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.

Keywords:

cyprinids, hypothermic stress, hematological indices, celular respiration.
