Embodiment 1

[0022] In a 500-mu river crab farm, the ponds have been transformed, each pond is 10-30 mu, and there were no separate inlet and drainage channels at first.

[0023] Apply the technical scheme of the present invention to carry out transformation, adopt PVC pipes to separate the inlet and outlet water, transform the original water inlet channel into a tail water purification area of ​​25 mu, the first-level purification area is 3 mu, plant wild rice stems, and the second-level purification area is 5 mu , planting purple-backed duckweed, 17 mu in the third-level purification area, planting Elodea, Hydrilla verticillium and bitter species, the area ratio is 50:25:25, cross-planting, and it will be planted before mid-April.

[0024] 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 p...

Embodiment 2

[0029] 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.

[0030] The technical scheme of the present invention is applied to carry out transformation, and the 106 mu of the original inlet and outlet main channels are ecologically transformed into a tail water purification area, which is divided into three stages by damming, and the culvert pipes are connected. The first-level purification pool is 12 mu, planted with water spinach; the second-level purification pool is 25 mu, planted with purple-backed duckweed; the third-level purification pool is 69 mu, planted with Elodea, bitter grass, and Hydrilla verticillium, and the planting area ratio of the three aquatic plants is 50: 25:25, cross planting, planted before mid-April.

Abstract

The invention belongs to the field of aquaculture, and particularly relates to distribution of an environment-friendly aquaculture farm, which includes a fish culture area, a river crab culture area and a tail water purification area from the upstream to the downstream. Tail water from the fish culture area is drained to the river crab culture area, the tail water from the river crab culture area is drained to the tail water purification area, and water from an outlet of the tail water purification area is then diverted into the fish culture area. The water in the river crab culture area can also be diverted into the fish culture area directly, and the water in the fish culture area can also be diverted into a primary purification tank in the tail water purification area directly. By using the distribution, the area of the tail water purification area can be reduced, the quality of river crabs can be improved, and recycling of culture tail water and nutrient pollutant can be achieved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to the layout of an environment-friendly aquaculture farm. 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] In order to reduce farming pollution, we first conducted a survey on the intensity of farming pollution. The research results showed that the pollution of pond culture was mainly nitrogen (N) and phosphorus (P) pollution. To realize the reduct...
