Feed Saving skills of Pelteobagrus fulvidraco
At present, Pelteobagrus fulvidraco is widely cultivated, and it is the main species to increase the income of agriculture and fishery in many places. However, in the process of culture, because of the one-sided pursuit of yield, many farmers do not know how to save feed and constantly put too much feed and fertilizer into the culture water, which not only increases the culture cost, but also deteriorates the water quality. affect the growth of Pelteobagrus fulvidraco, resulting in low culture efficiency. How to save feed cost in production practice? Strict cleaning, disinfection and disinfection of ponds can kill wild miscellaneous fish and reduce the number of people fighting for food.

How to choose and buy stone turtle seedlings
First, it is necessary to try to buy stone turtle seedlings with good physique and strong disease resistance, so that the probability of getting disease is low; if the turtle seedlings have poor physique and low disease resistance, the probability of getting disease is high. The physique of the turtle seedling depends on the quality of the turtle species. From the aspect of turtle species, the seedlings hatched by wild and imitation wild stone turtles have the best physique, strong growth and development ability and disease resistance, and the probability of getting disease is low. Therefore, try to buy the seedlings hatched by wild or imitating wild stone turtles. In reality, the wild

Restocking technology of fish species after rainstorm
Every year, some areas are hit by typhoons and torrential rains, resulting in the collapse of the ridges of fish ponds and serious escape from fish.

How to do well healthy aquaculture of aquatic fish
As the fishing proverb goes, "if you plant good seedlings, you will have high yields." When selecting and purchasing improved varieties, it is necessary to grasp the following points: ① knows the age and body weight of parent soft-shelled turtles from seedling donors, generally taking more than 1 kg of 2-year-old as normal parents, and 3-year-old 2-Mel 3 kg is more ideal. The ② is neat in specification. About 10 grams of juvenile soft-shelled turtles should be used to raise soft-shelled turtles, and about 100 grams of commercial soft-shelled turtles should be used to raise soft-shelled turtles. The weight difference between individuals should not be too big, so as not to compete for food and bite each other and affect survival and growth.

Why do marine crabs die in large numbers during shelling?
The death of marine crabs in the shelling period shows that a large number of marine crabs die before shelling (failed shelling), and many marine crabs die after shelling (too much physical consumption after shelling, soft shell does not harden, etc.). The causes of death of marine crabs during the shelling period are as follows: (1) the water body is polluted and the dissolved oxygen is low, which affects the shelling and leads to death; (2) the nutrition of marine crabs is unbalanced (lack of calcium, phosphorus, magnesium, zinc, iron, vitamins, etc.). Weak); (3) the use of irritant drugs during the shelling period, there will be some death; (4)

If you disinfect frequently, the aim is to kill the harmful bacteria, resulting in killing all the beneficial bacteria. In addition, after sterilization, we turned around and left the rabbit house with the sprayer on our back. after sterilization, the rabbits were reluctant to "take drugs" in the cage, which is likely to have side effects. According to mastery
