TPWD (1998) *
Preferred salinity was shown to be between 10-20 ppt.
Normant & Lamprecht (2006)
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.
Engle et al. (1994)
An increase in salinity (up to 40 ppt) typically yields an increase in the mean number of benthic species and polychaete species.
Saraswat et al. (2015)
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.
MBHE (2008)
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.
