Biometric study of mercury exposure on the early larval stages of brine shrimp, Artemia spp. (Crustacea: Anostraca) Dola Bhattacharjee*1 and Alireza Asem2, Amin Eimanifar3 1) Centre of Advanced Study in Marine Biology, Annamalai University, Parangipettai, India 2) Protectors of Urmia Lake National Park Society (NGO), Urmia, Iran 3) Iranian Artemia Reference Center, Urmia, Iran   Summary: Artemia is being used as a rewarding tool in toxicology. Usually; the brine shrimp larvae are tested to determine the effect of heavy metals on biological systems. The present study assessed the secondary effect of mercury at various concentrations on the biometry of nauplii and meta-nauplii of Artemia sp. Generally, the total length and abdominal width were limited by increasing the mercury concentrations (Fig 1. and Fig 2.). However, hormetic responses were also observed under certain concentrations.
