Embodiment 1

[0013] Embodiment 1: The live transport pH stabilizer of Shishouidae fish contains by parts by weight:

[0014] Primary stabilizer: 42.59 parts Na 2 HPO 4 , 4.54 KH 2 PO 4 ; Osmotic pressure regulator: 0.8 part CaCl 2 . By adopting the combined reagent, the pH of the solution transported by the living body can be stabilized between 7.73 and 7.78, which is more suitable for the life activities of the cichlidae. According to the experiment, by adding this proportion of main stabilizer to the seawater transported to the live carapaceidae, 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. CaCl 2 It can regulate the osmotic pressure of cichlidae, maintain its normal metabolism under environmental stress in transport water, and has short-term antibacterial effect. Because the body surface of cichlid fish is hard, the use of anesthetics for live transportation like other bony fish can reduce its...

Embodiment 2

[0020] Embodiment 2: The live transport pH stabilizer of Shishouidae fish contains by parts by weight:

[0021] Primary stabilizer: 43.35 parts Na 2 HPO 4 , 3.81 KH 2 PO 4 ; Osmotic pressure regulator: 6 parts CaCl 2 . This example lists the anhydrous state of the above-mentioned active ingredients. If the hydrate form of the above-mentioned reagents is used, this can be converted according to the active ingredients of this formula.

[0022] Synergist: 0.03 part EDTA.

[0023] Solvent: the remaining parts by weight are seawater, and the volume is adjusted to 5L; the salinity of seawater is 20. Seawater should be sterilized sand-filtered seawater.

[0024] During use, first take a small amount of seawater, add 0.03 parts of EDTA and 6 parts of CaCl 2 , after dissolving, divide into two parts for use; the purpose of this step is to remove interfering ions first.

[0025] Take the above amount of main stabilizer, Na 2 HPO 4 Dissolve in the above-mentioned portion of ED...

Abstract

The invention aims at providing a sciaenidae live transportation pH stabilizer. The stabilizer comprises a main stabilizer and an osmotic pressure regulator, wherein the main stabilizer comprises the following components in parts by weight: 42.59 to 43.35 parts of Na2HPO4, and 4.54 to 3.81 parts of KH2PO4; and the osmotic pressure regulator comprises 0.8 to 6 parts by weight of CaCl2. The pH stabilizer has the advantages of improving the live transportation effect of sciaenidae parents, and stabilizing the pH value of transporting water body with harmlessness to fish organs, low cost and no food safety risk.

Description

technical field [0001] The invention relates to a special chemical reagent for the transportation of aquatic animals, in particular to a pH stabilizer for the transportation of live chrysocephalaceae fish. 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 j...
