Abstract:

Four fishing were operated at Shuishangmingyue,Zhenbaofang,Meihu and Ludingshan to capture silver carp and bighead carp in September 2009. The weight of silver carp was from 6000g to11000g and the age was from 3 to 5. The weight of bighead carp was from 7000g to12000g and the age was from 3 to 5. The growth equation of silver carp was and . The growth equation of bighead carp was and . The rapidest growth period was from age 3 to age 5. This study was mainly about the growth characteristics and community structure which will provide evidence for protection and utilization of fishery resources in Lihu lake.
