Abstract
Muscle proteins usually provide useful information and therefore are frequently used as valuable diagnostic characters in the classification of fishes at species, generic, familial and higher taxonomic levels. The muscle myogen of four species of carangids. viz, Decapterus russelli, D. macrosoma, Selar crumenophthalmus and Megalaspis cordyla using horizontal slab polyacrylamide gel electrophoresis (Gel conc. 7.5%) is reported in the present communication. The number of protein fractions and the presumptive loci in muscle of D. russelli, D. macrosoma, S. crumenophthalmus and M. cordyla were found to be 9,7,6 and 5 respectively. The Rf value ranged from 21 to 84 for S. crumenophthalmus, 2 to 72 for M cordyla, 15 to 89 for D. macrosoma and 18 to 96 for D. russelli. The difference in number of fractions, their mobility pattern and staining intensity indicated species-specificity. With the limited number of samples used in the present work, there has been an indication of intraspecific polymorphism among three species of carangids, being 3.5% in D. russelli, 13.5% in D. macrosoma and 6.6% in S. crumenophthalmus. In M. cordyla no polymorphism was observed. This work also revealed that protein fractions in carangids can be used as species - specific markers, which could be helpful in resolving disputes in the event of any taxonomic ambiguity.
