Crayfish and mandarin fish alternate culture method

Abstract

The invention discloses a crayfish and mandarin fish alternate culture method which includes the steps of preparing of a fishpond, transplanting of water plants, feeding of fish fry, transplanting ofspiral shells, culture management of the fishpond, culture management of mandarin fish, and fishing. According to the ecological habit that crayfish lives in caves in a megathermal period, mandarin fish in the fishpond is cultured in a low density breeding way in the megathermal period. Different varieties are subjected to alternate culture in the same water at alternated seasons, and thus, problems of aging of the fishpond, silt deposition and frequent occurrence of diseases are solved, substance and energy of a fishpond ecological system form a virtuous circle, utilization period and space of unit water is increased, and yield and efficiency increasing is achieved finally.

Description

technical field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a rotation cultivation method of crayfish and mandarin fish. Background technique

[0002] Crayfish are delicious and nutritious, and they are rare freshwater shrimps. The mandarin fish has tender meat, few intermuscular thorns, and high meat content. It is a famous dish on the table. With the transformation of people's diet concept from quality type to nutrition type, crayfish and mandarin fish are more and more favored by consumers. The small dragon breeding time is short, and the monoculture yield is low, resulting in waste of water resources.

[0003] There are many defects in the prior art: firstly, the culture mode is limited to the single cultivation of lobster and mandarin fish in ponds, and in order to pursue high yield and high benefit in the cultivation process, a large amount of feed and medicine are fed, resulting in poor quality of shrimp and manda...
