Abstract

Abstract:

Objective To study the microscopic structure and ultrastructure of gill of juvenile Pseudosciaena croceafor more abundant reference of breathing and salinity adaptation physiology. Methods The microscopic structure and ultrastructure of gill of juvenilePseudosciaena crocea were observed by light and transmission electron microscopic. Results The structures of gill of juvenilePseudosciaena crocea were similar to those of other teleosts, the comb primary filaments lined on the gill, and secondary gill lamellae inlaid on two sides of each filament. Secondary filaments consisted of epithelial cells, endothelial cells, pillar cells and capillary vessel net. Chloride cells were found both in the secondary filaments and the base. In the base of the secondary filaments, the number of chloride cells were more. Inside the cells there were tubular network and abundant mitochondrias. Conclusion The structures of gill of juvenilePseudosciaena crocea were similar to those of other teleosts. The features of the structure of gill maybe can explain whyPseudosciaena croceahave strong adaptability to salinity.

Key words: Gill, Salinity, Light microscope, Transmission electron microscope, JuvenilePseudosciaena crocea
