dc.description.abstract A laboratory experiment was undertaken to analyze the effects of salinity on growth, body composition, oxygen consumption, and ammonia excretion of anadromous American shad (Alosa sapidissima) juveniles. Results showed the best survival rate occurred at 5‰ and 15‰. The relative weight gain and the specific growth rate declined as salinity increased. However, feed conversion rate increased with increasing salinity. Oxygen consumption rates showed a parabolic relationship in relation to salinity. From the quadratic relationship (y= -0.0004x2+0.0166x+0.319; R2=0.801; P<0.05), the highest oxygen consumption rate occurred at a salinity of 20.75‰. The ammonia excretion ratio decreased significantly as salinity increased from 10‰ to 15‰. No further differences were observed in salinities ranging from 15‰ to 40‰. There were no significant influences of salinity on whole body protein and moisture content. Lipid content declined as salinity increased. Results indicate that an appropriate increase in salinity was beneficial to the culture of American shad juveniles. The optimal salinity for American shad juveniles ranged from 15‰ to 20‰.
