Problems solved by technology

During the transportation process, the portunus trituberculatus in the transport device will inevitably fight and cannibalize each other, which will lead to broken limbs and incomplete samples of the Portunus trituberculatus samples transported back to the laboratory, which will eventually affect the biological determination
In addition, when selling caught Portunus trituberculatus, the price of dead or incomplete Portunus trituberculatus is only about half of the price of healthy and fresh Portunus trituberculatus, and because aquatic products are easy to spoil after death, they must be sold in a short period of time. Sell ​​within time, otherwise the loss will be bigger

Embodiment 1

[0039] A transportation method capable of reducing fighting injuries of Portunus trituberculatus, comprising the following steps:

[0040] (1) Disinfect the transport device with potassium permanganate solution, rinse with clean seawater to remove residual potassium permanganate;

[0041] (2) process portunus trituberculatus with tranquilizer;

[0042] (3) Put Portunus trituberculatus into the transport device, slowly adjust the temperature in the transport device to 6°C with a temperature change range of 0.5°C / min, and keep the temperature in the transport device at 2- 8°C.

Embodiment 2

[0044] A transportation method capable of reducing fighting injuries of Portunus trituberculatus, comprising the following steps:

[0045] (1) Disinfect the transport device with potassium permanganate solution, rinse with clean seawater to remove residual potassium permanganate;

[0046] (2) process portunus trituberculatus with tranquilizer;

[0047] (3) Put Portunus trituberculatus into the transport device, slowly adjust the temperature in the transport device to 4 °C with a temperature change range of 0.4 °C / min, and keep the temperature in the transport device at 2- 8°C.

Embodiment 3

[0049] A transportation method capable of reducing fighting injuries of Portunus trituberculatus, comprising the following steps:

Abstract

The invention relates to a transporting method capable of reducing fighting injury of swimming crabs, and further relates to a transporting device capable of reducing the fighting injury of the swimming crabs. The transporting method comprises the following steps: (1) sterilizing the transporting device by using potassium permanganate solution, washing by using clean sea water, and removing the residual potassium permanganate; (2) processing the swimming crabs by using a tranquilizer; and (3) enabling the swimming crabs to be placed in the transporting device, slowly regulating a temperature in the transporting device to 2-8 DEG C in 0.4-0.6 DEG C / min of a temperature variation amplitude, and enabling the temperature in the transporting device to be always kept in 2-8 DEG C during a transporting process. Compared with the prior art, the transporting method has the advantage of improving transporting survival rate and integrity rate of the swimming crabs.

Description

technical field [0001] The invention relates to a transportation method for reducing fighting injuries of portunus trituberculatus, and also relates to a transportation device for reducing fighting injuries of swimming crabs trituberculatus. Background technique [0002] Portunus trituberculatus is an important cultured species. During the research on Portunus trituberculatus, it is often necessary to regularly collect samples at designated locations and transport the samples back to the laboratory for biological assays. During the transportation process, the Portunus trituberculatus in the transport device will inevitably fight and cannibalize each other, which will lead to broken limbs and incomplete samples of Portunus trituberculatus samples transported back to the laboratory, which will eventually affect the biological determination. In addition, when selling caught Portunus trituberculatus, the price of dead or incomplete Portunus trituberculatus is only about half of...
