the transportation methods of live seafood should be adapted to local conditions, mainly dry and wet, which can be summarized as follows. When the live fish is transported in barbiturate solution of 7× 11e-6 ~ 13× 11e-6, the belly of the fish will face upwards, and it can be anesthetized for about 11 hours at the water temperature of 11℃. The transportation methods of live seafood should be adapted to local conditions, mainly dry and wet, which can be summarized as follows. You don't have to look at the dry method! 1. Dry transportation, also known as waterless transportation, is to cool the water to the temperature that makes the fish and shrimp suspend their life activities, then dehydrate and transport it. After reaching the destination, put the fish and shrimp into the water, and they will wake up again. In the dehydrated state, its life can last for more than 24 hours. This transportation method not only greatly improves the freshness of fish and shrimp, but also saves freight, so it is an ideal transportation method. Such as Japanese prawns, swimming crabs and lobsters, can be transported in wooden cardboard boxes or foam boxes. For details, see the section "Live transport of lobsters". 2. Water spraying transportation is suitable for mussels, scallops, meretrix meretrix, oysters, blue crabs, etc., and seawater should be regularly observed and sprayed during transportation. 3. Canvas barrels are transported by sewing canvas into canvas barrels, the bottom of which is mostly square and a few are round, and its length and height can be determined according to the transport quantity and vehicle volume, generally 1.8 ~ 1.2m.. After it is made, it is coated with paraffin wax and supported by an iron frame. The quantity of shipment can be determined according to the individual size of fish and shrimp, the temperature of water, the length of transportation time and other conditions. Generally, about 111kg of fish can be loaded per ton of water. It can be transported by train, car, carriage or ship. On the way, the oxygen is supplemented by changing water, and the quality of the changed water must be treated in advance to avoid accidents. Generally, the journey can last for 6 days. If the bucket is often inflated or oxygenated, the journey will be longer. This method is safe, but the cost of equipment is slightly higher. If the survival rate is high, it is quite cost-effective. 4. Packaging and transportation in plastic bags: firstly, sterilize the live fish and shrimp, put the prepared water in the plastic bags, then put the fish and shrimp in different specifications and quantities, then squeeze out the air in the bags, and inject an appropriate amount of oxygen, and fasten the bag mouth with a rubber band. Then put plastic bags into paper boxes, each box can hold 1 ~ 2 bags, preferably in foam boxes. When the temperature is high in summer, you can put a small bag of ice cubes in the box to cool down. This method is widely used all over the world at present, with a high safety factor. 5. Frozen transport adopts special frozen transport boxes to transport live fish. Generally, the heat insulation monster of transport box is made of polyurethane board with a thickness of 21cm, made of stainless steel, injected with about 111L seawater and 91L water, and then put 811L fish and 91L ice into the box. Before closing the box mouth, add 31L ice. 6. Drug Transportation Method (1)MS-222 Anesthesia Transportation Method Live fish are transported by MS-222 (ethyl alkyl sulfonate m-aminobenzoate) solution with a concentration of 1.2× 11e-6 ~ 1× 11e-6, and live fish can be transported for more than 41 hours after anesthesia. After arriving at the destination, live fish will wake up quickly when put into the pool. (2) The live fish were transported in 511×11E-6 carbonic acid aqueous solution for 1 ~ 2 days by carbonated water transportation method, and the survival rate was over 91%. (3) Ether anesthesia transportation method Pour ether (2 ~ 3 ml per kilogram of live fish) on cotton, wet cloth, aquatic plants, etc., and stuff it into the mouth of live fish. After 2 ~ 3 minutes, the fish will be in a coma, and then put it into a canvas bucket container filled with clear water for transportation, which can be anesthetized for 2 ~ 3 hours at a time. This method is simple and feasible, and is suitable for short-distance transportation. (4) Quinadine solution transport method can transport the live fish after anesthesia with 1/211,111 ~ 1/11111 Quinadine aqueous solution or 1.1% ~ 1.4% Ullaitan aqueous solution. (5) Barbiturate transport method: The live fish will be transported in 7× 11e-6 ~ 13× 11e-6 barbiturate solution, and the belly of the fish will face upwards, and it can be anesthetized for about 11 hours at the water temperature of 11℃. After arriving at the destination, the fish can wake up in 5 ~ 11 minutes after being put into an aquarium or fish pond. If larger fish are transported, injecting 1.1mg barbital sodium per kilogram of live fish can anesthetize the fish for 11 ~ 12 hours. If it is found that the breathing of live fish in water is extremely weak after injection, intramuscular injection of nikethamide or caffeine sodium tea should be carried out quickly, and each fish should be injected with 1ml of 25% liquid medicine. If the live fish still jumps and collides after injection of anesthetic, the liquid medicine should be replenished until it is anesthetized. The above use of drug treatment for anesthesia transportation depends on the specific situation of each place and the source of drugs. 1. Transportation of fresh fish includes live transportation of famous and special fish such as eel, osmanthus fish, Canadian perch, pike tail fish, etc. The main operation methods are as follows: firstly, the fish caught on the market are temporarily raised in a cage or a cement pool at high density, and washed with a high-pressure water gun for 1-2 hours, so as to eliminate the feces in the body, and then the old, the weak, the sick and the disabled are removed. Before packing and shipping, the fish are temporarily raised in ice water at a low temperature of 11-14℃ for 2-3 hours. Make it stop or weaken the effect of new metabolism, breathe and move slowly, then pick it up and weigh it and put it into plastic bags. Each bag contains 71% fish and 31% ice water. After being oxygenated, it is tightly tied with a rubber band, then put it into a carton, and it can be shipped after being tightly tied with a thin nylon thread. This transportation method of low-temperature anesthesia usually takes 1.5 ~ 21 hours to reach the destination, and the survival rate can reach more than 98%. However, from catching, soaking at low temperature, packing, inflating, loading and unloading, and starting, the operation should be continuous, and the sooner the better, the better. However, it is hot in summer and autumn, so an ice pack should be placed around and in the middle of the carton to reduce the temperature in the carton to an appropriate temperature, and at the same time, prevent the plastic bag and ice pack from leaking and causing the accident of broken boxes and dead fish. In this way, after arriving at the destination, it only takes a few minutes for the fish to be awake and move normally. Second, in the process of long-distance transportation of fish and shrimp, aquatic products companies often add a proper amount of calcium peroxide solid in water to ensure the survival of fish and shrimp for a long time. Third, in the general transportation method, you can use the "catfish effect". It takes a long time for fishermen to go out to sea to fish, so when they returned to the port, they found that all the sardines they caught were dead. And there is a fisherman whose sardines are still alive after arriving at the port, so he can sell them at a good price every time. The reason is that he put several catfish in sardines. Catfish are active by nature and move back and forth among sardines. In this way, those sardines always have a sense of crisis, that is, they can stay alert, so they are still alive at the port. In the past, when transporting fish, it was easy for fish to die. Later, after putting a few catfish in the tank, the mortality rate of fish decreased. It shows that there is competition to develop. Long-distance transportation of live shrimps includes plastic bag oxygenation method, canvas basket method and living water boat method. The three transportation methods have their own advantages and disadvantages. Plastic bags filled with oxygen have high survival rate, but the operation is complicated and the cost is high. If you transport 1,111 kilograms of live shrimp, you need at least about 1,111 plastic bags and more than 511 cartons. And the durability of plastic bags and cartons is poor, especially cartons are all scrapped once or twice. The number of shrimp transported by canvas basket is small, and if the journey is more than 111 kilometers, the survival rate is low. It takes a long time to transport by running water boat, and the water quality on the way changes greatly. The above three transportation methods are suitable for areas with low output of green shrimps or for transporting parent shrimps and young shrimps, but they are not suitable for yugan county, which is located near Poyang Lake and has an annual output of more than 1,111 tons of green shrimps and needs to be transported all year round. In recent years, shrimp merchants in our county have used a method of transporting live shrimp in a combination of shrimp boxes. In this method, firstly, a large number of shrimps are transported, such as a 2-ton shrimp box, with a shrimp transport capacity of 411-611 kg each time and a 5-ton shrimp transport capacity of 1111-1511 kg each time; Second, the trip is long and the survival rate is high. For example, the trip from yugan county to Hangzhou is 611 kilometers, and the trial run from Hunan to Hangzhou is 1311 kilometers. The survival rate is as high as 81%-91%. Third, transportation is not limited by seasons, and it can be transported in high temperature season or low temperature season; Fourth, it is convenient to operate and manage; Fifth, the cost is low, and it can be used for at least 3 years with one investment. The shrimp box combination and shipping method are introduced as follows: 1. Box combination shrimp box combination transportation live shrimp includes shrimp box, oxygen increasing system, power system and shrimp collecting box. As a whole, it is used together with freight trucks, and the tonnage of supporting trucks is different according to the tonnage size. 1. shrimp box. Shrimp boxes are of 5, 3, 2 and tons in size. It is made of welded iron plate with a thickness of 3-4 mm and has a box cover. The thickness of the iron plate at the bottom of the shrimp box is 4mm, and the thickness of the iron plate at the box wall, the upper part of the box and the box cover is 3 mm. There is a drain hole at the bottom corner of the box. The front of the shrimp box and the inside of the box are provided with pipes of an oxygen increasing system. The shrimp box is installed in the middle and slightly at the front end of the truck box with thick iron wire or steel cable. 2. Oxygen increasing and power system. The oxygenation system consists of an oxygenation pump, a hollow iron pipe with a diameter of 51mm, a tap water pipe with a diameter of 15mm, two gate valves and corresponding rubber pipes. Each shrimp box is equipped with two oxygen-increasing pumps, and two oxygen-increasing pumps are equipped with two 6-12 horsepower power. An oxygen-increasing pump and a power are installed on the same base, and the oxygen-increasing pump is dragged by a belt to run. Installed in the front end of the shrimp box in the trunk of the long car, with one on each side. 3. Shrimp box. The shrimp collecting box is made of steel bars with a diameter of 6mm, No.8 iron wire and knotless mesh. The steel bar is used as a box frame with a volume of 85×41×11cm. The shrimp mouth of the shrimp collecting box is located at the wide side of the box. According to the tonnage size of shrimp boxes, a certain number of shrimp collection boxes, such as 5-tonnage shrimp boxes, should be equipped with more than 151 shrimp collection boxes. Second, the method of shipment of shrimp 1. Quantity of shrimp shipped. Depending on the tonnage size and season, the number of shrimps loaded is different. In late autumn, winter and spring, the temperature is low, and the 5-ton shrimp box carries 1,511 kilograms of live shrimp each time; In late spring, summer and mid-autumn, the temperature is high, and the 5-ton shrimp box carries 1111 kilograms of live shrimp. The number of live shrimps shipped in other tonnage shrimp boxes is converted by the tonnage of 5 tonnage shrimp. 2. Packing method. After the dirt in the shrimp box is removed, clean water is injected, and the amount of water injected is subject to the operation of people in it, and the oxygen-increasing pump is started to increase oxygen: then, the shrimps that have been temporarily raised for 1-3 days are put into shrimp collection boxes, each shrimp collection box has a volume of 85×41×11cm and contains 11 kilograms of shrimps, and the mouth of the shrimp collection box is tightly tied so that the shrimps cannot climb out. Immediately put the shrimp collecting box with shrimps flat in the shrimp box. When the first floor of the shrimp box is full, then put the second and third floors, and so on. After the shrimp box is loaded to the transported quantity, fill it with water, cover the box cover and start shipping immediately. In the process of packing, it is required to move briskly and work with water. The water in the shrimp box must submerge the shrimp collection box. If the water is not submerged, the shrimp collection box should be put after water injection. In this way, there will be no death due to lack of oxygen due to excessive shrimp density. This operation process is indispensable, especially in the high temperature season. Third, manage the low-temperature season on the way, and generally do not need to change water on the way, just make up for the water that overflows from the lid of the truck due to bumps on the way; In the high temperature season, it is better to replace the spilled water with fresh water once or twice, depending on the length of the journey. When replacing new water, do not replace tap water and water in polluted rivers, lakes and other waters, but replace well water. In addition, before loading shrimp, two oxygen pumps and power must be inspected and tested, and the shrimp can be loaded and shipped only after it is safe and reliable. On the way, we should also pay attention to whether the power runs normally and whether the oxygen pump increases oxygen. If there is any problem, stop the machine in time for inspection and start another oxygen pump at the same time. Transportation of commercial adult shrimps and live shrimps It is difficult to transport a large number of commercial shrimps alive, because the shrimp is thin in shell and does not tolerate low dissolved oxygen, and it is easy to die and deteriorate the water quality during transportation, which affects the survival of other live shrimps. However, with the continuous development of the aquatic product circulation market, the market price determines that the listed commercial shrimps must be kept alive first, and the majority of shrimp farmers and sellers are faced with the problem of how to transport live shrimps in batches. In recent years, Xiaxin Fishing Ground in Huangmei County, Hubei Province has explored a transportation method, which can be used as a reference: fresh shrimps are transported to the market, and agricultural transport vehicles are usually used to carry 1 ~ 2 water transport boxes. Because the live shrimps can't be transported in heaps, several small boxes are arranged in three compartments in the big box, and the survival rate of the transported shrimps is generally above 95%. Manufacturing materials of water-carrying transport box: high-quality Chinese fir, angle iron, rings, etc. are selected, and the thickness of Chinese fir board is 3 cm. The size of the big box is: 171cm× 111cm× 132cm. Use 51 mm× 51 mm angle steel to weld the upper, middle and bottom parts into a frame, and use screws to reinforce the hoop. There are two circular rings in front and back of the box body, which are transported with ropes, and then a water outlet valve is installed in one corner of the box. Small boxes containing shrimps are placed in the big boxes, and the materials for making the small boxes are still high-quality Chinese fir, polyethylene cloth, plastic packaging bags and nails. The size of the small box is 96 cm× 51 cm× 11 cm. Chinese fir is used as the frame, polyethylene cloth is used as the cover, and the plastic packaging bag is tightened and fixed with nails, and the burrs are pressed tightly. During transportation, live shrimps with the same body shape and no injury are selected, and each shipment depends on the weather, season and water temperature, and edible well water or pollution-free river clean water is used. Generally, each large box contains about 211 kilograms, and the suitable water temperature in the box is 6 ~ 8℃. If it exceeds 11℃, ice cubes must be placed in the box to reduce the water temperature. Generally speaking, MPQ series diaphragm air compressors are selected for oxygen enrichment, model: 915, power 91W, voltage 12V, displacement 111L/min, and power supply can be DC or AC. Generally, the price of three air compressor cars outside each large box is unknown, because the car prices vary from place to place, and it will be decided according to the car condition.
