The structure of the Atlantic salmon retina corresponds to descriptions by previous workers and is also similar to that of the Pacific salmon retina. Retinal epithelial pigment light-adapts in 60 minutes. Cones light-adapt in 45 minutes. Dark-adaptation of the pigment and cones occurs in 70 minutes. Retinal index shows light-adaptation occurring in 60 minutes and dark-adaptation in 70 minutes. Results are compared with those of the Pacific salmon's.
