimental field 2 is 280.8kg / mu.

[0028] The test results of Examples 1 and 2 show that the method of the present invention is superior to the traditional culture method in terms of rice yield and fry yield.

[0029] The test results of Examples 1 and 2 show that the method of the present invention is superior to the traditional culture method in terms of rice yield and fry yield.

Abstract

The invention discloses a method for breeding carp fry in rice fields. The method includes the steps of digging fish dishes in the rice fields, pouring water into the ditches, putting carp fry into the rice fields according to the density of 1000 tails per mu, feeding the fry with a feed until the specification of about 0.25 kilogram per tail is reached, equipping each rice field with a pond maintaining product and a waterwheel type aerator, lowering the water level and exposing the field surface before rice flowering so that the normal growth of rice can be ensured, and conducting timely catching and field dividing in the second year for adult fish breeding. Compared with a traditional adult fish breeding method, the method increases the fish yield and also greatly increases the rice yield.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating carp fingerlings in paddy fields. Background technique [0002] Rice field fish farming is an industry that integrates ecological planting and breeding technology by making full use of the space of the rice field, using the natural bait in the field to achieve the mutual benefit of rice and fish, and improving the output of the farmland. However, there are many contradictory problems in rice field fish farming, the most prominent ones are field drying and fish farming, topdressing and fish farming, and pest control and fish farming. Conventional rice field fish farming is to put larger fish fry in the rice field. It has strong adaptability to the environment, but for fish farming, because the fish are small, easy to get sick, and more sensitive to pesticides, it is more difficult and risky to raise fish in rice fields than in conventional rice fiel...
