Analysis and Countermeasures of hypoxia in cultured Fish
Hypoxia refers to the state in which the internal tissues and cells of fish do not get enough oxygen to maintain their normal function. In order to distinguish from hypoxia in water, it can be called "biological hypoxia" or "tissue hypoxia". Asphyxia (dyspnea) is a phenomenon that occurs during biological hypoxia, and floating head is a common manifestation of dyspnea or asphyxia in aquaculture production. There are two cases of anoxic asphyxia in fish: one is that when the dissolved oxygen in the water is insufficient and the air pressure is too low, even if the respiratory function of the fish is normal, the tissues and cells in the body can not get enough oxygen, resulting in "anaerobic hypoxia";

Three elements of turtle hatching
The key to turtle breeding is to grasp the hatching of turtle eggs. No matter which hatching method is used, it is necessary to grasp the three elements of hatching temperature, humidity and air permeability. According to the hatching experiments of three-line closed-shell turtles, crocodile turtles, yellow-throated water turtles, eagle turtles and other turtles in recent years, as long as the temperature, humidity and air permeability reach the best state, the hatching rate of turtle eggs can reach 93%. 98%. 1. Hatching temperature the suitable hatching temperature of turtle eggs should be controlled at 28 ℃ ~ 35 ℃, and the best one is about 30 ℃. Not too high or too high.

Attention should be paid to the fishing of fish during the freezing period
The Spring Festival is approaching, which is an important period for the capture of aquatic products. Growing fish is mixed with the fish to be sold, so we should pay attention to the anti-freezing of fish species. Do not operate when there is freezing. Water should be added to ensure a depth of 1.5 to 2 meters to stabilize the temperature. Try to avoid exposing the fish to the air. Fish to be caught should be bathed in 2% salt water for 15 to 20 minutes to prevent water mildew. Where the eel is raised in the cage, the cage should be sunk to the bottom in time, come into contact with silt, and the box should be covered with straw to minimize operation and ensure safe overwintering.

Four Ways to Care for Fever Cattle
After drinking more water and fever, the cattle consume more nutrients, dry mouth, loss of appetite, resulting in anorexia. Therefore, water supply should be satisfied, otherwise it will aggravate the disease. To drink more water, to supplement body fluids, promote intestinal toxins discharged, in drinking water to add the right amount of sugar, salt is better. The cattle house should be kept clean and quiet for more rest, so that the sick cattle can rest more and reduce the muscle activity of the sick cattle, so as to reduce the consumption of physical strength and the generation of heat energy. Do not disturb sick cattle when sleeping. Better deep sleep can obviously enhance the immunity of cattle and improve resistance.
