From 148 demersal trawl samples, distributed over 15 locations, 98 fish species were identified. <i>Stellifer rastrifer, Amphiarius rugispinis</i> and <i>Cynoscion jamaicensis</i> represented 50 % of the catches. Cluster analysis revealed three species assemblages, occurring in a nearshore-offshore depth gradient. A <i>coastal</i> fish assemblage occurred in the shallow turbid waters, characterised by muddy sediments with relatively high organic carbon content. A <i>transition</i> assemblage around 27 m water depth marked the shift towards a very different <i>offshore</i> fish assemblage on the deepest sampling locations (34 m), which were characterised by coarser sediments, with clear overlying waters. The <i>coastal assemblage</i> represented the ‘sciaenid community’; of tropical shelves, dominated by Sciaenidae and Ariidae. The <i>offshore assemblage</i> had a significantly lower fish density and diversity, and contained representatives of fish families typical for deeper tropical shelves, such as Paralichthyidae, Triglidae and Lutjanidae. The shift between the <i>coastal</i> and <i>offshore</i> fish assemblage was the most important feature of the demersal fish community, and coincided with a transition between two principal ecosystems: a coastal, river influenced system fuelled by detritus versus an open shelf system based on primary production. Whereas pelagic fishes are known to gain in importance on the open shelf, demersal fishes thrived in the coastal ecosystem, together with a potentially important epibenthic food source, the Atlantic seabob shrimp <i>Xiphopenaeus kroyeri</i>. In Suriname, large demersal (mainly sciaenid) fishes are the main fisheries resource for the artisanal fleet in the nearshore waters below 20 m depth. Because juveniles of commercially important fishes were abundant in our <i>coastal</i> trawl catches, we suggest the shallow nearshore waters have a main nursery function.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Distribution patterns of the demersal fish fauna on the inner continental shelf of Suriname","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Tropical; Inner continental shelf; Soft bottom; Demersal fish community","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2016-06-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000414754700020","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.rsma.2015.10.008"},"refs":null,"anarec":{"AnaID":259095,"PubliDate":2015,"Pagination":"177-188","XtraPublOfAnaID":null,"ISBN":null,"Volume":"2","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":259094,"SerRR":"Regional Studies in Marine Science.
