A kind of holothruian cultures young participation Ciona separator
Technical field
The invention belongs to holothruian cultures field, be applicable to the separation of the young participation Ciona of holothruian cultures.
Background technology
Along with the fast development of holothruian cultures industry, harmful organisms Prevention Technique is relatively lagged behind, lack in addition and prevent consciousness, make this difficult problem have the gesture year after year increased the weight of, cause serious economic loss.From sea cucumber harmful organisms investigation result, Ciona is the important harmful organisms in holothruian cultures process, with the most difficult removing of Ciona in sea cucumber harmful organisms, when it occurs in a large number, can and sea cucumber fight for living space in breading sea cucumber seedlings system and bait, consumption dissolved oxygen, produce ammonia nitrogen, having serious inhibitory action to the growth of sea cucumber, also effectively do not control the method for the large generation of Ciona population at present, is a great problem of puzzlement holothruian cultures.Because its living environment is identical with sea cucumber, and easily make water body environment worsen, sea cucumber is easily caused " to arrange dirty " even dead, in culturing marine products field, Ciona is cultivated in later stage culturing pool in young ginseng generation more, at indoor raising of seedling, long-term pond of not falling, Ciona is easily made to grow on pool wall or adherance, at present, because Ciona biologically with sea cucumber the spitting image of, the medicine killing Ciona also can affect the growth and reproduction of sea cucumber, so there is no the method that Ciona removed by effective medicine, if have Ascidian to adhere in discovery cultivating system, as necessary by artificial removing.So not only waste a large amount of manpowers and material resources, and artificial sweep-out method is manually pick up to remove mostly, process is slowly complicated, easily causes the mechanical damage of dried up overlong time and sea cucumber epidermis in sea cucumber exposure air, very large to sea cucumber injury.
Summary of the invention
The problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of holothruian cultures young participation Ciona separator is provided, with Ciona, simple and quick being separated is carried out to sea cucumber, thus screen out Ciona, avoid using any medicine, damage can not be caused to sea cucumber, there is environmental protection and energy-conservation effect.
In order to achieve the above object, the invention provides a kind of holothruian cultures young participation Ciona separator, comprise the defiber be fixed on bracing frame of equidistantly arranging, the ratio that the spacing of adjacent described defiber is long with young ginseng average body to be separated is 1:1.1 ~ 1.3.
In addition, described defiber 2 selects nylon wire or wire; Under preferred embodiment, for long 1 ~ 5 centimetre of young ginseng of body, described defiber diameter 1 millimeter; For long less than the 1 centimetre young ginseng of body, described defiber diameter 0.2 millimeter.The diameter of described defiber can be selected according to the situation test of young ginseng to be separated.
In addition, under a kind of preferred embodiment, support frame as described above is that semicircular arc-shaped or bow and arrow type are arranged, and described defiber symmetry is tightened on support frame as described above.Under optimum way, described semicircular arc-shaped or bow and arrow type bracing frame openings of sizes are set to 40-45 centimetre.
Compared with prior art, tool of the present invention has the following advantages: 1, time saving and energy saving, and a people can operate in the short time, and good separating effect, screens out rate high, and through test, Ciona of the present invention screens out rate can reach more than 95%;
2, do not throw in any chemicals in separation process, can not cause outside mechanical damage to sea cucumber, in sea cucumber body, there will not be any medicament residue, greatly improve the quality of product;
3, environment friendly and pollution-free, really reach energy-saving and emission-reduction, the object of low-carbon environment-friendly;
4, a large amount of manpower and materials can be saved, while greatly saving production cost, contribute to the growth of sea cucumber, improve productive profit.
Accompanying drawing explanation
Fig. 1 is the theory structure schematic diagram of separator of the present invention.
Embodiment
As shown in Figure 1, the device of a kind of easy young participation Ciona quick separating of the present invention, comprise defiber 2, two ends are fixed on defiber bracing frame 1, and defiber 2 is uniformly distributed on bracing frame 1.Defiber spacing will arrange different spacing according to young ginseng growth size.Defiber diameter will arrange different size according to young ginseng growth size.Defiber bracing frame is the defiber fixture of semicircular arc-shaped or bow and arrow type, and defiber is superfine nylon wire or very fine wires, and defiber is distributed on defiber bracing frame with different distance according to different size.
Separator can for the young ginseng of long 0.5 ~ 5 centimetre of body, and young ginseng body is long is about 1:1.1 ~ 1.3 with defiber gap ratio.Defiber 2 selects nylon wire or wire.Defiber diameter about 1 millimeter is applied to long 1 ~ 5 centimetre of young ginseng of body, and defiber diameter about 0.2 millimeter is applied to long less than the 1 centimetre young ginseng of body.
Conveniently operate, increase stability, semicircular arc-shaped or bow and arrow type bracing frame openings of sizes are set to 40-45 centimetre, and handled easily increases device stability simultaneously.
During use, put into large basin together add water falling the young participation Ciona mixture behind pond, slide to the other end with young participation Ciona quick disconnector from basin bottom part one end, mention separator, sea cucumber on separator is transferred to the clean empty basin of another one, so repeatedly.Many for artificial sweep-out method people can be picked up the time shorten ten times removed.Reach time saving and energy saving efficiency high, there is good use value.
The present invention designs rationally succinct, greatly strengthen the stable of device and carrying effect, simultaneously can according to the adjustment of defiber diameter and defiber spacing and defiber bracing frame openings of sizes, reach the effect of the young participation Ciona of quick separating sea cucumber, structure is simple, the stronger time saving and energy saving efficiency of practicality is high, has good use value.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
