Embodiment 1

[0022] (1) Temporary maintenance: Select healthy and vigorous flounders and place them in seawater supplemented with a preservative of 3% of the seawater mass for 2 days. The preservative is composed of the following components by mass: 5% sulfuric acid Magnesium, 1.5% potassium chloride, 2.5% magnesium bromide, 7.5% rosmarinic acid, 0.0025% aldosterone, and the balance is water. During the temporary incubation period, ozone was introduced into the seawater for 0.5min every 5h to make the ozone concentration in the seawater. kept at 0.1 mg / L.

[0023] (2) Gradient cooling: Cool the seawater. When the seawater temperature is above 10°C, the cooling rate is 2°C / h; when the seawater temperature is 1°C, the cooling rate is 0.8°C / h, and when the seawater temperature is 1°C Below, the cooling rate is 0.3°C / h, and the seawater temperature is reduced to -0.5°C according to this cooling rate.

[0024] (3) Packing and oxygenation: Take the flounder out of the seawater and put it into a...

Embodiment 2

[0027] (1) Temporary maintenance: Select healthy and vigorous flounders and place them in seawater supplemented with a preservative of 4% seawater mass for 1 day. The preservative is composed of the following components by mass: 10% sulfuric acid Magnesium, 3.5% potassium chloride, 6.5% magnesium bromide, 15% rosmarinic acid, 0.0065% aldosterone, and the balance is water. During the temporary incubation period, ozone was introduced into the seawater for 1min every 6h to keep the ozone concentration in the seawater. at 0.5mg / L.

[0028] (2) Gradient cooling: Cool the seawater. When the seawater temperature is above 10°C, the cooling rate is 4°C / h. When the seawater temperature is 1~10°C, the cooling rate is 1°C / h. When the temperature is below 1°C, the cooling rate is 0.5°C / h, and the seawater temperature is reduced to 1.5°C according to this cooling rate.

[0029] (3) Packing and oxygenation: Take the flounder out of the seawater and put it into an anhydrous double-layer infl...

Embodiment 3

[0032] (1) Temporary maintenance: Select healthy and vigorous flounders and place them in seawater with 3.5% of seawater quality preservative added for 1.5 days. The preservative is composed of the following components by mass: 7% sulfuric acid Magnesium, 3% potassium chloride, 5% magnesium bromide, 10% rosmarinic acid, 0.0035% aldosterone, and the balance is water. During the temporary holding period, ozone was introduced into the seawater for 0.6min every 5.5h to make the ozone in the seawater. The concentration was kept at 0.3 mg / L.

[0033] (2) Gradient cooling: Cool the seawater. When the seawater temperature is above 10°C, the cooling rate is 3°C / h; when the seawater temperature is 1~10°C, the cooling rate is 0.9°C / h. When the temperature is below 1 °C, the cooling rate is 0.4 °C / h, and the seawater temperature is reduced to 1 °C according to this cooling rate.

Abstract

The invention discloses a paralichthys olivaceus transportation method of paralichthys olivaceus capable of keeping paralichthys olivaceus alive without water, including the following steps: (1) temporary culturing: choosing and putting healthy and energetic paralichthys olivaceus into seawater with an alive keeping agent and performing temporary culturing for 1-2d; (2) gradient cooling: cooling the seawater, when the water temperature is above 10 DEG C, the cooling rate is 2-4 DEG C/h, when the water temperature is 1-10 DEG C, the cooling rate is 0.8-1 DEG C/h, and when the water temperature is below 1 DEG C, the cooling rate is 0.3-0.5 DEG C/h, reducing the seawater temperature to -0.5-1.5 DEG C according to the cooling rate; (3) packaging and oxygen filling: taking the paralichthys olivaceus out of the seawater, and quickly putting the paralichthys olivaceus in an anhydrous double-layer inflatable bag, filling pure oxygen, and sealing the bag; and (4) temperature controlling and transporting: putting the anhydrous double-layer inflatable bags into -0.5-1.5 DEG C environment, and transporting the bags. The inventive method has the advantages of easy operation, low transportation cost, no pollution and high quality, is suitable for long-distance transportation, and is beneficial to improving the economic value of paralichthys olivaceus.

Description

technical field [0001] The invention relates to the technical field of water-free water-preserving transportation of aquatic products, in particular to a water-free water-preserving transportation method for flounder. Background technique [0002] The flounder is commonly known as tooth flakes, partial mouths, and flounder in my country. It is a precious marine fish and one of the important marine fish. Its body is huge, the meat is tender and delicious, it is the first-class material for making sashimi, it is deeply loved by consumers, the market is very broad, and the economic value is very high. The flounder occupies a certain position in my country's fishery history, but in the past 20 to 30 years, due to overfishing and environmental pollution, natural resources have declined significantly, and there has been a contradiction between supply and demand, which has prompted people to go to the road of aquaculture. [0003] However, there is often a distance between the b...
