Embodiment Construction

[0025] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0026] A fish, vegetable and shellfish symbiosis engineered circulating water double-layer culture tank, including a tank body 1, the size specification is 20m (length) × 5m (width) × 2.5m (depth), made of glass fiber reinforced plastics, the top surface is open and located above the water surface , the bottom fish barrier 11 is set inside to divide the water tank into two parts, the upper part is deep and the lower part is shallow. The upper part is 2.1m deep and the lower part is 0.4m deep. There are 21 planting holes with the same diameter.

[0027] The water inlet end and the water outlet bottom of bottom fish fence 11 are respectively provided with a baffle plate 13 with a height of 0.4m. Baffle plate 13 is made of fiberglass. The aperture of fish fence 12 is 7.5mm, which is less than the minimum body height of cultured fish. ...

Abstract

The invention discloses a fish, vegetable and shellfish symbiotic engineering circulating water double-layer culture tank, and belongs to the technical field of aquaculture equipment. The fish, vegetable and shellfish symbiotic engineering circulating water double-layer culture tank comprises a tank body, a floating bed, a bottom fish screen and other structures, the floating bed is located at the top of the water outlet end of the tank body and provided with a plurality of planting holes, aquatic plants are planted in the floating bed, the interior of the tank body is divided into two parts which are deep in the upper portion and shallow in the lower portion through the bottom fish screen, fishes are cultured in the upper tank body, and filter-feeding shellfishes are put in the lower tank body. Through the root systems of the aquatic plants, COD, nitrogen, phosphorus and other nutritive salts in aquaculture water can be effectively absorbed, sedimentation of suspended particulate matter in the water is promoted, meanwhile, granular organic matter is removed through the filter feeding effect of the bottom shellfishes, the problem that an existing aquaculture water tank is low in waste collection efficiency is solved, the yield of the shellfishes and the aquatic plants can be increased, and meanwhile, the landscape aesthetics value is realized.

Description

technical field [0001] The invention relates to a culture tank, in particular to a fish, vegetable and shellfish symbiosis engineered circulating water double-layer culture tank, which belongs to the technical field of aquaculture equipment. Background technique [0002] In order to increase the protection of the fishery ecological environment and reduce the discharge of tail water from pond aquaculture, in recent years, the technological model of pond engineering recirculating aquaculture has been gradually tested, demonstrated and promoted on a large scale. [0003] The pond engineering recirculating aquaculture technology mode is a new type of aquaculture mode. Its principle is to divide the pond into a small water body pushing water breeding area and a large water body ecological purification area. The breeds are concentrated in the water tank, and the water inlet end of the water tank is equipped with an oxygen-increasing water pushing device, and the water outlet end o...
