Abstract:

The histological, surface and internal fine structures of gill of Liza haematocheila were investigated using light, scanning and transmission electron microscopy. The results showed that there were 4 pairs of holobranch in Liza haematocheila, and each gill filament was consisted by branchial arch, primary filament, secondary filament and gill raker. The surface structure and ultrastructure of gill filaments and secondary gill lamellae of L. haematocheila were similar to other teleosts. The surface of primary filament had various features such as regular or irregular circular microridges, indentations, micropits and crevices. The primary filaments were separated into respiratory area and non-respiratory area. The respiratory area of filaments was smooth with no microridge but folded on the epithelial cells membrane. Various features such as indentations, micropits and crevices were observed on non-respiratory area of filaments with regular fingerprint shape microridges on epithelial cells. The secondary filaments, which functioned as the main organ of respiratory, were consisted of basement membranes, epithelial cells, endothelial cells, pillar cells and capillary vessels. Chloride cells were mainly found in base part of secondary filament, and they often seemed to be open at the surface between adjacent epithelial cells. The relationship between the structure and function of fish gill in L. haematocheila was also discussed.
