Abstract
The invention discloses a device for counting zooplankter. The device comprises a counting frame and a sieve arranged at the bottom of the counting frame, wherein an inner counting cavity of the counting frame is formed above the sieve; a plurality of equal-height partition boards dividing the inner counting cavity into multiple sub-cavities uniformly are arranged in the counting frame; the height of each partition board is smaller than that of the counting frame. When the device is used, sampled water is poured into the counting frame and is over the partition boards, the water and the zooplankter in the water are uniformly distributed in the sub-cavities, liquids in samples are filtered through the sieve, and zooplankter acquisition samples are obtained on the sieve. The inner side of the counting frame is uniformly divided into multiple sub-cavities, the number of the samples distributed in each sub-cavity is uniform in statistics in the sample concentration process, the number of the samples in a certain sub-cavity can be partially identified, all the samples can be evaluated, and the work efficiency is improved. The device integrates concentration and counting of the zooplankter samples and can prevent missing of large zooplankter.
Description
Technical field
The present invention, for zooplankter acquisition counter field, particularly relates to a kind of device of Planktont counting.
Background technology
Zooplankter is the secondary consumer in marine ecosystems, self be again the food of higher trophic level biology, in food web, play a part to form a connecting link swimming, its distribution characteristics and variation of quantity and secondary production force level all have material impact for structure function, resource output and the running of the ecosystem.
Group's composition and the abundance distribution of understanding zooplankter are the bases of its ecological functions of research, and zooplankter investigation is mainly the method for taking trawlnet sampling, takes back laboratory after fixed sample, carries out Identification of Species, sorting and counting under stereomicroscope. In net sample thief, conventionally comprising the zooplankter of different-grain diameter scope and some chip impurity, is mainly under stereomicroscope, to carry out sorting by being directly placed in after sample concentration to the processing of fixed sample at present. Zooplankter Identification of Species and the counting of carrying out mixed in together of different sizes, need to expend plenty of time and energy, and chip impurity is common and zooplankter adheres to each other, and is difficult to removing clean, has more increased the difficulty of qualification work.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly collect the concentrated of macroplankton sample and be counted as one, the device of the Planktont counting of increasing work efficiency.
The technical solution adopted for the present invention to solve the technical problems is: a kind of device of Planktont counting, comprise counting frame and the screen cloth that is located at described counting frame bottom, described counting frame forms counting inner chamber above screen cloth, in described counting frame, be provided with some contourly and counting inner chamber is evenly divided into the dividing plate in multiple points of chambeies, the height of each described dividing plate is less than the height of counting frame.
Be further used as the improvement of technical solution of the present invention, also comprise base, described base is provided with tank, and described sink top is uncovered, and described counting frame can be inserted in described tank.
Be further used as the improvement of technical solution of the present invention, described counting frame comprises top frame and the underframe that is located at described top frame bottom, and described top frame is fixedly connected with underframe and the edge of described screen cloth is clamped.
Be further used as the improvement of technical solution of the present invention, the two ends of each described dividing plate are connected with the inwall of counting frame, and the bottom of described dividing plate is smooth and prop up the end face of described screen cloth.
Be further used as the improvement of technical solution of the present invention, described screen cloth is drainage bolting silk.
Be further used as the improvement of technical solution of the present invention, the rounded or rectangle of described counting frame.
Be further used as the improvement of technical solution of the present invention, the tank on described base is circular trough or the rectangular channel of inserting for described counting frame.
Be further used as the improvement of technical solution of the present invention, the high 1.5cm of described counting frame, the high 0.5cm of dividing plate.
Beneficial effect of the present invention: when the present invention uses, the water body gathering by sampling bottle is poured in counting frame, the water body of sampling did not have dividing plate, zooplankter in water body and water body is uniformly distributed in each point of chamber, then fall the liquid in sample by the screen filtration of counting frame bottom, thereby obtain zooplankter collected specimens on the screen cloth in each point of chamber, counting frame of the present invention inside is evenly divided into multiple points of chambeies, in the sample size statistics distributing in each point of chamber in concentrating sample process, be uniformly distributed, can Partial Characterization the sample number in certain point of chamber wherein, carry out the assessment of whole sample, increase work efficiency. the present invention collects the concentrated of zooplankter sample and is counted as one, prevents that macrozooplankton from spilling simultaneously, when counting, counting frame can be placed in the container being filled with water, and completes the concentrated and counting of sample.
