Using integrated hydroacoustic surveys, deep towed camera imagery and physical sampling from 2023 to 2025, we quantified the spatial and temporal dynamics of these assemblages and produced species-specific biomass estimates. Acoustic backscatter attribution followed a two-phase approach: (i) camera-derived species distributions to inform spatial apportioning of backscatter and (ii) conducting biomass-constrained sensitivity analyses applying conservative bounds on orange roughy biomass (200\u2013850 t) informed by historical assessments. We found a large, seasonally variable basketwork eel aggregation that increased markedly from March to May, when biomass reached 3547\u20133557 t (approx. 2.8 million individuals), likely corresponding to spawning. Distinct habitat preferences\u2014with basketwork eels on deeper, flatter terrain and orange roughy on steep summit slopes\u2014improved spatial separation of backscatter in this mixed-species environment. Without biomass constraints, orange roughy estimates became implausible relative to regional stock assessments, underscoring the need for species discrimination in deep-sea acoustic analyses. Patience Seamount's protection and recovery from historical fishing provide a rare opportunity for long-term study of deep-sea ecological processes. Our methods offer a scalable, non-invasive framework for monitoring deep-sea aggregations in marine protected areas.<\/jats:p>","DOI":"10.1098\/rsos.260397","type":"journal-article","created":{"date-parts":[[2026,10,28]],"date-time":"2026-10-28T05:29:07Z","timestamp":1793165347000},"source":"Crossref","is-referenced-by-count":0,"title":["A unique ecological phenomenon quantified by hydroacoustics: the deep-sea eel spawning aggregation at Patience Seamount"],"prefix":"10.1098","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9358-736X","authenticated-orcid":false,"given":"Ben","family":"Scoulding","sequence":"first","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Gastauer","sequence":"additional","affiliation":[{"name":"Th\u00fcnen Institute of Sea Fisheries 3 , Bremerhaven, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlie","family":"Devine","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franziska","family":"Althaus","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alistair","family":"Hobday","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Farley","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruce","family":"Deagle","sequence":"additional","affiliation":[{"name":"NCMI, Commonwealth Scientific and Industrial Research Organization 2 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Pogonoski","sequence":"additional","affiliation":[{"name":"NCMI, Commonwealth Scientific and Industrial Research Organization 2 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Gorton","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Downie","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Williams","sequence":"additional","affiliation":[{"name":"Environment, Commonwealth Scientific and Industrial Research Organization 1 , Hobart, Tasmania, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2026,10,28]]},"reference":[{"key":"2026102801285996900_RSOS260397C1","doi-asserted-by":"crossref","first-page":"413","DOI":"10.1002\/9780470691953.ch19","volume-title":"Seamounts: ecology, fisheries & conservation","author":"Clark","year":"2007"},{"key":"2026102801285996900_RSOS260397C2","doi-asserted-by":"crossref","first-page":"3533","DOI":"10.1098\/rspb.2010.1057","article-title":"The dynamics of biogeographic ranges in the deep sea","volume":"277","author":"McClain","year":"2010","journal-title":"Proc.
