Hematologic and enzymatic analysis of Ctenopharyngodon idella × Hypophthalmichthys nobilis F1 hybrids
Abstract
1. 1. Erythrocyte counts, hemoglobin concentrations and hematocrit values were determined for diploid and triploid Ctenopharyngodon idella × Hypophthalmichthys nobilis hybrids and the parental species. 2. 2. Comparisons of diploid and triploid hybrids with the parental species revealed low erythrocyte counts for triploids, high mean corpuscular hemoglobin values for triploids, elevated hematocrits for diploids and triploids and similar hemoglobin concentrations for all fish. 3. 3. Alkaline phosphatase, aldolase, and lactate dehydrogenase specific activities were determined spectrophotometrically. Levels of specific activity of these enzymes in the hybrids were consistently elevated above that of the parental species. These higher levels of enzyme activities in hybrids were probably the result of a breakdown in gene regulation. © 1983.
