Inter-specific and intraspecific eye lens protein differences in some sciaenid fishes from Goa coast

Abstract

Soluble eye lens nuclei proteins of sciaenid fishes were studied by cellogel electrophoresis. Four distinct patterns characterized by the number of bands, mobility and staining intensity were observed. Morphological studies of these fishes showed that they belonged to species Otolithus ruber (Schneider), Johinius sina (Cuvier) and J. argenteus (Houttuyn). The eye lens proteins of J. argenteus showed 2 types of electrophoretic patterns suggesting the occurrence of 2 breeding populations of J. argenteus
