Technical field
The utility model belongs to Aquatic Toxicity Test device technique field, more specifically relate to a kind of spacer assembly avoiding individual cannibalism in small-sized shrimp, crab toxicity test, for the isolation of tested shrimp, crab, comparatively be applicable to the toxicity test of small-sized shrimp, crab class, comprise acute, sub-chronic and chronic toxicity test.
Background technology
Water body is the ground, an important home to return to after chemicals entered environment, entering the chemicals after water body to have an impact to aquatic ecosystem and hydrobiont wherein, is therefore the environmental benefit important role of toxicity test at evaluating chemical product of study subject with hydrobiont; In this external aquaculture, the application of agricultural chemicals and fishing medicine also has to pass through the inspection of toxicity test.The object of toxicity test is the harmless exposure level, pathotype, target organ, dose-response relationship etc. of determining chemicals, for chemical producting safety evaluation or hazard assessment provide data information.
Small-sized shrimp, crab class are the important component parts of aquatic ecosystem, and some kinds (as Procambius clarkii, Eriocheir sinensis etc.) wherein are also important cultivation objects.The pure animal fighting by natures such as many shrimps, crab class, have the habit of cannibalism, are especially in the individuality of shell phase more easily by cannibalism.When carrying out toxicity test, the death that cannibalism causes often causes larger impact to test.
Utility model content
The utility model provides a kind of spacer assembly avoiding individual cannibalism in small-sized shrimp, crab toxicity test, this apparatus structure is simple, make simple and easy, with low cost, easy to use, relatively can isolate tested small-sized shrimp, crab is individual, avoid the cannibalism between individuality, simultaneously little perforation also ensure that the exchange of experimental liquid and wherein material, and the opaque of baffle plate it also avoid the impact of individual test subjects visual effect on test, thus ensures accuracy and the reliability of toxicity test.
The utility model solves the technical scheme that its technical matters adopts: one can avoid small-sized shrimp, the spacer assembly of individual cannibalism in crab toxicity test, it comprises rectangle sample receiver, also comprise the length with square test container, wide, high corresponding short plastic dam and long plastic dam, the center position on the described long limit of short plastic dam has draw-in groove A, there is many clamp bar slots B on the long limit of long baffle plate, by chimeric for the draw-in groove A of short for polylith plastic dam and the draw-in groove B of long plastic dam, clamping, and live the gap between draw-in groove with finishing glue hydropexis, the both sides of the draw-in groove A of described short plastic dam are processed with multiple through holes, multiple through hole is processed with bottom the interval of the draw-in groove B of described long plastic dam.
Described short plastic dam and long plastic dam all adopt opaque vinyon to make, and thickness is 3mm.
Wide, high equal respectively with square test container of the length and width of described short plastic dam, the length and width of long plastic dam respectively with the length of square test container, high equal.
Described draw-in groove A is all positioned at the center position on 4 pieces of long limits of short plastic dam, and 4 clamp bar slot B lay respectively at 1/5,2/5,3/5,4/5 position on the long limit of long plastic dam, and draw-in groove A, draw-in groove B length are 1/2 of short plastic dam width, and width is 3mm.
Described through-hole diameter is 1mm.
Described draw-in groove A angle that is chimeric with draw-in groove B, that clamp is 90 °.
Draw-in groove A two side through hole of described short plastic dam is that 4 row 10 arrange.
Through hole bottom the interval of the draw-in groove B of described long plastic dam is that 5 row 10 arrange.
As shown from the above technical solution, in the method, the length of the square container that the short plastic dam of spacer assembly is used with long plastic dam and toxicity test is corresponding, spacer assembly is for isolating the individual test subjects of toxicity test, draw-in groove A and draw-in groove B by vertically fitting, clamp internal tank is divided into 10 mutually equity greatly, independently minizone, thus serve the effect avoiding individual test subjects cannibalism.The movement of plastic dam when being to make to avoid to test with the finishing glue hydropexis gap lived between draw-in groove, through hole is used for the exchange of experimental liquid between minizone and wherein material.Plastic dam adopts transparent materials to be in order to avoid individual test subjects visual effect is on the impact of test.
Advantage of the present utility model and beneficial effect are:
1, this apparatus structure is simple, manufactures simple and easy, manufactures this device raw material used very common and with low cost, thus cheap for manufacturing cost.
2, this device is easy to use, only this device need be put into the minizone that container can be divided into ten grades large, relatively independent by specification corresponding square test container easily when carrying out toxicity test, every tail individual test subjects occupies a minizone, avoid cannibalism, improve accuracy and the reliability of test; Take out after off-test.
3, experimental liquid and material wherein exchange by through hole, circulate; And through hole is all in the first half of baffle plate after assembling, individual test subjects is how movable in bottom, and the individuality between neighbor cell produces contact by little perforation hardly.
4, baffle plate material is opaque, avoids the impact of individual test subjects visual effect on test.
