Problems solved by technology

[0003] Seawater grouper is produced in sea areas. Due to the large production and sales area and immature preservation technology, etc., the transportation cost is high and the mortality rate of grouper during transportation is high, which leads to the increase in the cost of grouper. Take advantage of the development of its sales market

Embodiment 1

[0035] (1) In September 2017, 50 pearl gentian groupers (average weight 550g) to be transported were placed in the laboratory's live-keeping transport system. The keep-alive transportation system is equipped with a cyclone protein separator, a biomechanical filter, a refrigerator, and a PP holding tank with a volume of 1 cubic meter. The fish body was kept alive for 48 hours in 330L of natural purified seawater with a salinity of 25‰ and a dissolved oxygen of 7.0-8.0 mg / L at 25°C. The refrigeration unit was turned on for program cooling, and the temperature was lowered to 13°C. , let the pearl gentian grouper enter a dormant state;

[0036] (2) Take out the dormant pearl gentian grouper from the seawater and quickly put it into an anhydrous double-layer survival bag, fill it with pure oxygen and seal it, then put the survival bag in a foam box, and transport it The foam box is placed in an environment of 15-18°C for preservation and transportation.

[0037] Among them, the p...

Embodiment 2

[0040] The process of this embodiment is the same as that of Example 1, the difference is that the seawater grouper is temporarily raised for 48 hours, and the programmed cooling process is: the cooling rate is 2.5°C / h, and the water temperature is reduced from 25°C to 20°C for 2 hours; At a rate of 2°C / h, the water temperature will drop from 20°C to 15°C after 2.5 hours; at a cooling rate of 0.8°C / h, the water temperature will drop from 15°C to 13°C after 2.5 hours.

[0041] The time was counted from the end of oxygenated packaging in the water-free survival bag, and after 8 hours of water-free transportation, the survival rate was 98%.

Embodiment 3

[0043] The process of this embodiment is the same as that of Example 1, except that the seawater grouper used is the oblique-banded grouper, and the holding time is 24 hours. The programmed cooling process is: the cooling rate is 2.5°C / h, and the water temperature is increased by 2 hours. 25°C to 20°C; the cooling rate is 2°C / h, and the water temperature drops from 20°C to 15°C after 2.5 hours; the cooling rate is 1°C / h, and the water temperature drops from 15°C to 13°C after 2 hours.

[0044] The time was counted from the end of oxygenated packaging in the water-free survival bag, and after 8 hours of water-free transportation, the survival rate was 96%.

Abstract

The invention provides a method for waterless transportation of sea groupers. The method comprises the following steps that S1, the live sea groupers are not fed and placed in seawater for temporary raising, and then the seawater is subjected to programmed cooling to a temperature of 13 to 14 DEG C; and S2, the seawater groupers treated with S1 are placed in an anhydrous alive-keeping bag having ahumidity of 90% or more, and the bag is filled with oxygen, then sealed and transported in a transport box at a temperature of 15 to 18 DEG C. The programmed cooling method in step S1 includes the steps that, when the seawater temperature is 20 DEG C or above, the cooling rate is 2-3 DEG C / h; when the seawater temperature is 15-20 DEG C, the cooling rate is 1-2 DEG C / h; and when the seawater temperature is below 15 DEG C, the cooling rate is 0.5-1 DEG C / h. The waterless transportation method is suitable for the development of the e-commerce logistics industry in modern cities, and achieves the direct transportation from the factory to the home. Compared with the water-containing transportation of groupers on the current market, the method greatly reduces the transportation cost and is conducive to the development of the grouper market.

Description

technical field [0001] The invention belongs to the field of seawater grouper transportation, and more specifically relates to a waterless transportation method for seawater grouper. Background technique [0002] Seawater grouper is widely distributed in tropical and subtropical waters, and is a rare and valuable fish at the bottom of warm water offshore. Its suitable temperature range is 15-34°C, and the optimum water temperature is 22-28°C; its suitable salt range is wide, and it can survive in sea areas with a salinity above 10‰. Seawater grouper is a carnivorous and fierce fish that preys on benthic crustaceans, various small fishes and cephalopods in a surprise manner. Seawater grouper is rich in nutrition, tender and white, similar to chicken, known as "sea chicken", because of its high polyunsaturated fatty acid and protein content, high use value and health care value, it is promoted by Hong Kong and Macao as the Chinese food. One of the four famous fish. [0003]...
