Abstract

With regards to the importance of SCALE MORPHOLOGY in fish TAXONOMY, scale ultrastructure of two gobies including NEOGOBIUS melanostomus and N. fluviatilis from south Caspian Sea basin of Iran, was studied using SCANNING ELECTRON MICROSCOPY. Scales were gathered from below the dorsal fin and head. They were cleaned in potassium hydroxide solution and were prepared for the electron microscopy scanning. Variations are found in SCALE MORPHOLOGY of both fishes and in different body parts. Ctenoid scales are present on the head and body regions of both fishes. Focus in N. melanostomus is clear and located in the posterior part of scale and has round shape. Circuli are closed to each other and are regular throughout the scale. Radii in this fish are found only on the anterior part of scale and number of primary radii is more than the second and tertiary radii. But focus in N. fluviatilis is located in the center part of scale and is unclear; radii are found on the anterior and lateral regions of scale. Tongues or lobes of the anterior part are distinct in both fishes. Lepidonts are found on circuli on anterior and lateral regions of the scales in both fishes. It seems that focus shape, lepidonts and arrangement of cteni on the scales of those fishes could be used as important taxonomic features.
