Any way that you could make it accept Mysterious Raw Fish from the "O-Sushi-mod
mod?

P.S. Wouldn't mind a "demystrifying recipe" that could turn Mysterious Raw Fish back into Raw Fish. I have inquired with the "O-Sushi-mod" author about this as well as they have a recipe that seems to destroy the fish rather than convert them back.

Edite the data-final-fixes.lua rename the Myterious Raw Fish in osm-raw-fish like this.
You only can catch the fish by hand

fillRecipe.ingredients = {
{type = "fluid", name = "water", amount = 1 },
{type = "item", name = "empty-barrel", amount = 1 },
{type = "item", name = "osm-raw-fish", amount = 1 }
