The input size of said snakeheaded fish comprises: the snakeheaded fish of 0.1～0.4kg weight, preferred 0.25kg; Throw in density by wild fishes density decision in the water body,, generally, throw in density as a reference every mu of water surface 1-5 bar snakeheaded fish like water body for surface water V class water quality.
Said water body of treating to carry out the water ecology recovery project comprises: phytophage wild fishes excessive multiplication and endanger the water body of pasture and water growths.
Utilize snakeheaded fish to carry out the method that water ecology is repaired for above-mentioned; Also can comprise: the needs of repairing according to water ecology (promptly when wild fishes prey on by snakeheaded fish, under the situation of snakeheaded fish shortage food); The snakeheaded fish that individual in population is bigger shifts out water body, to regulate the snakeheaded fish density in the water ecology recovery project.The results dynamics of snakeheaded fish is promptly shifted out the snakeheaded fish quantity of water body, according to wild fishes residual density decision in the water body.
Said snakeheaded fish shifts out the method for water body, comprising: the method for fishing is caught with ground cage net.
The present invention introduces the water ecology recovery project with snakeheaded fish, through the method that this fish are put in employing in a suitable place to breed, controls the small-sized wild fishes in the restoration of the ecosystem system, to guarantee the pasture and water normal growth, to guarantee the water ecosystem balance and stability; And adopt the method that will unnecessary snakeheaded fish shifts out water body, soon part water eutrophication composition shifts out water body with the form of economy fish, thereby purifies water and realize the recycling of water eutrophication.Therefore, snakeheaded fish can be applicable to the water ecology recovery project.
Embodiment
The method of utilizing snakeheaded fish to carry out the water ecology reparation of the present invention; Mainly be that snakeheaded fish is rendered in the water body (threatening the water body of pasture and water growth like the wild fishes excessive multiplication) of treating to carry out the water ecology recovery project; Thereby carry out the water ecology reparation, concrete steps comprise:
(1) strain of snakeheaded fish is selected
Because snakeheaded fish is a kind of common predacious fish, the snakeheaded fish that is used in the water ecology recovery project needs the active healthy strain heavy, that tolerance is strong, and the best strain and the life history are more clearly, and other characteristics are selected according to requirement of engineering.In water landscape water ecology recovery project in Yuanmingyuan Park, Beijing, select Beijing strain for use, help adapting to Beijing winter climate, select simultaneously that individuality is big, decorative pattern is obvious, there is the fish of certain landscape value individual.
In addition; Like conditions permit, preferably need raise and train the snakeheaded fish that is used in the water ecology engineering, be about to its raise and train in the similar small water of engineering water quality hydrology climatic characteristic in; Fish unhealthy, injured to some during this time or the incompatibility request for utilization screens out; Satisfactory fish can be pulled out by engineering project and be invested in the engineering water body, and the flexibility that when throw in water body, preferably adopts purse seine or net cage to carry out for some time at engineering site is earlier cultured, during fish is observed screening.
(2) the input size of snakeheaded fish
Use the snakeheaded fish of water ecology recovery project to be preferably in about half jin.The fish of this size has that certain tolerance and appetite are big, growth rapidly, and cost is not high, convenient transportation.
(3) the input density of snakeheaded fish
Throw in density by wild fishes density decision in the water body, and according to the results dynamics of wild fishes residual density decision to this fish.For about half jin fish, the water body of surface water V class water quality is with reference to throwing in density at every mu of water surface 1-5 bar generally.
(4) results of snakeheaded fish (being that snakeheaded fish shifts out water body)
Generally speaking, snakeheaded fish no longer shifts out water body after throwing in.If cause the snakeheaded fish deprivation of food but wild fishes density is low, can the part snakeheaded fish be shifted out water body.Like the density of this fish of needs minimizing, select the bigger fish of individual in population to shift out as far as possible, thereby regulate the snakeheaded fish density in the water ecology recovery project;
