Key Techniques for Reducing the Casualties of Parental Fish
The main factors leading to the death and injury of spawning parent fish are as follows: one is that the parent fish consumes a lot of physical energy in the process of spawning and reproduction, and the side effects of spawning drugs make the resistance ability of the parent fish decrease. If the fish body is injured, the pathogen infection is easy to cause diseases; the other is that the parent fish is poor in constitution, or the water temperature changes greatly during spawning, and the dosage of spawning drugs is improper. The parent fish cannot spawn normally, and thus causes its own physiological activity disorder and death. Therefore, in production, it is necessary to effectively grasp the prenatal cultivation of parent fish, so that the gonad development of parent fish is normal.

Prevention and treatment of lung choking in turtles
Tortoises are divided into dry turtles, aquatic turtles and semi-aquatic turtles. Dry turtles live on land or mountain areas all the year round. Aquatic turtles live in rivers, lakes, ditches, streams and farmland. Semi-aquatic turtles live in the environment where water and land meet all the year round. Under natural conditions, turtles are not easy to choke water or suffocate and die, but under artificial breeding conditions, due to different species or environmental conditions, or artificial improper ways to cause turtle lungs to choke water and die, but sometimes occur in farms. 1. Reasons for choking water 1. Artificial breeding ponds are often small, if the water quality deteriorates
