Genetic variability in Hoplias malabaricus (Osteichthyes: Erythrinidae) in fluvial and lacustrine environments in the Upper Paraná river floodplain (Paraná State, Brazil).

Abstract excerpt

Genetic variability in Hoplias malabaricus, from two localities in the upper Paraná Riverfloodplain, was investigated by starch and polyacrylamide gel electrophoresis. A total of 52 specimens were analyzed for 14 enzymatic systems. Twenty-three gene loci of 13 enzymatic systems (AAT, ACP, ADH, GDH, G6PDH, GPI, IDH, LDH, MDH, MEP, PGM, PER, and SOD) were analyzed by starch gel electrophoresis (Penetrose-30). The...
