Abstract: Electrophoretic techniques were used to analyze the genetic variation of Sebastes paucispinis and S. goodei. Three types of variation were examined: variation between the muscle and liver tissues of an individual, between individuals of a species, and between species. Six enzymes systems were used: phospholgucomutase (PGM), glucosephosphate isomerase (GPI), esterase (EST), isocitrate dehydrogenase (IDH), sorbital dehydrogenase (SDH), and malate dehydrogenase (MDH). GPI, IDH, and MDH showed variation between tissues within individual fish. Allelic variation was detected at GPI-B in S. paucispinis. MDH proved to be the only distinguishing enzyme between the two species; all other isozymes had identical electrophoretic mobilities in both species.
