1. Be sure to make three advances.
You must know the details of your supplier's fish half a month in advance. (2) Tell the other party to do a good job of fish inspection one week in advance; Check whether the fish is healthy and do a good job in online training. (3) Stop eating two days in advance to keep the fish on an empty stomach during transportation.
2. Before installation, it is necessary to "touch two and see three incisions". ① Check whether the surface of fish is smooth, and it is difficult to transport if there is too little or no mucus. ② Second, see whether the surface color of the fish is normal and shiny, whether the fish has scales, rotten fins, erythema and scratches, whether the tail fin edge is angular, whether the eyes are crystal clear, and whether there are bumps or depressions; Whether the abdomen is swollen, etc. None of the above points is suitable for transportation. ③ Three laparotomies were performed, and 2 ~ 3 fish were randomly selected for laparotomy to observe whether there was feed in the intestine and whether there were lesions in the internal organs.
3. Drug prevention should be done well. The stimulation of transportation stress will lead to the damage of liver and other tissues of cultured fish, resulting in irreversible physiological changes of the body, thus accelerating the death of fish and making the transportation of cultured fish difficult. Healthy constitution is the basis of improving the ability of fish to resist transportation stress, including intestinal regulation and hepatobiliary regulation. Bile acids protect the liver and gallbladder of cultured fish, thus promoting the overall health of fish.
4. Pay attention when loading.
(1) The fish tank should be oxygenated with water. The water quality of the transport fish tank should be pollution-free and the water temperature should not be too high (it can be adjusted with ice cubes, but the ice cubes should not be directly put into the tank. Large size oxygen bags can be used to avoid direct contact with fish and frostbite. ) turn on the oxygen and check whether the oxygen is normal; When loading fish, the oxygen is slightly higher than normal, and then it is adjusted to the normal range when driving. When the work is done, you can load the fish.
(2) Operation with water, because grass carp is quick-thinking and good at jumping. It is not easy to weigh the fish out of the water, and the fish will fall off scales or scratch during the struggle, which will affect the appearance.
(3) Order of feeding boxes: In the process of feeding boxes, do not put the fish in one box at a time, but gradually increase it to a reasonable density in batches.
(4) Transportation density: 60% of the volume of the fish box is packed in the box. For example, the volume of the fish box is 1 m3, which can hold 600 kilograms of grass carp.
(5) the specifications are matched, and it is not easy to mix codes. The difference of specifications is not easy to exceed 1kg/ tail, so as to avoid the small-scale injury caused by the agitation of large-scale fish.
Inspection during transportation.
1. Check whether the oxygen is normal, generally once every 65438 0.5 hours. Too much oxygen will make the fish excited and hit the box, and too little oxygen will lead to hypoxia and suffocation.
2. Check whether the water temperature rises and add ice cubes reasonably according to the actual situation.
3. Check whether the water quality changes and change the water in time.
4. Check whether there are dead fish, remove them in time, find out the reasons and take appropriate measures.
When uninstalling, you should also do the following
1. The water in the fish tank is clear and pollution-free, and the water temperature is lower than the water tank in the transport vehicle.
2. When unloading fish, turn off the oxygen on the fish car 20 minutes in advance, so that the fish in the box are in an anoxic state. This can prevent the fish from jumping and getting injured when fishing. When the fish is moved into the detention box, it should be fully oxygenated in time.
Summarize and analyze
Although the long-distance transportation of live fish is very risky, as long as we pay attention to every small detail, we will certainly succeed. Remind most live fish transporters that it is better to pull less than Dora, and less than Dora. Only fish with good quality can improve the survival rate of transportation, which is the market demand.
