Over the last few years, regular sampling carried out on this scallop population has permitted experts to gather data on its reproductive cycle, abundance estimates and larval distribution. The authors have also studied the accumulation of postlarvae on a preferred natural substrate, the red alga <i>Rhodymenia</i> sp., as well as the effects of mass juvenile scallop seed collection using the Japanese-type collectors. Research carried out in the Reserve has focused on the management of the scallop populations and this has proved beneficial to the country. The primary goal has been to evaluate its potential as a constant, self-renewing source of seed scallops for use in aquaculture, since the area is well adapted for retention of larvae produced by the resident scallop population. Protective measures, aided by environmental conditions resulting from the 1997-98 ENSO (El Niño/Oscilación del Sur) events, promoted an increase in the natural banks from 6.1 x 106 scallops in 1997 to 11.3 x 106 individuals in 1999. In subsequent years however, oscillations in population numbers within the Reserve, due to illegal harvesting, have placed in doubt the continued success in the achievement of the primary goal stated above. The illegal extraction which affects these scallop beds has produced, similarly to that occurring in other (unprotected) Chilean scallop banks, a patent disregard for legislated national policy established for the protection and conservation of this marine resource. As noted, the application of harvesting restrictions on the commercialization of marine resources in Chile are not fully respected by the fishermen who, rather than following regulations designed to protect the resource and maintain it as a long-term renewable source of income, prefer to extract the more immediate economic benefits obtainable in the short-term.","AbstractOtherLang":"En septiembre de 1997, La Rinconada se convierte en la primera reserva marina de Chile, debido a su localización en el borde costero, a la significativa abundancia de <i>Argopecten purpuratus</i>, a las características biológicas de su población, y a las particulares condiciones hidrodinámicas del lugar. En los últimos años los muestreos regulares efectuados  sobre esta población de ostiones han permitido conocer detalladamente el desarrollo del ciclo sexual, estimar la abundancia y la distribución de las larvas, estudiar la fijación de las post-larvas sobre su sustrato predilecto, el alga roja <i>Rhodymenia</i> sp. e implementar la captación de semillas en colectores artificiales. Los estudios realizados al momento de constituir la reserva, para establecer medidas de conservación, indicaron que este sitio es una zona natural de retención larvaria y de asentamiento de postlarvas de <i>A. purpuratus</i>. Gracias a este fenómeno, a las medidas de protección, y a la ocurrencia de un evento ENSO (El Niño/Oscilación del Sur) entre 1997-1998, la población se incrementó de 6.1 x 106 ejemplares en 1997, a 11.3 x 106 en 1999. Sin embargo, en años posteriores el número de ejemplares de esta reserva, ha variado debido a la extracción clandestina, que afecta a este banco, lo que ha impedido al igual que ocurre con bancos no protegidos en Chile, que las medidas de regulación impuestas por el Estado sobre el recurso, tengan los efectos deseados, demostrando, que el interés económico de corto plazo impuesto por las demanda, primaría sobre una conciencia de protección racional de más largo plazo.","BibLvlCode":"AMS","StandardTitle":"Aspectos biológicos y poblacionales de <i>Argopecten purpuratus</i> en la reserva marina La Rinconada: contribución para su manejo","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","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":133502,"PubliDate":2008,"Pagination":"249-266","XtraPublOfAnaID":null,"ISBN":"978-92-5-306115-0","Volume":"12","Issue":null,"BRefMon":133465,"BRefMonRR":"<b>Lovatelli, A.; Farías, A.; Uriarte, I.
