Abstract
The utility model discloses a larval-young fish otolith dissection tool which is characterized by comprising a handle and a ladle-shaped structure positioned at the head of the handle. When collecting larval-young fish otolithes, the larval-young fish otolith dissection tool is matched with a dissecting needle to use so as to conveniently peel a colloidal biomembrane and completely find out the six integral otolithes of larval-young fish.
Description
Technical field
The utility model relates to a kind of dissecting tool, especially young juvenile fish otolith dissecting tool.
Background technology
The fish otolith is the functional lithosomic body that is present in the bony fish inner ear, mainly constitutes by lime carbonate, organic matter and a small amount of trace element, and be a kind of typical natural biological mineral.Total little otolith, star otolith, sagitta are respectively 1 pair in the inner ear of fish.The almost whole life process of fish is followed in the growth of fish otolith, the concurrent tangible record fish self-sow and the growth ring at age of giving birth to.Researching fish otolith microstructure features and ecological mechanism thereof; With the research of aspects such as the age that promotes its early stage stage history of life, growth, mortality ratio, magnitude of recruitment, population identification, swim the dynamic change etc. of habit, early stage dead factor and natural resources amount new method is provided for inquiring into its breeding, hole.Inquire into the influence of envirment factor to otolith growth ring deposition rule; The effect of research temperature method and chemical method mark otolith; Set up the method for the early stage fry of extensive mark; To be improve the survival rate of mark fry, and follow the tracks of the hole trip distribution habit after releasing, and release cultivation effect etc. of scientific evaluation is researched and proposed new thinking.In the collection of adult fish otolith, have ripe acquisition method at present; But in the collection of young juvenile fish otolith; More pressed-disc techniques that adopt more, there is following shortcoming in this technology: the first, because of the fish otolith mainly is that lime carbonate, organic matter and a small amount of trace element constitute; Therefore, easily otolith is crushed if strength control is improper during compressing tablet; The second, pressed-disc technique can not be peeled off the gluey biological membrane of the one deck above the fish otolith, and when examining under a microscope like this, biological membrane can exert an influence to observing sharpness and accuracy.The 3rd, six otoliths finding out young juvenile fish that pressed-disc technique can not be complete.And if the otolith that adult fish otolith acquisition method is used in young juvenile fish is gathered because young juvenile fish individuality is less, utilizes common dissecting tool to dissect young juvenile fish operation and be difficult for, destroy the interior ear structure of young juvenile fish easily, be unfavorable for the searching of otolith.Simultaneously the otolith of young juvenile fish is less and transparency is high, is not easy to find, general dissecting tool breaks up otolith again easily when gathering otolith.
Summary of the invention
The utility model purpose provides a kind of young juvenile fish otolith dissecting tool to the defective of prior art.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of young juvenile fish otolith dissecting tool is characterized in that: comprise handle and the spoon shape structure that is positioned at the handle head.
The utility model cooperates dissecting needle to use simultaneously when gathering young juvenile fish otolith, can peel off gluey biological membrane easily, intactly finds out six otoliths of young juvenile fish.

Fig. 1 is the utility model synoptic diagram;
1, handle; 2, spoon shape structure.
Embodiment
A kind of young juvenile fish otolith dissecting tool as shown in Figure 1 comprises handle 1 and the spoon shape structure 2 that is positioned at the handle head.
Claims (1)
1. a young juvenile fish otolith dissecting tool is characterized in that: comprise handle and the spoon shape structure that is positioned at the handle head.
