Safe Transportation of Live Fish Act
Sealed transport: sealed transport transports fish and water in sealed and oxygenated containers. The utility model is characterized by small volume, convenient transportation and general adult fish transportation. within 8 hours, there is no need to change water halfway, the sealing degree of shipment is high, and the survival rate is high. The fish fry can survive in the container for more than 20 hours at a time of oxygenation, which is more convenient for long-distance transportation of a large number of seedlings. plastic bag oxygenation and plastic bucket oxygenation can be used.
1. Sealed and oxygenated transportation of plastic bags: the plastic bags are filled with clean water, which accounts for 1 / 3 of the total capacity of the bags, and then load appropriate amount of fish fry or fry as planned. When transporting large-size fish species and adult fish, add penicillin powder (60,000 units in 10 kg) and discharge sufficient oxygen from the bag.
2. Oxygen-sealed transportation of plastic barrel: its advantage is that it is not easy to be damaged, does not need additional packaging, and is convenient to load and unload and can overlap. The plastic bucket is equipped with water inlet and outlet, injection and exhaust holes, using fashionable water 1x3-1tick 2, 25-liter plastic barrel, which can hold 8-100000 fish fry. If 5-100000 units of penicillin and streptomycin powder are added to the barrel and then oxygenated, the delivery time is less than 20 hours, and the survival rate can reach more than 95%.
Second, open transport: mainly in canvas boxes (buckets), canvas boxes (buckets) are supported by iron frames or wooden frames around, with a volume of about 1 cubic meter, using fashion water 3 times and 4 capacities. When the water temperature is 20-25 degrees Celsius, each box can contain 30-350000 fish fry, 2-25000 summer flower fingerlings, and 3000-4000 10 cm-long fish fry when the water temperature is 15 degrees Celsius. During transportation, you should constantly fill the air or hit the water with a water percussion board to increase the amount of dissolved oxygen in the water. If you find a fish floating head, change the water in time.
Long-distance transport of fish fry, the way to feed, usually 2 hours after the change of water, each box fed half a cooked egg yolk, 3 hours later, suck out the sediment, so as not to cause the death of fish fry caused by changes in water quality. If it is difficult to change water, the methods of percussion, air delivery and water leaching can be used to increase oxygen. Aeration time should not be too long, limited to non-floating head, such as oxygen delivery time is too long, fish fry top water, physical exertion is too large, but also easy to cause death.

[Ingredients] Knife fish, cooked pork fat, cooked ham slices, cooked ham powder, spring bamboo shoots, water mushroom, egg white, coriander powder, Shaoxing wine, refined salt, monosodium glutamate, onion knot, ginger slices, chicken clear soup, water starch, cooked lard. [Preparation process] Scratch the scales, remove the gills and fins of the swordfish, cut a knife horizontally outside the anus, insert bamboo chopsticks into the belly of the fish from the gills, wring off the internal organs, cut off the tip of the fish tail and wash, cut open the back of the fish one by one along both sides of the spine, remove the spine and skin.

It's good to put the fish in the box in autumn.
After fattening in the pond in autumn, the fish species are generally strong and easy to adapt to the cage environment. At the same time, when the caisson overwintered with large water surface, not only the body weight consumption of the fish species overwintering was less than that in the pond, but also the fish began to eat earlier after overwintering in spring, and the growth period was about one month longer than that of the fish in the box in spring. The growth rate of fish is faster and the yield is significantly increased. Compared with the species in the box in spring, the caisson overwintering species grow about 30% faster and the size out of the box is about 35% larger. Therefore, it is more scientific for fish to overwintering in the box in autumn.
