During the winter and spring, especially during the Spring Festival, the market demand for fresh aquatic products has soared. For farmers who have visions, timely trafficking of fresh and live aquatic products will be an ideal road to prosperity. Here are some of the major live freshwater products for long-distance transport preservation and preservation technology for reference.
Live fish can be transported with plastic film (better with wooden barrels) on the bottom and around the wooden box. To reduce the number of deaths on the road, fish that are not flexible enough to have mechanical trauma should be removed before shipment. At the same time, a nylon net cover should be placed over the wooden box to prevent live fish from jumping out of the water or falling out of the car. If sleeping methods are used for long-distance transportation, the effect will be better. The method is to inject 50% each of carbon dioxide and oxygen into the water. After the fish is in a coma, the fish is put out and put into a plastic bag or a box or a box for transportation. This will allow them to sleep for 30 to 40 hours. Once you reach your destination, put it in clear water and it will take only a few minutes for the fish to wake up.
Trafficking of river crabs can be transported in short-distance traffic with wet and permeable Po. It should be avoided during transportation. Long-distance transportation should be carried out with strict storage. First, lay a layer of mud on the bottom of the loquat, and put some sesame or scattered eggs. , and then live crabs will only be stacked flat, and then covered with shade. If you put some absorbent sponge or foam in the crab, the effect will be better. Because crabs are afraid of the wind, they must use windbreaks or sacks to protect the wind during transit.
Turtles trafficking in turtles is much easier than live fish. However, for the acquisition of the soft-shelled turtle must be strictly examined, only the appearance of a complete, lively, flexible throat rotation, the turtle will be able to quickly turn over when the abdomen in order to maintain a high survival rate. Before transport, it is best to stop for a few days so as to reduce excretion. In the course of transportation, turtles and transportation tools should be cleaned every few days to remove the excreted secretion of turtles. Turtles have a habit of biting each other and should not be intensive together for a long time. In the shallow bamboo baskets and wooden boxes, the interior of the wooden box can be divided into several small communities. Only one soft-shelled turtle is placed in each plot, and a layer of aquatic plants is laid on the bottom of the soft-shelled turtle. Several vent holes must be left around the wall to avoid the turtle. Suffocated by lack of oxygen. Pay attention to regular water supply during transportation to keep its housing moist.
Astragalus trafficked Astragalus to have a very strong oxygen tolerance, which is extremely beneficial to long and short distance transportation. Firstly, the captured water eels should be stored in water tanks, casks or concrete pools, but do not put them in containers that contain oil. After a few days of stocking, the waste in the body is basically drained and shipped out. After several hours of short-distance transportation, fully wet the fish with water and put it in a bucket or canvas basket (in a container capable of holding 50 kg, put about 20 kg of jaundice). During transportation, it must be poured into water to keep it in shape. The table is humid; long-distance traffic is due to high density, low dissolved oxygen, combined with the intertwining of fish, poor mobility and breathability, it is easy to cause fever, lack of oxygen in the corpus callosum. To do this, we must change the water once a day - 2 times, every 24 hours to put penicillin (in a dose of 300,000 units per 25 kilograms of water) to prevent the fever "jaundice", but also in every 50 kg of jaundice into 1 Kilograms - 1.5 kilograms of loach, the use of loach active habits, so that they swim up and down in the container, can avoid intertwined jaundice, but also improve the internal ventilation of the container, and then improve the survival rate of squid transport.
Mud-carrying for short-distance transport within a few hours can be used to enclose mud or mud on the surface of the loach, keep the skin moist, and then transport it in barrels and other containers for transport; if long-distance trafficking, double-layer nylon membrane should be used to inflate. For transport, add a small amount of water or ice to each 6cm-120cm nylon bag, and then fill 10kg of muddy stuff and fill with enough oxygen to fasten the bag with a string or rubber band. Finally, put the bag into the hard You can leave the carton for transportation. Casks can also be used for shipping. The injected clean water should go beyond the fish body, then add a small amount of ginger and scattered eggs, and change the water at the proper time. This can ensure multi-day transportation.
