Dr Sara Da Silva Pires Marques Barrento

I am a highly motivated professional in marine science with 9 years’ experience. I have worked mainly with seaweeds – kelps, and marine invertebrates - crustaceans and bivalves. I have worked in different Universities in collaboration with companies from Europe, New Zealand and Chile in a range of subjects: aquaculture, biotechnology, biochemistry, and physiology. 

I am presently the Module coordinator of:
BIO 003 Laboratory Skills
BIO 004 Molecular Biology and Biochemistry

I am co-supervising a master and a PhD student:

Student name: Camilla Norris
Lead supervisor: John Griffin
Institution: Swansea University
Funding: KESS

Title: Establishing the knowledge base for sustainable seaweed cultivation

  • BIO335 Fisheries and aquaculture

    This module provides an introduction to the operation and management of commercial fisheries with particular relevance to the current over-exploitation and decline of most commercial fish stocks, and the potential for changing this situation by using aquaculture

I have been involved in 5 Research Projects funded by the European FP6, FP7  and Horizon2020 funding schemes, and 4 projects funded by Research Councils in Portugal and the UK. I have collaborated with 11 research institutions, 24 companies and 9 associations from 11 countries globally. My research mainly focuses on food safety and security, and the blue economy. I have authored 18 scientific publications.

Presently I am interested on the development of sustainable production systems for marine macroalgae and animals. I am mostly interested in integrated multi-trophic aquaculture (IMTA). The basic concept of IMTA is the farming of several species at different trophic levels, that is species that occupy different positions in a food chain. This allows one species’ uneaten feed and wastes, nutrients and by-products to be recaptured and converted into fertilizer, feed and energy for the other crops (Chopin, 2012). As an example we can combine, the cultivation of fed species (finfish or shrimp) with inorganic extractive species (seaweeds or aquatic plants) and organic extractive species (oysters, mussels and other invertebrates). You can learn more about IMTA on my TedEd lesson here (http://ed.ted.com/on/H7rUYhKF)
