Economic Importance for Humans: Positive
Threespine sticklebacks have been widely studied in terms of speciation and evolutionary history because of their phylogeny and adaptive radiations. Their abundance and the relative ease to cross, raise, and maintain in the lab make them an excellent animal model for a variety of studies. Threespine sticklebacks have also served as subjects in research on environmental effects since they are considered bioindicators.
