The growth pattern of the selected third generation of Pacific oyster Crassostrea gigas with rapid growth at different stages was investigated by model fitting with regularly collected biological data. Results showed that at larval stage, the relationships between age (t) and shell height (SH), as well as age (t) and shell length (SL) both conformed to Logistic model, and the growth equations were SH=455.612/(1+9.500e?0.142t), R2=0.999;SL=462.476/(1+8.026e?0.108t), R2=0.996, respectively. At larval stage, shell height and shell length was linearly re-lated, and the linear regression equation was SL=0.76SH+18.82, R2=0.994. The growth pattern of C. gigas at grow-out stage showed significant seasonal variation. The polynomial regression equations between age (X) and shell height (SH), shell length (SL), shell width (SW), and total weight (TW) were SH=?0.0297X4+1.0365X3?12.0220X2+57.6500X?68.9260, R2=0.985;SL=?0.0173X4+0.5893X3?6.5702X2+30.2420X?34.4150, R2=0.986;SW=?0.0068X4+0.2620X3?3.2806X2+16.9170X?22.1410, R2=0.956; and TW=?0.0219X4+0.8234X3?10.1680X2+50.7040X?85.4110, R2=0.972, respectively. Shell height, shell length and shell width all showed significant power function correlativity with total weight. The regression equations were SH=23.645TW0.3213, R2=0.998; SL=12.337TW0.3776, R2=0.995;and SW=6.611TW0.3589, R2=0.981, respectively.
