Problems solved by technology

At present, the logistics of aquatic products in China lacks unified logistics standards and quality and safety standards. The main manifestations are: non-standardized logistics equipment, facilities, and behaviors are still quite common; the classification and grading of aquatic products are mostly based on manual feelings, and the errors are too large
[0004] Chinese patent CN96107817.0 discloses an automatic loading and unloading live fish transport box, which includes a transport box body, a water circulation system, an oxygen-increasing gas distribution device, a sewage purification device, an auxiliary device for loading and unloading fish, and a power unit. The main advantages of the device are: It is more convenient to load and unload fish, but the device does not have a water temperature adjustment device, so it cannot realize low temperature preservation and transportation
Chinese patent CN03239496.9 discloses a temperature regulating device for a live fish transport ship. The temperature raising device of the temperature regulating device adopts a hot oil circulation heating method. The structure is complicated and a fuel oil boiler needs to be loaded. Realization of refrigeration compressors
Chinese patent CN200920279049.X discloses a vehicle-mounted live fish transport box. The transport box does not have a water circulation filter device, so it is difficult to ensure the water quality during long-distance transportation. In addition, the transport box does not have a water temperature adjustment device, so it cannot be kept alive at low temperature transportation
Patent CN102812918A discloses a transportation device for freshwater fish at low temperature. This transportation device realizes automatic temperature control, but the aeration tube is used for increasing oxygen, and the effect of dissolved oxygen is slow. There is no foam separation device, and the filtration system occupies a certain area. higher cost

Embodiment 1

[0044] Embodiment 1: High-density transportation of crucian carp.

[0045] In summer (ambient temperature 30°C), the fish-to-water ratio is 1:1, the transport water temperature is controlled at 6.5±1°C, and the dissolved oxygen concentration is controlled at 8-10mg / L. The raw material is crucian carp with a size of 15-20 cm, and a Dongfeng CLW5110GNY4 live fish transport vehicle with a load of 16 tons is used to transport 10 tons of crucian carp at a speed of 60 km / h for 24 hours. Specific vehicle-mounted fish farming devices such as figure 2 As shown, among them, the outer wall of the water inlet pipe and the water outlet pipe are wrapped with three layers of synthetic fiber pleated biochemical cotton with a specification of 100*200*38mm, and Bdellovibrio, which is resistant to low temperature, is cultivated on the biochemical cotton at a concentration of 4× 107CFU / m 3 , and compound an appropriate amount of VC. Compared with the conventional transport box, the changes in...

Embodiment 2

[0058] Embodiment 2: Different density transportation of yellow catfish.

[0059] In summer (ambient temperature 30°C), the fish-water ratio is 1:1 and 1:10 respectively, the transport water temperature is controlled at 10±1°C, and the dissolved oxygen concentration is controlled at 8-10mg / L. The raw material is yellow catfish with a size of 15-20 cm. The model of the transport vehicle and the transport distance, speed, time, filter cotton specification and microbial concentration are as in Example 1. The changes of protein concentration and ammonia nitrogen concentration in the water body of the yellow catfish were measured during the 24h transportation. Among them, the concentration of water-soluble protein is determined by the method of GB / T18868-2002; the method of ammonia nitrogen is determined by the method of HJ535-2009. The result is as follows:

[0060] Table 5 Water body protein concentration (mg / mL) of different transport densities of yellow catfish 24h

[0061] ...

Embodiment 3

[0066] Example 3: Transport of yellow catfish at different temperatures.

[0067] In summer (ambient temperature 30°C), the fish-to-water ratio is 1:10, the transport water temperature is controlled at 10°C, 15°C, and 20°C, and the dissolved oxygen concentration is controlled at 8-10mg / L. The raw material is yellow catfish with a size of 15-20 cm. The model of the transport vehicle and the transport distance, speed, time, filter cotton specification and microbial concentration are as in Example 1. The changes of respiratory rate and mortality of the yellow catfish were measured during the 24h transportation. The result is as follows:

[0068] Table 7 Respiratory frequency of yellow catfish at different transport temperatures for 24 hours

[0069]

[0070] It can be seen from Table 7 that when the temperature of the transported yellow catfish in the present invention is 10°C, there is no significant difference between the respiratory rate of the transported yellow catfish ...
