The use of nylon bags for oxygenation transportation is the most extensive, and the more suitable transportation specifications are about 3 cm for summer flower fingerlings; Large-sized fingerlings are transported with special rubber bags for oxygenation. The specifications of commonly used nylon bags are 70 cm 40 cm 40 cm, generally holding 25% 30% of water, 70% of oxygen, and the density of each bag can be shipped according to the size of the seedling, the temperature and the length of transportation time. The water temperature is 25, the journey is 20 hours, and it can hold 10,000 fish fry below 1 cm; cm fry 3500 5000; There are 1500 2000 summer flowers of about 3 cm, and the survival rate is more than 95%.
The transportation time should not exceed 24 hours, and the mouth of the bag should be solid with a rubber band after oxygenation. After the fish arrives at the destination, the nylon bag is unloaded first, placed in a cool place for 10 15 minutes, and then put into the breeding pond water, and continue to splash water manually, about 10 minutes and then open the oxygenation bag, and gradually pour into the breeding pond water, when the packaging water and the water temperature of the breeding pond is basically the same, and then put the seedlings into the breeding pond.
-
Sufficient oxygen transport in plastic bags. Three or five days is no problem.
-
In addition, it should be noted that the amount of water added to the plastic bag should not exceed one-third, and the oxygen added should be twice the amount of water filled. To arrive at the airport delivery office 3 hours before the flight's departure. Inquire 028-85015545 13088072501

The success of air frying is directly related to the survival rate of fish fry, so it is necessary to do a good job in every link during transportation to ensure success, and the following aspects need to be paid attention to.
1. Stop eating: If it is the fry that has just opened by air, do not need to consider this problem, if it is the fry that has been opened for a period of time by air, you should pay attention to this problem, the fasting time is at least 1 day or more, generally 2-3 days, so as to ensure that the feces in the fry are fully discharged from the body, so as not to pollute the water quality in the plastic bag.
2. Exercise: This problem is also for the fry that have opened for a period of time, the fry that have just opened do not need to consider the problem, under normal circumstances, if the fry that have opened for a period of time can be exercised by means such as pulling nets before air transportation, the survival rate will have a very good effect during transportation.
3, cooling: the cooling here includes two aspects of cooling, one refers to the conditional situation in advance in the aquaculture water cooling, under normal circumstances within 2 days before air transport, the aquaculture water body can be cooled down 3-5, the second refers to the cooling of the water body in the plastic bag when packing, at this time can be reduced on the basis of the aquaculture water body 3-5.
5. Packaging: Fish fry packaging generally has special plastic bags, these plastic bags are double-layered, if there is no special plastic bag, pay attention to the use of double-layer plastic bags when packing, to ensure safety; If the transportation time is long, consider using a foam box, and add ice packs to the foam box to ensure that the water temperature does not rise.
6. Quarantine certificate: inspection and quarantine certificate is required for air transportation, which needs to be handled locally.

The use of nylon bags for oxygenation transportation is the most extensive, and the more suitable transportation specifications are about 3 cm for the Charchai finchfish fingerlings; Large-sized fingerlings are transported with special rubber bags for oxygenation. The specification of the commonly used nylon bag is 70 cm x 40 cm x 40 cm, generally holding 25% 30% of water, 70% of oxygen, and the density of each bag can be shipped according to the size of the seedling, the temperature and the length of the transportation time. Water temperature 25'c, 20 hours of transportation, can be loaded with 10,000 fish fry below 1 cm; cm fry 3500 5000; There are 1500 2000 summer flowers of about 3 cm, and the survival rate is more than 95%.
The transportation time should not exceed 24 hours, and the mouth of the bag should be solid with a rubber band after oxygenation. After the fish arrives at the destination, the nylon bag is unloaded first, and it is temporarily stored in a cool place for 10 to 15 minutes, and then it is released into the water of the human breeding pond, and the water is constantly drenched with artificial water. About 10 minutes to open the oxygenation bag, and gradually irrigate the water of the breeding pond, when the packaging water and the water temperature of the breeding pond is basically the same, and then put the seedlings into the breeding field.
-
The water temperature is 20 to 24 degrees Celsius, it can be transported for 15 24 hours, and the survival rate is high.
After arranging the time and density, special attention should be paid to:
Nylon bags are not mixed with aquatic organisms, especially aquatic animals;
It is required to avoid strong vibration and bumps as much as possible during the transportation of fry;
It is necessary to prevent the water temperature from changing too much and too quickly;
Prepare several empty bags and fill them with oxygen, and check whether there is air and water leakage frequently during transportation, and if there is a occurrence, it is necessary to repair or replace the bag in time.

1. Newborn small fry should be raised separately from the big fish immediately to avoid being eaten by the big fish. Newborn baby tropical fish should master feeding and changing the water, do not feed on the first day, and feed the next day. Water temperature is very critical to the growth and development of tropical fish, the suitable temperature should be around 25-28 degrees, small fish generally like old water, as long as it is not too turbid do not change too diligently, feed 2 3 times a day, each time to eat within 20 minutes is better. >>>More

If the silk thread can be distinguished by fire, silk and chemical fiber can be distinguished, but if it is a fabric, it will take a lot of trouble to distinguish whether it is silk or chemical fiber silk, because now it is necessary to compound silk with other fiber silk (yarn) to change the defects of silk fabric.
