Ecological fish farming method and device based on ditch and pound compound system

Abstract

The invention discloses an ecological fish farming method and device based on a ditch and pound compound system. The method comprises the steps as follows: A, source water which accords with a fishing water quality standard and acquired in a sounding area through automatic flowing is pumped into an aquaculture pond; B, an aquaculture model combing high-density stocking with multiple stocking and multiple fishing is adopted; C, the aquaculture season approaches; D, an impeller type aerator and a water cultivator are arranged in the aquaculture pond; E, different aquatic economic plants are planted in sections in an ecological ditch; and F, leakage and water evaporation occur, and water is supplemented into the aquaculture pond. The aquaculture pond is connected with the ecological ditch through a water pump, water outlet at the tail end of the ecological ditch is connected with the aquaculture pond through a water collection pipe, an escape-proof net is arranged at a water inlet end of the water collection pipe and a water level control pipe is inserted into a water outlet end; and the aquaculture pond adopts a prefabricated concrete protection slope, creasing is performed with bricks at the top of the slope, a concrete foundation beam is added at the bottom of the slope, and the ecological ditch is arranged around the aquaculture pond. The structure is simple, the aquaculture is convenient, the aquaculture yield is remarkably increased, the environment of the water area is protected, and water resources and material energy are recycled.

Description

technical field

[0001] The invention belongs to the technical field of aquaculture, and more specifically relates to an ecological circulation aquaculture method using an ecological ditch as a water treatment unit, and also relates to an ecological fishery aquaculture device based on a ditch-pond complex system. Background technique

[0002] Pond aquaculture is the main body of my country's aquaculture industry, and it makes a significant contribution to freshwater aquaculture. However, the traditional aquaculture methods of high density, high feeding rate, and high water exchange rate used in pond aquaculture have had adverse effects on the internal and external environment of aquaculture, and have become a bottleneck restricting the further development of pond aquaculture. The outstanding problems faced by pond culture are listed as follows:

[0003] (1) The pool ridges are generally collapsed and the aging phenomenon is serious

[0004] Most of the aquaculture ponds in ...
