Embodiment Construction

[0020] This specific embodiment adopts following technical scheme: its method is as follows:

[0021] Step 1: Prepare relevant materials for making specimens:

[0022] Materials include complete macrobenthos individuals, specimen bottles (specimen bottles with different inner diameters are prepared according to the size of macrobenthos individuals, such as 45mm (inner diameter) × 60mm (height), 45mm × 90mm, 60mm × 90mm and other models), 75% alcohol or 4% formalin fixative, needle and thread with a diameter of 1mm, glass slides (slides of different lengths and widths are prepared according to the individual size of macrobenthos, such as 40mm (length) × 25mm (width) ), 70mm×25mm, 70mm×40mm and other different specifications), parafilm, label, dissecting mirror, dissecting needle.

[0023] Step 2: Use a threaded needle to run through the side of the chest of the macrobenthic animal and tie it to the center of the glass slide, put it under the dissecting microscope to adjust the...

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...
