Measurement of blood volume in the Indian mud eel Amphipnous cuchia (Ham.) (amphipnoidae; pisces).

The blood volume of 10 male and 8 female Amphipnous cuchia (Ham.) were measured through dilution technique method using Evans blue and sodium citrate as anticoagulant. This method was established against heparin. The mean total blood volume and the blood volume per 100 g of body weight for all the weight groups in male were 9.73 +/- 2.45 and 3.10 +/- 0.66, and in female were 10.34 +/- 2.78 and 3.13 +/- 0.66 respectively. The total blood volume of male and female fishes increase as an exponential function of its total body weight.
