ABSTRACT
Three dominant species (?fMugilidae (Mugil cephalus, Liza ramada alld
Liza a1l1’Gta) were studied electrophoritically in two d?fferellt habitats (Marine
and Freshwatel). 171e similarity coefficiellts were studied for the differellt
~pecies in the marine and freshwater, alld for the d(fferellt sexes in each
species.
These studies revealed that the pattern ofserum proteins for most of the
studied species have been eleven/ractions. The variation was obvious between
protein patterns (?fjuveniles and adults (males andfemale~) of both Mugil
cephalus and Liza ramada.
The comparison (?f serum pl’Oteinogra111s between the adult ,\pecies
indicated that there was similarity between males or females (?f marine M
cephalus and Liza ramada. On the other hand Similarity was Pronounced
only between females ofL. ramada and those (?fL. aurata.
There were clear environmental effects 011 the patterns ofserum protein (?f
juveniles, males ofMugil cephalus and females (?f Liza ramada. But in the
case C?ffemales (?fMugil cephalus and males qfLiza ramada, this effect was
small.
