Abstract：The growth characteristics of juvenile wolf eel Anarrhichthys ocellatu were observed and researched under the sea water temperature of 10.0—16.0 ℃. Related growth data were measured and analyzed. The results showed that the average initial body weight and average body length of the newly hatchings were increased from (0.05±0.01) g and (4.30±0.01) cm to (500.35±44.47) g and (72.65±6.32) cm after 11 months of growth. There was quadratic function between body weight (m) and age (t)(month):m=5.7228t2-21.545t+13.863,r2=0.9868,with the average daily weight gain of 1.52 g and instantaneous weight growing rate of 2.79. There was linear relationship between the total length (L) and age:L=6.3452t-1.4895,r2=0.9824,with average daily total length gain of 0.21 cm, and instantaneous total length growing rate of 0.86. The regression curve between body weight and length was m=0.0033L2.8258,r2=0.9705, with the power of 2.8258, less than 3, indicating that the growth rate of body weight and length was not consistent, with a negative allometric growth stage. The body length had an inflection point at the age of 7.6 months,and the weight did not appear. The coefficient variation of body weight and length was changed from 1.79 to 11.80 and 0.15 to 8.95,the fish population showed a change in the growth dispersion intensification-weakening. Condition factor was changed from 0.06 to 0.30 in different months,and the change in condition factor was firstly increased and then decreased. The 11 month old fish had average body weight of 500 g under the sea water temperature of 10.0—16.0 ℃, and the wolf eel grow rapidly at low temperature, can farm at high density with promising development prospects.
