Salinity and temperature tolerance of juvenile Mesopodopsis orientalis: laboratory studies

Seasonality, reproductive biology and ecology of Mesopodopsis zeylanica (Crustacea: Mysida) from a tropical estuary (Cochin backwater) in India

“…The salinity tolerance range of M. zeylanica in the backwaters (0 to 32.5) is more or less similar to the laboratory values found in M. orientalis (1.8-35.0) (Bhattacharya 1982). In general, species of Mesopodopsis have a wide range of salinity tolerance, from almost fresh water to absolute seawater (Bhattacharya 1982, Greenwood et al 1989.…”

“…Belyaev (1949), Remane &Schlieper (1958), andMcLusky &Heard (1971) pointed out that euryhaline species are well adapted to live in an environment with wide fluctuations in salinity, though their capability to prevent excessive changes in their internal environment by maintaining their blood hyper or hypo-osmotic to the medium. A series of experiments were carried out by Bhattacharya & Kewalremani (1972) and Bhattacharya (1982) to determine the reaction of adults and juveniles of its closer congener, M. orientalis to varying salinities, 1.8-35.0 at different temperatures. The salinity tolerance range of M. zeylanica in the backwaters (0 to 32.5) is more or less similar to the laboratory values found in M. orientalis (1.8-35.0) (Bhattacharya 1982).…”

Seasonality and biological characteristics of the shallow-water mysid Mesopodopsis orientalis (Crustacea: Mysida) on a tropical sandy beach, Malaysia

“…The population dynamics of M. orientalis in Indian coastal waters has been reported to correlate with the monsoon (Nair 1939, George 1958, Bhattacharya & Kewalramani 1972, although Sarkar & Choudhury (1986) showed only a weak correlation with the monsoon in the Hooghley estuary. Bhattacharya & Kewalramani (1972) and Bhattacharya (1982) studied temperature and salinity tolerance in the laboratory and demonstrated that M. orientalis of Indian coastal waters could survive under an extremely wide range of temperature and salinity conditions even though it tends towards a low salinity preference, particularly in the early life stages.…”

Seasonal availability and population structure of Eurobowmaniella simulans W. Tattersall, 1915 (Crustacea: Mysida) along Vizhinjam coast, Kerala, India

“…E. simulans was found to be a euryhaline organism, and comparatively higher abundance of mysids (edge effect) were recorded in certain sites where small streams conjoins with the sea. The effect of salinity on mysid availability and distribution were well documented for some species by Baldo et al (2001), Bhattacharya (1982), Bhattacharya and Kewalremani (1972), Biju and Panampunnayil (2010) in their studies. Bhattacharya (1982) opined that the mysid, Mesopodopsis orientalis can tolerate from near freshwater condition to 60 ppt.…”
