A shrimp fishery, which is not permitted to expand, alsooperates. We analyzed various harvesting strategies with the Ecopath with Ecosim modelling software, using catch-and-effortdata for target species to fit simulated biomasses. Optimal harvesting strategies for artisanal fisheries were explored using social,economic and ecological criteria. Several harvesting strategies were simulated: continuation of the current state of the fisheries,optimizing economic and social (employment) criteria, using maximum sustainable yield (MSY) as a goal of management, andoptimization of an ecological criterion when necessary. Optimization of current fisheries and economic and social criteria, and theMSY resulted in depletion of some stocks and in no-realistic increases in fishing effort. Combinations of economic-ecological,social-ecological and economic-social-ecological criteria did not result in stock depletion. However, some of these scenariosresulted in unrealistic choices, especially large increases in gillnet fishing effort. Among the reasonable choices, a strategy ofincreasing the hook-and-line fishery effort by a factor of 1.5 and the gillnet effort by a factor of 2.8, appeared to be potentiallyapplicable, to increase efficiency of the artisanal fisheries.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Optimal management scenarios for the artisanal fisheries in the ecosystem of La Paz Bay, Baja California Sur, 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":"Ecopath with Ecosim; Optimization","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2004-02-13","DateCreate":"2004-02-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000189226500016","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":57427,"PubliDate":2004,"Pagination":"373-382","XtraPublOfAnaID":null,"ISBN":null,"Volume":"172","Issue":"2-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42623,"SerRR":"Ecological Modelling.
