What the heck is wild farming? Is it different to organic farming?

Hello, British Redditor here. :) I'm seeing food in supermarkets that's labelled as wild farmed. What the heck does this mean?

The best description I could find seemed indistinguishable from organic farming. Is this a way of saying "organic" without having to pay to be certified organic? I asked Google but Google just kept telling me about wild crafting, which is not the same word.

I'm from London, which isn't exactly a farming hotspot. I didn't know who to ask so I'm here. TIA for any help. :)
