Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to a high-drop self-water-flowing-tank type fish culture system.
Technical Field
With the continuous increase of world population, water resources can quickly become a factor limiting a plurality of industries, the nutrition cost required by food production will further increase, the demand of southeast Asian countries for high-quality aquatic products will greatly increase, the fishing industry will remain the current situation or be in a descending trend, and the cultured aquatic products will occupy the main market. Meanwhile, the cost of water for agriculture, especially aquaculture industry, is increased, and the environmental pressure is increased. The biggest challenge in agricultural production in the 21 st century is to utilize fewer resources and produce more than 3 times of products. Worldwide bank global fishery program-the initial proposal of the fishery project in year 2030: the world aquaculture amount must be increased by 100% in the future 10-15 years to meet the increasing demands of people for aquatic products.
Pond culture, reservoir culture and river cage culture are traditional aquaculture modes in China, but cage culture is generally suitable for water areas with wide river surfaces and deep water, and the yield per unit area of pond culture is much lower than that of cage culture. In recent years, due to the pressure of ecological environmental protection of China, the net cages of a plurality of large river channels are removed, the traditional pond culture also has the requirements of difficult land property change, severe tail water standard discharge and the like, the culture yield lifting space is small, and the further development of the aquaculture industry of China is restricted to a certain extent.
In order to improve the cultivation yield, a circulating water cultivation technology in a pond is adopted. The circulating water aquaculture technology in the pond integrates the circulating water aquaculture technology and the common pond aquaculture technology, and changes the 'open bulk aquaculture' of the traditional pond into 'intensive containment aquaculture', so that the 'still water' pond realizes 'running water' aquaculture. Through constructing two water flow intercommunication's breed water tank several (one end installs oxygenation equipment and pushes away water and make the flow, one end installs the waste such as incomplete bait fish excrement of dirt absorbing equipment extraction) in pond one side, form annular rivers in whole big pond, can concentrate feeding to fish in "runway" basin, can utilize rivers to concentrate excrement to a inslot unified processing again.
The study shows that the defects of the circulating water culture in the pond mainly comprise three points: firstly, the daily operation cost is high, the circulating water in the pond for cultivating fish mainly depends on the continuous operation of high-power water pushing and oxygenation equipment to provide sufficient oxygen for the fish cultivated in the water tank at high density and to manufacture annular water flow in the pond, the daily power consumption is relatively high, and the operation cost is high; the circulating water aquaculture mechanical equipment in the pond is more, the replacement of the circulating water aquaculture mechanical equipment is easy to damage, the periodic maintenance and repair are needed, and particularly, an emergency power generation system and standby oxygenation equipment are matched for preventing accidental power failure and stopping, so that the cost of manpower and material resources for operation is increased undoubtedly. Secondly, the sewage suction effect of the runway water tank is poor, although the waste precipitation areas such as residual bait fish manure are arranged at the first section of the circulating water tank for aquaculture in the pond, the sewage is sucked by using equipment, but as the residual bait fish manure in the water is always in a suspension state along with the water body, the equipment can only suck a small part of sewage in the water, and if dead fish bodies are encountered, the sewage suction pipeline of the equipment can be blocked. Thirdly, the occupied water surface area is large, the circulating water culture area in the pond is generally not more than 20% of the total area of the pond, the water surface of the rest of the pond is required to be matched with the water for planting purified water plants to treat the culture water quality, otherwise, the requirements of the fish culture water body of the pond runway cannot be met.
Therefore, there is a need to develop a new fish farming system that can reduce the investment, increase the farming yield, and increase the economic benefits.
