Abstract
In the silver eel (A. anguilla) maintained in fresh water, surgical removal of Stannius corpuscles (SC) resulted in a significant increase of wet weight of gill cells and the dry weight of gill filaments expressed as a function of body weight; a proliferation and a hypertrophy of chloride cells shown by a significant rise of cell volume expressed as a percentage of the epithelial volume; and an increase of the Ca binding protein activity in the total branchial mucosa. These modifications are not observed when eels are maintained in Ca-free water. The results are discussed in relation to the Ca fluxes across gills in eels deprived of SC and gill morphological changes during sea water adaptation.
