Twelve species as L. argentimaculatus, L. fulviflamma, L. fulvus, L. johnii, L. lemniscatus, L. lutjanus, L.madras, L. quinquelineatus, L. rivulatus, L. russelli, Pinjalo pinjalo and Pristipomoides typus were collected from the Visakhapatnam fishing harbour, India. The present study is an attempt to evaluate the genetic diversity in the species of snappers by using Sodium Dodecyl Sulfate Polyacrylamide (SDS-PAGE) gel electrophoresis. Proteins were extracted from muscle tissue. The molecular weights of protein bands were observed and its range was from 5 to 226 KDA. Relative mobility values range from 0.014 to 0.959 in twelve species. UPGMA dendrogram formed revealed two major clusters.
