Present surveysynthesized informationon fish biodiversityin the perennial freshwater body of Ramnagar, East Midnapore district of West Bengal, India. Wedocumented 45 fish species under 29 genera. 18families and 8 ordersduring the periodsfrom 1990to 1995,whereas,34 speciesfrom 21 genera and 12 families under 7 orders were recorded presently from freshwater bodyof different perennial pond. This present database ofichthyofuuna clearly indicated that II fish species, 8 genera, 6 families and 1 order have lost from this investigated area. Basically, this agricultural based area associated with profuse application of various chemicals, poisons and drugs in agricultural field that largelypolluteperennialwater bodyand ultimatelyexertinggrowingpressureon livingaquaticresources and driven significant fish biodiversitydecline. However, over fishing, chemicals, agricultural runoff and other formsof pollution are most important factorswhich should be restricted for the conservation offreshwater fish biodiversity. Therefore, it may beconcluded that preparation ofzone wise database ofthcse information and their implementation through Government and various Non-Government Organizations would be the key tools for conservation of freshwater fish biodiversity.
