En el presente estudio, se determinó la composición de la dieta de <em>P. argus </em>y la presión de depredación que ejerce sobre los gastrópodos de las regiones pesqueras Santa Cruz del Sur (SCrso) y golfo de Batabanó (GB), Cuba. Mediante arrastres se cuantificó la densidad y diversidad de gastrópodos, que, basado en la abundancia de langostas, sirvió para estimar el impacto de la depredación. Se capturaron 250 langostas: 62 en SCrso octubre 2012, 136 en el GB febrero 2014 y 52 en el GB julio 2018. La vacuidad fue similar en SCrso (38,7%) y en el GB (38,0%). Se registraron 13 categorías tróficas, las más frecuentes: opérculos (48,8%) y restos de crustáceos (48,0%), de conchas (47,2%) y vegetales (35,0%), demostrando que la dieta se compone principalmente de moluscos y crustáceos. La frecuencia de ocurrencia de vegetales sugiere consumo no accidental. Se identificaron 17 especies de moluscos, siendo <em>Tegula fasciata, Phrontis antillarum, Aliger gigas</em>, <em>Turbo castanea </em>y <em>Chione cancellata </em>las más frecuentes. La mayor tasa de depredación fue sobre las especies <em>T. fasciata </em>(3,36), <em>P. antillarum</em> (0,54) y <em>A</em><em>. gigas</em> (0,45)<em>. </em>La presión de depredación fue 0,92 gastrópodos langosta<sup>-1</sup> en SCrso y 3,31 gastrópodos langosta<sup>-1</sup> en el GB, lo que según las respectivas densidades de langostas (3.546 langostas km<sup>-2</sup> y 3.837 langostas km<sup>-2</sup>) y gastrópodos (3,76 ind. m<sup>-2</sup> y 1,45 ind. m<sup>-2</sup>), demostró que <em>P. argus </em>consume 0,087% de los gastrópodos en SCrso y 0,887% en el GB. Se encontraron además evidencias de canibalismo.","BibLvlCode":"AS","StandardTitle":"Tasa de depredación de <i>Panulirus argus</i> (Decapoda: Palinuridae) sobre moluscos gastrópodos en dos zonas pesqueras al sur de Cuba","OrigTitleLangCode":"es","OrigTitleLangCodeExtended":"spa","OrigTitleLangID":17,"DateLastModified":{"date":"2026-05-31 01:32:02.056396","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Langosta, decápodos, dieta natural, alimentación, moluscos, espectro trófico","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-10-19","DateCreate":"2022-10-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000863986100004","VABBcode":null,"OpenAcc":1,"DOI":"10.22370/rbmo.2022.57.1.3359"},"refs":null,"anarec":{"AnaID":356526,"PubliDate":2022,"Pagination":"34-44","XtraPublOfAnaID":null,"ISBN":null,"Volume":"57","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43879,"SerRR":"Revista de Biología Marina y Oceanografía.
