Pool culturing composite system with water-saving and safety function

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: [0003] (1), breeding techn...

AI Technical Summary

Problems solved by technology

However, famous, special and high-quality fish require clear water quality, less nutrient accumulation, and large differences among species. Therefore, the technical model of "fertilized fish farming" in ponds is obviously not suitable for high-quality and high-efficiency requirements, and traditional breeding technology has fallen behind. According to the structure and species adjustment needs of modern fishery development

[0005] (2), water resources and material energy cannot be effectively utilized

In order to meet the water quality and ecological requirements of pond cultured fish, the aquaculture wastewater must be continuously replaced and discharged, resulting in a large waste of fresh water resources and loss of available materials and energy

[0007] (3) There are major hidden dangers in the quality and safety of aquatic products

[0008] Due to the incompatibility of the current pond culture system with the increase in culture production, the disease is serious

At the same time, there is a lack of high-efficiency, low-toxicity, and highly targeted aquatic drugs, and commercial vaccines suitable for large-scale fish immunization are also in a blank state

The phenomenon of various antibiotics, hormones and high-residue chemical drugs used in actual breeding production is no longer an isolated phenomenon; the use of non-standard and unscientific drugs has caused the problem of drug residues in aquatic products to become the focus of attention at home and abroad
