Problems solved by technology

However, the traditional anesthesia method with water is not ideal for loach. Practice shows that it is difficult for loach to achieve anesthesia effect under the condition of water anesthesia. The main reason should be that loach has intestinal respiratory function. It is difficult to enter the body of loach through the gills. To achieve anesthesia effect th...

Embodiment 1

[0017] Embodiment 1: The technical means realized by the present invention will be specifically described below in conjunction with examples.

[0018] A kind of method for efficient anesthesia of loach parent, its steps are:

[0019] A. On May 12, 5 kg of male and female loach parents were selected to prepare for artificial induced labor. Anesthesia was performed at 19:00 in the evening, and the parents were fished out, drained and placed in a prepared plastic basin to prepare for anesthesia.

[0020] B. Weigh 50mg of MS-222 with an analytical balance, dissolve it in 20ml of clear water, pour it into a plastic basin after the dissolution is completed, and immediately cover another plastic basin to prevent the parent loach from jumping out.

[0021] C. About 3 or 4 or 5 minutes, the parent loach completely stops jumping, and the anesthesia is completed. At this time, the parent loach exhibits opening and closing of the gill cover, swallowing air with its mouth open, and there ...

Embodiment 2

[0025] After enlarging the production scale, the applicant designed a fixed operating table, which is convenient for large-scale loach parental anesthesia, and the effect is good.

[0026] A kind of method for efficient anesthesia of loach parent, its steps are:

[0027] A The fixed operating table is an ordinary cement table with a height of 70-80cm, a length of 110-120cm, and a width of 60-80cm. Place a long 100cm on the table, wide 50cm, deep 30cm square plastic box, be used to place loach parent.

[0028] B selects 50kg loach parent, drains the water and places it in a plastic basin to prepare for anesthesia.

[0029] C Weigh 500mg of MS-222, dissolve it in 30ml of clear water for anesthesia, the anesthesia method is the same as in Example 1, the injection after anesthesia, parental treatment, etc. are all the same as in Example 1

[0030] DUsing a fixed operating table is convenient for large-scale and standardized production operations. The height of the operating tabl...

Abstract

The invention discloses a method for efficiently anesthetizing a loach parent. The method includes the steps that A, a selected loach parent is fished out, and is placed in a prepared plastic basin after being drained off; B, anesthetic is dissolved in clear water, and is poured into the plastic basin after being dissolved; C, the loach parent reacts fiercely, the upper portion of the plastic basin is covered with another plastic basin so as to prevent the loach parent from jumping out, and anesthesia is completed after 3-5 minutes; D, oxytocic begins to be injected, the loach parent is placed in clear water after injection is completed, and after reviving completely in 5-10 minutes, the loach parent is placed in spawning equipment for awaiting delivery; tricaine methanesulfonate is selected to serve as the anesthetic; the using dosage of the anesthetic is 10 mg/kg, and the anesthetic is dissolved in 10-30 ml of clear water in the using process. The method is easy to implement and simple and convenient to operate, the fast anesthetic effect is achieved through the skin permeation action, and therefore the spawning induction efficiency of loaches is improved obviously.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for efficient anesthesia of loach parents, which can also be used for anesthesia of other types of loach and paraloach. technical background [0002] Loach is one of the emerging breeding species in my country in recent years. The market demand is increasing year by year, and the breeding boom is very high. Loach is a small freshwater economic fish, which is mainly distributed in East Asia. It has high nutritional value and is known as water ginseng. . However, the seed of loach breeding industry in my country mainly comes from wild seed, which is mainly due to the high mortality rate in the process of large-scale cultivation of loach seed, while wild seed has the problems of being difficult to domesticate artificial feed and unstable survival rate. Therefore, the cultivation of artificial seedlings is crucial to the healthy development of the loach industry. The artificial r...
