In a 1997 report about saving the bluefin tuna, the World Wide Fund for Nature noted that the southern bluefin tuna, as a result of overfishing, was already facing "commercial extinction" (meaning that commercial fishing of it was no longer viable).
一九九七年，「世界保護自然基金會」發出一份黑鮪的求救報告，南方黑鮪因為捕撈過度，已經面臨「商業絕種」（捕撈難以為繼）。
