A bstract : Scotopic electroretinogram of dogfish shark ( Scylliorhinus canicula ) and eel ( Anguilla anguilla ) is characterized by a negative off‐response, changing in sign under photopic condition. It increased under the effect of increased background illumination, but its amplitude never exceeded that of the b‐wave. On the other hand, dark‐adapted electroretinograms of two perch‐like species, perch ( Perca fluviatilis ) and painted comber ( Serranus scriba ), exhibited a positive off‐wave, exceeding the b‐wave amplitude under bright photopic conditions.
