I. Physical factors
The physical factors that cause dragon fish to get sick mainly refer to temperature. Generally speaking, within a certain range, the higher the temperature, the faster the reproduction rate of pathogens, which leads to an increase in the incidence of dragon fish, except for some species of pathogens that like to live at low temperature, such as water molds, prototype melon insects and small punctate Bacteria such as Pseudomonas bacillus.
Second, chemical factors
For fish living in water, the quality of water quality is the main factor that causes them to get sick, and the quality of water quality is determined by the chemical factors in the water. indicators are based. As far as arowana breeding is concerned, the water quality should meet the following requirements: the dissolved oxygen in the fish tank
is above 4mg/l; the pH value is maintained between 7.5 and 8.5; the ammonia nitrogen content is less than 0.2mg/l. In such a rearing environment, the incidence of dragon fish is relatively low, and vice versa.
III. Biological factors
Biological factors are closely related to the incidence of fish diseases, that is, plankton and pathogenic organisms in water. If there are a lot of plankton in the water, the water quality is easy to age, and the arowana lives in this water quality, and its disease rate will be very high. In addition, if the content of pathogenic organisms in the water is high, the chances of the arowana being infected will be greatly increased, and then it will be easy to get sick.
4. Human factors
Some arowanas growing in their native places rarely get sick in their lifetime. Why change the environment and raise arowanas in the fish tank, their chances of getting sick are greatly increased? The reason for this situation is inseparable from the influence of factors, among which the influence of human factors mainly includes:
1. The high stocking density of fish tanks and excessive feeding due to subjective factors, etc. ;
2. The food fed is unclean or spoiled, bringing foreign pathogens and parasites to the arowana in the aquarium, thereby causing the arowana to become infected and sick;
3 , The feeding operation is inappropriate. For example, in the process of catching fish and changing tanks, the body surface of the arowana was damaged due to carelessness or impatientness. At the same time, whether the corresponding disinfection work was done well, which in turn caused saprolegnia or bacterial disease of the arowana.
The above summary of the four influencing factors that lead to Arowana disease, I hope pet owners can strictly do a good job of feeding and management from the above four aspects, so as to improve the quality of life. Reduce dragon fish disease.
