Abstract：
:In the retina of Siberian sturgeon, three spectral classes of photoreceptors were identified by microspectrophotometry. These were rods, oil drop-containing and oil drop-free cones possessing P549, and oil drop-containing cones possessing P613 and P465. With intracellular recordings, rod-driven, cone-driven, and mixed horizontal cells of luminosity type were found, as well as color-opponent horizontal cells of, at least, 6 kinds. Biphasic R/G cells received hyperpolarizing input either from rods or from green cones; in R/B cells, it was from blue cones. Other three types comprised biphasic G/B (or Y/B), RG/B, and triphasic G/BR cells. So the Chondrostean retina has the color-processing circuitry common for all ray-finned fishes.
