Abstract

The invention discloses a zooplankton living sample automatic sorting device. The device comprises a box body and a plurality of layers of ladder-like division otter boards which are arranged in the box body, wherein a zooplankton division part is enclosed by each ladder-like division otter board and the box body, and a plurality of mesh holes are formed in the portion, towards in direction of the center axis of the box body, of the bottom of each zooplankton division part; a swinging stirring rod is connected to the top of the box body, and a stirring ball is connected to the tail end of the swinging stirring rod; a zooplankton living body in each zooplankton division part is transported outside through an output pipe and a switch valve respectively; a cover body which can extend and retract in the vertical direction is inserted in each ladder-like division otter board close to the center of the box body, and a shading structure is arranged on the portion, close to the bottom or the top, of the cover body which can extend and retract in the vertical direction. The zooplankton living sample automatic sorting device is convenient to use, high in sorting efficiency, and the sorting effect is good.

Description

technical field [0001] The invention relates to the technical field of a sorting device for living samples of zooplankton, in particular to an automatic sorting device for living samples of zooplankton. Background technique [0002] Zooplankton are small animals that float or swim poorly in a body of water. There are many types of zooplankton, from low-level tiny protozoans, coelenterates, ctenophores, rotifers, crustaceans, gastropods, etc., to high-level urochordates, almost every type has permanent representatives Among them, copepods with various types, large numbers and wide distribution are the most prominent. The distribution of zooplankton in the water layer is also wide, whether it is in fresh water or in the shallow and deep layers of sea water, there are typical representatives. Zooplankton is the natural bait for the larval stage of aquatic animals, and some aquatic animals even use zooplankton as bait for their entire lives. Therefore, the artificial cultivat...
