Abstract

Effect of TRIPLOIDY induction on some hematological indices changes in all-female diploid and triploid RAINBOW TROUT, Oncorhynchus mykiss, at 20 months of age and prior to maturation was investigated in Shahid Bahonar Hatchery Center of Salmonids in Kelardasht-Iran in winter 2005 (mean temperature of 1.5oC). All female diploids were obtained by insemination of spermatozoa from sex reversed females (Neomale) with oocyte of normal females. All-female triploids were also produced similarly and by using heat shock of 26.5oC for 20 minutes to eggs 20 minutes post fertilization. Blood samples were taken from fish caudal vein using 5% EDTA as anticoagulant. Hematological data indicated that mean number of total erythrocytes, hematocrite value and hemoglobin content were significantly lower (p<0.01) and mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were significantly higher (p<0.05) in all female triploids. Furthermore, the results showed that mean number of total leukocytes was significantly lower in triploids than in diploids (p<0.01), but there was no significant difference in differential counts between Lymphocyte and Neutrophile percentage in diploids and triploids (p>0.05). Also, biometric results of 32 diploids and 28 triploids showed that mean weight of all-female diploids (348.90gr) was significantly (p<0.01) higher than that of all-female triploids (307.77gr), but there was no significant difference in total length fork length, standard length and body depth indices between these two groups (p>0.05). Final results revealed that although erythrocyte hematological indices were lower in triploids, but increased mean corpuscular volume and consequently higher mean hemoglobin concentration have set the equivalency between hematological indices in all-female triploids.
