4. Summary
The erythrocyte counts, hæmoglobin content, coagulation period and cell and nuclei size of the blood of Hilsa from the river Hooghly have been determined. Using the Climbing Perch as test material, it has been shown that the characteristics of the blood taken from the heart of live fish are not significantly different from those of dead fish which have been preserved in ice immediately after capture.
The mean erythrocyte count of Hilsa is much higher than that of many other species of fish and this appears to be correlated with the relatively small size of the cells. The coefficients of variation of the different characters are below 20%, which may be considered as the normal variation in the Hilsa of the Hooghly for purposes of comparison with blood samples of other stocks of Hilsa.
