Gorakhpur is an agricultural zone with a tropical climate. It boasts of a large freshwater lake. The lake is a major source of fish and shellfish for this region. It is, however, heavily polluted. It receives the sewage refuse of the major part of Gorakhpur city through an approximately 6 km long and mostly open sewer, as well as the agricultural run-off from the large number of agricultural fields surrounding the lake on all sides. Toxicity of lake water from organic enrichment through sewage and contamination by agrochemicals has reduced the fishery catch of the lake to less than half during the past years. An evaluation of the toxicity of these pollutants is, hence, essential. It has already been established that these contaminants produce hematohistological, leucocytic and hemostatic anomalies, and affect the blood chemistry, in the freshwater catfish, Heteropneustes fossilis, which is a very common food-fish of this region. The deleterious effects on the number, volume, size, hemoglobin content and sedimentation rate of the erythrocytes of the catfish are described here.
