Abstract
The study provides information on the
correlations established between cellular
respiration and the hematological parameters,
under the influence of prolonged starvation and
hypothermy, during wintering, in three one
summer-old culture cyprinids: common carp
(Cyprinus carpio), silver carp
(Hypophthalmichthys molitrix) and bighead carp
(Aristichthys nobilis).
The intensity of cellular respiration in both
gills and muscle, as well as the hematological
parameters (hemoglobin, hematocryte and the
number of erythrocytes), were determined prior to
and after fish wintering.
The observation to be made is that, under
the influence of prolonged starvation and low
winter temperatures, the consumption of cellular
oxygen occurs (more pronounced in common
carp - especially in muscles), correlated with
higher values of the sanguine parameters (more
intense in common carp and lower in bighead
carp), mainly for Hb, Ht and erythrocyte number,
which may be interpreted as an adaptive
compensating response.
