Composting fish scraps
I can get all the fish scrap I can use and am wondering how and whether I dare compost it. I'd use a bin made of pallets with another pallet for the top, and could line the inside with plywood if that's appropriate.
The fish scrap comes in 5 gal buckets (~30 lbs), and I'm planning to layer it with sawdust, jointer shavings or wood chips. I've read fish scrap(heads, racks, skins and guts) has a ~6:1 C:N ratio. so I'd add 4 times the wood chips by weight.
So It would seem I should layer the carbon with (bucket at a time) fish scrap (keeping fish away from bin walls), proceed until I get to the top of the pallet bin, wet it all down, cover with a pallet, and hope for the best. Would I want to turn this pile?
I don't have to worry about animals getting at the stuff, but am very concerned about odors. A few years back, I tried a ~60 lb chunk of shark meat in a similar bin, and the putrid odor brought over the health department.
So, what's the best way to do this, given the goal is to compost a maximum amount of fish scrap but not have an offensive odor.
Thanks in advance.
