We studied on the relation between the amount of extracted blood and the decreasing hematocrit value in specimen of eel (40~65g)and carp(420~650g) (66 and 12 specimen), by the continuous several extractions of 0.5ml each time from the same fish. The decreasing hematocrit values were from 1.3%to 2.5%in eel and from 1.1%to 2.5% in carp in each extraction. The decrease of hematocrit value of all specimen was caused when the total amount of extracted blood came to 1.9, 1.6 and 1.1% (ml/g)in the eel of each body weight (40~65g, 70~95g, 100g<), 0.8% (ml/g) of body weight in the carp. Namely, the reaction of the increase of the evythrocyte counts is presumed to bo unable to occur in such short intervals (2~27 minutes) of the blood-extraction.
