Tujuan dari studi ini adalah untuk menganalisis mortalitas dan kerusakan jaringan insang udang vaname yang didedah logam kadmium pada salinitas yang berbeda. Hasil peneltian menunjukkan toleransi udang vanamae terhadap logam kadmium menurun sejalan dengan penurunan tingkat salinitas. Tingkat toleransi yang rendah dan kerusakan jaringan terberat terjadi pada udang yang didedah pada salinitas 10 ppt (LC 50 - 96 jam : 1,66 ppt Cd) diikuti berturut-turut salinitas 20 ppt (LC 50 - 96 jam : 2,54 ppt Cd), 30 ppt (LC 50 - 96 jam : 4,41 ppt Cd) dan 40 ppt (LC 50 - 96 jam : 5,16 ppt Cd).

A static test was applied as an acute toxicity test technique. The objective of this study was to assesst the mortality rate and the damage of gill tissue of L. vannamei exposed to cadmium at different salinity. Tolerance to these metal was decreased progressively according to the salinity level. The less tolerant salinity and the heaviest damage gill tissue was found at lowest salinity/10 ppt (96 h LC 50 : 1.66 ppt Cd) and followed by 20 ppt (96 h LC 50 : 2.54 ppt), 30ppt (96 h LC 50 : 4.41 ppt), and 40 ppt (96 h LC 50 : 5.16 ppt), respectively.
