Great white Sharks

[Wansworth]

Just watched a documentary by Attenborough about California which talked about the increasing number of young great whilte sharks traveling up the coast and apparently is related to higher. Sea temps.According to the documentry probably they will extend much further north but at present not a danger to humans but could become so……this might have a Bering on the Orcasoff the Iberian peninsular?

Scary thought.
As far as I know, they have already been gps tracked and proven off the west coast of France for certain. A number of reported sightings off the south coast of UK and a couple off the west coast of Scotland too.
I used to work off South Africa often, on ships as a marine engineer. The seawater temps off cape town were usually around 15/16 oC, when I was there and monitoring it at least. Don’t need to tell you that there is famously a huge population of them there. Also won’t need to tell you that the temps around the west coast of Scotland are around the same or occasionally more, with the influence of the Gulf Stream. Makes you think eh.

Big increase in Great White populations in the NE USA due to increase in seal populations IE shark food.

The sharks stay away because of the midgies.

Orcas have been in the Med sice time immemorial. They are mentioned by Pliny 2000 years ago.

Overall I do believe the midges draw more blood than the sharks.

Isn't the Med one of the Great White nurseries? Certainly pups have been caught in Turkey, Sicily and a few Greek islands recently.

There are resident orca in the uk. They don’t bother with the temps, as far as I know

for sure. There is a population off the north coast of the Uk too, as far as I know. I’ve seen them near Shetland

I think I read somewhere that the Scottish Orca haven't had a calf for some time, no one quite sure why by possibly fertility issues caused by pollution IIRC. They'll go locally extinct, if that's the case, which would be a shame.

Does anyone have a link to info on the GPS tagged Great Whites off western France? I couldn't find anything. That would be interesting.

Given how common seals are, I've always wondered why we don't have them (white sharks) off the UK coast. It would often crop up in diving circles if someone saw a large shark in UK waters but GWS never confirmed as far as I know. I once glimpsed a large shark whilst diving the Hebrides, really was a fleeting glimpse so couldn't ID but we decided it was probably a Porbeagle Shark, or maybe a Mako both of which are UK resident or summer visitors. I think it's likely that reported great whites in the UK are misidentified Porbeagles or Makos.

Great Whites have been caught in the Med with a hot spot seeming to be between North Africa and Malta. I think their primary prey is Tuna or other large fish, which is perhaps why they don't come closer inshore and eat tourists!

A very good reason for keeping 3000 miles away.

Won't do you any good unless you're upwind

Killer midges bite yacht mast?

Living where I do, I am very grateful for the SW prevailing wind.

Blimey. We’re cancelling next years Ionian Charter then!

I saw a documentary recently regarding seals on the Angolan( or Namibian?) coast, and Orcas were catching the pups by swimming right onto the shore, then re-launching themselves. Also makes you think!

Hopefully they won’t move to the channel coast! I might have trouble leaving my road on foot

You're gonna need a bigger boat......

I hadn't realised they lived that long.

Not many fish left in British waters so the GWS may stay away, on the other hand, given the amount of seals around Ramsgate, they may just take up residence ?
