Problems solved by technology

[0004] However, as a commonly used clinical drug, eugenol has a wide range of pharmacological activities, especially in the physiological activities of antibacterial and anti-inflammatory, insecticidal, anthelmintic, anti-oxidation and anti-aging. However, due to its strong volatility, The immiscibility with water greatly limits its application as an anesthetic for aquatic products

Embodiment 1

[0021] 1) Select the carp to be sold, raise it for one day, and control the water temperature at 16°C;

[0022] 2) Eugenol emulsification treatment: first mix Tween 80 and Span 80 with a volume ratio of 2:1, then add absolute ethanol with a volume fraction of 0.5 and eugenol with a volume fraction of 0.8, and finally slowly add Wahaha Pure water, after standing still for 5 minutes, pour into water;

[0023] 3) Put the carp one by one into the eugenol emulsion water treated in the above steps with a concentration of 18 mg / L to anesthetize them to prolong the fresh life time.

Embodiment 2

[0025] 1) Select the carp to be sold, raise it for one day, and control the water temperature at 20°C;

[0026] 2) Eugenol emulsification treatment: first mix Tween 80 and Span 80 with a volume ratio of 2.2:1.2, then add absolute ethanol with a volume fraction of 0.55 and eugenol with a volume fraction of 1, and finally slowly add Wahaha Pure water, after standing still for 5 minutes, pour into water;

[0027] 3) Put the carp one by one into the eugenol emulsion water treated in the above steps with a concentration of 20mg / L to anesthetize them to prolong the fresh life time.

Embodiment 3

[0029] 1) Select the silver carp for sale, raise them for one day, and control the water temperature at 22°C;

[0030] 2) Eugenol emulsification treatment: first mix Tween 80 and Span 80 with a volume ratio of 2.5:1.3, then add absolute ethanol with a volume fraction of 0.6 and eugenol with a volume fraction of 1.3, and finally slowly add Wahaha Pure water, after standing still for 6 minutes, pour into water;

[0031] 3) Put silver carp one by one into the eugenol emulsion water treated in the above steps with a concentration of 22mg / L to anesthetize them to prolong the fresh life time.

[0032] Use the eugenol emulsion of the present invention and the eugenol alcohol solution of the 201510948993.X "A Method for Improving the Liveness Rate in Carp Transport" applied by the applicant on December 18, 2015 to do the LD50 experiment, and the test results show that: cloves The median lethal dose of phenol emulsion to carp is about 2 times higher than that of eugenol alcohol soluti...

Abstract

The invention discloses a method for prolonging fresh time of carps in transportation. The method comprises the steps that firstly, the carps on sale are selected to be fed for a day, and the water temperature is controlled to be 16-22 DEG C; secondly, eugenol is subjected to emulsifying treatment: Tween 80 and span 80 in a volume ratio of (2-2.5) to (1-1.3) are mixed, then 0.5-0.6 part by volume of absolute ethyl alcohol and 0.8-1.3 parts by volume of eugenol are added, finally, pure water is added slowly, and finally the mixture stands for 5-6 min and is poured into water; thirdly, the carps are put into eugenol emulsion water in concentration of 18-22 mg / L one by one for anesthesia, so that the fresh time is prolonged. The eugenol is prepared into the eugenol emulsion, water solubility, dispersity and stability of the eugenol in water are improved, the carp anesthesia maintenance time is prolonged remarkably, revival time of the carps in clear water is made to be prolonged apparently, long off-water operation time is obtained in production, more complicated treatment is completed, and damage to the carps is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquatic products, and in particular relates to a method for prolonging the live time of carp in transportation. Background technique [0002] With the rapid development of the aquatic industry, it also promotes the research on the opening, processing, transportation and disease treatment of aquatic products. Because the stress response and hypoxia of fish will be caused in the process of artificial domestication, reproduction, transportation and sales of fish, which will reduce the resistance of fish, resulting in low survival rate and short survival time, resulting in increased cost . At present domestically, fish are mainly sold in a fresh and alive way, wherein the survival rate of carp directly affects the price and benefit of sales in the sales process. Therefore, in order to improve the survival rate of carp and prolong the fresh and alive time of carp in transportation, it is necessary to seek wa...
