Two threatened marine species urgently need sustainability assessments before future wild harvests are conducted for public aquarium displays, a Charles Darwin University researcher warns.

PhD candidate Kate Buckley has devised a new three-step approach to inform relevant authorities of the need for sustainability assessments before permitting the removal of threatened, or data-deficient and potentially threatened, shark and ray species (elasmobranchs) from the wild.

She said the Critically Endangered Largetooth Sawfish and the Vulnerable Grey Nurse Shark were high priorities as they were at risk of extinction, did not currently breed in captivity, and future wild harvests were proposed.
