Lactate dehydrogenase (LDH) in 27 species of amazon fish: Adaptive and evolutive aspects
1. 1. Among the 27 species of Amazon fish belonging to the orders Rajiformes, Clupeiformes, Osteoglossiformes, Characiformes, Siluriformes and Perciformes here analyzed, 56% showed an electrophoretic pattern of five, 7% of four, 30% of three, and 7% of two LDH isozymes, suggesting the presence of bo...
