Abstract

PEPITO, GLADYS G., University of the Philippines at Los Banos, April, 1987. A Comparative Electrophoretic Study of Two Different Races of Common carp, Cyprinus carpio Linnaeus var. communis Raised in the Same Environment.

Major Adviser: Mr. Ivan Marcelo A. Duka

Isohemoglobin patterns of two races of common carp, Cyprinus carpio Linnaeus var communis were studied to compare possible differences. Thirty individuals each for the Philippine common carp and Japanese were obtained from the same environment with relatively the same condition: pH range: 7.2 - 8.1; temperature: 25`C - 30'C, with an average dissolved oxygen content of 3.72 mg02 /L. Analyses were done through polyacrylamide disc gel electrophoresis. Both sets of samples showed complex and heterogenous hemoglobin patterns. A total of 23 isohemoglobin bands ranging from eight to thirteen bands were observed for the Philippine common carp. In contrast, a total of 14 isohemoglobin bands ranging from four to nine bands were observed for the Japanese carp. Cathodal and anodal isohemoglobins were predominantly expressed in both races. Statistical analysis for the equality of variance of the relative mobility of isohemoglobins showed that there is a significant difference in the variability of isohemoglobins between the two races. The difference, the complexity and heterogeneity of the band patterns of both races were attributed not only to their environment but also to the particular type of race the individuals belong.
