Biochemical polymorphism in yellow catfish, Mystus nemurus (C and V), from Thailand

Yellow catfish, Mystus nemums (Cuv. and Val.), is becoming one of the major freshwater species farmed by aquaculturists in Southeast Asia. It was of interest to examine levels of genetic subpopulation differentiation among samples of this species obtained from parts of its range, as well as to compa...
