Embodiment 1

[0014] Embodiment 1: octopus live transport pH stabilizer, it contains by weight parts:

[0015] Primary stabilizer: 132.96 parts Na 2 HPO 4 , 6.1 parts citric acid. By adopting the combined reagent, the pH of the solution transported by the living body can be stabilized between 7.6 and 8.0, which is more suitable for the life activities of the octopus. According to the experiment, by adding the main stabilizer in this proportion to the seawater transported to the living octopus, the pH of the water body is relatively stable within 1d to 3d, and the change range of pH is smaller than that of the control group. Generally, anesthetics are used for live transportation, and the effect on octopus transportation is not obvious. The body surface of octopus is soft, and it will not cause infection due to friction between fish bodies caused by vigorous swimming caused by stress during transportation. Therefore, under normal circumstances, the most traditional double-layer plastic b...

Embodiment 2

[0022] Embodiment 2: octopus live transport pH stabilizer, it contains by weight parts:

[0023] Primary stabilizer: 138.08 parts Na 2 HPO 4 , 4.8 parts of citric acid; synergist: 0.02 part of EDTA; solvent: the remaining parts by weight are seawater, set to 5L; the salinity of seawater is 30‰. Seawater should be sterilized sand-filtered seawater.

[0024] During use, first take 4L of seawater, add EDTA to dissolve it, divide it into two equal parts, and set aside;

[0025] Take the above amount of main stabilizer, Na 2 HPO 4 Dissolve in the above-mentioned one part of the EDTA-treated seawater, and dissolve the citric acid in the above-mentioned other part of the EDTA-treated seawater;

[0026]Finally, the two parts of seawater were mixed, and the above-mentioned sand-filtered seawater was used to adjust the volume to 5 L.

Abstract

The invention discloses a pH stabilizer for octopus living body transportation. The pH stabilizer comprises the following main stabilizers in parts by weight: 132.96-138.08 parts of Na2HPO4 and 6.1-4.8 parts of citric acid. The pH stabilizer has the advantages of improving the living body transportation effect of octopus parents, stabilizing the pH value of the transportation water body, doing no harm to viscera of the octopus and realizing low cost and zero food safety risk.

Description

technical field [0001] The invention relates to a special chemical reagent for aquatic animal transportation, in particular to a pH stabilizer for live octopus transportation. 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 good prices, while aquatic products with poor freshness are just the opposite. It can be s...
