Comparative electrophoretic studies of muscle, eye lens and heart protein in fishes from the Arabian Gulf

Muscle myogen, eye lens and heart protein have been studied in 31 species of fishes from Kuwait, Arabian Gulf. The electrophoretic analysis revealed that muscle myogen can be considered a good taxonomic criterion to differentiate the families Ariidae, Belonidae and Lutjanidae from the other fish families studied. Within the Lutjanidae and Pomadasyidae the muscle myogens can be used to differentiate Lutjanus kasmira and Pomadasys argenteus, respectively. The muscle myogens can also be used to differentiate Sardinella perforata, Platycephalus inducus, Drepane longemana and Psethodes erumei. Eye lens protein can be considered a good taxonomic criterion to differentiate between the fish species studied and especially among the families Belonidae, Lutjanidae, Pomadsyidae, Sparidae and Scaenidae. Within the Lutjanidae and Sparidae, the eye lens protein can be used to differentiate Lutjanus kasmira and Acanthopagrus berda, respectively. Heart protein is not considered a good taxonomic criterion to differentiate the species of fishes studied, but can distinguish Lutjanus coccineus from the remaining species studied.
