Embodiment 1

[0026] (1) According to the stage of anesthesia and resuscitation behavior of golden squid, then determine the appropriate concentration of golden squid anesthesia operation and anesthesia transportation

[0027] Experimental design 2, 5, 8, 15, 20, 30, 40, 60 and 80mg / L9 concentration gradients, each concentration test 5 adult golden squid, determine the final anesthesia degree of golden squid within 24 hours, and observe the final anesthesia Then transfer to clean seawater for resuscitation, observe the behavioral characteristics during the resuscitation process, and then stage the degree of anesthesia and the resuscitation process.

[0028] Test results: 1) The degree of anesthesia was divided into six periods according to the behavioral characteristics in the final anesthesia state, see Table 1.

Embodiment 2

[0036] In June 2012, we transported 250 adult golden cuttlefish from Qingdao Jinshatan Aquaculture Development Co., Ltd. to Tianjin Xinyongfeng Aquaculture Co., Ltd. Cool the transport water with ice cubes from 24°C to 18°C, add 7mg / L of MS-222, and then fill it with pure oxygen to saturation with nano-air stones; add ice cubes or ice bottles to the golden squid breeding ponds that have stopped eating for 1 day to cool down, and after 2 The temperature difference should not exceed 3 °C each time, and the temperature was lowered to 18 °C; then MS-222 with a final concentration of 30 mg / L was added, and the golden squid entered the fourth stage of anesthesia after 5 minutes, that is, the wrists were spread out, and the sideways The fins stop swinging and the sense of balance is lost. Immediately fish the golden squid gently into the washbasin, weigh it, slowly fish it out by hand and put it into a black plastic bag with 10L of transport water, and put 1 adult golden squid in each...

Embodiment 3

[0038]In July 2012, we transported 150 adult golden squid from Huangdao golden squid experimental base of Yellow Sea Fisheries Research Institute to Xinhaixin Nursery Farm in Xiapu, Fujian. Cool the transport water to 16°C with ice cubes, add 8mg / L MS-222, and then fill it with pure oxygen to saturation with nano air stones; add ice cubes or ice bottles to the golden squid breeding ponds that have stopped eating for 1 day to cool down, and after 3 times gradually Step-by-step cooling treatment, the temperature difference does not exceed 5°C each time, and the temperature is lowered to 16°C; then MS-222 with a final concentration of 60 mg / L is added, and the golden squid enters the fourth stage of anesthesia after 3 minutes, that is, the wrists are spread out, and the side fins stop. Shake and lose the sense of balance. Immediately fish the golden squid gently into the washbasin, weigh it, slowly fish it out by hand and put it into a black plastic bag with 10L of transport water...

Abstract

The invention discloses a long-distance transportation method of sepia esculenta adults, and belongs to the field of aquatic product transportation. The long-distance transportation method comprises the steps of two-step oxygenation and two-step anesthetization, wherein the transportation time is not more than 20h; the two-step oxygenation comprises the following steps: oxygenating water for transporting sepia esculenta in a water reservoir with a nano-airstone until saturation, and oxygenating a transportation bag after the sepia esculenta adults are placed into the transportation bag; and the two-step anesthetization comprises the following steps: adding 30-60mg / L of MS-222 anesthetic to a sepia esculenta culture pond without disturbing the sepia esculenta adults, and instantly weighing and packing for transportation when the sepia esculenta adults are anesthetized until the sepia esculenta adults stop swinging the lateral fins and lose the sense of balance; and adding 5-8mg / L of MS-222 anesthetic to the water for transportation, so that the sepia esculenta adults maintain a two-stage anesthetic transportation state, namely, the sepia esculenta adults slightly lose the touch sense, fold the wrists, swing the fins naturally, and changes the body color slightly. With adoption of the long-distance transportation method of the sepia esculenta adults, the survival rate of the sepia esculenta adults during long-distance transportation is significantly increased, and the technical problem about the long-distance transportation of the sepia esculenta adults is solved.

Description

technical field [0001] The invention belongs to the field of aquatic product transportation, and in particular relates to a method for long-distance transportation of adult golden squid. Background technique [0002] Under natural conditions, when encountering danger, inkjet is a kind of escape behavior of cephalopods. The ink sprayed can turn the nearby seawater into black, thereby hiding itself and escaping with the rapid jet of water. In addition, ink also contains toxins, which also have a certain offensive effect on enemies. Also in the breeding process, it was found that cephalopods are also prone to inkjet behavior during brood acquisition, tank dumping operations, and individual fights, especially during long-distance transportation before bagging, weighing and transportation. for serious. The inkjet behavior of cephalopods during transportation not only damages the body, but also easily deteriorates the water quality, resulting in a low survival rate during transp...
