Precautions when hatching fish eggs
The fish eggs in the water, like the eggs on the land, are rich in nutrients and easily become the food of many aquatic animals, and are vulnerable to attack and mutilation. For example, small fish and shrimp in the water are the main killers of damaging fish eggs, and even large-scale zooplankton species such as various insects in the water and large otters can harm fish eggs. Therefore, we must pay attention to eliminating the enemies of fish eggs. Strictly clear the pond and filter it when entering the water.
During the incubation process, keep the oxygen in the water body rich. During the development of embryos, oxygen needs to be breathed. After the emergence of tail buds, a large amount of oxygen is needed. During larval stage, more oxygen is needed. Whether the indoor dry hatch or outdoor pool hatch should pay attention to the supply of sufficient oxygen. When hatching in the pool, it is best to increase the micro-flowing water, impulse the fish's nest, and increase the flow of oxygen.
During hatching, we must pay attention to the quality of incubating water, keep the water fresh, and use contaminated water and toxic water.
During the hatching process of the fish eggs, if the water body is not well disinfected and the injuriousness is not complete, the water mold will reappear and the water will produce watery mold on the eggs, which will kill the fish eggs. Therefore, during the incubation process, the eggs must be disinfected first. One millionth of malachite green (or a malachite greenish green solution) is used to soak fish nests for 10 minutes to kill the water mold. It must be pointed out that malachite green is a carcinogen and it is better not to use it. It is recommended to use salted water, a solution with a concentration of 3% to 5%, and after 3 to 5 minutes of soaking the fish nest, place the fish nest in water or on an indoor shelf for incubation.
In order to thoroughly sterilize and incubate the incubating environment and avoid the predators of fish eggs during the incubation process, every aspect of disinfection should be strictly controlled. That is, fish pond disinfection, water disinfection, fish nest disinfection, non-poisonous harmless water shower ... ... must not be careless.
One fish egg and one seedling, each egg has high nutrition;
More than it wants to taste, the enemy is like a cow.
Disinfection is very important, every link can not be less;
If you let off an enemy, how much damage to the fry!
