2.8 million eels gather at one Tasmanian seamount — and science finally has a baseline to protect them

Off Tasmania, at a lonely underwater mountain called Patience Seamount, researchers estimate about 2.8 million basketwork eels — some 3,500 tonnes of them — gather to spawn, fasting and packed almost fin-to-fin. The species is listed as vulnerable globally, and a survey on one New Zealand continental slope recorded an 85% decline over 40 years, which is exactly why a solid count at Patience matters: you cannot protect what you have not measured. There is already a concrete safeguard — a management plan introduced in 2025 protects the seamount from bottom trawling, Parks Australia confirms. Protection is not proof of recovery, and scientists are careful not to claim it. But now there is a number, a protected breeding site, and a reason to come back and count again.
