Titulo : Towards a genetic informed management in hake and anglerfish?
Abstract:
Achieving a sustainable fisheries management relies on an appropriate assessment of fish resources which, in turn depends on a correct definition of management units.
The success of fisheries management relies on an accurate fisheries assessment, that is, the synthesis of information on life history, fishing activity and resource surveys for estimating the current, and predict the future, status of fisheries. In turn, accuracy of fisheries assessment relies on a correct definition of management units (stocks), which are assumed to constitute naturally isolated populations whose parameters such as growth, recruitment and natural and fishing mortality are intrinsic and not dependent emigration or migration rates. Failure to match administrative and biological units could result in infeasibility to establish an accurate relationship between productivity and harvest rates and can result in local reduction of populations and, in extreme cases, to local population collapse. Yet, although, genetic analyses have revealed mismatches between biological and management units, which are often defined upon political and administrative considerations, the uptake of genetic methods by the fisheries assessment process is not yet a reality. Here, I will address this issue using the European hake and the white/black anglerfish as case studies. Using genome-wide single nucleotide polymorphism (SNP) markers, we have found conservation and management important phenomena such as mismatches between administrative and natural populations, interspecific hybridization, mislabeling and genetic adaptation. We will discuss the potential impact of these new findings on species management and conservation and review the lessons learnt from the course of communicating and integrating genomic data into fisheries assessment.
Biografía:
PhD in Biochemistry from the University of Montréal, Canada) has 25 years of experience in molecular ecology and evolution, population genomics, large-scale sequence data generation and analysis, and bioinformatics. After several postdoctoral stays in UK and Spain working in a variety of projects, since 2011 she works at AZTI, where she currently leads the Biotechnology and Molecular Ecology research area. Dr. Rodríguez-Ezpeleta has participated in numerous international and national projects dedicated to the application of genetics for improving marine management and is an active member of several expert groups of the International Commission for the Exploration of the Sea (ICES) and the International Commission for the Conservation of Atlantic Tunas (ICCAT), chairing some of them. She has been invited to speak at international conferences and seminars and is advisor of the environmental DNA expeditions in UNESCO World Heritage Marine Sites. Dr. Rodriguez-Ezpeleta has published articles in high impact journals and books and is editor of Molecular Ecology and Molecular Ecology Resources.
