Growth Cycle of Duobao Fish
Turbot, the scientific name of turbot, belongs to the flatfish family, commonly known as European flounder. It was called turbot in China. 1992 was introduced to China by Academician Lei Ji-lin of the Yellow Sea Fisheries Research Institute, and turbot was introduced to Huludao in 2000.
Because Duobao fish belongs to Nordic cold water fish, it requires extremely high culture environment and methods. The aquaculture water is natural well brine, which can not be recycled. The average annual water temperature of aquaculture can not exceed 20℃, and it can not be put on the market until it is fed with natural bait 12~24 months.
Generally, the breeding cycle of turbot is 9~ 12 months, while the growth rate of turbot in Xingcheng is slow due to the low water temperature, and the breeding cycle is as long as 18~24 months.
