AB  - Present study reports significant modifications in surface ultrastructure, 
      histological organization, and histochemical localization of glycoproteins (GPs) 
      in the gills of a hill stream catfish, Hara hara. Punctate microridges on free 
      surface of epithelial cells covering gill arches, gill rakers, gill filaments and 
      secondary lamellae are considered to provide adaptive plasticity to gills in 
      relation to the environment inhabited by fish. Short and stout gill rakers are 
      considered to prevent food particles to pass in opercular chamber along with 
      respiratory current that could damage delicate gill filaments. Mucous goblet 
      cells show presence of different classes of glycoproteins. GPs with oxidizable 
      vicinal diols are considered to control acidity of acidic GPs. GPs with carboxyl 
      groups have been implicated with defensive mechanism against microorganisms. GPs 
      with O-sulphate esters are associated to trap and to lubricate food particles for 
      easy swallowing. Taste buds on gill arches and gill rakers function to select 
      palatable food particles. Occurrence of taste buds on the gill filaments is 
      regarded significant adaptation to analyse the chemical nature of water. This 
      study could play a significant role to understand adjustment of gills in the hill 
      stream fish.
