Abstract
Early growth of chum salmon was investigated in terms of rearing pond condition. The number of fingerling showed big differences by rearing pond $1,003,000{\sim}1,865,000$. The fork length of fingerlings ranged from $3.20{\sim}3.78cm$ and body weight ranged $0.34{\sim}0.49g$. Daily temperature of rearing water in January to March was $6{\sim}8^{\circ}C$, which is inadequate for salmon growth. pH was $6.0{\sim}6.3$ in early and mid February, 6.5 in late February and $6.5{\sim}7.0$ in March. Dissolved oxygen concentration was lowest from 8 a.m. to 6 p.m. and increased after 6 p.m. The maximum value was seen from 9 p.m. to 6 a.m. The mortality of fingerlings was 5 times higher in the daytime than at night because of dissolved oxygen. Growth of fingerlings was affected by daily ration, concentration of dissolved oxygen and rearing temperature.
