Why do Australian dragons grow slowly?

Because the ambient temperature is too high, the most suitable water temperature for crayfish growth is between 18 and 36 degrees. When the water temperature exceeds this range, including below 18 degrees and above 36 degrees, the growth rate of crayfish will obviously slow down.

Although the metabolism of crayfish will be faster in high temperature season, it should grow faster, but don't ignore a basic common sense at this time. That is, crayfish is a common typical crustacean, and its growth is accompanied by molting. When molting is hindered, growth will stagnate. Therefore, it is very important to ensure the safe molting of crayfish.

Many times, farmers ignore the daily management of patrol ponds, which leads to many management measures not being done well enough, including water level regulation and water quality improvement. In high temperature season, the water body is eutrophic and the water level is too shallow. If water is not replenished in time, crayfish shells will harden in advance or attach many organic pollutants to the shell surface, which will increase the difficulty of molting and reduce the molting efficiency. At the same time, the eutrophic water lacks oxygen, and there are many harmful bacteria and parasites, which objectively increases the popularity of crayfish. Natural crayfish will grow slowly because of stress response and self-protection instinct.
