The Effect of Synthetic Scotophobin on the Light Tolerance of Teleosts (Carassius Auratus and Tinca Tinca)
Groups of goldfishes and tenches were kept in a light-dark choice aquarium. After intracranial injections of synthetic scotophobin the light tolerance of both species was found to be increased, whereas injections of Ringer solution into control animals did not change their behavior.
