GROUP OUTLINE

The Marine Genetic Resources Laboratory (ReXenMar) was created by Pablo Presa (1999) after being hired by the University of Vigo (1997). The group size fluctuated between three and ten members in the last two decades upon collaborative projects, regional scientific priorities and the fluctuating policy of the University Administration. Currently, the team consists of six researchers specialized in marine genetics and aquaculture and belongs to the Singular Center of Marine Research (CIM-ECIMAT). On an individual basis, ReXenMar researchers cooperate preferentially  with the Spanish IEO as well as with foreign research institutions of similar research interests, e.g. UANTOF-CHL, UMAG-CHL, IMARPE-PE, CIIMAR-POR, UAZORES-POR, UNJBG-PE, INIDEP-ARG.

RESEARCH INTERESTS

ReXenMar is formed by enthusiastic scientists bearing expertise in the following applied fields:

1. Fisheries genetics. ReXenMar develops genetic investigations aiming to decipher the role of demographic connectivity in the maintenance of genetic structures in marine species and how such genetic information can be integrated in the management of fisheries for sustainability.

2. Fisheries forensics. ReXenMar has calibrated several DNA-based probes and phylodiagnostic approaches to identify fish samples and their likely geographical origin. Such information can be ecumenically applied in fisheries forensics, commercial traceability and fraud detection, hybridisation, migration ecology and seasonally-dependent distribution patterns of species.

3. Genetics in aquaculture. ReXenMar is competent in the genetic evaluation of candidate especies for aquaculture, genetic management under domestication, optimisation of nutritional and reproductive designs, and genetic improvement of quantitative traits.

Such expertise has been mainly developed on the European hake (Merluccius merluccius), the Mediterranean mussel (Mytilus galloprovincialis) and the common octopus (Octopus vulgaris), although additional research challenges are currently being addressed in demersal fishes and coastal mollusks.
