CATDOLL : CATDOLL: Which fish are best for raising in rice fields?

1. Which fish are best suited for raising in rice fields?

Carp: It can grow well in shallow water. It is omnivorous and can eat weed seeds, young roots, tender shoots, small underground stems, as well as some filamentous algae and various insects, mollusks, water earthworms, zooplankton, etc. The fry of the same year can grow to 50 grams in two months and 100 grams in three months; the 50-gram fish of the next year can grow to 250 grams in three months. Carp fry are easy to produce and easy to breed and raise, so they are ideal for rice field fish farming. The dull carp in Xiangxi, Hunan, has a gentle temperament. It buries its head in the mud during heavy rains and floods, so it is also called buried carp. It is not easy to escape and is more suitable for rice field farming.

Grass carp: It can also grow in shallow water and eat various weeds. Grass carp are mainly raised in rice fields to provide large-sized fish for ponds, lakes and weirs. When the fry are planted in the fields, they can grow to 50 grams in two months.

Tilapia: Not only is it suitable for living in shallow water, but it is also tolerant to high temperatures, omnivorous, and can eat a lot of algae. The fry can be raised to about 75 grams in a rice field in one season, and is more suitable for stocking in late rice fields. However, since tilapia is a tropical fish, it is not suitable for stocking in cold fields, and it is difficult to survive the winter, so it is not widely promoted at present.

Crucian carp: Generally suitable for shallow water life, omnivorous, easy to produce fry, and has good meat quality.

2. What is the difference between carp in rice fields and artificially cultivated carp?

Rice field carp is very famous. It is more expensive than artificially cultivated ones. After all, it is pollution-free breeding without feeding.

3. How many carps can be raised in one acre of rice field? Does anyone know?

Generally speaking, grass carp, silver carp and bighead carp are all mixed-breeding! Now let's look at the four major carp breeding density in Henan, with the highest density reaching 10,000 jin! Generally speaking, 1 mu of pond can raise 2,000 to 3,000 jin! Of course, as the person above said, the region, climate, environment, water quality, breeding technology and investment are also very different! Of course, it also depends on the water depth

4. How long can carp be raised in 1 mu of rice field?

The stocking species include carp, grass carp, non-carp, crucian carp, catfish, loach, etc. Silver carp and bighead carp can also be raised in the winter idle fields with deep water. They can be raised alone or in mixed culture. Generally, the water in rice fields is shallow, so it is not advisable to raise too many species when raising them together. Carp or grass carp should be the main species, with crucian carp or catfish, etc. The stocking amount of fish varies greatly depending on the combination of rice and fish, the type of fish, and whether or not to feed.

For example, when breeding fish with summer flowers, 15,000 to 30,000 fish are released per hectare; when raising edible fish, 2,250 to 6,000 fish are released per hectare; the upper limit is used for feeding, and the lower limit is used for extensive breeding; when breeding fish in large ditches in rice fields, the stocking density can be appropriately increased. When using winter idle fields to cultivate "summer flowers", 300,000 to 600,000 fish fry are released per hectare, and the rice fields should be disinfected with quicklime 10 to 15 days before stocking.

The wet rice yield of one mu of rice field is more than 1,400 kilograms, which is more than 200 kilograms more than that of ordinary fields. The larger the distance between rice plants, the better the ventilation of the rice field, and also frees up more space for fish to move around. The rice yield will not be reduced, and there is no need to apply fertilizers or pests. If the management is good, it is not a problem to harvest 100 kilograms of fish and 1,000 kilograms of grain from one mu of field.
