Most common individuals are around 150 mm, and the maximum is 450 mm. Due to the extremely backward fishery production in the producing areas, the phenomenon of poison, electricity and explosion is very serious, resulting in a sharp decline in resources in densely populated areas below 1200m above sea level, and most of them are mature individuals, aged 2-3 years, and there are still a certain number of sparsely populated areas above 1200m above sea level.
