Resum:

Alfacs and Fangar Bay in the Ebro Delta, NW Mediterranean are the major sites in Catalonia for
shellfish cultivation. These bays are subject to occasional closures in shellfish harvesting due to the
presence of phycotoxins. Fish kills have also been associated with harmful algal blooms. The
comparison of phytoplankton dynamics in both bays offers the opportunity to reveal differences in
bloom patterns of species known to be harmful for the ecosystem and aquaculture activities. Field
research is underway under the GEOHAB framework within the Core Research Project on HABs in
Fjords and Coastal Embayments. The overall objective of this study is to improve our understanding
of HAB biogeographical patterns, and key elements driving bloom dynamics in time and space within
these semi-constrained embayments. Via the comparative approach we aim to improve the prediction
for monitoring purposes, with a focus on Karlodinium spp. associated with massive kills of
aquaculture species. This objective is addressed by incorporating long-term time series of
phytoplankton identification and enumeration with the first results of recent field work in both bays.
The latter includes the application of optical sensors, to yield a complementary view with enhanced
spatial and temporal resolution of bloom phenomena. |
