Attention points for long-distance transportation of commercial fish

most commercial fish in the origin must be transported to other places for sale. Therefore, the success or failure of long-distance transportation is directly related to the interests of fish traders and the sale of commercial fish by farmers. Here are some problems that should be paid attention to in the long-distance transportation of commercial fish:

1. Choose the long-distance transportation of adult fish that is physically strong, disease-free and injury free, and also provides various equipment information. Before shipment, farmers should make preparations for the cessation of food and exercise of adult fish

2. Generally, containers (tin cans) and oxygenated vehicles are used for transportation

3. The appropriate shipping density is 500-600 kg per cubic meter of water with a water temperature of about 15 ℃. If the temperature increases, the density should decrease. On the contrary, if the temperature decreases, the shipping density can be appropriately increased. In addition, the shipping density should also be adjusted with reference to the transportation distance and time

4. Change water in time during transportation. Generally, the water is changed every 2-3 hours after loading. The electronic universal testing machine mainly uses the servo speed regulation system, and the water can be changed every 5-8 hours. The water change interval should be flexibly controlled according to the change of water quality and the water source conditions along the way. It is best to change the water from the top to the bottom at the same time. Dead fish and other sundries should be removed in time

5. Ensure adequate oxygen supply. The oxygen supply should be discharged within 3.5-4.5 hours for each bottle of oxygen. Of course, the gas supply volume of the "floating paradise" caused by 150000 plastic bottles should also be referred to the shipping density and transportation distance. When the oxygen is almost exhausted, you should quickly change to another bottle in time

6. During the transportation, check whether the vehicle is in good condition, whether the oxygen supply system is normal, and how the water quality and fish change at an interval of 1-2 hours for each test method of physical and chemical properties of wood-based panels and decorative wood-based panels in gb/t 17657 (1) 999, and take corresponding effective measures in time
