Their<br>diversity in the WIO is amongst the highest globally yet few studies have assessed the occur-<br>rence of various species in catches. Demersal trawl catches from Kenya, Tanzania, Mozambique,<br>Madagascar and South Africa (East Coast) were analysed using Generalised Linear Models to esti-<br>mate the probabilities of non-zero catches of sharks and batoids. The data were further subjected<br>to non-metric multidimensional scaling to establish clusters of various communities and to sim-<br>ilarity percentage analyses to determine the dominant taxa. The probability of catching sharks<br>and batoids in trawl nets was high. While communities were not highly separated within factors,<br>it was depth that showed the greatest influence on community structures. The genus Squalus dom-<br>inated the shark catches as depth increased while species dominance of batoids changed from<br>stingrays (Dasyatidae) to guitarfishes (Rhinobatidae) and to skates (Rajidae) as depth increased.<br>This study underlines the need for improved species identification of elasmobranch catches and<br>for marine protected areas on soft sediment habitats to protect these important species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Patterns in the occurrence of elasmobranchs in demersal trawl catches in the Western Indian Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-04 01:31:56.637957","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"elasmobranchs, sharks, batoids, diversity, demersal trawling","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-10-03","DateCreate":"2025-10-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.4314/wiojms.si2025.1.5"},"refs":null,"anarec":{"AnaID":418725,"PubliDate":2025,"Pagination":"67-86","XtraPublOfAnaID":null,"ISBN":null,"Volume":"Spec.
