Kudzorerwa kunosiyana-siyana munzvimbo nenzvimbo, uye huwandu hweblue whale yekumabvazuva kweNorth Pacific (nhoroondo chikamu chidiki chehuwandu hwepasi rose) hwadzoka kune vanhu vanosvika zviuru zviviri nemazana maviri, inofungidzirwa kuti 97% yevanhu vayo vasati vavhima.Huwandu hwepasi rose hwaive pakati pezviuru zvishanu nezviuru gumi nezviviri muna 2002; kune huwandu hwakanyanya hwekusava nechokwadi mukufungidzira kuripo kwenzvimbo zhinji. Imwe fungidziro ichangobva kuitwa neIUCN inotaura kuti pasi rose kune vanhu vanenge 10 000 kusvika ku25 000. IUCN Red List inotaura kuti blue whale "iri mungozi yokuparara", sezvave zvichiitika kubvira pakatanga rondedzero yacho.
