Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of sampling difficulties when sampling barnacles attached to rocks in the intertidal zone, easily breaking the barnacle shell and thus affecting the sampling effect, and provide a portable sampling device for The method of sampling attached organisms in the intertidal zone not only greatly facilitates the sampling of barnacles, but also ensures the integrity of the sampled barnacles

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] A kind of method utilizing portable sampling device to intertidal zone adherent organism sampling, comprises the steps:

[0029] a. Cover a piece of plastic film on the rock surface located in the intertidal zone, and make the edge of the plastic film seal and bond to the rock. At this time, an air gap is formed between the plastic film and the rock surface. It should be noted that the preferred size of the plastic film can be between 1m x 1m to 2m x 2m, so as to facilitate the laying of the plastic film, and the edge of the plastic film can be bonded to the rock through the corresponding adhesive, or it can be quickly dried Cement is laid at the junction of the edge of the plastic film and the rock. In addition, the plastic film is preferably an EVA heat-shrinkable film. Due to the rough surface of the plastic film made of EVA heat-sh...

Abstract

The invention discloses a method for sampling intertidal attaching organisms by means of a portable sampling device. The method comprises the steps of firstly covering the surface of an intertidal rock by a plastic film, binding the edge of the plastic film to the rock in a sealed manner, wherein an air gap is formed between the plastic film and the rock surface; connecting a vacuum device with anair outlet with a unidirectional valve on the plastic film, then starting the vacuum device for sucking air between the plastic film and the rock surface, hereon the plastic film clings to the rock surface; and when barnacles adhere on the surface of the plastic film, sleeving the barnacles to be sampled by means of a sampling sleeve, then forming vacuum in the sampling sleeve, thereby sucking the barnacles into the sampling sleeve. The method of the invention has advantages of greatly facilitating barnacle sampling and ensuring integrity of the sampled barnacle.

Description

technical field [0001] The invention relates to the technical field of biological research in the intertidal zone, in particular to a method for sampling the attached organisms in the intertidal zone by using a portable sampling device. Background technique [0002] With the rapid development of port construction, marine aquaculture, oil and gas exploitation, etc., the problem of marine fouling organisms has become more and more prominent, which seriously hinders the development and utilization of marine resources, forcing people to spend a lot of manpower Material resources to eliminate and control. Among the numerous marine fouling organisms, barnacles are a more representative one because of their ability to adapt to the environment. [0003] Barnacle is the most common marine fouling animal, and it is also the most important animal model in the testing and evaluation of antifouling performance of materials. The adult body of the barnacle has an extremely hard shell, an...
