Technical Field
The utility model relates to a pond culture system especially relates to an intensification pond culture system module, belongs to pond culture technical field.
Background
The pond culture is the most important aquaculture mode in China, accounts for 70% of the total aquaculture yield in China, the Chinese aquaculture pond is mainly excavated and built in the 70 th and 80 th ages of the 20 th century, the facility conditions are laggard, the environment regulation and control capability is poor, particularly, with excessive pursuit of high yield and laggard and extensive aquaculture conditions, the aquaculture environment is polluted, the product quality is reduced, the industrial development is hindered, the pond culture becomes an environment-friendly storm and a hotspot concerned by various communities, and the transformation upgrading and the green development of the pond become the only way for sustainable development of the industry. The pollution of pond culture to water is mainly from feed nutrients which are not utilized by culture organisms, and researches show that only 20-30% of nitrogen and 40-45% of phosphorus in the feed are utilized by the culture organisms, and other nitrogen and phosphorus all enter a culture environment in the forms of residual feed, excrement and dissolved state to become nutrient-rich substances causing water pollution. Therefore, the method improves the utilization rate of the feed, converts nutrient substances into biomass of cultured organisms as much as possible, reduces the proportion of the nutrients entering the surrounding environment, and is the key for solving the problem of environmental pollution of aquaculture.
Increasing the nutrition utilization level of an aquaculture ecosystem is one of effective means for improving the feed utilization efficiency, and the aquaculture pond as a closed ecosystem can prolong a food chain by putting in aquaculture organisms with different ecological niches, so that feed which is not utilized by high-nutrition-level organisms such as cultured fishes is ingested by low-nutrition-level organisms, and the low-nutrition-level organisms are used as bait of the fishes to further improve the conversion of feed nutrition to cultured objects, thereby realizing the purpose of improving the feed utilization rate. At present, the nutrition level of pond culture organisms is few, generally, the pond culture organisms are mainly cultured fishes and mixedly cultured fishes, the mainly cultured fishes are used for generating economic benefits, the mixedly cultured fishes are used for adjusting water quality, the lack of the nutrition level of the organisms in the traditional culture mode causes unsmooth material circulation and shorter food chain, the traditional pond is simple in structure, and if too many culture varieties are put in one pond, the mutual influence of different culture varieties is easily caused, so that the yield is reduced. Therefore, in order to increase the nutrition utilization level, water body interchange between the culture pond and an external water body is needed, and the nutrition utilization level is increased by culturing relevant aquatic animals and plants, but the systematical and overall design of the culture pond is not enough, so that the culture pond is complex in structure and unreasonable in arrangement, the culture system is difficult to construct, and the cost is high.
