Paper Title
Oreochromis niloticus- a biomonitoring tool for assessment of trace metals of Theroor wetland, Kanniyakumari district, India
  Priyatharsini. P,  Dr. Sivasankari,  B. Dhanalakshmi

Currently wetland resources for being a significant source of fish production are receiving great attention all over India. One such environmental and economic important wetland in Kannyakumari district, the Theroor wetland which is now subjected to many of environmental changes due to influx of huge amount of discharges originated from different sources and as well as due to many human activities. This kind of action has transferred various toxic and risky elements into the food chain causing hygienically serious issues like contaminating the water of wetland and at higher concentration acting negatively on macro vertebrate- fish. Most of the metal ions which has the capability to bioaccumulate in aquatic organism at higher concentration may cause biochemical alternation finally leading to mortality. Due to the high sensitivity nature of the aquatic organisms towards the dissolved toxicants the fresh water fish Oreochromis niloticus collected from the three sectors (Eastern, Central, and Western) of the wetland has been utilized in the present study as biological indicator/ biomarker to evaluate the impact of metal toxicants at molecular level using proteomic tools. Thus, with the above context the present study was designed to evaluate some metal pollution in Theroor wetland using selected bioinformatic tools to give an overview of impact of metal through proteomic studies. The values of heavy metals (Ni, Hg and Zn) measured in the fresh water fish muscles of Oreochromis proven to be baseline data indicating the need for pollution monitoring in wetlands.

Keywords- Wetland, Heavy metals, Fresh water fish, Proteomics
