Abstract

The invention discloses an aquaculture ecological circulation system which comprises an aquaculture area, a biological bait culture area, a crop planting area, a submerged plant culture area and a filtration and disinfection area which are sequentially arranged according to a water flow sequence and are sequentially communicated through a water pipe, wherein the filtration and disinfection area is also communicated with the aquaculture area through the water pipe to form a circulation water channel, and a fry storage and culture area for storing fries from a fry raising period to a young fish period is also arranged between the crop planting area and the submerged plant culture area. According to the aquaculture ecological circulation system, the fry storage and culture area with the floating bridge and the water planting basket is added in the existing circulation system, so that the fish can be fed in a dispersed mode according to the maturity of fish, meanwhile, the crop planting area is supplemented and purified, the circulating water quality is further regulated to remove organic matters in water, the overall circulation utilization rate is higher, the occupation of a large amount of land by the submerged plant planting area can be reduced, and the economic benefit is higher.

Description

Ecological circulation system for aquaculture Technical Field The invention belongs to the technical field of aquaculture, and particularly relates to an aquaculture ecological circulation system. Background Along with the development of technology and the change of supply and demand systems, for aquaculture industry, scale, intellectualization and systemization are all definite development directions in the future, so that the cultivation mode is gradually changed from private contractual manual cultivation to enterprise planning type large-scale automatic cultivation mode. For large-scale aquaculture, in order to ensure high efficiency of aquaculture, high requirements on environmental protection and high utilization rate of resources, a circulating system matched with a culture pond is often needed, so that culture pollution is prevented and culture efficiency is improved. An ecological circulating water planting and breeding system and a planting and breeding method using the same are disclosed in a patent document with the authority of publication number of CN102835319B, wherein a circulating body is formed by utilizing various areas to filter water quality so as to assist the internal circulation of aquaculture water. However, the method still has some defects, firstly, water flows through the crop planting area and then directly flows into the submerged plant cultivation area, a plurality of ponds are needed to be adsorbed and filtered in the submerged plant cultivation area, the occupied area is required to be large, and a large amount of substances which can be used as feeds, such as organic matters for raising fish fries, in the crop planting area cannot be absorbed by the submerged plant, so that nutrition is wasted, and the raising cost is indirectly increased.
