The Ecopath with Ecosim software was used to simulate harvesting strategies aimed at optimizing economic (profit),social (jobs), ecological (conservation of ecosystem structure) and shrimp-recovery criteria. As expected, the ecosystem changesthat would ensue vary according to the combination of optimization goals. We found that for some scenarios, the extractionof biomass from a discrete trophic-level changes impacting ecosystem and catch structure. This was clearly observed throughthe tendency of the mean trophic level of the ecosystem and catch, as well as the fishing-in-balance index (FBI). A particulardiscussion was made about the collapsed shrimp fishery, where the impact of a specific shrimp-recovery strategy was evaluated.Collapse is strongly associated to physical variables and recovery based on trophic relationships is plausible but with a highecosystem structure cost.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Simulated response to harvesting strategies in an exploited ecosystem in the southwestern Gulf of Mexico","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Ecosystem response; Harvesting strategies; Shrimp collapse; Gulf of Mexico","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2004-02-13","DateCreate":"2004-02-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000189226500019","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":57432,"PubliDate":2004,"Pagination":"421-432","XtraPublOfAnaID":null,"ISBN":null,"Volume":"172","Issue":"2-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42623,"SerRR":"Ecological Modelling.
