Abstract
The present invention relates to a fish electronarcosis method, particularly to a method for the narcosis of fish living bodies. The present invention needs to solve the technical problems of the narcosis method that the narcosis of the fish is not rapid; after narcosis, side effects on the fish are great, and long-period influence on the fish is increased. The present invention has the technical scheme that a water tank needs to be prepared. The present invention is characterized in that both ends of the water tank are provided with metal net electrodes; the metal net electrodes which are respectively connected with a positive electrode and a negative electrode of a direct-current power source with adjustable electric currents and adjustable voltage on both of the two ends become electronarcosis tanks; the fish are placed into the electronarcosis tanks, and the electric currents are kept between 0.1 A and 0.2 A. According to the individual size and the different kinds of the fish, the voltage rotary knob is regulated at the point from 0 to 36V, and electric field intensity is from 0.4 to 0.5Vcm<-1>. After the power source is switched on, the narcosis is obtained within 10 seconds. The present invention is suitable for the narcosis operation of the fish living bodies in the process of scientific research and production practice.
Description
Technical field
The present invention relates to method that the fish live body is anaesthetized.
Background technology
In scientific research and production practices, be operated the injured of object, need anaesthetize fish for the ease of the fish live body being operated and being reduced.For a long time, the fish anaesthesia technology is to utilize MS-222, the drug anesthesia of cloves wet goods, the effect that nervous centralis and the peripheral nerve by the drug influence fish reaches anesthesia.It is long that drug anesthesia reaches time of anaesthetic effect, and fish are also longer by the time of recovering again again after anaesthetizing.Fish generally will just can reach holonarcosis through 5 reflex action stages, promptly calm stage of mild sedation stage, the degree of depth, part disequilibrium stage, fully the disequilibrium stage, lose the respond stage.Need 4～7 minutes as MS-222 anesthesia sturgeon, needed 6～10 minutes time to recover again to move about fully freely by postanesthetic sturgeon with 100mg/L.Because drug anesthesia is consuming time longer, and the physical signs that fish are anaesthetized in the body of back also can be affected, all can change as cortisol, glucose, lactate isoconcentration, eliminated in postanesthetic a period of time and can influence ingest normally by the fish that chemistry was anaesthetized, so that g and D is being produced long-term negative effect.
Though the method for once used electric shock fishing has anesthetic effect to fish in the halieutics, electric shock is fished and is not taken into account fish in The Long-term Effect aspect the anesthesia, can not use in scientific research and production practices.Therefore, need a kind of energy quick-anaesthesia fish, and the anesthesia back is little to the side effect of fish, fish is reduced to the method for floor level in The Long-term Effect aspect the anesthesia.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of quick-anaesthesia fish, and the anesthesia back is little to the fish side effect, reduces the anesthesia to the The Long-term Effect of fish.
Technical scheme of the present invention need be equipped with a tank, it is characterized in that the tank two ends are equipped with the wire netting electrode, and the wire netting electrode at two ends connected the both positive and negative polarity of the adjustable dc source of current/voltage respectively and become Electronarcosis tank, fish is put into Electronarcosis tank, electric current remains on 0.1～0.2A, by individual size and the variety classes of fish, setting up an office the voltage knob in 0～36V adjusting, electric-field intensity is 0.4～0.5Vcm
-1, fish reaches anesthesia in 10 seconds after connecting power supply.
The fish that the present invention will anaesthetize is put into tank, after connecting dc source, fish was anaesthetized in 10 seconds of direct current effect, and fish only just can reach anesthesia through part disequilibrium and complete two stages of disequilibrium, in 1 minute, can be recovered normal by the anesthesia fish, reach the quick-anaesthesia fish, save time, and have no side effect and the loud technique effect of the portrait or photograph of the deceased without issue.
Description of drawings
What accompanying drawing was represented is the schematic diagram of fish electronarcosis.
Embodiment
Implement best way of the present invention below in conjunction with description of drawings:
Technical scheme of the present invention need be equipped with a tank 1, according to being selected the tank of different size by the size of anesthesia fish, as flute length at 30cm～300cm; Groove width is at 15cm～60cm; Groove depth is at the tank of 10cm～60cm, a slice wire mesh electrode 2 is respectively arranged at tank 1 two ends, the fore-and-aft distance of two ends wire netting electrode 2 can be regulated by being a bit larger tham fish body 4 length, and the both positive and negative polarity that the wire netting electrode 2 at two ends connects the adjustable dc source of current/voltage 3 respectively promptly becomes the anesthesia groove that carries out fish electronarcosis; In the anesthesia groove, keep certain depth of water, to be put into the anesthesia groove by anesthesia fish 4, the fore-and-aft distance of regulating two ends wire netting electrode 2 is a bit larger tham fish body 4 length, with the current value adjustment of power supply near 0A, the voltage-regulation knob is set up an office about 5V, power-on is slowly heightened voltage to fish then and is anaesthetized in the scope that is no more than 36V voltage.For example anaesthetize that body is long to be the sturgeon of 30cm, with the head of fish positive pole towards electric field, power-on, electric current 0.1A, voltage transfers to 25～30V, and electric-field intensity is 0.4～0.5Vcm
-1, connect behind the power supply 10 second fish anaesthetized, remove electric current after, fish recovered normally to move about within 1 minute and has no side effect and back portrait or photograph of the deceased sound.
Claims (1)
1, fish electronarcosis method, need to be equipped with a tank, the tank two ends are equipped with electrode and are connected the both positive and negative polarity of the adjustable dc source of current/voltage respectively and become Electronarcosis tank, fish is put into Electronarcosis tank, the electrode that it is characterized in that the tank two ends adopts the wire netting electrode, electric current remains on 0.1～0.2A, and by individual size and the variety classes of fish, setting up an office the voltage knob in 0～36V adjusting, electric-field intensity is 0.4～0.5Vcm
-1, fish reaches anesthesia in 10 seconds after connecting power supply.
