This ray is commonly taken where heavy artisanal and small-scale commercial fisheries occur in or around coral reef habitats. Additionally, it may possibly be exploited locally for capture for the marine aquarium trade. It is at risk in many areas because of its dependence on coral reef habitats. These are under massive assault from net, dynamite and cyanide fisheries for teleosts in many places where the species occurs. In East Africa, artisanal fishers catch T. lymna using bottom¬set gillnets, longlines and skin-diving with spears, and also as bycatch in fence traps (S. Yahya and N. Jiddawi pers. obs.). Habitat loss and degradation therefore likely exert a significant impact on populations.
