Problems solved by technology

[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

Embodiment 1

[0016] Embodiment 1: a kind of polyculture method of crucian carp and bighead carp, beautiful white shrimp, fish pond area is 5 mus, and breeding process comprises the following steps:

[0017] (1) Disinfection of the clear pond: Before the fry are stocked, the pond is kept at a water depth of 10 cm, and a total of 500 kg of quicklime is used to disinfect the fish pond.

[0018] (2) Water quality for fertilization: Inject 1.0 meters of water into the fish pond, filter the water inlet with 80-mesh silk screen, and apply 100 kg of fully fermented cow dung per mu of water surface after 3 days.

[0019] (3) Adjust the PH value: Use quicklime to control the pH value of the water quality to 7.8.

[0020] (4) Fry stocking: 7 days after water injection, the water quality becomes fatter. At this time, fry are stocked. The fry include crucian carp summer flowers and bighead carp summer flowers. Among them, there are 17,500 crucian carp summer flowers and 2,500 bighead carp summer flower...

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.
