Hatching rate and post‐hatch survival of Australian red claw crayfish Cherax quadricarinatus decreased with an increase in seawater salinity. An LC 50 of approximately 11 g/L was determined for juvenile survival in seawater through 15 d. Sodium chloride salinity levels as low as 1 g/L killed all crayfish within 15 d. Tolerance of young red claw to higher levels of seawater salinity than sodium chloride salinity may he due to the concentration of other ions in seawater.
