Embodiment 1

[0023] In a breeding area of ​​500 mu, the ponds have been transformed, each pond is 10 to 30 mu, and there was no separate inlet and drainage channels at first.

[0024] Apply the technical scheme described in the present invention to carry out transformation, adopt PVC pipes to separate the inlet and outlet water, transform the original 25 mu of water inlet into a tail water purification area, the upstream of the purification area has a planting area of ​​3 mu of bamboo shoots, and the middle reaches of duckweed cover an area of ​​5 mu , the downstream is the planting area of ​​Elodea and bitter algae, 1 mu of Elodea and 1 mu of bitter grass are cross-planted, and they are planted before mid-April.

[0025] The aquatic plants in the pond of the crab breeding pond were planted before December 20 of the previous year, and the planted aquatic plants included Elodea, Erythrophila and Hydrilla verticillium. Elodea accounts for 30% of the bottom area of ​​the pond, Hydra verticill...

Embodiment 2

[0030] A 1083-mu breeding area, the ponds have been transformed, each pond is 10-30 mu, and the inlet and drainage channels are separated. Elodea, bitter grass, and silver carp are planted in the water inlet channel. Plant Elodea, Hydrilla verticillium, and bitter grass in the drainage channels.

[0031] Apply the technical scheme described in the present invention to carry out transformation, carry out ecological transformation of 106 mu of the original inlet and outlet main rivers, plant 6 mu of wild bamboo in the upstream of the tail water purification area, 18 mu of duckweed in the middle reaches, and Elodea and bitter algae in the downstream In the planting area, 1 mu of Elodea is cross-planted with 1 mu of bitter grass, and it is planted before mid-April.

[0032] The aquatic plants in the pond of the crab breeding pond were planted before December 20 of last year. The planted aquatic plants included Elodea, Erythrophila and Hydrilla verticillium. 10%, bitter grass acc...

Abstract

The invention relates to a circulating-water aquaculture system and application thereof, which belongs to field of aquaculture; the circulating-water aquaculture system comprises a culture area, a tail water purification area, wherein, the culture area comprises: crab culture ponds and fish culture ponds; the circulating-water aquaculture also comprises: water-inlet channels and water-outlet channels; the water-outlet channels are arranged both between the crab culture ponds and the tail water purification area and between the fish culture ponds and the tail water purification area, the water-inlet channels are arranged both between the tail water purification area and the crab culture ponds and between the tail water purification area and the fish culture ponds; meanwhile, the water-inlet channels are arranged between the fish culture ponds and the crab culture ponds, the water in the fish culture pond enters the crab culture pond through the water-inlet channel; the advantages of the invention are as follows: due to mixed cultivation of aquatic plants in the crab culture pond for the invention, aquatic plants are ensured to exist during the whole breeding season, and in situ repair function of the culture pond is enhanced; the invention utilizes smaller tail water purification area to obtain purified water of good quality, is economic and practical.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a circulating aquaculture system and an application thereof. Background technique [0002] As an industry, aquaculture solves part of the employment and provides high-protein food. This is indispensable for a developing agricultural country like ours. This is also the reason why my country's aquaculture production has grown exponentially in recent years. While aquaculture requires clean water, it also has a negative impact on water quality. The current situation of eutrophication in Taihu Lake and the outbreak of blue-green algae in 2007 have drawn widespread attention to the pollution discharge of aquaculture along the lake. [0003] The inventor's research team investigated more than 300 crab farmers along the coast of Taihu Lake in 2002-2004. The annual accumulative total of 40kg to 170kg of ice fish was fed, with an average of 100kg; 30kg-270kg of raw grains such as ...
