I’ve seen someone collecting lionfish, basically using a litter picker and a bag.

Aye, this is the problem with a lot of invasive edibles. Too few people are interested in foraging and usually you can only eat so much foraged stuff.

If everyone went out with tubs, bags and baskets on their days off and did a bit of foraging to make their diets a bit more varied and healthy then we might be able to make a dent in things like Himalayan Balsam and American Signal Crayfish. Realistically though we’d just have to limit foraging of easier to identify and prepare plants and fungi from easier to access areas.

They do destroy biodiversity but at least they are pretty and won’t fuck you up like Giant Hogweed.

It’s difficult to eat your way through an invasive species. Himalayan Balsam is also edible but it’s thriving in the UK.

In fact edibility is often the reason these things are so invasive, it’s why American Signal crayfish are over in the UK.

Near rivers it has to contend with Himalayan Balsam, and the bees love that stuff too.

Fun fact: If you’ve said “Fuck you whale”, you don’t need to say “fuck you dolphin” as all dolphins are whales anyway. It would be like saying “Fuck you, Great apes (Hominidae) and fuck you human”

But you can say it if you want, it’s just superfluous, but many of life’s pleasures are.
