Description
Technical field
The utility model relates to the technical field of aquaculture, specifically a kind of high drop gravity flow water tank type fish farming system.
Background technique
As world population is being continuously increased, water resource can be quickly become the factor for limiting many industries, food production institute
The nutritional cost needed will be further increased, and high quality water product demand will be dramatically increased in country in Southeast Asia, and fishery will
Status or on a declining curve is kept, aquaculture product will account for staple market.Agricultural, especially culture fishery water cost simultaneously
Increase, environmental pressure increases.The ultimate challenge of 21 century agricultural production is to produce 3 times or more of production using less resource
Product.World Bank's whole world fishery plan-the year two thousand thirty fishery project tentatively proposes: 10-15 world aquaculture amount is necessary from now on
Increase by 100%, to meet the needs of people are growing to aquatic products.
Pond culture, reservoir cultivation and river cage culture are the traditional aquaculture mode in China always, but net cage
Cultivation is generally adapted the waters of the wide depth of water in river face, and pond culture yield per unit area is then much lower with respect to cage culture.Closely
Due to the pressure of national ecological, environmental protective over year, the net cage of many Tai Ho Roads is all removed, and traditional pond cultivation is also faced with
The requirements such as land status change is difficult, tail water qualified discharge is tight, cultured output room for promotion is smaller, restricts China to a certain extent
The further development of culture fishery.
In order to improve cultured output, people use pond inner recirculation flow water cultural technique.The cultivation of pond inner recirculation flow water
" the open free-ranging " of traditional pond is become " collection by Integration ofTechnology circulation flowing water fish cultural technique and ordinary pond fish cultural technique
Reduction stable breeding " makes " hydrostatic " pond realize " flowing water " and breeds fish.By the cultivation water for building water flow intercommunication in both ends in pond side
Slot number item (an installation oxygen increasing equipment pushes away water and makes stream, and an installation soil pick-up equipment extracts the wastes such as residual bait fish excrement), entire
Annular water flow is formed in big pond, concentration nursing can be carried out to fish in " runway " sink and will be drained using water flow
Object is focused in a slot and is uniformly processed.
It has been investigated that pond inner recirculation flow water mainly has at 3 points the shortcomings that cultivation: first is that daily running cost is high, pond
Inner recirculation flow water breeds fish to rely primarily on and powerful push away water oxygen increasing equipment continuous running and come for high-density breeding in sink
Fish provide sufficient oxygen and manufacture pond annular water flow, and daily power consumption is bigger, and running cost is high；Pond inner recirculation flow water
Aquacultural machinery equipment is more, and replacement easy to damage of paddling needs periodic maintenance to repair, and goes back especially for preventing accident power-off from stalling
Will be with emergency generation system and spare oxygen increasing equipment be packaged, this undoubtedly increases the manpower and material resources cost of operation.Second is that " runway "
Sink soil pick-up effect is poor, although one section of sink of the cultivation of pond inner recirculation flow water is provided with the wastes settling zones such as residual bait fish excrement,
Soil pick-up is extracted using equipment, but since the residual bait fish excrement in water with water body flow is often in suspended state, equipment is in water only
Fraction dirt can be extracted, and if meet dead fish fish body, equipment takes out dirty pipeline it is also possible to blocking.Third is that occupy
Water surface area is big, and the area of pond inner recirculation flow water cultivation is usually no more than the 20% of the pond gross area, remaining pond water surface needs
It is mating to be used to plant water purification plant treatment cultivation water, it is otherwise unable to satisfy pond runway and breeds fish water body requirement.
Therefore, it is necessary to develop one kind not only to have can be reduced investment, but also cultured output can be improved, increase the new of economic benefit and breed fish
System.
