Skills in the use of fish medicine
After the disease, the food intake of aquatic animals is generally reduced, often wandering alone or climbing onto the shore and among aquatic plants. For the groups of aquatic animals with severe loss of appetite, even if the drugs are mixed in the feed, only some aquatic animals that have not lost their feeding ability can eat the bait, so it is difficult to achieve the goal of comprehensive drug treatment. When using the method of drug bait feeding, the food intake of sick aquatic animals must be fully considered. The author advocates that the bait should be prepared according to the actual food intake of aquatic animals during the disease period.

The breeding of soft-shelled turtle seedlings should be fed scientifically.
The breeding of soft-shelled turtles. Whether scientific feeding can be carried out is the key to affect the growth and quality of soft-shelled turtle seedlings. Therefore, the scientific feeding of soft-shelled turtle seedlings is introduced for reference and application. Like other aquatic animals, baiting can be based on four principles, namely, quality, quantity, timing and positioning. However, the four contents of breeding and feeding of soft-shelled turtle seedlings have their own characteristics. In the process of growth, soft-shelled turtle seedlings not only accumulate energy and increase body weight, but also provide various nutrients and nutrients for the growth and development of various functional organs in the body.

What should be paid attention to in the construction of eel ponds on the roof?
What should be paid attention to in the construction of eel ponds on the roof? Considering the bearing capacity of the roof, it is suggested that all the roof ponds should be built with bricks (the wall thickness is 6 cm); except for the breeding ponds, soilless culture should be adopted. From the point of view of cooling, a wall often illuminated by the sun should be raised to exceed the height of the culture pond, and then about 10 cm should be retreated to begin to build the pool, so as to prevent the sun shining on the pool wall for a long time, causing the water temperature of the pool to rise abnormally than that of other ponds, causing the imperceptible high temperature of the pool water and causing Monopterus Albus to die.
