Embodiment 1

[0020] Embodiment 1: refer to Figure 1 to Figure 2 , the pre-treatment method of cephalopod parent living transportation, it comprises the following steps:

[0021] ① Dissolution at room temperature: Dissolve the anesthetic evenly in a container filled with water, so that the concentration of the anesthetic is 5ppm to 12ppm; 5ppm is preferred in this embodiment.

[0022] ② Gradient cooling: After the treatment in step ①, put the cephalopod parent body into the container, and cool down to 7°C to 18°C ​​through a gradient; in this embodiment, the temperature is preferably lowered to 7°C.

[0023] ③Transportation preparation: after step ②, add NaCl and CaCl to the container 2 , so that the concentration of NaCl in the water increases from 0.5g / L to 3g / L and CaCl 2 The concentration of the drug increased from 50mg / L to 500mg / L. In this embodiment, it is preferable to control the concentration of NaCl in the water body to rise by 0.5g / L, and the concentration of CaCl 2 Concent...

Embodiment 2

[0033] Embodiment 2: refer to Figure 1 to Figure 2 , the pre-treatment method of cephalopod parent living transportation, it comprises the following steps:

[0034] ① Dissolution at room temperature: Dissolve the anesthetic evenly in a container filled with water, so that the concentration of the anesthetic is 12ppm;

[0035] ② Gradient cooling: After the treatment in step ①, put the cephalopod parents into the container, and cool down by 13°C through a gradient;

[0036] ③Transportation preparation: after step ②, add NaCl and CaCl to the container 2 , so that the concentration of NaCl in the water body increases by 2g / L and CaCl 2 The concentration rises by 300mg / L.

[0037] The anesthetic was propyl aniline acetaminobenzoate hydrochloride.

[0038] In step ③, zeolite particles equivalent to twice the weight of NaCl are also added.

[0039] The temperature gradient used for gradient cooling is 0.5°C, and the interval between each gradient is 60 minutes.

[0040] The pr...

Abstract

The invention aims to provide a pretreatment reagent for living body transportation of parents of cephalopods. The pretreatment reagent can improve the effect of living body transportation of parents of cephalopods and has the advantages of simple operation method, low cost, good anesthetic effect, low action concentration, controllable resuscitation time, stable performance and low damage to fish body. According to the invention, aniline hydrochloride acetyl propyl aminobenzoate, a derivative of anthranilic acid, is used as main active component of anesthetic used in pretreatment during the process of living body transportation, which has good anesthetic effect on cephalopods, low action concentration, controllable resuscitation time and stable performance. In addition, after combined use with CaCl2, the anesthetic effect of aniline hydrochloride acetyl propyl aminobenzoate at low-temperature is basically not reduced.

Description

technical field [0001] The invention relates to a chemical reagent and a treatment method for the pre-transportation liquid of aquatic animals, in particular to a pre-treatment method and a special reagent for the transportation of living cephalopod living bodies. Background technique [0002] With the development of fishery, the problem of live fish transportation has aroused great concern. Live fish transportation includes the transportation of fry, broodstock, commercial fish and ornamental fish. In the past, the mortality rate of these fish was very high during transportation, especially in long-distance and high-density transportation. With the continuous improvement of people's living standards, the fresh aquatic product market has undergone tremendous changes in terms of variety, price, supply and marketing system and many other aspects. Judging from the current domestic and foreign markets, aquatic products with good freshness are not only popular, but also have go...
