Salinity effects

American oyster

Scientific name
Crassostrea virginica
Reference

Cake (1983)

Study location
Louisiana
United States
Salinity tolerance results

American oysters have a normal salinity range of 10 to 30 ppt. Spawning American oysters can be found in areas of 10 to 30 ppt. Larvae are prevalent in regions from 7.5 to 22.5 ppt. Survival of Crassostrea virginica at <5 ppt is highly unlikely.

Salinity tolerance results

Larval rangia have a salinity tolerance of between 2-10 ppt, and require salinity for development. Adults will not tolerate salinities >18 ppt.
