This course deals with practical issues of the management of natural resources that have increasing importance in the current marine ecosystems of the Anthropocene: marine biological invasions, as a threat to biodiversity, and the treatment of species in captivity to prevent negative impacts on marine ecosystems.
University of Oviedo
Module 1 (3 ECTS): Management of marine menaces.
Biological invasions: Attributes of invasive species. Recipient communities. Factors that favor invasiveness. Introduction vectors in marine ecosystems: ballast water. Fouling. Aquaculture and accidental introductions. Secondary dispersal. Quarantine and management techniques. Marine invasives in Europe. Management of invasives databases. Socioeconomic aspects of marine invasions. Prevention versus eradication. Social perception of invasives. Risk analysis and cost valuation. Genetics of marine invasions. Applications to early detection, identification of cryptic species, monitoring of exotic populations, inference of origin. Genetic variability of invaders. Coevolution of exotic species and recipient communities.
Module 2 (3 ECTS): Management of populations in captivity.
Principles of aquaculture. Main species for aquaculture in Europe. Main aquaculture procedures. Culture and reproduction. The relationship between aquaculture and conservation. Biological and ecological criteria for the selection of new species. Practices of culture and breeding in aquaculture. Reproduction: manipulation and induction. Impact of alien species. Environmental impact of marine aquaculture. Sustainable aquaculture. Novel techniques for sustainable aquaculture: sustainable water use, feeding systems, residue treatment. Control of new pathologies and genetic diffusion.
Graduate level in sciences. Basic knowledge in genetics is recommended.
Students should be able to apply biological, genetic and ecological knowledge to make decisions about practical aspects of the management of marine resources, such as prevention and/or eradication of marine introductions; the use of new species for aquaculture; sustainable management of aquaculture facilities; the evaluation and prevention of environmental impact of aquaculture.
To use molecular tools for detection, traceability and management of marine species.
To identify biological processes and patterns of importance of managing marine biodiversity and populations in captivity.
To be provided online in the virtual campus of the University of Oviedo. State of the art articles, reports, books.
