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.

Atlantic croaker

Scientific name
Micropogonias undulatus

Salinity tolerance results

Juvenile and adults both appear to prefer salinities of <15 ppt.

Atlantic rangia

Scientific name
Rangia cuneata
Reference

BIO-WEST (2009a)

Study location
Louisiana

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.
