Growth at moulth, intermoult period and moulting seasonality of the spider crab "Maja brachydactyla" : combining information from mark-recapture and experimental studies
Corgos López-Prado, Antonio; Sampedro Pastor, María Paz; González-Gurriarán, Eduardo; Freire, Juan (2005)[Abstract] An analysis of growth at moult (for both the prepubertal and terminal moults), moulting seasonality and the intermoult period in the spider crab Maja squinado in the Ría de A Coruña (NW Spain) was carried out ... -

Hierarchical organization of spatial and temporal patterns of macrobenthic assemblages in the tropical Pacific continental shelf
Godínez Domínguez, Enrique; Freire, Juan; Franco-Gordo, María del Carmen; González Sansón, Gaspar (2002)[Abstract] 1. Nowadays, studies focused to test a well-defined set of a priori hypotheses about spatial and temporal organization of assemblages in marine communities are scarce. 2. This study presents the first ... -
Impacto del Prestige sobre recursos pesqueros y marisqueros
Freire, Juan (2003) -
Information-theoretic approach for selection of spatial and temporal models of community organization
Godínez Domínguez, Enrique; Freire, Juan (Inter-Research, 2003)The literature on the ecology of marine assemblages includes frequent examples of data analysis with no well-defined alternative hypotheses for the definition of environmental variables (independent matrix for multivariate ... -
Integration of fishers’ ecological knowledge in fisheries biology and management : a proposal for the case of the artisanal coastal fisheries of Galicia (NW Spain)
Freire, Juan; García Allut, Antonio (International Council for the Exploration of the Sea, 1999)The fisheries crisis of the last decades and the overexploitation of a great number of stocks have revealed that the scientific knowledge available about the dynamics of the marine ecosystems and needed for the management ... -
Inter-specific comparative analysis of distribution and habitat use patterns of benthic decapod crustaceans in shallow waters
Pallas Lozano, Alicia; García Calvo, Beatriz; Corgos López-Prado, Antonio; Bernárdez Martí, Cristina; Freire, Juan (2005)[Abstract] Coastal areas have been widely considered as nurseries for many marine species. New approaches to this concept take into account interactions among environmental variables and ecological variations related to ... -

Interactions of the fishery of the spider crab Maja squinado with mating, reproductive biology and migrations
Freire, Juan; Fernández, Luis; González-Gurriarán, Eduardo (1998)[Abstract] In this paper different aspects of the fishery and life history of the spider crab Maja squinado in southern Galicia (NW Spain) are analyzed to evaluate the potential effects of the fishery on the sperm limitation ... -
Interannual variability of the diversity and structure of ichthyoplankton assemblages in the central Mexican Pacific
Franco-Gordo, María del Carmen; Godínez Domínguez, Enrique; Freire, Juan (2004)[Abstract] We examined larval fish diversity and assemblage structure on the central Mexican Pacific (coast of Jalisco and Colima) using data from samplings carried out with a Bongo net at 12 stations during 27 months, ... -
IT as agent of social change : "Lonxanet" and the case of the galician artisanal fisheries
Dans, Enrique; Freire, Juan (Association for Information Systems, 2002)[Abstract] Information technologies (IT) can be used as an agent to foster social change. This case study describes an Internet start-up, Lonxanet, and analyzes its potential role as a catalyst of changes in the Galician ... -
Main effects of the 1997-1998 ENSO event in the tropical coastal ecosystem in the Mexican central Pacific

Management strategies for sustainable invertebrate fisheries in coastal ecosystems of Galicia (NW Spain)
Freire, Juan; Bernárdez Martí, Cristina; Corgos López-Prado, Antonio; Fernández, Luis; González-Gurriarán, Eduardo; Sampedro Pastor, María Paz; Verísimo Amor, Patricia (Kluwer Academic Publishers, 2002)Artisanal coastal invertebrate fisheries in Galicia are socio-economically important and ecologically relevant. Their management, however, has been based on models of fish population dynamics appropriate for highly mobile ... -
Megabenthic decapod crustacean assemblages on the Galician continental shelf and upper slope (north-west Spain)
Fariña Pérez, Antonio Celso; Freire, Juan; González-Gurriarán, Eduardo (Springer-Verlag, 1997)The structure of megabenthic decapod crustacean assemblages on the Galician (north-west Spain) continental shelf (100 to 200 depth) and upper slope (200 to 500 m) was analyzed based on surveys carried out in autumn and ... -
Metapopulation dynamics in the spider crab "Maja squinado" : implications for fisheries management

García Allut, Antonio; Freire, Juan; Barreiro García, Álvaro; Losada Carril, David Enrique (Fisheries Centre Research Report, University of British Columbia, 2003)[abstract] The fisheries crisis of the last decades and the overexploitation of a great number of stocks (FAO 1995) have been due mainly to the inadequacy of scientific knowledge, uncertainties in assessments and/or failures ... -
Movements of juvenile and adult spider crab ("Maja squinado") in the Ría da Coruña (NW Spain)
