Global hackers to solve fishy issue
A HOST of different hackers from around the globe recently battled it out to help solve a problem set by a Pembrokeshirebased scientist.
Between Friday April 2 2 and Sunday (Apr 24), hackers aided in filling crucial gaps in what we currently know about the state of fisheries around the world.
An army of 2,000 coders gathered in 43 different host cities across six continents for the third annual Fishackathon, solving a problem set by the Welsh ecological consultancy Salacia-Marine, WWF, Young’s Seafood and the US-based Billfish Foundation.
The coders were set the task of inventing a technology which would allow fishermen to reliably gather data about fish length and species from images taken by the on-board cameras, which is a crucial element to take into account when assessing the health of global fish stocks.
Dr Andy Woolmer, Pembrokeshire-based Marine Scientist and founder of Salacia- Marine, said: “A fundamental measurement we need is the length of the fish being caught. This gives us an indication of ages and, together with data on how many fish are being taken from the water, we can use it to derive a range of other important statistics which can help us manage fisheries more sustainably.
“At the moment, this data is available for less than half the global catch. Traditionally we’ve relied on measuring fish by hand at sea, which is time-consuming and expensive.
“If the Fishackathon can come up with a solution to our problem, it has the potential to transform our knowledge of fish stocks around the world.”
The challenge was developed in partnership with fishermen as part of the Cardiff-based EU LIFE+ funded Celtic Seas Partnership, a WWFled project aiming to bring people together to create a more sustainable future for our marine environment.
This challenge is one of nine selected by a global panel of experts. The Fishackathon was established by the US State Department to find ways of overcoming the big technical hurdles facing sustainable fishing.
WWF-UK’s Head of Marine Policy Dr Lyndsey Dodds said: “Fish are a critical part of the global marine ecosystem. Millions of people around the world depend on fish for their livelihoods and more than three billion of us rely on seafood as a major source of protein.
“In 2015, our Living Blue Planet report showed that populations of some marine species around the world, including a number of important fish populations, are in decline.
“WWF is working with the fishing industry to help identify solutions to some of the problems faced in achieving sustainable fisheries.
“By putting this problem forward to the Fishackathon with industry partners, we hope the hackers can help us find a solution that’s not just applicable in the UK but across the world.”
The problem which has been put forward to the Fishackathon builds on the previous winning solution ‘Fish-otron’, which showed how it is possible to make quick and accurate length measurements from images collected by the on-board boat cameras.
However, at the moment there is no technology that can distinguish, reliably, between the different species of commercial fish. What is hoped would be created in this year’s Fishackathon is a piece of tech that can both provide this alongside length measurements of fish.
David Parker, Marine Biologist and Head of Corporate Social Responsibility at Young’s Seafood Limited, said: “As the UK’s leading fish and seafood business, we understand that our planet is precious and that we must respect and help to preserve its natural resources.
“Our ‘Fish for Life’ sustainability programme is the way we seek to improve our impact in everything we do and we’re pleased to be supporting the Fishackathon by giving a speech and offering Young’s food to those taking part at the London event.
“This innovative event will help to generate new ideas and solutions for assessing the health of fish stocks, which is vitally important to us as we believe in doing the right thing for people and the planet, now and for generations to come.”
The winning coders from the Fishackathon will be selected by a panel of judges and announced on Wednesday June 8 to coincide with World Oceans Day.
A total of $10,000 will be up for grabs in prizes, and one team’s creation will be further developed independently with an investment from the US Government.

Man charged with attempted murder after Carmarthen park incident
57-year-old due in court following alleged knife and stalking offences
A MAN has been charged with attempted murder following a serious incident in Carmarthen town centre last week.
Dyfed-Powys Police confirmed that James McKenna, aged 57, from Carmarthen, has been charged with attempted murder, possession of a bladed article in a public place, and stalking.
The charges relate to an incident in Carmarthen Park on Thursday (Jan 29), which prompted a significant emergency services response and caused concern among residents.
Police have not yet released full details of the circumstances, but officers were seen in and around the park area for several hours following the incident while enquiries were carried out.
McKenna is due to appear before Llanelli Magistrates Court on Thursday (Feb 5).
The Herald understands the case involves allegations of both violence and targeted behaviour towards an individual, with stalking listed among the charges.
Public concern
Carmarthen Park is a popular and busy public space used daily by families, dog walkers and joggers, and incidents of this severity are rare.
The news has prompted concern locally, particularly as the alleged offences include possession of a knife in a public place.
Residents have previously raised questions about safety in parks and open spaces across west Wales, especially during darker winter evenings.
Court proceedings
At this stage, the charges remain allegations and the case will now proceed through the courts.
Magistrates will decide whether the case is sent to Crown Court due to the seriousness of the attempted murder charge.
Further details are expected to emerge during Thursday’s hearing.
The Herald will be attending court and will provide updates as they become available.

Sex offender jailed after living off grid in Pembrokeshire and refusing to register
Man walked into police station after months avoiding authorities
A CONVICTED sex offender who told police he intended to live “off grid” rather than comply with legal monitoring rules has been jailed after handing himself in at a Pembrokeshire police station.

Christopher Spelman, aged 66, of no fixed address, appeared for sentence at Swansea Crown Court after admitting breaching the notification requirements of the sex offenders register.
The court heard Spelman was released from prison in Dorset on July 4 last year but immediately refused to provide police with an address, despite being legally required to do so within three days.
Instead, he indicated he planned to buy a tent and live outdoors.
Prosecutor Brian Simpson said officers subsequently launched a nationwide search when Spelman failed to make contact with police. Public appeals were issued and his case featured on the television programme Crimewatch.
Detectives believed he had been travelling around the UK using public transport and staying at campsites. He was known to have links to several areas including Merseyside, Manchester, Devon, Cornwall and Hampshire.
His whereabouts remained unknown until January 3 this year, when he walked into Haverfordwest police station and was arrested. It is unclear how long he had been in Pembrokeshire.
Spelman previously served seven years in prison after being convicted in 2014 of 12 counts of sexually assaulting a girl under the age of 14. He was placed on the sex offenders register for life.
The court heard this was not the first time he had failed to comply with the rules. After an earlier release in 2016, he again failed to register his address and avoided police for around five years before being caught.
He has 11 previous convictions for 29 offences.
Defence barrister Andrew Evans described the case as unusual and said his client had long disputed his original conviction and had expressed a wish to live “outside society”.
However, he said Spelman had gradually accepted that he remained subject to court orders and now wanted more stable accommodation and a chance to rebuild his life. The defendant asked the court to impose a custodial sentence so arrangements could be made for his future release.
Judge Geraint Walters noted there were signs Spelman wished to change but warned that any further breaches would result in longer prison terms.
With credit for his guilty plea, Spelman was sentenced to 10 months in prison. He will serve up to half in custody before being released on licence.

Former Wales rugby star admits Christmas Day drink-driving offence
Ex-Ospreys captain was almost twice over limit in Pembroke town centre
Former Wales back row Jonathan Thomas has admitted driving through Pembroke town centre on Christmas Day when he was almost twice over the drink-drive limit.
This week Haverfordwest magistrates heard that Thomas, 43, was stopped by officers as he drove his Mercedes CLA 220 along The Green, Pembroke, at around 5pm on Christmas Day.
“The officers were very concerned at the manner of his driving, as the car was being driven erratically and was swerving to the other side of the road,” said Crown Prosecutor Sian Vaughan.
“When Jonathan Thomas got out of the car, the officers could see that he was having difficulty standing and was unsteady on his feet.”
Subsequent breathalyser tests showed Thomas had 62 mcg of alcohol in his system, the legal limit being 35.
Thomas, who has no previous convictions, pleaded guilty to the drink-drive charge and was represented in court by solicitor Jess Hill.
“He has family in the area and had travelled to spend time with them on Christmas Day,” she told the magistrates. “He’s very remorseful for his actions and hugely regrets his decision that day.”
Jess Hill concluded by saying that Thomas is currently “between jobs and living off his savings”.
Thomas, who gave his address as Main Road, Bredon, was disqualified from driving for a total of 18 months.
“The length of your disqualification reflects the fact that you were more than a little bit over the limit,” commented the presiding magistrates when imposing sentence.
He was fined £120 and ordered to pay £85 costs and a £48 court surcharge.
The former Wales back row left his role as Swansea RFC head coach at the beginning of December 2025 as a result of ongoing health concerns. He was forced to retire from playing in 2015 on medical advice after being diagnosed with epilepsy and is one of the 390 former rugby union players currently taking part in a concussion lawsuit against the sport’s authorities.
“Long-standing issues linked to the head trauma have caused me some concern recently and it has been impossible for me to give the role everything it needs,” he said in a previous interview with the BBC.
His rugby career started out with Pembroke RFC juniors before moving to Swansea RFC, which he captained when he was 19. He then joined the Ospreys where, over a ten-year period, he won four league titles and an Anglo-Welsh Cup. He was the youngest player to captain the Ospreys and, at the time of leaving, was the joint highest appearance holder, together with Andrew Bishop, on 188 appearances.
His international career saw him play for Wales at Under-16, Youth, Under-19, Under-21 and Sevens levels. He made his senior international debut against Australia in 2003, featured at the 2007 Rugby World Cup and was part of two Six Nations Grand Slam-winning sides in 2005 and 2008. Between 2004 and 2011, Thomas was included in every Wales Six Nations squad. In his appearances for Wales, he scored seven tries.
