Lake sturgeon inogara munzvimbo dzemvura yakachena dziri kumahombekombe ekumabvazuva kweNorth America. Nguva zhinji hove idzi dzinopedzera kuzasi kwenzizi nemadziva, uko dzinodya zvipembenene, makonye, hozhwa, ma<em>crustaceans nedzimwe hove diki dzadzinobata, dzichisveta mvura yakawanda netsvina. Uku kunonzi kusveta kudya. Mhuka iyi parizvino inoonekwa seyaparara mumatunhu gumi nepfumbamwe pamakumi maviri ayo inowanikwa.
