鱼苗运输方法（Fry transport method） Fry transport method.Txt as long as you want, as long as I have, you still turn around what ah, honest, stay with me on the line. Listen to me, ask why so much, I am on your side, you can go wrong! Follow me! I cant give you happiness is my fault, but who you are not happy, I TMD to chop him. Three main factors affecting the survival rate of fish and fingerling transport The transport survival rate of fish and fingerling is a highly technical work. It is important to understand the factors that affect the survival rate of fish and fingerling transportation and to prepare for transportation successfully. First, the main factors affecting the survival rate of fish transportation The density and survival rate of L and dissolved oxygen in water depend on the dissolved oxygen in water, and the oxygen consumption of fish is closely related to the dissolved oxygen in water. In order to improve the survival rate of fish transport, it is necessary to increase the amount of dissolved oxygen in water by water hammer, water exchange or oxygen feeding method. On the other hand, the individual fish should be transported as much as possible. In order to reduce the oxygen consumption during fish transportation, drug anesthesia can be used to reduce the metabolic intensity and oxygen consumption of fry and fingerling. In the absence of new water or the lack of other aerobic equipment, fish and fish can also be transported by chemical aeration to increase dissolved oxygen in water. The common oxidant has the best effect with two sulfate, which immediately decomposes with oxygen and emits oxygen, with a concentration of 1-50mg/L. 2, water temperature and water temperature influence two: first, the higher the water temperature, the less dissolved oxygen in water; two, the higher the water temperature, fish activity and ability and metabolism is stronger, then the greater the oxygen consumption of fish. Therefore, we should try to select the low temperature
