Embodiment 1

[0026] (1) Stage according to the anesthesia and resuscitation behavior of golden squid, and then determine the appropriate anesthesia operation concentration and anesthesia transport concentration of golden squid

[0027] Experimental design 9 concentration gradients of 2, 5, 8, 15, 20, 30, 40, 60 and 80 mg / L, 5 adults of golden squid were tested at each concentration, the final degree of anesthesia reached by golden squid within 24 hours was determined, and the final anesthesia was observed. The behavioral characteristics in the state, and then transferred to clean seawater for resuscitation, the behavioral characteristics during the resuscitation process were observed, and then the degree of anesthesia and the resuscitation process were staged.

[0028] Test results: 1) According to the behavioral characteristics under the final anesthesia state, the degree of anesthesia was divided into six periods, as shown in Table 1.

[0029] Table 1 Stages of anesthesia degree and beha...

Embodiment 2

[0036] In June 2012, we transported 250 adult golden squid from Qingdao Jinshatan Aquatic Development Co., Ltd. to Tianjin Xinyongfeng Aquaculture Co., Ltd. Use ice cubes for transport water to cool down from 24°C to 18°C, add 7 mg / L MS-222 and then fill with nano-air stone to saturation; add ice cubes or ice bottles to the golden squid culture pond that has been fasted for 1 day to cool down, after 2 Step by step cooling treatment, 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. The fins stopped swinging and the sense of balance was lost. Immediately, gently fish the golden squid into the washbasin. After weighing, slowly take it out by hand and put it into a black plastic bag with 10L of water for transportation. Each bag contains 1 adult golden squid. , squeeze out the air in the bag, fill with about 30L of oxygen, tie the bag with a rubber band and put it int...

Embodiment 3

[0038]In July 2012, we transported 150 adult golden squid from the Huangdao Golden Squid Experimental Base of the Yellow Sea Fisheries Research Institute to the Xinhaixin Nursery in Xiapu, Fujian. Use ice cubes for transport water to cool down to 16°C, add 8mg / L MS-222, and then use nano-air stone to fill with pure oxygen to saturation; add ice cubes or ice bottles to the golden squid culture pond that has stopped eating for 1 day to cool down, after 3 times The temperature was lowered to 16°C with a temperature difference of no more than 5°C each time; then MS-222 with a final concentration of 60 mg / L was added. After 3 minutes, the golden squid entered an anesthesia state for stage 4, that is, the wrists spread out and the lateral fins stopped. Swing, the sense of balance is lost. Immediately take the golden squid gently into the washbasin. After weighing, slowly take it out by hand and put it into a black plastic bag with 10L water for transportation. Put 1 adult golden squi...

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 particularly relates to a long-distance transportation method for adults of golden squid. Background technique [0002] Under natural conditions, when encountering danger, ink jetting is an escape behavior of cephalopods. The jetted ink can turn the nearby seawater black, thus concealing itself and escape with the help of a fast jet of water. In addition, the ink also contains toxins, which also have a certain offensive effect on the enemy. It was also found in the breeding process that cephalopods are also very prone to inkjet behavior during broodstock acquisition, tank dumping operations, and fighting between individuals, especially during bagging, weighing and transportation before long-distance transportation. for serious. The ink-jet behavior of cephalopods during transportation not only damages the physique, but also easily corrupts the water quality, resulting in a low ...
