Length and Weight (LW) Related Variations on Haematological Parameters of Hetropneustes Fossilis (Bloch.)
Abstract The paper mainly described the haematological values of a fresh water catfish Hetropneustes fossilis (Bloch.) in relation to its length and weight which are the prime basic factor of the differences in blood parameters of any living creature including fishes. The hematological parameters showed significant differences with increase in length and weight of the fishes. Differential leucocytes count did not showed any significant differences except macrophages and differential erythrocytes count showed significant differences only in macrocytes. All three groups (Length and weight) of fishes showed significant positive correlations for total erythrocytes count, hemoglobin, mean corpuscular hemoglobin and erythrocyte sedimentation rate while negative correlation was noted for mean corpuscular hemoglobin; mean cell volume. Among differential leukocytes count only neutrophil showed positive correlation, while other parameters did not show any significant correlation. In differential erythrocyte count only microcytes showed significant positive correlation.
