You can totally intergrate this mod: https://mods.factorio.com/mod/microplasticsfromfish

Also make it output light oil, because fish oil obviously

Oh good idea, I'll ask / add credits to the modmaker.

Thanks for both the suggestion as reminding me to add some fish (-using) recipes I haven't gotten around to adding yet :D

Speaking of fish, I hope there are some new recipes for bioflux involving fish or other organic material of sorts.

Completely unrelated and sorry for necroing this thread but I was looking for that too and found the biochemistry mod which adds localized nutrient methods to all spage planets

Galore also has nutrients sources for all planets through the "Nutrients from ammonium sulfate" recipe. (ammonia + sulfur = nutrients)

(This suggestion has been added as the bioflux from fish recipe. The plastic from fish recipe didn't quite make it unfortunately.
