1 - In the present work, some morphological and haematological studies were carried out on the mirror carp, Cyprinus carpi0 . V. spec-ularis Lac. The fish samples were collected from Barrage Experimental Fish Farm, near Cairo.2 - The fish samples used in morphological inv-estigations were at the first year of life and ranged in total length from 2 - 31 cm .3 - The total length/standard length index (T.L/ S.L. ) ranged from 1.20 to 1.32 with a mean of 1.26. The value of this index tends to decrease with increase of total length.4 - The standard length/head length index (S.L./ H.L. ) varied from 2.62 to 3.35 with a meanof 3.04. The value of this index shows a trend towards increase with increase in sta-ndard length.5 - The standard length/body depth index (S.L./B.D. ) ranged from 2.09 to 2.80 with a mean of 2.45. This index showed higher values in smaller fish samples relative to that of lar-ger ones.6 - The regression equation for the standard length was found to be :Standard length = - 0.4345 + 0.8288 total length.7 - The regression equation for the body depth was found to be :Body depth =-0.2112 + 0.3450 total length .8 - The regression equation for the head length was found to be :Head length = 0.7675 + 0.2190 total length.9 - The observed and calculated values for themorphometric measurements showed close fitness.10-The regression equations for morphometric measurements in relation to the total length indicate that isometric growth occurs.11-The length-weight relationship :W = cLn was found to beW = 0.01276 L105762The weight increases at a rate equal to the cube of length.12 - Close agreement is shown between emperical and calculated weights.13 - The condition factor ”K” ranged between 1.1481 to 1.6348 with an average of 1.4906. The larger fish samples showed higher valuesof ” K ”14 - The mode of lengths from 5 cm. to 30 cm. lied at 21 cm.15 - The mirror carp showed average total length of 178 mm. and average weight of 135 gm. at the first year of life.16 - The mean values of the erythrocyte countsranged from 1.035 million/cmm. to 1.2545 million/cmm. in fish samples ranging from 18 to 28 cm. in length.17 - Leucocyte counts ranged from 3.430 thousand /cmm. to 4.058 thousand/ cmm. in fish samples ranging from 18 - 28 cm. in length.18 - The number of erythrocyte and leucocyte increase gradually with the increase of len-gth and weight of the fish.19 - The mean value of erythrocyte sedimentation rate is 0.557 mm/h for fish samples ofaverage length 22.98 cm. and average weight 164.52 gm.20 - The average normal time of coagulation ofblood of mirror carp is 21.77 seconds for fish samples of average length 22.98 cm. and average weight 164.52 gm.21 - The average value of the specific gravity ofthe blood of mirror carp was found to be 1.0823. for fish samples of average length 22.98 cm.and average weight 164.52 gm.22- The average level of total protein in serumof mirror carp is 2.57 gm/100 ml for fish samples of average length 21.26 cm. and average weight 130.83 gm.
