Electrophoresis used for Identification of Fish Species

In the past, the identification of fish species was carried out mainly by examining the external morphological characteristics. In the present day, electrophoresis of sarcoplasmic proteins, serum proteins, liver proteins and a number of enzymes often have been used by some researchers as an aid in the species identification of fish. Recent studies indicated that serum proteins can present taxonomic values, when the serum proteins of different fish species are examined electrophoretically.
