Abstract: Fish proteins occupy an important place in human nutrition. They are well balanced with essential amino acids and are comparable to other proteins of animal origin. Moreover, carbohydrate content of the fish flesh is very low. Considering their nutritional value, it is essential for any nation, which is desirous of developing this rich protein source to develop a healthy freshwater fishery or an efficient agriculture system, for which maintenance of the environmental water quality is a prerequisite. Herbicides are synthetic chemicals used for weed control. A major source of herbicides in water bodies is the runoff from agricultural fields. Some herbicides also enter inland waters, from industries, which up in their manufacturing processes or from the manufacturing of herbicides themselves. Herbicides adversely affect a wide range of organisms including beneficial insects and fish. Herbicides accumulate in the tissue of aquatic organisms through bioconcentration and biological magnification and adversely affect their metabolic processes including reproduction. The aquatic organisms are sensitive to environmental changes. Herbicidal pollution causes the most dangerous health hazards apart from creating adverse effects on fish production. Review of literature revealed that most of the studies are related to individual effect organophosphorus or chlorotriazine herbicidal compounds on fishes. However, the relative effects of herbicides on Indian major carp, Labeo rohita have not been yet known. Hence, the present investigation has been carried out to study the effect of herbicides atrazine and glyphosate on physiological, biochemical and ultrastructural aspects of the fingerling Indian major carp, Labeo rohita (Hamilton).
