This study compared the contribution of the Ca 2+ ‐activated Cl − conductance to the electroolfactogram ( EOG ) evoked by different odorant classes between the marine Cabinza grunt Isacia conceptionis and rainbow trout Oncorhynchus mykiss . The Ca 2+ ‐activated Cl − channel blocker niflumic acid significantly diminished odorant responses in O. mykiss , but had no effect on the EOG in I. conceptionis , supporting the notion that Ca 2+ ‐activated Cl − channels may not operate as odorant transduction current amplifiers in this marine teleost.
