Opercular epithelial cells ofFundus heteroclituswere investigated using conventional microelectrodes. The area of interest was the cells lining the inside of the opercular epithelium closest to the gill arches, an area with a high density of chloride cells. Only one cell type could be discerned from the values of 60 opercular cells measured with the opercular epithelium in open circuit conditions. A mean apical voltage of −18.0 ± 0.6 mV was observed with intracellular values ranging from −10 to −30 mV. The predicted intracellular chloride content was 59 mM/liter. Apical fractional resistance (f) was 0.78 ± 0.02. The intracellular potential measurements were typically difficult to maintain for extended periods (longer than 3 min). The opercular cells depolarize with serosal isoproterenol treatment (10−6M) corresponding to the increase in opercular transepithelial potential. The opercular cell apical fRdecreased with isoproterenol treatment. These data indicate the observed opercular cells were involved in opercular chloride transport.
