Abstract

The natural population ofArtemia appeared inthe lastweekofOctoberfollowinga drop inthe average temperature (26°-33°C)
by largescale hatching of cysts. It established rapidly byovo-viviparous modeof reproduction and acquired peak density of 13
individuals per literinNovember-December (20°-26°C)and disappeared during May-June(day temperature, 37°C and above).
The optimal temperature regimefor sustenance and growth of population was23°-28°C. A widerange of salinity tolerance was
observed butthe temperatureappeared to playa rolemoreimportantthan salinity incontrolling growth, survival, and reproduc-
tion of Arternia in the saltworks of KorangiCreek.
