Found: White albacore tuna

I looked at our big Tesco as well and it wasn't there either. Maybe you could email Princes and ask who stocks it in your area.

Trolls catch fish now?     Do they mean trawl?

My husband has just informed me that trolling is a legitimate term, something to do with deep sea fishing using long lines off the back of a boat. He says he has even done it! But no, he cannot post about it himself being a mere male.

Excellent idea. I've just done it! 

I just got this reply back from them:

Good Morning.
 
I can confirm that this product has now been discontinued.
 
Kind regards
