Thank you guys for the input.
The idea of making fish emulsion first was to have it alredy more broken down and therefore less smelly and easier to mix with the sawdust.
No Bears here just dogs that need to be fenced off.... And flies ( i once dumped 25Litres of fish guts into an underground wood compost and had an invasion of flies bevore I could quickly cover everything up with sand. Incredible! I didn't know where they all came from in just a minute.
I found an interesting article on this topic

Now I switched my thinking from "making sawdust compost with the help of fish" to "composting fish guts with the help of sawdust" (same same but different)
Creating less, but more fertile compost in an enclosed system like a turning barrel or two well closed compost boxes ( so I can shovel it from A to B)
Always covering the Pile with a layer of smell blocking material like ready compost, earth, sawdust or biochar (got a lot of it).
I will purchase the humanure book for shure as we will have to build compost toilets for our new home in the near future.
Thanks once more.
