Diving with British Marine Life: The Grey Triggerfish

Published

Part 2 of a new series by blogger Georgie Bull…

Before starting University last September, I dove Chesil Cove in the hope that I could get a glimpse of a triggerfish on the Royal Adelaide wreck. Grey triggerfish (Balistes capriscus) are seasonal visitors to our waters and are known to congregate on the wreck at a similar time each year. They are often fished off or battered by storms fairly rapidly, so sightings are temporally confined too.

 For anyone unfamiliar with Chesil, large pebble ridges create a wonderful pre and post dive work out for any diver keen enough to get in. Jon Bunker (Instagram: @jon_bunker) my Dorset dive buddy did a fantastic job of locating the wreck, and we had a very pleasant dive overall. Jon has invited me along on lots of his diving antics, and he’s the main reason I have so many photos to share.

On the dive we saw the likes of jewel anemones, congers, and a wonderful variety of wrasse. Without a trigger in sight, a couple of tompot blennies fighting one another became the main highlight. After the dive we spoke to a recreational angler on the beach, who mentioned he’d caught (and returned) a triggerfish while we were in the water. We were so close to a sighting!

Once I’d recovered from the pebble ridges and put my kit away, I accepted that I’d have to wait until next year.

Fast forward to a few weeks time, and the University of Plymouth’s Scuba Society were running their first shore club dive at Firestone Bay. I joined in, hoping to see a few different tunicates or echinoderms that I may not see so often in Lyme Bay. Instead, I was greeted with a large and relatively healthy triggerfish sat on the substrate. It turns out, I didn’t need to scale pebble ridges or use Jon’s impressive navigation skills to have an encounter with this species!

Profile

Triggerfish have defensive spines on their dorsal which are used to avoid predation, but also wedge themselves into crevices outside of harms way. Like their namesake suggests, the erection of their largest spine is triggered by the depression of a smaller spine closer to their head. Triggerfish are also known for aggressive behaviour, as they are particularly territorial over their nests.

Grey triggerfish are a Southern European species, and are valued by anglers both commercially and recreationally. This value has resulted in them being categorised as ‘vulnerable’ by IUCN. They are also the only triggerfish encountered in UK waters, with the other 39 species of triggerfish found typically in warmer waters.

Literature

In recent years, it’s been reported that grey triggerfish are becoming increasingly common in the UK. We have plenty of evidence to suggest that our oceans are warming, and we know from previous instances that migratory pelagic fish like the grey triggerfish are capable of shifting their distribution in response to environmental change.

In 1930, a grey triggerfish was recorded in St Malo, France; by the 1990s, they were being described as common in Jersey. In southern parts of the UK grey triggerfish sightings were unheard of too, up until the early 2000s. They are now regarded as common in some areas (like Chesil) at certain times of the year. It would be interesting to see this shift quantified more and understand if the increased catch rates may also be influenced by changing fishing methods and intensity.

Ho Ho Ho! Vobster Quay’s recording-breaking charity Santa diving event returns on Sunday 15th December 2024 for another round of festive fundraising frivolities. Run in aid of the Royal National Lifeboat Institution (RNLI) and Help For Heroes, this ever-popular annual fundraising event aims to raise sack-loads of cash for these two very deserving charities.

Divers of all levels are invited to grab their Santa outfits – and as much festive cheer as they can muster – and head down to Vobster Quay near Mells, Somerset for a mass sponsored Santa dive in aid of charity. In previous years, the event has attracted divers from the far corners of the UK to join in the festive merriment for a final festive dive before the Christmas and New Year break. Back in 2015, the event smashed the world record for the most Santa divers with 188 divers taking to the waters donning their festive finery – a record that remains unbeaten to this day!

Vobster Santas isn’t just about setting records – it’s also about raising some serious cash for charity. Vobster Quay encourages all divers to get into the spirit of the season to raise much-needed funds for two very deserving charities – the Royal National Lifeboat Institution (RNLI) and Help For Heroes.

Through individual sponsorship and online donations, divers can invite their friends, family and work colleagues to sponsor them to plunge into the balmy waters of Vobster Quay dressed in full festive finery. Since the very first Santa dive in 2007, the event has raised over £52,000 for charity. “It’s been over 17 years since the very first charity Santa dive took place at Vobster Quay and every year the event just keeps getting bigger and better” enthused Vobster Quay owner, Amy Stanton.

“Vobster Santas is a great way for divers to say a massive thank you to the both the RNLI and Help For Heroes – two very deserving charities close to our hearts. We’re immensely proud of all that Vobster Santas has achieved and hope that even more divers will join this year’s event on Sunday 15th December. I’m confident that we can make Vobster Santas 2024 the biggest yet!”.
