The photoreceptors and eyes of four fish species commonly cohabiting Fennoscandian lakes with different light transmission properties were compared: pikeperch Sander lucioperca , pike Esox lucius , perch Perca fluviatilis and roach Rutilus rutilus . Each species was represented by individuals from a clear (greenish) and a humic (dark brown) lake in southern Finland: Lake Vesijärvi (LV; peak transmission around 570 nm) and Lake Tuusulanjärvi (LT; peak transmission around 630 nm). In the autumn, all species had almost purely A2‐based visual pigments. Rod absorption spectra peaked at c .526 nm ( S. lucioperca ), c . 533 nm ( E. lucius ) and c . 540 nm ( P. fluviatilis and R. rutilus ), with no differences between the lakes. Esox lucius rods had remarkably long outer segments, 1.5–2.8‐fold longer than those of the other species. All species possessed middle‐wavelength‐sensitive (MWS) and long‐wavelength‐sensitive (LWS) cone pigments in single, twin or double cones. Rutilus rutilus also had two types of short‐wavelength sensitive (SWS) cones: UV‐sensitive [SWS1] and blue‐sensitive (SWS2) cones, although in the samples from LT no UV cones were found.
