Abstract

Comparative analysis through polyacrylamide gel electrophoresis was done on blood samples from thirty tilapia from Sampaloc Lake in San Pablo City and another thirty from Laguna de Bay in School, Calamba. Results indicate that both sample populations exhibited multiplicity of isohemoglobins. A total of 19 different bands were observed from Sampaloc Lake samples, with each sample exhibiting 8 - 12 bands. they were observed to be less cathodal, with band intensities from barely detectable to moderately intense with very few highly intense bands. According to their relative mobilities and intensities, the isohemoglobin bands were grouped into four general sets. For samples obtained from Laguna de Bay in Sucol, Calamba, a total of 23 different bands has been observed, each sample exhibiting 8 - 15 bands. Generally less anodal, this population sample had band intensities ranging from barely detectable to highly intense. Using the same criteria, the isohemoglobin bands of this population sample were likewise grouped into five sets.
