Method for mixed culture of crucians, bighead carps and exopalaemon modestus

Abstract

The invention discloses a method for culture of crucians, bighead carps and exopalaemon modestus. The method is characterized by comprising the following steps: pond cleaning and sterilization, water quality fertilization, PH value regulation, fry addition, young shrimps addition, bait feeding, water quality regulation, execution of an oxygen enrichment measure, aquatic plant feeding and the like. According to the method, the proportion of the crucians and the bighead carps is reasonably matched, so that baits can be fully utilized, and surplus baits can be digested by the bighead carps to avoid environmental pollution; the excessively fed baits are finally digested by the added young shrimps, so that waste of the baits is avoided, meanwhile, higher value is created, and an ecological environment and a food chain in a fishpond are maintained; aquatic plants are fed, so that cultured fish is closer to wild fish, the cultured exopalaemon modestus is closer to wild exopalaemon modestus, the meat quality of the fish and the exopalaemon modestus is improved, and meanwhile, the ecological environment in the fishpond is protected.

Description

technical field [0001] The invention relates to the field of fishery production, in particular to a method for polyculture of crucian carp, bighead carp and white shrimp. Background technique [0002] At present, with the continuous improvement of people's living standards, the food demand for fish and shrimp is also increasing, especially crucian carp, bighead carp, and beautiful white shrimp, which are very popular fish and shrimp products. Crucian carp is famous for its tender meat. The fish head soup of bighead carp is widely praised, and the Xiuli white shrimp is very popular because of its strong umami taste and rich nutrition. However, most of the existing crucian carp, bighead carp, and Xiuli white shrimp are cultivated in a single way. Farming, not only the yield is low and unstable, but also the amount of feed is used more frequently, and the amount of feeding is relatively large; the quality of fish meat of crucian carp and bighead carp produced in this way is muc...

[0002] At present, with the continuous improvement of people's living standards, the food demand for fish and shrimp is also increasing, especially crucian carp, bighead carp, and beautiful white shrimp, which are very popular fish and shrimp products. Crucian carp is famous for its tender meat. The fish head soup of bighead carp is widely praised, and the Xiuli white shrimp is very popular because of its strong umami taste and rich nutrition. However, most of the existing crucian carp, bighead carp, and Xiuli white shrimp are cultivated in a single way. Farming, not only the yield is low and unstable, but also the amount of feed is used more frequently, and the amount of feeding is relatively large; the quality of fish meat of crucian carp and bighead carp produced in this way is much different from that of wild carp, and the amount of feed is large, which can easily lead to water pollution. Affect the environment and cause waste of feed
