  • Ruditapes Decussatus) Exploitation in the Plentzia Estuary (Basque Country, Northern Spain)
    Modelling the management of clam (Ruditapes decussatus) exploitation in the Plentzia estuary (Basque Country, Northern Spain) Juan Bald & Angel Borja AZTI Foundation, Department of Oceanography and Marine Environment Herrera Kaia Portualdea z/g, 20110 PASAIA (Gipuzkoa) SPAIN Tel: +34 943 00 48 00 Fax: +34 943 00 48 01 www.azti.es [email protected] Abstract Some of the estuaries of the Basque Country (Northern Spain) have been areas of exploitation of clam populations, both by professional and illegal fishermen. There is a real possibility of overfishing and, therefore, the Department of Fisheries of the Basque Government needs to: (a) understand the situation relating to these populations; and (b) provide a tool to establish the most adequate management for the exploitation of clams. In order to simulate different alternatives for the exploitation, based upon scientific data on the population, the best tool available is a system dynamics model. Here the VENSIM® model was employed, utilising data on clam populations: summer stock and biomass in the Plentzia estuary, in 1998, 2000; winter stock in 1999, 2000, and 2001; the area occupied by the species; the length and weight class distribution; the number of fishermen; mean of biomass, captured by the fishermen; natural mortality, by length class; maturation; fertility rate; etc. This study improves previous experiences in modelling clam exploitation in the Plentzia and Mundaka estuaries. Following validation of the model, after running it for 1 and 10 years, some cases were simulated. This analysis was undertaken in order to establish the effect of modifying the number of fishermen, the aperture-close season of captures, the minimum sustainable biomass, the exploitation area and the minimum legal length for shellfishing.

  • Zuberoako Herri Izendegia
    92 ZUBEROAKO HERRI IZENDEGIA Erabilitako irizpideak Zergatik lan hau 1998an eskatu zitzaion Onomastika batzordeari Zuberoako herri izenak berraztertzea, zenbait udalek euskal izenak bide-seinaletan eta erabiltzeko asmoa agertu baitzuten eta euskaltzaleen artean ez izaki adostasunik izen horien gainean. Kasu batzuetan, izan ere, formak zaharkitu, desegoki edo egungo euskararen kontrakotzat jotzen ziren. Hori dela eta, zenbait herritan, Euskaltzaindiak Euskal Herriko udal izendegia-n (1979) proposatuari muzin eginik, bestelako izenak erabiltzen ari ziren. Bestalde, kontuan hartu behar da azken urteotan burutu lana, eta bereziki Nafarroako herri izendegia (1990) eta geroztik plazaratu “Nafarroako toponimia nagusiaren normalizaziorako irizpideak” Euskera, 1997, 3, 653-666. Guzti hori ezin zitekeen inola ere bazter. Onomastika batzordeak, Zuberoako euskaltzainen laguntza ezezik, hango euskaltzaleena ere (Sü Azia elkartearena, bereziki) eskatu zuen, iritziak hurbiletik ezagutzeko. Hiru bilkura egin ziren: Bilboko egoitzan lehendabizikoa, Iruñeko ordezkaritzan bigarrena eta Maulen hirugarrena. Proposamena Euskaltzaindiaren batzarrean aurkeztu eta 1998ko abenduan erabaki. Aipatu behar da, halaber, Eskiula sartu dugula zerrendan, nahiz herri hori Zuberoatik kanpo dagoen. Eztabaida puntuak eta erabilitako irizpideak Egungo euskara arautua eta leku-izenak Batzuek, hobe beharrez, euskara batuko hiztegi arrunterako onartu irizpide eta moldeak erabili nahi izan dituzte onomastika alorrean, leku-izenak zein bestelako izen bereziak, neurri batean, hizkuntza arruntaren sistematik kanpo daudela ikusi gabe. Toponimian, izan ere, bada maiz aski egungo hizkuntzari ez dagokion zerbait, aurreko egoeraren oihartzuna. Gainera, Euskaltzaindiak aspaldi errana du, Bergaran 1978an egin zuen biltzarraren ondoren, leku-- izenek trataera berezia dutela. Ikus, batez ere, kontsonante busti-palatalen grafiaz erabakia, Euskera 24:1, 1979, 91-92. Ñ letra hiztegi arruntean arras mugatua izan arren, leku-izenetan erabiltzen da: Oñati (G), Abadiño (B), Iruñea (N) eta Añana (A).

RESUMEN En un primer momento, los trabajos sobre el poblamiento altomedieval han adaptaron a los modelos planteados por los historiadores, investigando aquellos elementos considerados como “monumentales”, sin que se realizara conexión alguna con registros arqueológicos, con el paisaje o con otros testimonios que permitieran la interpretación e identificación de los procesos sociales y económicos que los habían generado. Por esto, en este trabajo queremos plantear un análisis sobre el estado de la cuestión, atendiendo a la reformulación de los plan- teamientos sobre los que se ha definido el poblamiento altomedieval hasta a fecha. Para ello, partiremos de un contexto más general para ir acercándonos al espacio geográfico que nos ocupa, Bikaia, heredera, sin duda, tanto de la situación europea como peninsular en esta materia. LABURPENA Erdi Aroko populatzearekin lotutakolana historialariek elementu “monumentalarekin” garatutako interpretzioarekin bat dator; erregistro arkeologiko, pasaia edo beste elemetu batzuekin eta haien prozesu sozialak eta ekonomikoen sortutako interpretazioa eta identifikazioare- kin lotura egin gabe.

  • Farm-To-Family / Adv. in Basque Country 2014
    BASQUE FAMILY BONDS Farm-to-Family Adventures in the Deep Heart of Basque Country 2014 Departures: July 27 and August 17 -- or as a private family departure any time Eight days exploring deep Basque Country, including: Bilbao, Ordizia, Mutriku, Zumaia, San Sebastian, Beizama and Bidegoian Trip Overview The first things that come to mind when asked to conjure up Basque Country may be the glittering Guggenheim or San Sebastian’s cult of culinary superstars. And while world class art & architecture and Michelin-starred restaurants are indeed fascinating features of this remarkable region, it’s the fierce independence of the region’s proud people, the dramatic diversity of its landscapes and the supreme importance placed on family, food and friends that leave their indelible mark on us. And through this lens of family-focused adventure, discovery and connection, we’ll enter deep into the heart of Basque culture. Whether milking sheep & making cheese on a small farm, navigating Bilbao from the perch of a paddleboard, hiking to a 17th C. farmstead for a home-hosted meal or gathered around the rustic wooden table of a cider house, we’ll experience Basque Country accompanied by local friends, exploring its natural grandeur and experiencing its most cherished family traditions. We’ve crafted this trip with families and their shared experience at its core. We’ve controlled the tempo, minimized travel times & hotel changes, built-in plenty of unstructured time and have even arranged for a parents’ night out. After all, at the heart of our Basque team are families that love to travel together, too – from my own, to our trip leader’s, to our favorite Basque ambassador and host, Pello, and his beautiful three generations of family that we’re fortunate enough to meet along the way.
