Therefore, it can be said that the technical solution disclosed in the present invention has many advantages, and is particularly suitable for popularization and application in the field, and its market prospect is very broad.

Description of drawings

Fig. 1 is a schematic structural diagram of a sampling device according to an embodiment of the present invention.

Detailed ways

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Fig. 1: a kind of macroalgae attached biological sampling device, it comprises two mutually hinged semicircular steel rings 1, these two semicircular steel rings 1 can form a perfect circle, in the semicircular steel ring 1 is connected with a net garment part 2, and the net garment part 2 includes a net garment 3 directly connected with the semicircular steel ring 1, and this net garment 5 is cylindrical; the bottom end of the net garment 3 is connected with the lower net garment 4, and the lower Net clothing 4 is conical shape; The bottom of lower net clothing 4 is connected with impermeable sample collection bag 5, and sample collection bag 5 is cylindrical, and the diameter of sample collection bag 5 is less than the diameter of upper clothing 3, simultaneously in sample collection. The bottom end of the bag 5 is also provided with a valve 6 .

A method for sampling macroalgae adherent organisms by using the above-mentioned sampling device, firstly enter the water with two semicircular steel rings 1 close together, open the semicircular steel ring 1 of the sampling device, and collect the samples from the macroalgae Put it in the netting part 2 from the top towards the root, cut off the roots of the macroalgae and close the semicircular steel ring 1 again, bring the complete macroalgae back to the ship, and during the whole sampling process (i.e. the sampling device From launching to collecting macroalgae on board), video recording must be carried out.

Then the net part 2 of the sampling device is shaken in seawater, so that the organisms attached to the inner wall of the upper net 3 and the lower net 4 are concentrated into the sample collection bag 5, and then the macroalgae are put into a container filled with distilled water from the sampling device. The purpose is to wash off the organisms attached to the macroalgae. After scrubbing, the macroalgae are put into a sealed bag and recorded on the label.

The net part 2 of the sampling device is placed in the clean container two, the water body in the clean container one is poured into the net part 2 through the opening formed by the semicircular steel ring 1, and the net part 2 is taken from the clean container two. Take it out, and open the valve 6, transfer the water body in the sample collection bag 5 to the sample bottle, and shake the netting part 2 in seawater again, so that the organisms remaining on the inner wall of the upper netting 3 and the lower netting 4 are concentrated into the sample collection bag 5, and transfer this part of organisms together with the water body into the same sample bottle, add 5% formaldehyde fixative solution to the sample bottle, and perform sample processing or species identification operations.
