I am conducting my research at OGS, within the ECHO group (modelling). My work, which aims at the restoration of the European flat oyster (Ostrea edulis) in the Adriatic Sea, is part of the MER (Marine Ecosystem Restoration) project, in collaboration with ISPRA. Specifically, my contribution focuses on the development of a larval dispersal and connectivity model for the target species.

For this purpose, I am using a three-dimensional Lagrangian model (LTRANS – Zlev), which, by integrating specific hydrodynamic fields, simulating both horizontal and vertical larval movements, and incorporating a larval growth module, is able to predict the potential final positions of the larvae.

These results are expected to play a crucial role in achieving the project’s ultimate goal. Knowing the likely settlement areas will allow us to design targeted interventions, such as placing suitable substrates to promote larval settlement and metamorphosis, or introducing protective measures against bottom trawling in sensitive areas. In addition, it will be possible to develop a complementary model aimed at identifying the most suitable and proximal substrates, in order to assess where, and if, settlement could effectively occur.

An innovative aspect of my research is the attempt to integrate two activities that are often challenging to combine: modelling and fieldwork. In this regard, I took part in a monitoring campaign within the project, where I contributed to and observed several sampling and analysis activities, including the collection and analysis of water and sediment samples, environmental DNA (eDNA) analysis, and seabed monitoring through the use of a ROV.
