Squid can grow well in shallow water, omnivorous, can eat young roots, shoots, small underground stems of weed seeds, as well as some filamentous algae and various insects, molluscs, otters, zooplankton and so on. When the fish were thrown into the field, they could grow to 50 grams in two months and grow to 100 grams in three months. The 50-year-old fish can be grown in the next year and grow to 250 grams in three months. The production of carp fry is easy and it is convenient for self-cultivation and self-cultivation. Therefore, it is an ideal target for paddy fish farming.
Grass carp can also grow in shallow water and eat all kinds of weeds. The main grass-raising fish species in the paddy field provide large-sized fish species for ponds, lakes and eels. The fish fry in the year can grow to 50 grams in two months.
Tilapia is not only suitable for shallow water life, but also resistant to high temperatures, omnivorous, and can eat large amounts of algae. More suitable for stocking in late rice fields. However, due to the fact that tilapia is a tropical fish, it is not suitable for stocking in cold-water immersed fields, and wintering is also more difficult. At present, promotion is not widespread.
Squid is also generally suitable for shallow water life, omnivorous, fry production, meat quality. In the first season, rice field can develop about 50 grams of edible fish in the same year, which is also a good variety in rice field fish farming.
Which fish are most suitable for paddy fields?
In the past, fish farming in paddy fields was only a few species such as raising carp, carp, and grass carp. At present, many varieties such as tilapia, carp, carp, carp, carp, river crab, loach, macrobrachium rosenbergii, and green prawns have been developed. Can also develop Ping, bamboo shoots, vegetables, edible fungi and other production for integrated breeding. Different regions can choose stocking species according to different circumstances. In principle, all species suitable for pond culture can be cultivated in paddy fields, but paddy fields are generally based on oyster fishes, and some squid and tilapia can also be raised.
