This fish causes hallucinations when eaten and were used as a recreational drug by the Roman Empire.

Salema porgy, is a species of bream, recognisable by the golden stripes that run down the length of its body, and which can cause hallucinations when eaten. It is relatively common off the coasts of South Africa, Tenerife, Malta and Cyprus, but has been occasionally been found as far north as Great Britain.

Sarpa salpa was reportedly consumed as a recreational drug during the time of the Roman empire. The fish became widely known for its psychoactivity following widely publicized articles in 2006, when two men ingested it at a Mediterranean restaurant and began to perceive many auditory and visual hallucinogenic effects. These hallucinations, described as frightening, were reported to have occurred minutes after the fish was ingested and had a total duration of 36 hours.

Ichthyoallyeinotoxism, or hallucinogenic fish poisoning is common in other species of fish but not in Sarpa salpa, which is not normally psychoactive. It is, in fact, often served as a dish at seafood restaurants in the Mediterranean area. It is presently believed that the fish ingests a particular algae or phytoplankton which renders it hallucinogenic. The effects described are similar to those of indole tryptaminepsychedelics.
