Nazmul Haque 2 Assistant Professor, Institute of Education and Research, University of Dhaka, Bangladesh Department of Fisheries Biology and Genetics, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh Water is working in a very significant role in all the sectors of sustainable development and therefore being responsible for numerous global and economic crises. Need exists for rapid means of assessing the "health' of water bodies in Bangladesh. This study aims to assess health indicator for aquatic lives. Nile tilapia (Oreochromis niloticus) were studied in the laboratory tanks of constant temperature, 28°C and were treated with K2Cr2O7 and Psedumonas, commonly found stressor in the water bodies of Bangladesh. Test animal was used to obtain tissue for conducting SDS-PAGE. SDS-PAGE was applied to protein samples to linearize proteins. A dominant band of 100 kDa was found in the brain, gill and intestine after c exposure. Presence of 100 kDa suggests that HSp 100 can be the ideal stress marker. The present study also indicates that the use of stress protein for biomarker is easy to use and sensitive for managing water quality to achieve SDG in Bangladesh. http://pubs.sciepub.com/ajwr/6/5/3/ajwr-6-5-3.pdf HSP100 stress protein biomonitoring environmental stressor water management
