Abstract

Problems of water quality with particular refer to Natural and Synthetic Chemicals have greatly intensified during recent past. The most dangerous fact of these chemicals is that, they do not decay and/or for break down readily in natural environment. Once incorporated in a food web, they pass along and accumulate in the highest member of web. Fish being at high trophic level, also gets affected through food chain. Among aquatic pollutants, dyes, pigments and effluents from textile industry are of utmost importance, which affect the life processes of aquatic organisms. The present study is undertaken to assess the toxic effects of chronic exposure to textile dyes, on protein and glucose level in female gonads of fresh water teleost Heteropneustes fossilis. A decline in ovarian protein and glucose indicates adverse effects of textile dyes on the reproductive physiology of fish.
