Lysergic acid diethylamide (LSD 25): II. Psychobiological effects on the Siamese fighting fish
Science, (1954)Abstract
Four groups, each consisting of four Siamese fighting fish, were exposed for six hours to four different concentrations of lysergic acid diethylamide (LDS 25), 1 mu g/ml, 5 mu g/ml, 25 mu g/ml, and 50 mu g/ml dissolved in spring water, and compared with controls. Controls were "normal," but the remaining four groups after being removed from the drug at first displayed a stupor like state, with complete recovery occurring for the low dose group within a day and for the high dose group within a week. The authors suggest that their " . . . technique provides a new bioassay method for LSD 25 and possibly other ergot drugs." (PsycINFO Database Record (c) 2004 APA, all rights reserved)
