Problems solved by technology

While the interactive steady-state food web structure may only exist in shallow lakes, but the nutrient input has been kept high, to repeat the disturbance;
[0036] In the past, biological manipulation was carried out around closed enclosures, but now many studies have turned to manipulation experiments on the whole lake; the average success rate of biological manipulation is 60%, while the success rate of biological manipulation in the whole lake is only 15%, which shows that there is no information about the biological manipulation of the whole lake. Where research is clear (Mehner et al, 2002)

Embodiment 1

[0081] Artificial release of fish populations, closed cage culture of silver carp and bighead carp, three measures to establish natural fish populations by introducing water sources from Qingcaosha Reservoir, rebuilding the fish community structure of Qingcaosha Reservoir Demonstration Base from three aspects, in order to build an ecological A good community ecosystem can realize real water conservation fishery. Collect relevant fish regularly to measure the main biological parameters, mainly to understand the composition and growth of the community.

[0082] Among them, the types and weights of artificially placed resources are as follows, snail: 100 catties, regular size; river clam: 40 catties, regular size; river clam: 50 catties, small and medium size; Fish: 20 tails (25-30cm); mandarin fish: 20 tails (25-30cm), green shrimp: 20 catties (adult); silver carp (10) (about 250g);

[0083] The natural community is built. The pond of the demonstration base has been introduced i...

Abstract

The invention relates to a combined biomanipulation method for water-area ecological restoration. The combined biomanipulation method includes the steps that growth of phytoplankton in a system serves as starting; zooplankton is transplanted to the water body, and algae in the water body are controlled; aquatic vegetation is planted; after aquatic plants successfully grow, freshwater shrimps, caridina, small fishes, small carnivorous fishes, large carnivorous fishes and molluscs start to be put. By means of the combined biomanipulation method, all the key technologies in biomanipulation are integrated, food chains in the water-area ecological system are entirely and systematically rebuilt, the complexity of biocenosises is prolonged and improved, the stability of the system is improved, and the fixing function and the nutriment circulation function of the system are achieved.

Description

technical field [0001] The invention belongs to the technical field of water area ecological restoration and water purification fishery, and in particular relates to a composite biological manipulation method for water area ecological restoration. Background technique [0002] China's water ecosystems present varying degrees of eutrophication, and major lakes, such as Taihu Lake, Chaohu Lake, and Dianchi Lake, all present severe eutrophication. The water pollution incident in Taihu Lake in Wuxi affected the water supply of citizens, and Yancheng City was shut down for several days due to the pollution of urban water supply. How to carry out the ecological restoration of these water bodies? In the case of such serious non-point source pollution in China, how to control internal and external source pollution and reduce the occurrence of blue-green algae. For this reason, a variety of ecological restoration technologies have emerged in China. Similar large-scale ecological re...
