By embedding acoustic transmitters in baits and deploying them together with an automatic tracking system and cameras on the sea floor<sup>4,5</sup>, we have now tracked the speeds and directions of departing deep demersal scavenging fishes. At a series of stations between 4,000 and 6,000 m deep in the Northern Hemisphere, in contrasting trophic regimes, we have found that two closely related species of fish, <em>Coryphaenoides</em> (<em>Nematonurus</em>) <em>armatus</em> and <em><em>C</em>.(<em>N</em>.) yaquinae</em> have a significant role in bait dispersal. Even in remote oligotrophic locations, transmitters were consumed rapidly and were removed from the area of detection at a mean velocity of 0.11 m s<sup>&#x02212;1</sup>. We find that these fish are active foragers, constantly moving independently of bottom currents. This result is contrary to previous speculation of passive or drifting strategies<sup>6</sup> which might have been expected to conserve energy in a food-limiting environment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Direct measurement of active dispersal of food-falls by deep-sea demersal fishes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:48.619149","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1991,"MonPub":null,"DateUpdate":"2015-03-23","DateCreate":"2015-03-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1991FT11200064","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/351647a0"},"refs":null,"anarec":{"AnaID":245615,"PubliDate":1991,"Pagination":"647-649","XtraPublOfAnaID":null,"ISBN":null,"Volume":"351","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
