Microscopic Observation on Gill Structure of Juvenile Pseudosciaena crocea under Different Salinities

Ruanchengxu , Yuanchonggui and Wudefeng

Abstract:
The characteristics and differences of gill structure of juvenile pseudosciaena crocea under different water salinities are studied through electron microscopic observation. Results show that the structures of gill of juvenile pseudosciaena crocea are similar to those of other teleosts. When the salinity of water is at 6°, the epithelia cells on secondary filament of juvenile Pseudosciaena crocea are smooth, the number of chloride cells are less than that of high salinities, the number of mitochondria and tubular network of chloride cells are also few. When the salinity of water is at 16°, the epithelia cells on secondary filament of juvenile Pseudosciaena crocea are less smooth, the number of chloride cells will be increased. It can be found that chloride cell combined with accessory cells are turned into the multicellular compleses, the number of mitochondria is increased and the mitochondrial cristae and tubular network became more complicated; when the salinity of water is at 26°, the epithelia cells on secondary filament of juvenile Pseudosciaena crocea are not smooth, the number of chloride cells is abundant and is mainly located in the secondary filament part, many chloride cell combined with accessory cells forms the multicellular compleses, the number of mitochondria is numerous, the mitochondrial cristae and tubular network are also complicated.
