Simultaneous determinations of microhaematocrit, erythrocyte numbers and haemoglobin concentrations have been obtained for samples of carp and trout of both sexes acclimated to various temperature regimes, and varying seasonal and nutritional states. Because haematological parameters have been used as indices of physiological condition in fishes correlational and multivariant regression analyses were carried out in an effort to determine whether valid correlations existed between the readily‐determined parameter, microhaematocrit, and the other 2 variables. Results obtained indicate that microhaematocrit can be used as a general index of haematological status in the carp but not the brook trout.
