Abstract

The present invention relates to a pond cultivation combination system with water-saving and safety function, belonging to the field of aquaculture technology. Said system is composed of fish pond, artificial wet land and canal which are mutually communicated by means of water flow. The fish pond, artificial wet land and canal are successively series-connected so as to form the invented stereoscopic multi-stage utilized, closed and circulated pond cultivation combination system. It is characterized by that it can make waste water of fish pond be passed through artificial wet land and canal to purify water quality, increase dissolved oxyger and change static water of fish pond into microflow water to make cultivation so as to attain the goal of implementing high-effective cultivation of fishes and saving water resources.

Description

Technical field:

[0001] The invention relates to a pond culture system, in particular to a pond culture composite system with both water-saving and safety functions, belonging to the technical field of aquaculture. Background technique:

[0002] In our country, pond culture, as the main body of the aquaculture industry, has not only made great contributions to solving the difficulty of eating fish for the people, but also has become a strong industry to solve the "three rural" problems and build a new countryside. According to statistics, in 2005, the pond aquaculture area accounted for 42.9% of the freshwater aquaculture area, and the aquaculture output accounted for 70.3% of the freshwater aquaculture output. However, for thousands of years, pond aquaculture in my country has been using tidied or manually excavated still water with a small area for fish farming. However, this traditional pond aquaculture method has the following disadvantages:
