Effect of Sub-Lethal Concentration of Dipterex on the Blood Parameters of Fish Trichogaster fasciatus
The fishes serve as indicator of water quality and are meant for ornamental and food value. Use of pesticides dose on their lives and almost all the pesticides go to water bodies in any from and any way. Environmental pollution is a burning issue at the moment for whole world. Many factors are behind these various types of pollution and varied effects are revealed by the pollutants. Sub lethal concentration of Diptrex on certain blood parameters such as Total erythrocyte count (TEC), Total leucocyte count (TLC), Haemoglobin concentration (Hb conc.), Erythrocyte sedimentation rate (ESR) and packed cell volume (PCV) have been studied. Dipterex is an organophoshorus insecticide and its LC has been calculated by the log- 50 dose/probit regression line method. Sub lethal concentration of Dipterex given to fishes showed that TEC, Hb concentration and PCV decreased significantly, while TLC and ESR have been increased after 1, 7, 15 and 30 days treatment respectively.
