The invention discloses a comprehensive
aquaculture device and a method based on a multi-trophic-level ecological
ditch. An
aquaculture pond is connected with a
filter feeding type fish
aquaculture area through a
culvert pipe, the
filter feeding type fish aquaculture area is connected with an emergent
aquatic plant purification area through a water
filtration partition, the emergent
aquatic plant purification area is connected with a submerged
plant purification area through a water
filtration partition, a water
filtration partition is arranged at the
tail end of the submerged
plant purification area, and a water pump is arranged inside each partition. The aquaculture method includes the steps that the step A,
source water which is acquired on the rim and accords with
fishery water quality standards is pumped into the aquaculture pond through automatic flow or a water pump; step B, the aquaculture mode of combination of high-density
stocking and multiple
stocking and multiple
fishing is adopted; step C and step D, along with arrival of aquaculture seasons, an
impeller type aerator and a water ploughing
machine are arranged in the aquaculture pond; step E, fishes are stocked in the
filter feeding type fish aquaculture area; step F, leakage and water
evaporation are carried out, and standard
source water is added into the aquaculture pond. By means of the comprehensive aquaculture device and the method based on the multi-trophic-level ecological
ditch, structure is simple, aquaculture is convenient to operate, aquaculture yields are improved greatly, and
water area environment is protected.
