Description
Technical field
The present invention relates to a kind of fish and purify the inland eutrophication freshwater method of repairing, being specifically related to a kind of offshore river mouth marine fishes---grey mullet moves and grows the method for repairing water environment to inland eutrophic water, purification, is that algae control method and activity are repaired in the purification that is applicable to the inland eutrophication freshwater of lake, rivers, reservoir, landscape water body, wet land system feature.
Background technology
2006, in 408 surface water monitoring sections in 197 rivers of the large water system of China seven (containing river, national boundaries), the section ratio of IV～V class and bad V class water quality was respectively 28% and 26%.The Liaohe River, Huaihe River, the Yellow River, Song Hua River water quality are poor, and Haihe River is seriously polluted, and trunk river aquatic ecosystem health is subject to obvious impact.Lake and reservoir eutrophication problem is serious, forms the Water Environment In Lakes problem take nitrogen and phosphorus pollution as essential characteristic.In 27 state control emphasis lakes (storehouse), 5, the lake (storehouse) of V class water quality, accounts for 19%; 13, bad V class water quality lake (storehouse), accounts for 48%.Nearest investigation shows, the lake eutrophication of the Asian-Pacific area 54%, and the eutrophic lake ratio of Europe, Africa, North America and South America is respectively 53%, 28%, and 48% and 41%, China is 60%.Taihu Lake, Dian Chi and Chaohu are in moderate eutrophic state.Lake eutrophication will directly cause deteriorating water quality, hypofunction, and aquatic ecosystem is unbalance; Eutrophic improvement there is no so far a lake and realizes water quality and ecological recovery completely, and eutrophication is a non-reversible process.Lake eutrophication outstanding problem, blue-green alga bloom takes place frequently, and river type waterhead area potential safety hazard is many, and sudden water pollution event very easily occurs.In China, having 1/4 city tap-water factory is take lake or reservoir is water source, pollutes and eutrophication makes limited Freshwater resources deficienter, and drinking water safety is on the hazard, publilc health is threatened, and China's rural potable water water quality condition also allows of no optimist simultaneously.The centralized drinking water source environmental aspect investigation in the above city of region was shown in 2011 according to Environmental Protection Department, approximately 35.7 billion cubic meter source qualities are not up to standard, account for 11.4% of total supply.
Because transition is fished for, natural fisheries water fishing resources decline is serious, species diversity declines obviously, cause miniaturization of fish, cause fish species and quantity significantly to reduce, destroy aquatic food webs network system, form the accumulation of Eutrophication materials, progressively by exogenous pollution to the endogenous pollution evolution that surmounts waters detergent power, overfishing may form by food web stable, but the undesired new consumers and producers of people, the ability of the natural fisheries water nutritive substance of hydrocoles trans-utilization declines gradually, hydrocoles purifying treatment ability more and more can not meet the requirement of disposal of pollutants, economic construction makes a large amount of nitrogen, the natural fisheries water of the excessive input of the nutritive substances such as phosphorus, the accumulation of natural water area eutrophication is more and more serious, water quality deterioration, the public waters ecosystem is unbalance, in this case, change eutrophic state and need to recover habitat, repairing food chain or taking relatively fierce gimmick to reduce storage effect makes system get back to state before.China is renovating lake environment energetically in recent years, and the method that purifies reparation waters mainly contains Physical and biological process.Physical mainly comprises mechanical salvaging, Sediment Dredging, artificial aeration, and this method need expend more human and material resources and financial resources, is not suitable for water field of big area; Biological process is rationally to adjust aquatic food chain, utilizes nutrition and Predatory relation, and interbiotic interaction, reaches and purifies the object of repairing waters.The advantages such as that biological process has is pollution-free, low consumption, sustainability, therefore receive increasing concern.
Conventionally carry out and comprise: sewage dams, ecological dredging, move back the comprehensive control measures of also also water, restoration of the ecosystem of lake, power of fishing, loke shore regulation and the construction of Huan Hu forest belt etc., be that ectogenic regulation and control improve Effects of Water Quality not remarkable; And use biological endogenous property means, and utilizing fish, shrimp, shellfish, algae is that main bioorganism carries out Ecological Recovery of Water, effect is more obvious.The measure of natural water area restoration of the ecosystem is mainly: (1) lakeside wetland treatment technology take hygrophyte as core: utilize vegetation buffer zone that pollutent is stopped, absorbed and transforms; Utilize artificial swamp make pollutent precipitation, degraded and absorbed by hydrobiont (being mainly microorganism).(2) to increase zooplankton as ecotechnology basis, that directly control algae.(3) to recover waterplant, the shallow waters ecological reestablishment of the training straw-planting type ecosystem.Above ecological reestablishment measure shows, aquatic higher animal does not obtain enough attention in aquatic ecosystem reparation, and the aquatic higher animal such as fish just in time can overcome the restriction of the water body depth, especially fish can be taken into account shoaling water and ballow, the ability of repairing in the performance of larger waters scope.Ignore the minimizing of fish value volume and range of product, fish food chain function weakens and lacks, and ignores the water purification repair of fish minimizing pollutent storage effect, and nearly ten years water bodys are repaired unsuccessful former therefore place just.Harness the river with fishing, repair and rebuild water ecosystem, recover water ecosystem structure, reduce lake endogenous pollution, realize Lake Water function and value of services, maintain and stablize healthy aquatic ecosystem, can reach exogenous means can not and object.Therefore, work out best fishery scale and the mode of production, development is the development path of a fishery and environmental protection doulbe-sides' victory by the water purification fishery of " centered by water ", guarantees the good ecotope in waters and fishery sustainable utilization.
In endogenous control algae and reparation water body method, microbial method promotes blue-green algae rot and be decomposed at natural water, but has ecological risk; Crustacean method cultivates, forms and maintain suitable population density difficulty at natural water area; Plant method is degraded to small-molecule substance and just can be absorbed and the fish method digestion blue-green algae that directly eats after organic corruption, before blue-green algae and organic corrupt degraded, is transformed and utilizes.Main biological restoration water body method is aquatic plant purification restorative procedure at present, especially Herba Eichhorniae stable breeding control algae recovery scenario is the competing method of this control algae recovery scenario, the major defect of this scheme is that the aquatic plant harvesting processing such as the Herba Eichhorniae growing up to every year expend a large amount of manpowers, the waterplant product resource difficult treatment such as the Herba Eichhorniae of harvesting, easily form new pollution, carry out ingoing river source of pollution and water pollution load reduction technology integrated with demonstration, carry out the blue-green alga bloom control of storehouse, lake and ecological reestablishment integrated with demonstration, progressively improve lake region quality of water environment.
In recent years clean environment engineering is carried out rapidly, and its core is take waterplant, filter feeder, Omnivore as clean biometric, and strengthening environment cleaning function reduces natural water area and the Pollutant levels of the water body of surviving.At public freshwater; take modern ecological theory as basis; according to the specific envrionment conditions of water body; by manually putting suitable fish species and quantity in a suitable place to breed; to improve the Fish Communities composition in this waters; ensure the eubiosis, thereby both reached protection water surrounding, can make full use of again the aquatic products power of water body.
In freshwater environment, purify the multi-functional fish kind shortage of repairing control algae, so far only has silver carp flathead, tilapia Ji the minority fish such as Xie Jaw silver xenocypris as the reports of freshwater control algae fish, grey mullet (Liza haematocheila), have another name called cute conjunctivitis mullet, large-scale offshore river mouth marine fishes, China coast all has distribution, many south, north is few, property is active, happiness is jumped, inhabit in river mouth and bay, and can enter fresh water, juvenile fish is liked cluster, there are obvious phototaxis and rheotaxis, the suitable salt scope of grey mullet is 0～38 ‰, can in the waters of 3 ℃～35 ℃ of water temperatures, live, optimum water temperature is 12 ℃～25 ℃.Grey mullet is individual large, growth potential and conversion water purification ability are remarkable, it can survive in fresh water environment, can only in seawater, breed, in bibliographical information, so far there are no purifies and repair the reports of fish as freshwater for seawater grey mullet, by grey mullet as purify the multi-functional fish of repairing control algae in lake, the method for the inland eutrophication freshwater novelty application of rivers, reservoir, pond, artificial swamp feature has no report.
Summary of the invention
