Salinity effects

Blue crab

Scientific name
Callinectes sapidus
Reference

FINS (2006)

Study location
Texas
United States
Salinity tolerance results

It was observed that blue crabs were most abundant in salinities of between 18-23 ppt, although they were spotted in all regions of the salinity spectrum of a Texas estuary and are therefore presumed euryhaline.

Salinity tolerance results

S. tiburo juveniles thrive in moderately saline conditions (30-35 psu); C. isodon thrive in (<20 psu) lower saline conditions, S. lewini prefer highly saline conditions (>35 psu). Sharks utilized in the study were juveniles.
