The total blood volume, relative (%) blood volume and haematocrit value of Mystus bleekeri of six different weight groups ranging from 24 to 76 grams were studied in winter and summer months at water temperatures of 18°C and 28°C. The total blood volume at both temperatures increased from lower to higher weight groups. The correlation coefficient between total blood volume and body weight were 0.8587 at 18°C and 0.9946 at 28°C. Total blood volume in all weight groups was greater at the higher temperatures and most results were statistically significant. The relative blood volume and haematocrit decreased from lower to higher groups at both temperatures.

Key words : Blood volume, Mystus bleekeri, Summer, Winter months.
