Embodiment 1

[0052] Example 1: High-density transportation of crucian carp.

[0053] Adopt the device of the present invention, carry out the transportation experiment of high-density crucian carp.

[0054] In summer (ambient temperature 30°C), the fish-water ratio is 1:1 and 1:10 (weight ratio), the transport water temperature is controlled at 4-7°C, and the dissolved oxygen concentration is controlled at 8-10mg / L. The raw material is crucian carp with a size of 15-20cm, about 200kg. Adopt live fish transport vehicle of the present invention to transport crucian carp to transport 72h with the speed of about 60km / h. Compared with conventional transportation, the mortality rate of crucian carp was measured during the 72h transportation process, and the results are shown in Table 1.

[0055] Table 1 The 72h mortality rate (%) of crucian carp with different transport densities

[0056]

[0057] As can be seen from Table 1, when the density of the crucian carp transported by the present ...

Embodiment 2

[0058] Example 2: Transportation of yellow catfish at different temperatures.

[0059] The device of the present invention is used to carry out transport experiments of yellow catfish at different temperatures.

[0060] 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 15-20cm, about 200kg. Transport vehicle and transportation distance, vehicle speed, time are as embodiment 1. The mortality and oxygen consumption of the yellow catfish were measured during the 24h transportation. Mortality was determined through real-time manual observation and recorded statistics, the results are shown in Table 2;

[0061] The consumption of oxygen is recorded by the pressure value of the oxygen cylinder at different times, according to the state equation of ideal gas PV=nRT, where P(Pa...

Embodiment 3

[0068] Embodiment 3: Water quality pretreatment before transportation and dormancy pretreatment of fish

[0069] The crucian carp is transported by the device and the transport method of the invention, the water quality pretreatment and the dormancy pretreatment of the fish are carried out, and the survival rates of different pretreatment methods are compared.

[0070] In summer (ambient temperature 30°C), the ratio of fish to water is 1:1, and crucian carp with a size of 15-20cm is used as raw material, totaling 200kg. Transport vehicle model and transport distance, vehicle speed, time are as embodiment 1.

[0071] Water quality pretreatment: adjust the water temperature in the fish tank of the live fish transport vehicle to 4-7°C, and at the same time adjust the dissolved oxygen in the water to 10-15mg / L to complete the water quality pretreatment;

[0072] Dormancy pretreatment of fish: fasting the fish, putting them into the temporary breeding tank, adjusting the water tem...

Abstract

The invention discloses a high-density living fish transporting vehicle and a transporting method thereof. The high-density living fish transporting vehicle comprises a vehicle body, a water oxygen circulation system and a fish tank, wherein the fish tank and the water oxygen circulation system are fixedly arranged on the vehicle body; the fish tank is internally provided with partitions; the outer wall of the fish tank is a sandwiched hollow heat-preservation layer; a fish feeding hole is formed in the top surface of each compartment; a fish discharge hole is formed in a side surface of each compartment; the water oxygen circulation system comprises a filtering device, an oxygen enriching device and a heat exchanger which are serially connected with the fish tank through a water pump, pipelines and valves; water dissolved oxygen and temperature are automatically controlled; the pump and a refrigeration compressor are driven by a vehicle-mounted engine; before being loaded, living fishes are subjected to dormancy pretreatment and water quality conditioning firstly, and circulation, temperature and oxygen dissolution control on a water body are implemented in the transportation process. By adoption of the structure and the method, the temperature inside the fish tank is controlled to be higher than the physiological ice temperature of 0.5-8 DEG C of the living fishes, and the water dissolved oxygen is controlled to be approximate to the physiological oxygen requirement, so that physiological metabolism of the living fishes can be reduced to the minimum level, the living fish transportation time can be prolonged, the survival rate can be increased, and the oxygen consumption can be reduced.

Description

technical field [0001] The invention relates to the field of aquatic product transportation, in particular to a high-density live fish transportation vehicle and a transportation method. Background technique [0002] The transportation of live fish includes the transportation of fry, fingerlings and broodstock, which is an indispensable link in the production process of fish farming. Because live animals have very strict requirements on the time and conditions of transportation, there has always been a bottleneck in the transportation of live aquatic products. In order to avoid the death of fish, the transport water body needs to ensure sufficient dissolved oxygen, suitable temperature and good water quality.
