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.

Introduction 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. [1]. So, in hope of all-out solution of these water issues, a unique step should be added in the SDGs. Besides, due to its interconnection with other global issues, a worldwide goal concerning water issues is being a must to put in effect some effective vows and coordinated actions to every water issue to achieve global development goals. Water issues are getting much worse and alarming nowadays. [1]. Interconnections among global issues like water, social and economic issues are getting more alarming with the help of rapid population growth, change of land usages, rapid unplanned urbanizations, and aftermath of climatic degradation and pollution of water simultaneously. Reasonably, water security has aroused the necessity of the intersection of hydrology, ecology and society as well. [1]. Huge bulk of waste water from domestic and industrial areas carried by their surrounding water bodies like rivers and lakes is getting discharged into the seas which is frequently polluting waters as a whole. These contamination causes the most of all heavy metal contaminations. [2] Consequently, heavy metals get into fish body from those contaminated waters and alter the organisms. These contaminants not only damage the organisms but also get deposited into aquatic affecting bioconcentration, bioaccumulation and food chain system. Consequently, these contaminants can threaten the health of mankind. [2] Fishes maintain their normal metabolism by taking metal from water, foods and sediments. But a high concentration of heavy metals caused by water pollution is causing toxic effects in fish world. [2] Now a day, appraisal of water quality is based only on chemical measurements and analyses of the water itself through early detection of changes in the quality of water resources impacted by anthropogenic contaminants along with microbial infestation. But a need has always been existed for a rapid means of assessing the "health” for sustainable management of water bodies in Bangladesh. A reliable, field applicable method with a valuable tool which determines stress levels in fish could provide resource managers to determine the severity of health of water for immediate management. This is possible with the use of biotests or biomarkers, e.g. investigations of the induction of heat shock proteins (proteotoxicity evaluate). [3] Heat shock protein (HSP) genes are highly conserved as well as are constitutively expressed in all tissues in response to stress. Stress disrupts homeostasis, the regular conformation of proteins demanding the aid of HSP to regularize the effect. In fish, stress could be due to any minor change in the environment [4]. Fish are exposed to many kinds of stressors such as microbial infection, toxic
