Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] The construction of the floating basket: such as figure 2 As shown, use the Φ50 PVC pipe to build the skeleton of the floating basket. The bottom is a rectangular frame, and a PVC pipe is bound in the middle of the rectangular frame as an isolation fence. One end of the rectangular frame is vertically 90° and then a rectangular frame is bound, and the floating basket is built. it is good. It should be noted that the design of the floating basket skeleton of the present invention can also be improved and modified without departing from the principle of the present invention, not limited to figure 2 the shape shown.

[0016] Such as figure 1 As shown, the dredging of the ditch requires gentle slopes to be set up at the banks of the ditch, and several pairs of floating baskets 4 are respectively set up along the banks of the ditch. For crabs, water peanuts are pla...

Abstract

The invention discloses a mixed culture method for fishes, prawns and crabs in a reed zone ditch. The mixed culture method includes the steps: dredging the ditch; setting gentle slopes; respectively setting a plurality of pairs of floating baskets along two banks of the ditch; planting Vallisneria natans, Elodea nuttallii and Hydrilla varticillata in shallow water zones with the floating baskets close to the banks to culture the prawns and the crabs; and planting Alternanthera philoxeroides in deep water zones with the floating baskets. The fishes are cultured between paired floating baskets. The Vallisneria natans, the Hydrilla varticillata and the Elodea nuttallii can effectively purify water, improve the ditch and serve as baits of the prawns and the crabs, the Alternanthera philoxeroides are clustered in summer to provide a protection place for shelling of the prawns and the crabs, the fishes, the prawns and the crabs are effectively isolated by the Alternanthera philoxeroides, and harm of the fishes and other natural enemies is prevented.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for polyculture of fish, shrimp and crabs in ditches in reed areas. Background technique [0002] The ditches in the reed area are mostly reclaimed for irrigation or formed naturally during the construction of farmland. At present, most of them are contracted by the common people to raise common freshwater fish such as silver carp and grass carp, feed some agricultural feed, and then sell the economic fish. Due to the low value of these fish, the effect of growing in ditches is not necessarily good; on the other hand, due to improper management of many ditches, the water quality of the water body is already very poor, making it difficult to carry out aquaculture. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a method of utilizing rural ditch resources to polyculture fish, shrimp and crabs, and isolate fish, shrimps an...
