Oceans are in serious trouble for several reasons, not the least of which is unsustainable fish-ing (Hutchings 2000, Jackson et al. 2001, Pauly et al. 2002, USCOP 2004, Worm et al. 2006). Separating the effects of pollution, invasive spec-ies, diseases, and ocean warming from fishing is critical, if resource managers are to move beyond reactively treating symptoms of stress to address-ing the underlying causes of degradation.
