Surveillance order for aggressive dolphins

Published

on

SEVEN DOLPHINS participated in ‘porpicide’ in Cardigan Bay this weekend when they aggressively attacked a young harbour porpoise.

The dolphins involved have now been photographed and are under observation due to their behaviour.

Cardigan Bay Marine Wildlife Centre’s Marine Team participated in a four hour dolphin survey this weekend as part of The Wildlife Trust’s Dolphin Survey Boat Trips.

However, part way through their survey they witnessed seven Bottlenose dolphins acting aggressively towards a young harbour porpoise. The marine team were amazed to witness the dolphins acting aggressively in that manner and proceeded to observe and document the event.

Sarah Perry, Wildlife Trust Living Seas Science Officer, said: “For decades we have known that Bottlenose dolphins attack harbour porpoises, an act known as ‘porpicide’, a behaviour that has been documented around the world. However, the reasons for these attacks remains poorly understood. Various theories have been proposed including prey competition, objectorientated play, practising infanticide and heightened aggression in male Bottlenose dolphins. Interestingly, this isn’t the first time we have observed this behaviour in the Cardigan Bay Bottlenose dolphins. In 2014, we observed this behaviour first-hand on four separate occasions”.

Cardigan Bay Marine Team photographed the dolphins involved prior to the latest encounter and are now continuing to document and observe their behaviour. At least two of the dolphins involved were males, two were females and there were also two young dolphins in the group – including one dolphin that had faint foetal folds visible, which suggests it was less than a year old.

Sarah Perry continued to say: “Although slightly distressing, observing aggressive behaviour such as this is fascinating to both members of the public and researchers alike. Most days I am left in awe of the dolphin’s power and stealth and hunting abilities. Their behaviours and social systems are complex and encounters with these animals never fail to amaze me. There is no doubt that the Bottlenose dolphins of Cardigan Bay are an inspiration to everyone that is lucky enough to catch a glimpse of them as they go about their daily lives, myself included.”

Encounters such as this demonstrate that we still have a lot to learn about these enigmatic creatures, showing that it is vitally important that we all make an effort to conserve our seas and the marine environment we live in for future generations to enjoy, be inspired and learn from such events.

New Quay RNLI lifeboat crew trains with lifeguards

Published

on

NEW QUAY lifeboat station hosted a special training evening with the lifeboat crew and Ceredigion’s RNLI lifeguards last week.

Pete Yates, one of New Quay RNLI’s inshore lifeboat helms, worked closely with Ceredigion lifeguard supervisor, Tirion Dowsett, to plan scenarios for the teams to practice working together in casualty care situations.

A large scale scenario included four casualties to be dealt with by the inshore lifeboat crew and two lifeguard teams on a nearby beach, whilst a third lifeguard team and lifeboat crew members dealt with a separate scenario at the lifeboat station.

Pete said: “It was a great evening of training. We had 9 lifeguards and 13 lifeboat crew in attendance.

“The main scenario included casualties suffering from hypothermia and propeller injuries. A second scenario involved a mechanic suffering head injuries in the forepeak of the all-weather lifeboat and requiring extraction on a stretcher.

“On completion of these scenarios we all gathered back at the station where one of our senior crew members sprung a great act at being a diabetic having a hypo, and being suitably angry and aggressive.”

Roger Couch, New Quay RNLI’s Lifeboat Operations Manager, added: “It was great for our lifeboat crew members to work with the lifeguards as it builds a deeper understanding of each other’s roles and encourages teamwork between us. This is of great benefit when dealing with real life casualty care situations.”

Coastguard rescues dog stuck on cliffs

Published

LAST TUESDAY (Aug 27), New Quay RNLI’s inshore D-class lifeboat, Audrey LJ, was tasked by Milford Haven Coastguard to assist the Coastguard with a dog stuck on the cliffs near New Quay.

The volunteer crew launched the inshore lifeboat at 1.50pm with four crew members on board and made their way south down the coast.

Brett Stones, New Quay RNLI’s helm said: “We located the dog on the cliffs by Castell Bach, near Cwmtydu. We stood by while the Coastguard team caught the animal. The dog was unharmed and safe with the Coastguard so we were stood down.

“However, while returning to station we were then tasked to a small vessel with engine failure. We towed the stricken boat with three people on board back to New Quay. We rehoused the inshore lifeboat and it was ready for service by 2.40pm.”

New maintenance Lorries cut carbon emissions

Published

on

The Ground Maintenance Team has purchased three new lorries to support ground maintenance services in Ceredigion.

The new lorries will move Ceredigion County Council’s Ground Maintenance Service’s equipment to and from the grounds that they look after. The lorries will also take cut grass away for composting. This provides the most efficient way of maintaining the areas that the team is responsible for.

Councillor Dafydd Edwards is the Cabinet member responsible for Highways and Environmental Services together with Housing. He said: “The new vehicles replace ones which had provided excellent service for almost 20 years. They are fitted with Euro 6 engines which are considerably more efficient and better for the environment.”

The Grounds Maintenance Team is also incrementally introducing electric-powered mowers, blowers, hedge cutters and strimmers into its fleet. This equipment is better for the environment, is easier to use and causes less noise and vibration.

The new lorries support Ceredigion County Council’s commitment to be a net-zero carbon council by 2030.
