Abstract

Male Catfish Rita rita has higher Haemoglobin Concentration than Female Fish

Highlights

  • Le Hematological analysis of blood of Rita rita, showed significant differences between total erythrocytes count, hemoglobin concentration and erythrocyte sedimentation rate of the two sexes

  • A ish live in very intimate contact with their environment F t and are very susceptible to minor physical and irs chemical change in the surrounding. These changes can alter their physiology which may be assessed by blood parameters

  • Hemoglobin was enumerated as recommended through Sahli hemogloblenometer (Hesser, 1960) and hematological variation in catfish Rita rita from Pakistan. expressed in g% in broad day light from lower to the top of Earlier various workers have published hematological the measuring tube through graduation mark of miniscus

ABSTRACT le Hematological analysis of blood of Rita rita, showed significant differences between total erythrocytes count, hemoglobin concentration and erythrocyte sedimentation rate of the two sexes. Male fish had total erythrocytes 5.05 ± 0.5 × 106 and hemoglobin content 11.5 ± 1.5 g/in ml compared to 4.04 ± 0.5 × 106 rtic and 7.3 ± 1.3 g/in ml in the female. Key words Hematology, Hemoglobin concentration, Erythrocyte sedimentation rate, Rita rita, Indus River. A ish live in very intimate contact with their environment F t and are very susceptible to minor physical and irs chemical change in the surrounding. These changes can alter their physiology which may be assessed by blood parameters. No published information is available on the in different seasons especially during breeding season
