Problems solved by technology

At present, the traceability analysis methods of salmon include tail fin clipping method, T-ID labeling method, CWT line marking method, VIE fluorescence method and SSR microsatellite marking method; among them, the tail fin clipping marking method has only returned 3 fish in more than ten years. T-ID labeling method, CWT line labeling method, and VIE fluorescence method are more harmful to the fish body. SSR microsatellite labeling method can accurately evaluate the release effect of salmon through kinship identification, but the genetic information extraction of parents and offspring in this method consumes Sometimes it costs a lot of money, the professional threshold is high, and a large number of professional and technical personnel are needed to support it, which cannot meet the actual needs of long-term and periodic evaluation of salmon traceability

Embodiment 1

[0025] A method for marking salmon otoliths based on Morse code rules, the method comprising the following steps:

[0026] (1) Otolith markers are marked with the letter JL, and the Morse code code is: · — — — · — · ·. Wherein "·" is 24 hours, "—" is 48 hours, marked with high temperature; code interval is 24 hours, marked with low temperature. The marking pattern is: 24H-24C-48H-24C-48H-24C-48H-24C-24H-24C-48H-24C-24H-24C-24H, where H represents the high temperature period, C represents the low temperature period, Arabic numerals 24 and 48 represents the duration (in hours).

[0027] (2) The hatching process of salmon is running water hatching. Before the heat marking is implemented, observe the development of fertilized eggs and record the water temperature;

[0028] (3) When the fertilized egg develops to the eye stage, run the water temperature control equipment according to the implementation time of the heat-marked water temperature regulation cycle mode; the high temp...

Embodiment 2

[0037] A method for marking salmon otoliths based on Morse code rules, the method comprising the following steps:

[0038] 1. Otolith markers are marked with the letter CHN, and the Morse code code is: —·······························. Wherein "·" is 24 hours, "—" is 48 hours, marked with high temperature; code interval is 24 hours, marked with low temperature. The marking pattern is: 48H-24C-24H-24C-48H-24C-24H-24C-24H-24C-24H-24C-24H-24C-24H-24C-48H-24C-24H, where H represents the high temperature period and C Indicates the low temperature period, and the Arabic numerals 24 and 48 indicate the duration (in hours).

[0039] 2. The hatching process of salmon is running water hatching. Before the heat marking is implemented, observe the development of fertilized eggs and record the water temperature;

[0040] 3. When the fertilized egg develops to the stage of eye development, run the water temperature control equipment according to the implementation time of the heat-marked ...

Abstract

The invention provides a method for marking salmon otoliths based on the Morse code rules, which is characterized in that the method first sets the otolith marking map according to the Morse code rules, and then develops the otoliths from the fertilized eggs of the salmon During the incubation period, adjust the hatching water temperature so that the lightness and width of the otolithic sun wheel of the salmon are formed according to the requirements of the map. The present invention combines the international general Morse code rules, utilizes the influence of water temperature on the otolith wheel patterns to mark the released salmon, and provides a cannabis that is economical and practical, has a high marking rate, is not easy to be confused, and has a high recognizable rate. The labeling method of releasing salmon can carry out labeling of a large sample size, and at the same time avoid the harm caused by the use of chemicals to the fish body and the environment. The invention can more completely and accurately evaluate the release effect of salmon.

Description

technical field [0001] The invention belongs to the technical field of aquatic organisms, and in particular relates to a method for marking salmon otoliths based on Morse code rules. Background technique [0002] Salmon ( Oncorhynchus keta Walbaum ) belonging to the Salmoniformes ( Salmoniformes ), Salmonidae ( Salmonidae ), Pacific salmon, which is a famous cold-water anadromous spawning and migratory fish in the Tumen River Basin in Changbai Mountain, Jilin Province. In recent years, due to the deterioration of the living environment caused by human factors such as water conservancy projects, its resources have decreased sharply, and it is currently in an endangered state. It is reported that the genetic diversity of the salmon population in the Tumen River Basin is relatively rich, and its resources can be restored through artificial breeding. Artificial breeding and release has become the selected program for the protection of germplasm resources of salmon populati...
