Abstract: Based on the fishery resources monitoring data collected in the East China Sea Region from 2001 to 2010, the present study analyzed the ecological parameters of Pampus argenteus using FISAT software and simulated the Von Bertalanffy growth equation, meanwhile, the inflection point age and the critical age have been discussed, finally, we put forward first capture fork length. The results indicate that the average fork length is 144.14 mm, with the group of dominant 110-170 mm, accounting for 72.83%. The relationship between fork length and body weight was expressed as: W=0.963×10^-5L^3.207. The growth parameters of Von Bertalanffy equation estimated by ELEFAN were L_∞ =267.75 mm, K=0.46, t₀=-0.32 a, respectively, and inflection point age and the critical age were 2.21 and 2.46 years respectively. Compared with the data obtained from Pampus argenteus in the East China Sea, value of L∞ has declined from 360 mm to the current 267.75 mm, inflection point age from 4.1 to 2.21, while growth coefficient K is increased from 0.205 to 0.46 since the 1980s, all these shows that the fish stock has been in serious status characterized with limit length reduction, growth speeding up, miniaturization and lower age. The current total death coefficient (Z), natural death coefficient (M) and fishing death coefficient (F) were 1.96, 0.57 and 1.39, the exploitation rate (E) was 0.71. Compared with the conditions of the years 1997-2000, all death coefficient showed a trend of increase significantly. High strength fishing was the main reason for the rise of total mortality rate and exploitation rate. In order to protect Pampus argenteus resources and make full use of fish growth potential, considered first sexual maturity and inflection point and critical age and fishery production status, the first capture fork length should be 164 mm now.
