GCFI 69th session

The 69th GCFI annual meeting has been very rich in terms of information related to the Sargassum influx.

- 3 posters have been presented during the poster session on Tuesday, November 8th
- Climate Regimes and Occurrence of Sargassum in the U.S. Gulf Of Mexico,
GUILLERMO SANCHEZ-RUBIO et. al (presented by Donald Johnson, co-author)

Population Genomics of the Sargassum Biome

Taxonomic Guide to Pelagic Sargassum in the Caribbean Sea and North Atlantic

- an informal meeting was held on Wednesday, November 9th with participants including coastal managers as well as researchers and representatives of NGOs and the fisheries sector. Discussion among the participants brought out several needs to cope with the issue. We identified different groups of stakeholders needing specific strategies to address the landings of sargassum in terms of management and communication: Government / Coastal managers, NGOs, Tourism, Fisheries and the public.

- 9 presentations have been given during the Technical session : “Understanding and management of the pelagic Sargassum influx in the Caribbean” hosted by the SPAW-RAC and SPAW Secretariat of UNEP-CEP in collaboration with the Association of Caribbean States, the Centre for Resource Management & Environmental Studies (CERMES - UWI), the Sargasso Sea Commission and UNEP-Global Programme of Action and Global Partnership on Nutrient Management.. The presentations provided the latest scientific information on the origin of the sargassum influx with consideration of oceanographic, climatological, ecophysiological characteristics (links with nutrient increases) as well as the genetic properties of the algal species involved and their associated fauna. There was also a focus on the current status of the forecasting research that highlighted existing data and expertise for setting up short-term predictions, and further described the ongoing efforts and progress towards developing long-term prediction in forecasting future potential landings. The debate has been rich and opened about the understanding of the phenomenon and management recommandations in response to the landings have been presented.

One of the next steps of the on-going collaboration between the SPAW-RAC and SPAW Secretariat, the Centre for Resource Management and Environmental Studies of the University of the West Indies, the Gulf and Caribbean Fisheries Institute, the University of Southern Mississippi, and also the Association of Caribbean States, is to develop specific and short recommendations (several fact sheets and interactive videos). These will be prepared for each group identified according to the specific context of the landing areas (e.g. beach width, beach composition, enclosed bays, turtle nesting areas, wave action, etc.). If you are interested in joining us as a resource person, for the development of these recommmendations please send us an email stating in which area you will be able to help us (Communication, Management, Fisheries, Tourism, NGO, Governmental office, Research, Environmental education).
