Abstract

Blood samples were collected from thirty milkfish (Chanos chanos Forskal) of the same size and weight obtained from San Jose, Occidental Mindoro. Half of the milkfish came from a one-hectare freshwater lake in Bo. Bagong Sikat, San Jose Occidental Mindoro while the other half came from a 10.2-hectare brackishwater pond in Bo. Peg-asa Poblacion, San Jose, Occidental Mindoro. The blood samples were examined by means of disc gel electroploresis. The presence of multiple hemoglobin was verified in milkfish raised in both habitat. However, the electrophoretic hemoglobin patterns from brackishwater samples proved to be more uniform and homogeneous than those from freshwater samples. In brackishwater samples there were five bands which were distinct and consistent from sample to sample. On the other hand, the eletrophoretic patterns of freshwater fishes were more complex and heterogenous with three up to eleven bands. The aforementioned differences in hemoglobin bands were assumed to be adaptations of milkfish to the environment in which it is raised.
