Embodiment 1

[0025] A method for low-temperature transportation of live redfin puffer fish, said method comprising the steps of:

[0026] ①The healthy redfin pufferfish with normal swimming, no damage on the body surface and complete fin rays were baited for 24 hours and then transferred to a holding pond with a water temperature of 15°C, and then transferred to a holding pond with a water temperature of 12°C after holding for 12 hours. After holding temporarily for 2 hours, transfer to holding pool with water temperature of 8°C until it becomes unresponsive, lying on the bottom, and no longer swims in a quiet state;

[0027] ②Put a single redfin fugu in a quiet state into a 20-mesh sieve silk monomer packaging net, and put the monomer packaging net into a monomer packaging filled with seawater with a water temperature of 8°C, a salinity of 29‰, and a pH value of 7.9 In the bag, fill the seawater with oxygen until the oxygen content is 10-12mg / L, the mass ratio of seawater to pufferfish is...

Abstract

The invention relates to a method for transporting live fugu rubripes at a low temperature. The method includes the steps of conducting temporary cultivation at a low temperature, and packing each fugu rubripe, namely, loading each fugu rubripe which is in a quiet state into a single body packaging net, loading the single body packaging nets into single body packaging bags containing seawater with the water temperature ranging from 7 DEG C to 8 DEG C, the salinity ranging from 2.5% to 3.2%, the pH value ranging from 7.8 to 8.3 and the oxygen content ranging from 10mg/L to 12mg/L, and loading the plurality of sealed single body packaging bags into a thermal insulation box, wherein the mass ratio of the seawater to the fugu rubripes is 1:1.5-2. The method has the advantages that the survival rate of the transported fugu rubripes is 100%, and the longest transportation time can be 18 hours.

Description

technical field [0001] The invention relates to a method for transporting live redfin puffer fish at low temperature. Background technique [0002] The red-finned puffer (Takifugu rubripes) is a carnivorous fish at the bottom of warm-temperate coastal waters. It is mainly distributed in the western North Pacific Ocean, between the south of Hokkaido, Japan and the north of Taiwan Province of China. The fish is delicious and nutritious, and it is an important biological species with a high nutritional level in the East and Yellow Sea ecosystems. Over the years, due to overfishing, resources have been depleted, and the catch has dropped sharply, making artificial breeding and release an important means of maintaining the market and natural resources. At present, large-scale farming has been formed in the northern part of my country, and most of the products are exported to Japan and South Korea. They have become the most important high-end species of export-earning foreign exc...
