ABSTRACT
The present work reports re,sults of examination of the blood of two
e’ryhaIme sp,ecies. Anguilla vulgaris and MugU cephabus, presellllting the normal levels of the ery’throcyooilf’.)unts, s,ize of the ery11hl”ocytes and the
erythI1oclytle, nuclei, the n~ber of leucocytes alud their tJr::fferel11tial ciounts,
h.aematocrit values, haem.’oglohin content, erythrocyte sedimentation rwte and
specif’ic gravity. It is to be noticed that., the cycl:ilc nature of haematocrif
variaMlity is very lsiimilar to that observed in hi.l haenlatological parameters, the red cell count,
the haematorcrit value lan/d the haemoglobin content.
Seasonal variations are also demonsilra:l:ed 1n the total differential oounts
of leuoocytes. An eocplana,tion for these chaillges is not yet available, since
the exact functiJoln of each leucOiCyte type iJn. tdeoslt,s is still ohscure.
