Green shrimp shrimp long-distance transport of plastic bag oxygenation method, canvas rake method, live water boat method. Each of the three transportation methods has its own advantages and disadvantages. The plastic bags are transported by oxygenation and have a high survival rate, but they are complicated in operation and costly. For example, if 1,000 kg of live shrimp are to be transported, at least 1,000 plastic bags and 500 or more cartons are required. And the durability of plastic bags and cartons is poor, especially when the cartons are scrapped one or two times. Canvas transportation, transport shrimp, there are few, if the journey more than 100 kilometers, the survival rate is low. Live water ships are transported for a long time, and the water quality of the road changes greatly. The above three transportation methods are appropriate for areas where the yield of shrimps is not high or for the transport of broodstock and shrimp. However, they are suitable for transporting more than 1,000 tons of freshwater shrimp each year on the bank of Poyang Lake and need to be transported throughout the year. For Yugan County, it is not so suitable. In recent years, shrimp farmers in our county have used a combination of shrimp tanks to transport live shrimp. In this method, the first is a large number of shrimp, such as 2 ton shrimp, 400-600 kg of shrimp each time, 5 tons of shrimp per 1000-1500 kg; second is a long journey, high survival rate, For example, 600 kilometers from Yugan County to Hangzhou and 1300 kilometers from Hunan to Hangzhou, the trial results show that the survival rate is as high as 80% to 90%. Third, transportation is not subject to seasonal restrictions, regardless of the high temperature season or the low temperature season. Transportation; Fourth, the operation and management are more convenient; Fifth, the cost is low, once investment, can be used for at least 3 years. The shrimp tank combination and shipping method are described as follows: I. Box combination shrimp tanks The combined transport of live shrimp includes shrimp tanks, aeration systems, power systems and shrimp tanks. The overall use of cargo trucks, in accordance with the size of tonnage, the matching truck tonnage is also different. 1. shrimp box. The shrimp box has 5, 3, 2 ton grades in terms of volume. It is made of 3-4 mm thick iron plate with lid. The thickness of the iron plate at the bottom of the shrimp box is 4mm, and the thickness of the iron plate on the box wall, the box upper part and the box lid is 3mm. There is a drain hole in the corner of the bottom of the box. The pipe in the front of the shrimp box and the aeration system in the box. The shrimp box is mounted on the front of the middle of the truck compartment with a thick wire or wire rope. 2. Oxygenation and power system. The aerobic system consists of an oxygen pump, a 50 mm diameter hollow iron tube, a 15 mm diameter tap water pipe, two gate valves, and a corresponding rubber tube. Each shrimp box is equipped with 2 aeration pumps and 2 aeration pumps with 2 sets of 6-12 horsepower. An aeration pump and a power unit are mounted on a single seat, and the belt is used to drive the oxygen pump. It is installed on the front of the shrimp box in the long-distance car box, and is installed on one side. 3. Set shrimp box. The shrimp box is made of 6mm diameter steel, 8th wire, and no knotted mesh. Steel box frame, volume is 854010cm. The shrimp mouth of the shrimp box is located on the wide side of the box. According to the tonnage size of the shrimp tank, a certain number of shrimp tanks, such as 5 ton shrimp tanks, should be equipped with more than 150 shrimp tanks. Second, the method of shipping shrimp 1. The number of shrimp shipped. Depending on the size of the tonnage and the season, the amount of shrimp is also different. In the late autumn, winter and spring, the temperature is relatively low, and a 5-ton shrimp container is shipped with 1500 kg of live shrimp each time. In the late spring, summer and autumn, the temperature is higher, and the 5-ton shrimp container is shipped 1,000 kg of live shrimp. Other tonnage shrimp boxes, the number of live shrimp shipped, converted to 5 tons of shrimp. 2. Packing method. After clearing the dirt in the shrimp box, inject clean water and how much water is injected into the water to allow the person to operate within it. Start the oxygen pump and increase the oxygen level: Then add the shrimp that has been raised for 1-3 days into the set shrimp. Box, each set of shrimp tank capacity of 854,010 cm, 10 kg of shrimp, tightly set shrimp mouth, so that shrimp can not climb out. The shrimp box containing the shrimp is immediately placed flat in the shrimp box. After the first layer of the shrimp box is full, the second layer and the third layer are placed, and so on. Water, cover the lid and ship immediately. In the packing process, the action is required to be brisk and the water is carried. The water in the shrimp box must be submerged in the shrimp box. If the water is not submerged, the shrimp box should be placed after the water injection. In this way, hypoxia will not die due to excessive shrimp density. This operation process is indispensable especially in the season when the temperature is high. Third, during the season when the temperature is relatively low, the water does not normally need to be changed during the season. It is only necessary to make up for the water overflowing from the mouth of the tank cover on the way to the bumps on the way. In seasons with higher temperatures, in addition to the overflowing water, the length of the road can be considered. It is better to change one or two new waters. When replacing new water, do not replace water in tap water and contaminated rivers, lakes, etc., and replace well water. In addition, before loading shrimp, two aerobic pumps and power must be checked and tested. Only when the safety and reliability is confirmed can the shrimp be shipped; the power operation is normal and the aeration pump is oxygenated. Problems, stop the inspection in time, and start another oxygen pump at the same time.
