Water released to help boost fish stocks

Published

on

nrwNATURAL RESOURCES WALES is taking steps to encourage salmon and sewin (sea trout) to reach their spawning grounds and improve stocks. The dry September weather has been a welcome treat for most but for Wales’ fish populations the lack of rain is hindering their annual migration. To combat this, NRW has worked with Dŵr Cymru Welsh Water to release water into the rivers Tywi and Cleddau to encourage adult salmon and sewin to enter the rivers from Carmarthen Bay.

Dave Mee, Fisheries Team Leader for Natural Resources Wales, said: “The River Tywi and its population of salmon and sea trout is worth an estimated £10.2 million to the Welsh economy and the release will benefit anglers as well as boost fish numbers. “The prolonged dry summer has meant that flows in all our rivers are unusually low but it’s hoped the release will encourage migratory fish, especially salmon, to enter the rivers from the sea.” The release will take place over five days, beginning on Monday morning, with water from Llyn Brianne and Llys y Fran reservoirs being released into the rivers.

The release of additional water from the reservoirs will not affect the public water supply and people who use the river have been alerted to take care as the flow will increase to four times its current level. When Llyn Brianne Reservoir was built in the late 1960s a water bank was created to help mitigate against the loss of natural floods and to help fish migrate at critical times of the year. A similar but much smaller release from Llys y Fran has been arranged for the Eastern Cleddau and it will be the first time the fisheries’ water bank has been used to help fish stocks in the Cleddau. Although indications are that sewin numbers have slightly improved this year, salmon returns continue to struggle.

Dave added: “As well as this release of water, anglers too can help us protect and improve these vulnerable stocks by releasing the fish they catch so they can continue on their way to spawn.” Tony Harrington, Dŵr Cymru Welsh Water’s Director of Environment said: “After the driest September in almost 100 years, we are pleased to be working with Natural Resources Wales on this project which will help protect aquatic life in these rivers. “As well as storing water for drinking water purposes, some of our reservoirs also play a vital role in helping to regulate river levels to ensure fish habitats are protected.

This is particularly true after such a dry spell such as this and reflects our commitment to protect the natural environment in our care. “The release of the water will be carefully managed to ensure that the reservoirs continue to meet the drinking water needs of our customers in the surrounding areas.”

Cheesy names for Folly Farm’s five Humboldt Penguin Chicks

Published

on

FOLLY FARM has announced the arrival of five new baby Humboldt penguin chicks—the first penguin chicks to hatch at the zoo since 2021!

Keepers have resumed breeding Humboldt penguins as part of a managed European Breeding Programme for the species, facilitated by their membership with the European Association of Zoos and Aquariums (EAZA). These chicks are the first to arrive at the zoo in three years!

Humboldt penguins are classified as a vulnerable species, facing numerous threats in the wild. Breeding had been on hold at Folly Farm, and the keepers are thrilled to be able to breed again.

The delightful new penguin chicks are growing rapidly and are snug in their nest boxes, cared for by both parents who alternate feeding duties while the other enjoys a swim in the pool. Chicks can double or even triple in weight every couple of days! In a few weeks, they will leave their nests and be taken by experienced keepers to their Penguin Nursery facility, where they will spend a few weeks learning to feed on whole fish and swim in their small ‘baby pool’, before graduating to the main pool with the rest of the colony.

The naming theme for this season is cheese, with the chicks being named Mozzarella, Camembert, Cheddar, Halloumi, and Gorgonzola. Who doesn’t love cheese?

Penguin Keeper and Assistant Zoo Manager Caz Davies shared her excitement: “We’re so excited to have chicks again. Each breeding season, keepers choose a catchy naming theme to easily identify the birds. Penguin chicks can’t be sexed until they’re a bit older and feather samples can be taken, so we’ll just have to wait for a gender reveal for now!”

‘Mozzarella’ was the first to hatch on 30 March to parents, ‘Magnum’ and ‘Feast’, followed by ‘Camembert’ on 2 April, whose parents are ‘Perci’ and ‘Puffy’. ‘Cheddar’ arrived soon after on 5 May to ‘Whippy’ and ‘Pippy’, and ‘Halloumi’ hatched on 10 May to first-time parents ‘Einstein’ and ‘Darwin’. ‘Gorgonzola’ is the youngest chick and hatched on 14 May to ‘Popple’ and ‘Pudding’.

Penguin Coast is currently home to 22 Humboldt and 14 Macaroni penguins. Guests won’t be able to see the newest arrivals quite yet—but keep watching Folly Farm’s website and social platforms for updates!

Anticipation builds for more Northern Lights as solar activity peaks

Published

on

IN the wake of a mesmerising display of the aurora borealis last weekend, experts predict further celestial spectacles are imminent due to heightened solar activity. A substantial sunspot cluster, responsible for recent intense solar flares, is expected to face Earth again in approximately two weeks, potentially sparking more geomagnetic storms and Northern Lights displays.

Scientists at the Met Office, including space weather forecaster Krista Hammond, report that this activity is part of the approaching solar maximum, a peak phase in the Sun’s 11-year cycle marked by increased magnetic upheavals and sunspot production. This cycle, the 25th since systematic observations began in 1755, is proving more vigorous than anticipated.

Last Saturday’s geomagnetic storm, categorised as a G5—the highest alert level by both the Met Office and the US National Oceanic and Atmospheric Administration—was the most severe since 2003. Triggered by multiple coronal mass ejections (CMEs), the storm disrupted high-frequency radio communications globally and posed challenges to various satellite operations.

The aftermath of the storm highlighted our vulnerability to space weather. SpaceX’s Starlink satellites experienced significant strain, leading to voltage spikes, as reported by the European Space Agency (ESA). The added radiation also disturbed GPS signals, impacting everything from aviation—necessitating the reroute of a transatlantic flight—to precision farming, with reported disruptions in GPS-dependent agricultural machinery.

On Earth, the heightened electrical currents tested power grid robustness worldwide. In New Zealand, some circuits were temporarily shut down as a precaution, while the UK’s electricity network operators implemented measures like extra back-up generation to manage potential voltage fluctuations.

This heightened solar activity brings not only stunning natural displays but also underscores the critical importance of preparedness for space weather impacts. The UK government ranks extreme space weather as a significant threat on its national risk register, citing potential severe consequences such as widespread power outages and infrastructure damage.

According to Sean Elvidge, a professor in space environment at the University of Birmingham, the recent storm serves as a reminder of the potentially devastating effects of more powerful storms, like the historical Carrington Event of 1859, which disrupted telegraph systems and caused widespread fires.

As the Sun continues its active phase, the role of advanced forecasting and international cooperation in mitigating space weather effects becomes increasingly crucial. Agencies like NOAA and the Met Office are enhancing their monitoring capabilities, ensuring that critical infrastructure and governments worldwide are forewarned of impending solar storms, thus safeguarding both modern technology and the daily lives dependent on it.

Gething crisis: Tory Leader signals no-confidence motion in First Minister

Published

on

IN a bold assertion that could intensify the political instability in Wales, the Conservative leader in the Senedd, Andrew RT Davies, has indicated that a motion of no confidence against First Minister Vaughan Gething is increasingly likely. This comes in the wake of recent revelations and internal disputes within Welsh Labour that have put Mr. Gething’s leadership under severe scrutiny.

The controversy escalated following the dismissal of Hannah Blythyn, the minister for social partnership, who was accused by Mr. Gething of leaking confidential text messages to the press—an allegation she firmly denies. The leaked texts were reportedly from a pandemic-era group chat, which Mr. Gething admitted to deleting, details of which were first reported by Nation.Cymru.

This incident is part of a broader series of challenges facing Mr. Gething, including scrutiny over the substantial donations made to his leadership campaign. It was disclosed that his campaign had received £250,000, with a notable £200,000 contribution from a company led by a businessman previously convicted of environmental crimes. Mr. Gething announced he would be returning £31,000 to Labour from the campaign funds amidst this controversy.

In crisis: First Minister, Vaughan Gething

Adding to the upheaval, Mr. Davies criticised the First Minister’s leadership on BBC Radio Wales, questioning Mr. Gething’s transparency and ability to govern effectively. He emphasised the urgent need for Mr. Gething to justify his actions, particularly the sacking of Ms. Blythyn, to restore public trust in the government.

On Thursday, in an interview with ITV Wales, Mr. Gething defended his decision, highlighting the importance of trust and confidentiality among ministers and maintaining that his team was aligned on government priorities. He underscored the challenges faced by his administration and the need to focus on issues crucial to the Welsh populace.

Despite the turmoil, any formal motion of no confidence is not expected to be tabled immediately, owing to procedural and logistical considerations. With Labour holding half of the seats in the Senedd, the success of such a motion would hinge on cross-party support or abstentions from within the Labour ranks.

As tensions mount, the political landscape in Cardiff Bay remains fraught with uncertainty, with the potential for significant shifts in governance depending on the developments in the coming weeks.
