Embodiment 1

[0024] The anesthesia method of cherry trout mainly comprises the following steps in the present embodiment:

[0025] 1) The anesthesia container and the recovery container use HDPE plastic boxes with a volume of 150L, ​​add 60L of breeding water in the breeding system to the anesthesia box 1 and the recovery box, and equip each of the anesthesia box and the recovery box with a thermometer. When the water temperature is higher than the breeding water temperature, add ice packs to cool down in time, and equip the anesthesia box and the recovery box with 1 100w air pump and 6-8 air stones for aeration and oxygenation to ensure that the dissolved oxygen content in the water is above 90%;

[0026] 2), add anesthetic tricaine to the breeding water of anesthesia box 1, stir and mix, the anesthetic concentration of anesthesia box 1 is 100ppm;

[0027] 3) Take 20 cherry trout with an average weight of about 200g, fish them into the anesthesia box 1 respectively, and cover the opening ...

Embodiment 2

[0031] Change the anesthetic agent concentration into "150ppm" in step 2) of embodiment 1, and other conditions are the same as embodiment 1.

Embodiment 3

[0033] Change the anesthetic concentration to "200ppm" in step 2) of Example 1, and other conditions are the same as in Example 1.

Abstract

The invention discloses an oncorhynchus masou narcosis method. Firstly water for breeding in a breeding system is added into two narcosis containers and a recovery container, anesthetic tricaine is added into the two narcosis containers, and then oncorhynchus masou to be subjected to narcosis is put into the narcosis container I for primary narcosis; the oncorhynchus masou obtained after primary narcosis is put into the narcosis container II for deep narcosis; then the oncorhynchus masou in the deep narcosis state is placed on an operation able for water-leaving operation; finally, the oncorhynchus masou obtained after water-leaving operation is put into the recovery container for recovery, and the oncorhynchus masou is placed back into the breeding system after being completely recovered. Two narcosis procedures adopting different containers and different anesthetic concentrations are conducted for primary narcosis and deep narcosis of the oncorhynchus masou, conditions of anesthetic concentrations, narcosis time and the like are optimized, the situations that the oncorhynchus masou revives too early due to insufficient narcosis and the oncorhynchus masou dies due to excessive narcosis in the operation process can be effectively avoided, and harm to the oncorhynchus masou in the water-leaving operation process is reduced.

Description

technical field [0001] The invention relates to an anesthesia method for cultured fish, in particular to an anesthesia method for cherry trout. Background technique [0002] Sakura trout, also known as Masu Daha and Mountain Girl Trout, has a Latin name of Oncorhynchus masou, belongs to the family Salmonidae, and belongs to the genus Oncorhynchus. It is a rare and economical cold-water fish, and its resources have declined sharply in recent years on the verge of exhaustion. Cherry trout is the fish with the largest ecological population and the most complex ecological morphological phenomena among dozens of species of salmonids. It is a species that is more likely to produce intergeneric and interspecific heterosis, and it is also a freshwater land-sealed river with the lowest latitude of natural distribution in the Asian continent. It has important biological, biogeographical and germplasm resources value. Since the 1990s, our country has introduced the eyes of cherry tro...
