#Seafood - Donegal's oyster industry has been hit by an import ban in Hong Kong over an outbreak of food poisoning.

According to The Irish Times, food safety investigators in the Chinese territory were notified by Irish authorities two weeks ago that the presence of norovirus was confirmed at a raw oyster processing plant in the north-eastern county that services the crucial Asian market.

Hong Kong subsequently banned the import of raw oysters from Donegal "for the sake of prudence". More HERE.

#Shellfish - The Food Safety Authority of Ireland (FSAI) is holding a series of Shellfish Regional Information Meetings around the coast in April and May.

The informal events, held in association with the Sea-Fisheries Protection Authority (SFPA), the Marine Institute and Bord Iascaigh Mhara (BIM), aim to provide an opportunity for all those involved in the shellfish industry to learn more about the role of the Shellfish Safety Monitoring Programme and how it assists industry to ensure that live bivalve molluscs placed on the market meet the highest standards of food safety.

This series of events will focus on microbiological classification of shellfish production areas but will also cover topics such as biotoxin and phytoplankton monitoring, phytoplankton sampling and viruses. 

The first of these meetings takes place on 15 April at the SFPA office in Clonakilty, Co Cork, followed by 16 April at the Brehon Hotel in Killarney, Co Kerry.

On 27 April, the meeting moves to the Clann Ri Hotel in Letterkenny, Co Donegal, followed on 28 April at the Marine Institute in Oranmore, Co Galway.

The final meeting in the series will be held on 6 May at the FSAI office on Lower Abbey Street in Dublin city centre.

Registration for the events in Donegal, Galway, Cork and Dublin is from 1pm with a light lunch served. These sessions will run from 1:30pm to 4:30pm. In Kerry, registration is from 9:30am with tea/coffee served. The sessions will run from 10am to 1pm, when a light lunch will be served.

#Mussels - "Major concerns" abound over an endangered species of freshwater mussel after a Connemara roadway project given the go-ahead by planners before its design was finalised.

According to The Irish Times, locals expected the road project to be an upgrade of the existing route between Oughterard and Maam Cross, but only found out later that a wholly new road would be built through their land via compulsory purchase orders.

Besides splitting a number of farms in Glengowna near Oughterard, the final scheme will impact on the catchment of the Owenriff river, one of Europe's oldest trout hatcheries and host to one of the world's most important populations of the freshwater pearl mussel Margaritifera margaritifera.

And according to an independent ecologist, the presence of the latter means planning permission cannot be legally granted in the way it has been decided.

#Fishing - The unregulated use of pesticides by fish farms poses a significant threat to both the shellfish industry and marine wildlife, according to new research findings.

The Irish Examiner reports on the study by the Norwegian Institute for Water Research, which confirms that pesticides used to kill sea lice infestations in aquaculture schemes often exceed environmental quality standards, or EQS.

Researchers studies samples from fish farms in Norway, which has no EQS system, and compared them to thresholds in the UK.

The study has been welcomed by lobby group Save Bantry Bay, whose secretary Alect O'Donovan claimed the value of shellfish to the local economy was more than €640,000 in 2009.

"It is ludicrous to put this at risk by adding more salmon farms and greater pesticide emissions that have the potential to wipe out stocks," he added.

Management of Ireland's shellfish fisheries and wildlife in general will be up for discussion at this year's Buckland Lecture in UCD next Wednesday evening (29 October), as Derek Evans writes in The Irish Times.

Malcolm Windsor, formerly of the North Atlantic Salmon Conservation Organisation, will be joined by Frank Convery, Ken Whelan and a panel of experts on the night to debate these important issues.

#MarineScience - The Marine Institute has headed a major international project demonstrating the latest advances in shellfish safety. 

Results of this four-year project - presented on Tuesday 10 September at the ASTOX-II Project workshop in the Oranmore HQ of the Marine Institute – were described as very significant for the shellfish industry, and for the institute's key position in the field of marine biotoxin science.

According to researchers, new discoveries made during the project regarding the biological source, chemistry and toxicology of a naturally occurring marine biotoxin Azaspiracid will lead to a better understanding and regulation of the problem. 

This toxin is regulated under EU law and can accumulate in shellfish resulting in closures of shellfish production areas in order to prevent human illness. 

Irish scientists have worked on understanding the nature and origin of the toxin since it was first discovered on the west coast of Ireland in the mid 1990s.

An international group of over 40 world-leading scientists in the field of biotoxin science who attended the workshop described several practical tools that have been developed for the analysis of this toxin and its micro algal source. 

The group also described several new phytoplankton species responsible for producing the toxins, developed new molecular probes and other assays for monitoring the problem, and for the first time produced details of how the toxin affects consumers during and following digestion. 

These answers are essential in setting appropriate shellfish safety standards to ensure that only the highest quality Irish shellfish reach the market, said the Marine Institute.

Another major output of the project was the purification of several Azaspiracid variants directly from Irish shellfish and micro algae for use as certified reference materials. These ultra-pure extracts are essential for analytical techniques and are now distributed to monitoring and research labs all over the world.

“The success of this project is very important for food safety in Ireland and internationally but also for the Irish shellfish industry,” said project manager Jane Kilcoyne of the Marine Institute. “When a bay is closed for shellfish production because of a harmful algal bloom it can cause severe economic hardship for producers in that area. 

"We hope the practical tools developed through this project for example new rapid test methods will help to minimise the impact of these harmful toxins on shellfish producers by providing better prediction and monitoring systems.”

The ASTOX-II project team of Irish, Northern Irish, French, Norwegian, American, Canadian and German scientists worked together on biological, chemical and toxicological aspects of the compound. Since the project began it has generated many publications – including three PhD studies, 29 peer-reviewed papers, three book chapters and 44 presentations at national and international conferences - and others are anticipated after its completion in November 2013. 

These publications stimulate global interest in Azaspiracid research, disseminate new knowledge and reinforce Ireland’s position as a leading performer in marine toxins research. This knowledge continues to enable the development of national and international policy, which supports the development of Ireland’s seafood sector.

Speaking after the event, Marine Institute CEO Peter Heffernan congratulated the scientific team. “This project has brought together a unique team of Irish and international scientists who are among the world leaders in their field of ocean environment biotoxin analyses and draw from the experience of leading marine and food safety organisations in the world whose combined efforts have significantly advanced scientific knowledge in this field,” he said.

The project is carried out under the Sea Change strategy with the support of the Marine Institute and the Marine Research Sub-programme of the National Development Plan 2007–2013, co-financed under the European Regional Development Fund.

The workshop - which followed on from the 10th annual Shellfish Safety Science workshop in Galway earlier this year - continued yesterday (11 September) with a seminar hosted by Agilent Technologies focusing on monitoring of environmental pollutants and toxins using an advanced analytical technique used by the Marine Institute called mass spectrometry.

#Fishing - "Absolutely hammered" is how a Carlingford Lough oyster farmer describes the state of his business after £350,000 (€404,000) worth of his stock was destroyed by a virus in the recent heatwave.

And as the Belfast Telegraph reports, Darren Cunningham now fears financial ruin after at least 80% of his juvenile oysters were wiped out by the ostreid herpes virus, which kills the shellfish when the water temperature rises above 16 degrees.

Unfortunately for Cunningham and fellow oysterman Harold Henning, who fears a total loss of his young oysters, Stormont has no compensation scheme in place for lost stocks in Northern Ireland.

#MarineWildlife - The Guardian reports that fishing is expected to be banned near Rockall after the recent discovery of a rare ocean floor gas vent and new species of shellfish.

The 'cold seep' methane vent found by Scotland-based marine scientists last year is only the third of its kind to be found in this region of the Atlantic Ocean - and apparently has a 'chemosynthetic' relationship with two species of deep-water clam, and the polychaete worms they contain, that are new to science.

Also found was a frilled shark, described as a 'living fossil' for existing as a species for at least 90 million years. Such sharks are seldom seen north of the tropics.

In the wake of these findings, the International Convention on the Exploration of the Seas has recommended a ban on fishing activity at the site and its surrounds.

Rockall - which adventurer Nick Hancock is attempting to occupy for a world record attempt - is a tiny rocky islet north-east of Donegal, almost halfway between Ireland and Iceland in the North Atlantic. It has long been the subject of territorial dispute, with Ireland, the UK, Iceland and Denmark all staking a claim.

The 10th Shellfish Safety Workshop at the Marine Institute was attended by 140 participants including shellfish producers, processors, scientists and industry regulators to hear the latest advances in shellfish safety, including the discovery of an organism that causes harmful AZP toxins in shellfish as well as the use of satellite imagery and models to provide early warnings to fish farmers on harmful algal blooms and shellfish toxicity.

The workshop hosted by the Marine Institute, the Food Safety Authority of Ireland and the Sea Fisheries Protection Authority provided an opportunity to exchange information on the latest progress and research into the cause and control of shellfish toxicity and microbiological contamination of various shellfish products harvested and farmed around our coast.

Mr Richie Flynn of the Irish Shellfish Association said the huge effort and advances that have been made in understanding the nature of these issues are fundamental to the development of the industry. He went on to say "these successful biotoxin and microbiological monitoring programmes that we spent many years developing are now carried out very efficiently, and with the full support of the industry, but we must continue to invest in the most advanced analytical technologies and take advantage of advances in new smart communications in order to provide the best available advice to industry."

Dr Peter Heffernan, CEO Marine Institute said "Ireland has among the highest standards in shellfish safety worldwide because of the strict monitoring and control programmes in place here. Our scientists have led the way in the move to chemical testing for biotoxins and the development of molecular testing methods for shellfish viruses in recent years and this is now the standard across Europe."

Among the research presented at the workshop was the discovery of the organism that causes Azaspiracid, a group of naturally occurring marine toxins that can contaminate mussels. The shellfish industry was affected by this particularly in 2005 and 2012 with significant closures of shellfish production areas. The ASTOX project, which is nearing completion, was presented by Jane Kilcoyne, Conor Duffy and Rafael Salas, who gave updated information on the toxicology of the Azaspiracid group of toxins, the discovery of the causative organism responsible for Azaspiracid shellfish poisoning and how this toxin behaves in the human digestive system and studies on how it affects various tissues.

A new EU project using advanced satellite imagery, mathematical modelling and real time monitoring to provide short term predictions was demonstrated by Caroline Cusack, showing how this multidisciplinary approach may provide useful information on biotoxin outbreaks for shellfish producers.

Trends in shellfish toxins and toxic phytoplankton over the last four years were presented by Dave Clarke and Tara Chamberlain who both identified the extended occurrence of Azaspiracid in shellfish and red tides of the fish killing micro-algae "Karenia mikimotoi" of 2012 as being some of the worst we have seen.

Other research presented included a talk on shellfish hatchery technology by Iarfhlaith Connellan from Cartron Point Shellfish hatchery on Galway Bay on the production of triploid oysters to meet the demands of the Irish industry for oyster seed. Teresa Morrissey, Marine Institute presented the findings of a study to assess the presence and impact of oyster disease which caused oyster mortalities in several areas in recent years.

Bill Dore, John Flannery and Paulina Rajko-Nenow from the Marine Institute discussed the monitoring and detection of high levels of Norovirus contamination which is likely to be legislated for in shellfish in the future.

Dr. Georgina McDermott and Karen Creed from the EPA described measures introduced to reduce pressures and risks on the quality of shellfish, such as designated shellfish growing areas and pollution reduction programmes, and presented results showing certain areas are already improving in terms of eutrophication.

Conference organiser, Joe Silke from the Marine Institute, welcomed the strong attendance at the workshop. "Interest in these monitoring programmes and research activities from members of the industry is vital to ensure that the scientists and regulators are aware of relevant current and emerging issues". He said that the efforts made in controlling outbreaks, and research into understanding and forecasting them can only be successful in a clean and unpolluted environment, and recognised the huge efforts being made by the EPA in reducing and monitoring pollution. He thanked the other agencies including SFPA, FSAI and BIM in working together with the Marine Institute and the Irish Shellfish Association as a superb example of inter agency cooperation to deliver a set of programmes that are effective and efficient in reducing any risks associated with placing shellfish on the market.

#MarineScience - The 10th Shellfish Safety Science workshop will take place at the Marine Institute in Galway on Thursday 18 April 2013.

This one-day event is an opportunity for anyone working in the area of shellfish safety, including regulators, scientists as well as industry, to meet and exchange information on the latest advances in the field.

Irish regulatory agencies will provide updates on recent shellfish biotoxin, toxin-producing algae, harmful algal blooms and shellfish microbiology.

There will be presentations from research projects that are nearing completion on the toxicology and causative organism responsible for Azaspiracid shellfish poisoning which caused extensive economic hardship in 2012 and 2013.

A new EU project using advanced satellite imagery, mathematical modelling and real-time monitoring to provide short-term predictions will be demonstrated, showing how this multidisciplinary approach may provide useful information on biotoxin outbreaks for shellfish producers.  

On the microbiological side, presentations on shellfish contamination from Norovirus and how the Shellfish Waters Directive aims to monitor and improve environmental conditions for shellfish cultivation will be given.   

Further information on these and other aspects of the workshop are available on the Marine Institute website at www.marine.ie. Attendance is free but registration is required by emailing [email protected]

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
