Salinity effects

Bay anchovy

Scientific name
Anchoa mitchilli
Reference

TPWD (1998) *

Study location
Texas
United States
Salinity tolerance results

Preferred salinity was shown to be between 10-20 ppt.

Benthic amphipod

Scientific name
Gammarus oceanicus
Reference

Normant & Lamprecht (2006)

Study location
Baltic Sea
Salinity tolerance results

Low salinity basin (5-7 psu). Physiological performance examined from 5-30 psu. Feeding & metabolic rates decreased with increasing salinity; nutritive absorption increased. Feces production and ammonia excretion rates decreased strongly from lowest to highest salinity. Greatest scope for growth at 7 psu.

Benthic communities in Gulf of Mexico estuaries

Salinity tolerance results

An increase in salinity (up to 40 ppt) typically yields an increase in the mean number of benthic species and polychaete species.

Benthic foraminifera

Scientific name
Rosalina globularis
Reference

Saraswat et al. (2015)

Study location
Goa
India
Salinity tolerance results

In a laboratory experiment, specimens kept between 10-15 psu were much smaller than specimens kept at >25 psu. Smaller specimens kept at 10-15 psu were unable to reproduce.

Benthic macroinfaunal communities

Reference

MBHE (2008)

Study location
Texas
United States
Salinity tolerance results

Benthic macroinfaunal communities were shown to thrive with a higher biomass in brackish (12-16 ppt), rather than marine (22-27 ppt), areas of the same bay due to freshwater inflow. Changes in community structure typically occur between 18 and 22 ppt.
