allozyme variation in a threatened freshwater fish, spotted murrel (channa punctatus) in a south indian river system.samples of the spotted murrel (channa punctatus) were collected from three rivers of tamil nadu and kerala. the allozyme variation of c. punctatus was investigated by polyacrylamide gel electrophoresis. eighteen enzymes were detected, but only 10 (est, pgm, g3pdh, g6pdh, sod, gpi, odh, gdh, xdh, and ck) showed consistent phenotypic variations. allele frequencies were estimated at the 18 polymorphic loci representing 10 enzymes. two rare alleles, est-4*c and g6pdh-2*c, were noted in the tamirabar ...200717265185
