General information

The growing demand for a sustainable use of aquatic resources has stimulated research interest in untangling the functional relationships between aquatic organisms, including interactions at the basis of food webs. Knowledge of these (trophic) interactions is a prerequisite to understand and to protect the carrying capacity of biological ecosystems. A good characterisation of organisms (plants, animals) is essential to understand the interactions among them. Biochemical profiling allows to screen these interactions at different levels of organisation, from cell to ecosystem. By focusing on specific molecules, so-called biomarkers, we can trace their pathways. Within EMBRC, we screen for pigments, nutrients, stable isotopes and fatty acids.

During this one-day, hands-on course, we will focus on the use of fatty acids as trophic markers. The course aims to provide advanced knowledge on the use of fatty acids as tracers in food web. Gas chromatography (GC-MS, GC-MS/FID with PTV injector) for fatty acid profiling and GC-IRMS for compound-specific stable isotope analyses (CSIA of fatty acids) will be introduced as up-to-date techniques. Next to theory, the analysis, interpretation, reporting and application of fatty acid profiles will be included in the training.

In the morning session, we will tackle the theoretical aspects, while in the afternoon session, we will have a hands-on introduction in the lab.

Application domains: aquaculture (e.g. quality of feeds and endproduct), compound discovery, energy profiling of living material, energy transfer efficiency, stress ecology (functional changes), …
