The general aim of the group is to acquire knowledge and to develop the instruments needed for the suitable implementation of an ecosystem-based approach to living marine resources management.
AREAS OF RESEARCH
- Management of living marine resources
- Nowadays there is a trend to emphasise the study of changing patterns in the distribution and abundance of cephalopods larvae, especially the ones of common octopus Octopus vulgaris and of common squid, Loligo spp. in Galician coasts, quantifying the meteorological, physical and biochemical conditions where fishing of larvae is performed, and estimating, by indirect methods, the primary production and the transference to higher trophic levels.
- The trophic ecology of early stages of marine resources and their potential prey is also studied, focusing in zooplankton organisms.
- We work on identification, delimitation and estimation of the abundance of currently exploited and potentially exploitable populations and on the spatial-temporal variability of populations and their cohorts employing survey data and predictive models, the latter being based on the short and long term relationship between stock abundance and atmospheric-oceanic parameters obtained by remote sensing and oceanographic campaigns.
- We study the recruitment, growth, age, reproductive parameters and feeding behaviour of the species, as well as the predator-prey and host-parasite relationships in temperate and subtropical latitude ecosystems.
- Furthermore, experimental cultures of some species of cephalopods are performed with the aim of optimising culture production systems.
- Conservation and sustainable use of marine biodiversity
- We study the biological diversity and biogeography of cephalopods from habitats all around the world, as well as the influence of fishing activities, organic contaminants and heavy metals on the mortality and reproductive potential of the main species of marine mammals from the north-eastern Atlantic. The purpose is to model the trophic pathways of these contaminants until they reach these marine mammals and to decide the most appropriate measures for their conservation.
- Characterisation of cephalopods breeding and spawning grounds of commercial importance.
- Ecoparasitology of marine organisms
- Ecoparasitology is half way between Ecology and Parasitology. It is based on the same principles as Ecology of free-living organisms, but it shows a greater complexity, taking into account that both elements of the host-parasite interaction are subject to two selective pressures, microenvironment (interaction between both) and macro environment (or pressures from the environment). This research line is especially linked to the resolution of ictiopathology and malacoparasitology case-studies.
- Currently, this group coordinates the European PARASITE Project (KBBE-FP7: 2013-2015), a Consortium composed of 21 partners and 15 countries to address the research needs identified by European Food Safety Authority (EFSA) regarding the risk of seafood-borne parasites.
- At present, this group manages two biobanks of samples and molecules from marine parasites of biotechnological interest for diagnostic, therapeutic and research purposes. Biobank philosophy is to control the samples cession-donation process and to define a laboratory infrastructure that guarantees the quality, order, destination and traceability of these samples and their associated data, which is necessary during its preparation, storage, conservation and transport. These biobanks of parasites have been created in the field of extractive fishing and aquaculture, at the global level. The creation of this new platform to support translational research not only ensures access to a service of samples and biomolecules of high quality standards but it also establishes an industry benchmark for public research and for technological based companies. This infrastructure has been certified with ISO 9001.
