Description
Technical field
The present invention relates to biological prevention and control field, relates to filter and the application of a kind of prevention and control Procambius clarkii particularly.
Background technology
Procambius clarkii (ProcambarusclarkiiGirard) is also known as lobster, cray, by Central America, South America, China is introduced as economic freshwater shrimps in Mexico northeast region, since the mid-90 in last century, the rapid rise of domestic cray industry, cray has become Important Economic breed variety in China.While like this, because of its omnivorousness, fast growth, adaptable and form absolute competitive advantage in local environment.Its scope of ingesting comprises pasture and water, algae, aquatic insect, spoil etc., food deficient scarce time also kill each other, grave danger is caused to ecotope, bio-diversity conservation.Therefore, no matter all should be strictly on guard against that it is escaped in the commercial aquaculture or prevention and control process of Procambius clarkii, be especially strictly on guard against and escape into unfrequented ecosystem water body, prevent it from local species ecologic competition advantage is caused to further destructive harm.
Traditional Procambius clarkii culturing pool and paddy field are only carried out stop with bamboo chip, iron or purse seine in discharge outlet and are escaped, but current common method only can stop passing through of adult shrimp in part water, often cannot prevent its young shrimp that climbing is crossed and individuality is less and fertilized egg flow downstream through.The present invention relates to filter and the application of a kind of prevention and control Procambius clarkii, effectively can prevent the escape of adult shrimp, young shrimp and fertilized egg, thus realize the prevention and control to the full lifestyle individuality of Procambius clarkii.
Summary of the invention
The object of this invention is to provide the filter of a kind of prevention and control Procambius clarkii, effectively can prevent the escape of adult shrimp, young shrimp and fertilized egg, thus realize the prevention and control to the full lifestyle individuality of Procambius clarkii.
Another object of the present invention is to provide the application of the filter of above-mentioned prevention and control Procambius clarkii.
Filter according to prevention and control Procambius clarkii of the present invention comprises:
Filter box body 1, described filter box body 1 is provided with coarse filtration grid 2, middle filter grid grid 3, fine filtering grid 4, gate 5 by hydrophilic side to hydrophobic side successively vertical bottom face, the bottom of described filter box body 1 is fixedly connected with tooth plate 6, and the bottom crown of described tooth plate 6 inserts ground downwards;
Wherein, the embedded multiple filter grid 7 of described coarse filtration grid 2, described filter grid 7 is narrowed to the inside gradually by hydrophilic side, for filtering Procambius clarkii adult shrimp and duckweed, rice straw, cultivation fish and stone etc.;
The embedded multiple filter grid 7 of described middle filter grid grid 3, described filter grid 7 is narrowed to the inside gradually by hydrophilic side, for filtering Procambius clarkii just from the young shrimp, fry etc. of close shrimp;
The embedded multiple filter grid 7 of described fine filtering grid 4, described filter grid 7 is narrowed to the inside gradually by hydrophilic side, is used for filtering at the beginning of Procambius clarkii incubating young shrimp and fertilized egg etc.;
Described gate 5 inserts in the aluminium groove track bar of described hydrophobic one end of filter box body 1, is close to described fine filtering grid 4, for closing and opening filter drain function.
According to the specific embodiment of the present invention, the described filter box body 1 of the filter of described prevention and control Procambius clarkii is the full aluminum material casing of cube of thickness 1cm, length of side 50cm, respectively there is with two ends and middle part equilateral aluminium groove track bar, and the wide coarse filtration grid 2 for 1cm, middle filter grid grid 3, fine filtering grid 4 can be allowed to insert and extract.
According to the specific embodiment of the present invention, described coarse filtration grid 2 is the full aluminum material flase floor of thickness 1cm, embedded 600 side length of sides are 2cm, the opposite side length of side is the three-dimensional square opening lattice of 1cm, all be greater than 3cm because Procambius clarkii adult shrimp body is long, described coarse filtration grid 2 can effectively stop that it passes through.
According to the specific embodiment of the present invention, described fine filtering grid 4 is the full aluminum material flase floor of thickness 1cm, embedded 600 side length of sides are 0.5cm, the opposite side length of side is the three-dimensional square opening lattice of 0.25cm, effectively can incubate young shrimp at the beginning of the long Procambius clarkii for the disengaging parent of 0.25-1.0cm of baffle element and fertilized egg is passed through, and make it to be exposed between middle filter grid grid 3 and fine filtering grid 4, be convenient to catch and kill.
According to the specific embodiment of the present invention, described gate 5 is the full aluminium panels of thickness 1cm.
The filter that invention also improves described prevention and control Procambius clarkii is in the application in Invasive Alien Species control, environmental monitoring and bio-diversity conservation field.
The filter of a kind of prevention and control Procambius clarkii of the present invention, it is applicable to Invasive Alien Species control, environmental monitoring and bio-diversity conservation research and science popularization teaching aid market, has wide market prospects.
Beneficial effect of the present invention is: it is different from traditional Procambius clarkii culturing pool and paddy field safeguard procedures, the filter of a kind of prevention and control Procambius clarkii of the present invention filters paddy field water either by utilizing the coarse filtration grid narrowed backward, culturing pool, the Procambius clarkii adult shrimp of the water body discharge outlet such as water channel and duckweed, rice straw, cultivation fish and stone etc., by middle filter grid filtration just from the young shrimp of close shrimp, by incubating young shrimp and fertilized egg at the beginning of fine filtering grid filtration, thus effectively prevent Procambius clarkii from becoming shrimp and ovum thereof, young shrimp diffuses to other water bodys from discharge outlet, realize the prevention and control to the full lifestyle individuality of Procambius clarkii.It is strong that the present invention has corrosion resistance, durable, and maintenance cost is low; the features such as control effect is good; there is very high practicality and durability, be applied to Strategy of Alien Invasive Species prevention and control, Bioindicator monitoring, bio-diversity conservation research and science popularization teaching aid market, there are wide market prospects.
