Objectives: The European aquaculture sector supports several North Atlantic coastal communities. The effects of harmful algal blooms (HABs) and microbial pathogens can have a massive impact on this sector. HABs negatively affect shellfish and finfish aquaculture operations through the rapid accumulation of biotoxins in farmed shellfish consumed by humans, and by killing entire stocks of farmed fish due to toxins, physical damage and deoxygenation. The estimated economic impact of HABs in EU waters may be as high as €919 million per year. Prevention of natural HABs is not possible but reliable early warnings may facilitate effective mitigation measures to safeguard public health and private business operations.
The main objective of Project PRIMROSE is to provide a reliable standard, automated system for reporting and forecasting HABs and microbial events that impact aquaculture operations in European coastal waters. We will build on existing HAB early warning systems developed by our previous successful forecasting system during its predecessor, Project ASIMUTH (reported in a special edition of Harmful Algae, 2016). New features of PRIMROSE will include; an expanded system for new fish- and shellfish-producing areas; improved HAB forecasts with greater resolution; a wider suite of parameters; an evaluation of the potential for mitigation; new index based risk assessments; and a valuable information service for policy makers, risk regulators, food safety authorities and the aquaculture sector, from Shetland to Canary Islands. The new forecast will include microbial risk (eg. E. coli, Norovirus, Vibrio) and environmental/ climate impacts, in addition to improved HAB predictions.
PRIMROSE will benefit from improved spatial resolution, utilising new generation Sentinel data products for the main aquaculture production areas in France, Ireland, Portugal, Spain and the UK. Improved ASIMUTH-developed methodologies for producing HABs forecasts will result from operational oceanographic forecasts, downscaled regional hydrodynamic models, novel satellite data, phytoplankton/ biotoxin monitoring data and expert evaluation. PRIMROSE will upgrade the current HAB forecast service to the regional scale; providing mesoscale trans-national HAB and microbial risk information, risk assessments and knowledge exchange with the international user community. We intend to maintain close involvement/co-development with industry partners throughout the project to ensure maximum impact of the project outputs.
New information from the Marine Strategy and Water Framework Directive monitoring programs; from a new generation of sensors aboard the Sentinel suite of satellites, and sensors collecting underway data aboard ferries, will also be utilised for the alert system. The aquaculture sector relies on sufficient early warning of harmful events, so that effective mitigation measures can be utilised. PRIMROSE will both develop a trans-national short- to medium-term risk forecast, and a long-term assessment of climate impact on HABs and pathogens.
The main objective of PRIMROSE is to provide a reliable standard, automated system for reporting and forecasting HABs and microbial events that impact aquaculture operations in European coastal (AA) waters.

PROJECT TITLE: Assessment of Risk of Benthic Life Stages of Toxic Dinoflagellates to the Seafood Sectors of New Zealand and France

Harmful algae blooms (HABs) negatively impact both New Zealand and French seafood sectors, with risks to both seafood exports and the health of recreational fishers. Many toxic dinoflagellate species develop blooms and have complex life cycles with a resting stage or cyst. Little is known about the direct uptake of dinoflagellate cysts into the food chain or whether it poses a health risk to seafood consumers. This two-year project will enable New Zealand experts to establish a collaborative relationship with French scientists at Ifremer and MARBEC who are experts in HAB cysts. The specific aim of this project is to identify benthic life stages of three high priority toxic dinoflagellate groups, namely, Alexandrium, Azadinium and Vulcanodinium. Cysts will be isolated from sediments around New Zealand and France. Cyst morphology, molecular genetic composition and toxicity will be determined. By identifying and establishing the abundance of benthic cysts beds in both France and New Zealand, predictions of blooms can be made and their likely risk to consumers assessed.
* A workshop (included picture above) on morphological and molecular identification techniques of toxic HAB species, led by Drs Mertens and Smith, was held in New Zealand (12-14 February 2018) to assess both morphological and novel molecular methods for cyst identification. It also provided training for those involved with monitoring programmes internationally (both for micro-algae and invasive species).
* A follow-up workshop led by Drs Smith and Mertens, to coincide with ICHA 2018 in Nantes (France; 21-26 October 2018) will ensure the transfer of expertise and uptake of methods internationallythe transfer of expertise and uptake of methods internationally.
