Spatial response of adult zebrafish to ecologically relevant odorants. Average occupancy maps representing the swim location of zebrafish during odor exposure (n = 10 zebrafish, see the “Methods” section) in response to a food-related odors in green (food extract, nucleotides, histidine, methionine, phenylalanine, cysteine, and arginine), b social-related odors in blue (prostaglandin 2α, bile acids, urea, and ammonium), c decay odors in magenta (putrescine, spermine, cadaverine), d alarm odors in red (chondroitin sulfate, zebrafish blood, zebrafish skin extract), and e water control in black. The numbers located under the odor label for maps in a–e refer to the spatial correlation (mean ± SEM) of individual maps to the average occupancy map (spatial stereotypy). f Average of all food odor maps in a. g Average of all social odor maps in b. h Average of all alarm odor maps in c. i Average of all decay odor maps in d
