Fall circulation type land pool fish culture process

Abstract

The invention relates to the technical field of cultivation, in particular to a fall circulation type land pool fish culture process. In order to solve the problems about automatic detection on the water quality of the land fish culture pool, no equipment for increasing gas, water cyclic utilization and environmental protection of discharge water, the process comprises a farm area and is characterized in that a water storage early-warning pool is arranged at a water inlet of the farm area; the farm area is divided into an upper half area and a lower half area; water passing through the water storage early-warning pool enters the upper half area of the farm area; the height difference between the upper half area and the lower half area is more than or equal to 1 m; the upper half area is provided with a return water channel; a return water treatment pool is arranged at the tail end of the return water channel; the return water treatment pool is a round pool; a supporting frame is arranged in the middle of the return water treatment pool in the height direction; a gravel layer is arranged above the supporting layer; a buffer pool is arranged beside the return water treatment pool; and the bottom of the buffer pool leads to the lower half area. The process has the advantages of water using safety, obvious oxygen-increasing effect, cyclic utilization of water resources, environmental friendliness and energy conservation.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a fish farming process in a drop circulation type land pond. Background technique [0002] "Fish should be raised with water first", good water quality is a necessary condition for healthy and rapid growth of fish. The water quality before fish farming must pay attention to the sum of various indicators and parameters of the water body, including pH, hardness, salinity, water temperature, dissolved oxygen, ammonia nitrogen concentration and other indicators. Environmental protection and energy conservation must also be considered. There are many structures and technological forms of fish ponds in the prior art, each with its own characteristics, but each has advantages and disadvantages. For example, the patent notification number is CN201504489U, which relates to a clapboard precipitation type circulating water fish pond, including filter box, filter cotton, support, water pi...
