BIM and Dutch Shellfish Importers - Shellfish Associated Species Inventory (SASI) Surveys
Surveys in key aquaculture bays and non-aquaculture bays around Ireland to contribute to the baseline species register and ongoing monitoring of marine alien invasive species
2018
2022
Guidance to support industry and Government challenges and policy advice as appropriate e.g., Marine Strategy Framework Directive (MSFD) Descriptor 2 (Non-indigenous species) reporting where this project is the only marine invasive species data set for Ireland. Contributions to and oversight of Risk Assessments for aquaculture activities. Support is provided to aquaculture businesses to complete these for a number of scenarios: to support DAFM decision making for certain shellfish movements; to support certification requirements or help achieve management system targets; and to guide responsible business practices.
Areas are surveyed every three years. However, an areas may be visited for mussel culture one year and oyster culture anothers. Different species are typical of different environments. Wider surveys have been conducted including marina surveys and ephemeral mussel seed beds in advance of annual fishery opening.
Island of Ireland
Species identified based on expert examination of morphology and/or DNA analysis. If, for some reason the ID was not certain but the specimens concerned do look in their morphology like the species specified, the term cf (con forma) was added to the identification. In more recent years DNA-analyses have been used as a standard for verifying Ceramium and Ulva species identifications. Older seaweed records were usually identified / verified based on morphology by Dr. Herre Stegenga.
