In this study, scallop landings trends, export volumes and stock biomass are analysed for the entire Peruvian coastline and the role of El Niño and La Niña events for the productivity of the principal scallop banks is assessed. The study reveals that scallop landings and stock biomasses are well correlated for the principal banks of Independencia Bay, Lobos de Tierra Island and Sechura Bay. The scallop harvest from these banks was analysed taking into consideration the exploitation strategies used during the El Niño events of 1982/83 and 1997/98 and the possible impact of farming activities (“seed collection and scallop fattening”). Changes in the dynamics of the natural scallop banks in the Bay of Independencia and Lobos de Tierra Island during periods of El Niño and La Niña off the Peruvian coast are presented and discussed. Finally, considerations for the elaboration of a management plan for scallop stocks under conditions of climate variability and great spatio-temporal variations in local abundances are presented.","AbstractOtherLang":"La concha de abanico en Perú en la última década se ha convertido en uno de los moluscos de exportación más importante con fuertes fluctuaciones en los volúmenes desde el inicio de la exportación a inicios de los ochentas. En este trabajo se analizan las tendencias en los desembarques, los volúmenes de exportaciones y las biomasas de concha de abanico en la costa peruana durante las dos últimas décadas, y el rol que juega la ocurrencia de los eventos El Niño y La Niña en la producción de los principales bancos naturales. Los niveles poblacionales de los bancos en especial el de Bahía Independencia, Bahía de Sechura e Isla Lobos de Tierra correlacionan muy bien con los desembarques. La productividad de estos bancos es analizada considerando las diferentes estrategias de explotación durante los eventos El Niño 1982-83 y 1997-98 y el posible impacto de las actividades de cultivo (recolección de semillas y engorde). Los cambios de la dinámica de los bancos de Bahía Independencia e Isla Lobos de Tierra durante los periodos de El Niño y La Niña a lo largo de la costa peruana son presentados y discutidos. Finalmente se presentan algunas consideraciones básicas para la elaboración de un plan de manejo de la concha de abanico bajo condiciones de variabilidad climática y grandes variaciones espacio-temporales en la abundancia.","BibLvlCode":"AMS","StandardTitle":"Manejo y explotación de los principales bancos naturales de concha de abanico (<i>Argopecten purpuratus</i>) en la costa Peruana","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":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2009-04-09","DateCreate":"2009-04-09","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":133480,"PubliDate":2008,"Pagination":"101-114","XtraPublOfAnaID":null,"ISBN":"978-92-5-306115-0","Volume":"12","Issue":null,"BRefMon":133465,"BRefMonRR":"<b>Lovatelli, A.; Farías, A.; Uriarte, I.
