Method for preserving and displaying large benthic animal specimens

Abstract

The invention discloses a method for preserving and displaying large benthic animal specimens, and relates to the technical field of specimens. The method comprises 1, preparing related materials formaking specimens, 2, by a threading needle, penetrating through the side face of the chest of a large benthic animal body, then binding to the center of a glass slide, placing the specimen under an anatomical lens for posture correction, then slowly and obliquely placing the specimen after posture correction into a specimen bottle containing a stationary liquid by using tweezers, covering a bottlecap, cutting a sealing film with a proper length, sequentially stretching and winding for two circles along a bottle opening of the specimen, and sealing from the center of the bottle cap of the specimen, and 3, reserving 1-3cm blank parts above the sample labels containing species names, distribution, makers and other information, fixing the labels at the bottom ends of the sample bottles by using double faced adhesive tapes, and then respectively placing the specimens according to different class groups. The operation is simpler and more convenient, the long-term sealing performance is better, the aquatic organism diversity protection propaganda and education can be conveniently carried out, and the practicability is very high.

Description

technical field [0001] The invention belongs to the technical field of specimens, and in particular relates to a method for preserving and displaying macrobenthos specimens. Background technique [0002] Macrobenthos refer to invertebrates that live at the bottom of the water body, on aquatic plants or on rocks in the water for all or most of their life history and cannot pass through the 40-mesh sieve. Different macrobenthic groups have different sensitivity to water bodies, so the water quality can be judged according to the collected samples. In the monitoring and evaluation of aquatic environment organisms, macrobenthos are a must-test item for the monitoring of aquatic organisms in rivers and reservoirs. The production and long-term preservation of complete specimens of macrobenthos can vividly and intuitively reflect the succession of community structure, and then reflect Trends in water quality. [0003] Currently, macrobenthic specimens can be produced by needle in...

Problems solved by technology

[0008] In order to solve the poor sealing performance, poor display effect and poor aesthetic performance of existing specimens, they cannot be used to carry out publicity and education on aquatic biodiversity protection to the public. They need to be taken out and put back repeatedly, and the specimens are easily damaged, which affects the training effect problem; the purpose of the present invention is to provide a method for preserving and displaying macrobenthic specimens
