Embodiment 1

[0016] Embodiment 1: the pH stabilizer for squid living transport, which contains by parts by weight:

[0017] Primary stabilizer: 39.75 parts Na 2 HPO 4 , 7.26 KH 2 PO 4 ;

[0018] Osmotic pressure regulator: 0.25 part CaCl 2 .

[0019] By adopting the combined reagent, the pH of the solution transported by the living body can be stabilized between 7.5 and 8.5, which is more suitable for the life activities of squid. According to the experiment, by adding the main stabilizer in this proportion to the seawater transported to live squid, 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 squid and maintain its normal metabolism under the environmental stress of transport water. Due to the fierce nature of squid, the phenomenon of mutual mutilation among the same species is quite serious. Generally, anesthetics are used for live transportation,...

Embodiment 2

[0026] Embodiment 2: squid living transport pH stabilizer, which contains by weight parts:

[0027] Primary stabilizer: 46.57 parts Na 2 HPO 4 , 0.73 KH 2 PO 4 ;

[0028] Osmotic regulator: 2.5 parts CaCl 2 .

[0029] It also contains in parts by weight: synergist: 0.03 part of EDTA. According to parts by weight, it also contains: solvent: the remaining parts by weight are seawater, which is fixed to 5L; the salinity of seawater is 22‰. Seawater should be sterilized sand-filtered seawater.

[0030] During use, first take 4L of seawater, add 0.03 parts of EDTA and 2.5 parts of CaCl 2 , after dissolving, divide into two parts for use; the purpose of this step is to remove interfering ions first.

[0031] Take the above amount of main stabilizer, Na 2 HPO 4 Dissolve in the above-mentioned portion of EDTA-treated seawater, KH 2 PO 4 Dissolved in another portion of EDTA-treated seawater as above;

[0032] Finally, the two parts of seawater were mixed, and the above-me...

Abstract

The invention discloses a pH stabilizer for transporting cuttlefish live bodies. The pH stabilizer comprises the following components in part by weight: 39.75 to 46.57 parts of Na2HPO4, 7.26 to 0.73 parts of KHPO4, 0.25 to 2.5 parts of osmotic pressure regulator and 0.25 to 2.5 parts of CaCl2. The pH stabilizer has the advantages of improving a live body transporting effect of cuttlefish parents, stabilizing the pH value of a transport water body, and having no damage to internal organs of fish, low cost and no 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 squid 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 see...
