Abstract
Two species of Anabas Cuvier, 1816 (Osteichthyes: Anabantidae): A. testudineus (Bloch, 1795) and A. oligolepis Bleeker, 1855 are widely distributed in India. Since both species are represented in one habitat — Lake Kolleru, and are very closely related, they were compared using starch gel electrophoresis. Electrophoretic separation of proteins of eye lens, skeletal muscle and heart muscle revealed differences such as i) absence of one protein fraction in one of them, ii) mobility and iii) staining intensity of some of the bands. The esterase (non-specific) patterns of serum, liver, kidney, skeletal muscle, heart muscle and eggs also showed differences. The LDH fraction of eye lens showed a difference in mobility.
