An alternative to CRAB MEAL for my soil

Guy, so I’ve just about managed to get all I need to build my TLO but can’t get crab meal from anywhere inside the EU??? I’ve sat and spent 3hrs looking for this stuff last night but can not find it.
Are there any alternatives that I could use instead please??

Insect frass should do the trick. Crab meal is used for the chitin in it, which insect frass should be able to cover.
Also, can you not order it off Amazon?

Awesome, I’ve just found a product called “ecothrive” which says it’s beetle frass… That’s the stuff I need is it???
