Embodiment Construction

[0015] In order to make the operation flow and creation features realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.

[0016] Materials and Methods

[0017] 1.1 Materials

[0018] The groupers used in the experiment were purchased from Luchao Port, Pudong New Area, Shanghai. The same batch of groupers were selected to be healthy and free of disease, with an average body length of (27.50±1.55) cm and an average weight of (500±120) g. In the laboratory, they were temporarily cultured in a 120L culture pond in the laboratory, and were temporarily cultured for 7 days without food, during which time they were continuously aerated, and 50% of the water was changed every day during the temporary culture.

Abstract

The invention relates to a marine fish water survive transportation method. The method briefly comprises the steps of 1, temporary culture, wherein temporary culture is conducted 1-12 d before transportation; 2, transportation box temperature adjustment, wherein the water temperature of a survive fish transportation box is adjusted to be the optimum temperature of 15-27 DEG C from 27 DEG C according to the temperature change rate being 0.1-1 DEG C / h before transportation; 3, transportation, wherein an aquarium is placed on a low-temperature cold storage transportation vehicle for transportation, in the transportation process, the temperature of the low-temperature cold storage transportation vehicle is kept at the temperature being 15-27 DEG C required by the aquarium, and the salinity ofwater in the aquarium is 1-3%. After treatment is conducted by means of the survive process, the serum cortisol, blood glucose concentration and HSP70 expression quantity can be significantly lowered,a stress reaction triggered in the transportation process is lowered, and survival rate is increased.

Description

technical field [0001] The invention relates to the field of aquatic product transportation, in particular to a water-preserving transportation method for marine fish. Background technique [0002] Grouper (Epinephelus) belongs to the family Serranidae. It is a warm-water fish that inhabits tropical and subtropical waters. It is mainly cultured in the coastal areas of Hainan, Guangdong, Fujian and Zhejiang in my country. Grouper is favored by consumers because of its high protein content, low fat content, a variety of essential amino acids, inorganic salts and various vitamins, and its tender meat and good taste. It has high market value and consumer demand. It is an economically important marine fish. [0003] According to data from the China Fisheries Statistical Yearbook in recent years, Hainan, Guangdong and Fujian are the main provinces for grouper aquaculture in mainland China, and their total aquaculture volume accounts for 95% of China's aquaculture volume, and in 2...
