I. Preparation before transport 1. Before transporting lobsters, prepare shrimp transporters. Selection of appliances should be determined according to the length of the transport distance, generally to prepare fishing rods, canvas baskets, plastic buckets, barrels or drums, pouches, snakeskin bags and nylon bags. 2. Before transporting, bait should be kept for 2 days to 3 days before the emptying of the intestines. Facilitate its early adaptation to thrills and high-density transportation environment. In order to maintain the transport of water during transportation, it will not pollute and improve the survival rate of transportation.
Second, there are two main transport methods: water transport and dry transport. Water transport is generally used. The specific methods are as follows: 1. Select the crawfish, which has been grown and maintained after being raised, to be shipped. When shipped, fill the water bag into the container and gently place the crayfish along the container wall. The stocking density should be appropriate. A 10 liter container of wooden barrels or canvas bags can hold 4 to 5 litres of water and 6 to 8 kilograms of crayfish. If the weather is hot and humid, it is necessary to reduce the amount; on the contrary, the weather is clear, the water temperature is low, and the transportation density can be relatively large. 2. Check crayfish activity at any time during transportation. If crayfish are found in the water, they sometimes float in a daze on the surface of the water and continue to exhale small bubbles, indicating that the water quality in the container has changed and the water should be changed immediately. Change the water every 30 minutes, change the water continuously 2 times to 3 times, so that the dirt is basically drained. When changing the water, it is best to choose the pond water or river water that is similar to the original pond water quality. It is not appropriate to use spring water, well water, or polluted canal water. Note that the temperature difference should not be too large. 3. In order to increase the transportation rate, several loach can be put in the container at the same time (usually 1 kg to 1.5 kg in a container), so that the loach can continuously move up and down in the container to increase the dissolved oxygen in the water in the container. Shrimp and shrimp fight each other and reduce the damage rate. If it is transported during the high temperature period, some ice cubes can be placed on the overlay mesh. The melted ice water is continuously dropped into the container to reduce the water temperature, and a small amount of water hyacinth is added to the water to help the crayfish to hold the grass and reduce the amount of water. He died of hypoxia. 4. If transporting for more than one day, turn the crayfish once every 4 to 5 hours, and turn the crayfish that has been sinking in the bottom of the container for a long time to the upper layer to prevent death from hypoxia.
