Western Ecology Tour: Notes from the Field – Pembrokeshire

Published

on

Scubaverse blogger, Donovan Lewis, is currently on the Western Ecology Tour. The aim of the expedition is to travel to the northern reaches of Scotland, along the West Coast to the Llŷn Peninsula in North Wales, and finally onto Pembrokeshire, diving the best the west has to offer. The expedition is looking to live life in a minimalist way, camping and cooking out in the open air.

The teams aim is not just to dive sites, but to tackle conservation issues and shed light on projects up and down the UK, they have three projects which the trip will be focusing on. These projects include the Shark & Skate Citizen Science Scotland, Project Seagrass, and Neptune’s Army of Rubbish Cleaners (NARC). The team will be accompanied with a Biologist or expert that works on each of the 3 projects to aid and guide the team, but also help shed extra light on the critical conservation work being carried out.


Here are Donovan’s notes from the third and final leg of the trip:

Hello once more the final field report from expedition WET, as the expedition reach es its final leg its amazing to see how much we’ve done as a team. In our final leg we we’re in Pembrokeshire where we were covering NARC (Neptune’s Army of Rubbish Cleaners) with Lloyd Jones.

Our first dive was at Hobbs Point at Pembroke Dock. This dive was a sad one, NARC had been called to the area due to a report of several oil drums and other rubbish that had been thrown in the water. We were able to lift four oil drums, nets, a scooter, and much more. There was also a huge amount of fishing gear tangling around the kelp and seabed and even when we were in the water there were anglers on the wall above the dive site.

The next dive lead by Lloyd was at Martins Haven a mere five-minute drive from where we were staying at West Hook Campsite, this site is part of the Skomer Marine Nature Reserve. Here we saw lobster, mating Spider Crabs, a Pink Sea Fan and Moon Jellyfish.

The Final Dive which was also led by Lloyd as he was determined to find us huge amounts of catsharks was at Stackpole Quay on the South Pembrokeshire Coast, This site was a shallow dive at no more 7.5 metres but the dive was full of life with once again loads of mating Spider Crabs, lobster, Pollock, Sand Eel and huge amounts of catsharks.

As the expedition was ending, we found out there were some spaces on the Saturday and Sunday on Celtic Deeps Puffin and Seal snorkel Trips and some of us booked on to go out with them. Let’s just say that day was incredible, but you’ll have to wait for the images in the full trip report.

Creature Feature: Porbeagle

Published

on

In this series, the Shark Trust will be sharing amazing facts about different species of sharks and what you can do to help protect them.

This time we’re showcasing the robust Porbeagle, one of the only known sharks that may love to play..

Shaped like a rugby ball, this muscular stocky shark is incredibly hydrodynamic and built for endurance. Dark grey-blue in colour with a white belly, they have a pointed snout and large black eyes.

Porbeagle’s belong to an elite group of sharks known as the mackerel sharks. These include some of the most powerful and agile sharks in the world, such as the White Shark and Shortfin Mako. This group are endothermic, so can keep themselves nice and warm, due to a remarkable adaptation known as a rete mirabile. This makes them more efficient hunters and able to tolerate colder waters.

Porbeagle’s look a lot like White Sharks, so are often mistaken for them. As they’re found in UK waters, this has led to many false reports of White Sharks in the UK. But Porbeagle’s are around half the size. Although still a large shark, the biggest Porbeagle on record is 3.6m. While the largest White Shark is 6m.

Found worldwide in cold-temperate waters, Porbeagle’s are strong swimmers. Travelling thousands of miles in search of food and to give birth. One individual, tagged in Irish waters, journeyed over 2,000 miles to Newfoundland in Canada. A known mating ground for Porbeagle’s.

Porbeagle’s may live on their own, or in small groups made up of similar sized or same sex individuals. With males and females coming together usually in September-November to mate. Yet in some places this can take place in January.

These sharks reproduce slowly, so are extremely vulnerable to destructive fishing. Females take 12-16 years to reach sexual maturity, males 6-10 years. After 8-9 months, females will give birth to litters of just 1-5 pups, which are relatively large at 60-80cm long.

Two distinct populations exist – the north Atlantic and south Pacific. Individuals from these areas don’t seem to mix, resulting in key differences. North Atlantic Porbeagle’s get a lot bigger, and don’t tend to live as long as those in the south Pacific.

During the day Porbeagles tend to spend their time in deeper waters, rising to the surface at night. They’re opportunistic feeders, mostly eating small fish – such as mackerel, whiting and herring – as well as octopus, squid and cuttlefish.

Highly inquisitive, Porbeagles have been seen chasing each other, rolling at the surface, and even pushing around floating objects and kelp. Could they be playing? Currently there are no scientific studies to back this up. But what an interesting study that would be…!

  • SCIENTIFIC NAME: Lamna nasus
  • FAMILY: Mackerel Sharks (Lamnidae)
  • MAXIMUM SIZE: 3.6m
  • DIET: Small fish & squid
  • DISTRIBUTION: Wide-ranging in temperate waters (except North Pacific).
  • HABITAT: Coastal and oceanic waters from 0-1,800m deep. Prefers temperatures below 18°C but can tolerate -1–23°C.
  • CONSERVATION STATUS: Vulnerable
