Floating-type square pond aquaculture system

Abstract

The invention discloses a floating-type square pond aquaculture system which includes a floating body system. A culture net cage is arranged under the floating body system, the culture net cage includes an inner net cage with an opening in the top, a sewage collecting outer net made of silk cloth sleeves the inner net cage, the part, located below the inner net cage, of the sewage collecting outernet is in the shape of a cone, and a square expansion frame is installed at the top end of the cone part of the sewage collecting outer net, so that the top end of the cone part of the sewage collecting outer net is fixed in a square shape. The bottom end of the cone part of the sewage collecting outer net is connected with a sewage pumping pipe, a sewage pump is arranged at the top end of the sewage pumping pipe, a discharge outlet of the sewage pump is connected with a floating-type solid-liquid separation tank, and the floating-type solid-liquid separation tank is connected to a fish and vegetable symbiosis system through a drip irrigation pipe. The floating-type square pond aquaculture system can conveniently collect and treat excretion waste of fish, and can use the waste, the collected excretion waste can be used as a source of nutrient solution for the symbiosis such as fishery-vegetable and fishery-rice or crop land, and environmentally-friendly aquaculture is realized.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a floating square pond aquaculture system. Background technique [0002] With the increasing demand for environmental protection, in the traditional pond culture or cage culture technology, people often ignore the large amount of feed used in the breeding process, feed debris and fish excrement enter the water body, causing a certain degree of pollution to the water environment , resulting in the decline of water quality in many water bodies and increasingly serious eutrophication, which is not in line with green development; while floating aquaculture ponds have problems such as high construction costs and extremely inconvenient fishing. At the same time, the sewage suction equipment needs to be removed when fishing starts. When the water level is reduced or there is no water, the entire floating culture pond will even be deformed or even damaged, and the maintenance operation is comp...

[0002] With the increasing demand for environmental protection, in the traditional pond culture or cage culture technology, people often ignore the large amount of feed used in the breeding process, feed debris and fish excrement enter the water body, causing a certain degree of pollution to the water environment , resulting in the decline of water quality in many water bodies and increasingly serious eutrophication, which is not in line with green development; while floating aquaculture ponds have problems such as high construction costs and extremely inconvenient fishing. At the same time, the sewage suction equipment needs to be removed when fishing starts. When the water level is reduced or there is no water, the entire floating culture pond will even be deformed or even damaged, and the maintenance operation is more complicated and labor-intensive
