I want to test odor discrimination in a zebrafish model, but I don't know if there is a validated behavioral model to do that. If you can give me some hints, I would really appreciate it!
Yes there are some tests - they will depend on animal stages. See below articles using larvae, juveniles and adults. A frequently used test is the flume tank (there isone described in Gerlach's article). Hope this helps.
