Longley (1994) *
Adults prefer salinities of <20 ppt. Juveniles prefer salinities of between 6-21 ppt.
FINS (2006)
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.
TPWD (1998) *
Preferred salinity was shown to be between 0-15 ppt.
Randall et al. (2015)
P. occidentalis prefer highly saline environments (>35 psu). They are most abundant in areas with higher salinities.
Ward-Paige et al. (2015)
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.
