Not exactly sure where to put this topic but thought I'd start here...
We have the opportunity to accept several hundred pounds of dead, whole invasive carp weekly. Some of the carp are 30+ pounds...3 foot long, a belly the thickness of an average adult thigh. It could prove to be valuable fertilizer for our garden.
The first drop-off coincided with a barn clean out so we took the bedding...a lot of it, added the fish and now we wait. We don't generate anywhere near enough carbon to use this solution long term... If it even works. Our neighbors aren't super close, to us, but they're great neighbors, but stinking fish wouldn't go well.
Our primary concern besides smell is keeping any solution from attracting rodents. We have no control over when or how much shows up, so any expenses would preferably be minimal.
We don't have any means to easily dig trenches and bury them... The thought of shoveling a trench large enough to bury a 55 gallon barrel worth of fish on a weekly basis exhausts me... And I don't shy away from hard work.
We did this on a small scale a couple years ago with our kitchen blender. The blender hasn't been the same since and any emulsion solution I'm aware of would be capital intensive.
Sealed container rot emulsion
With these parameters, the best idea I've been able to come up with is to get a "rain barrel" type container with locking lid (for smell, rodent proof) and let living things do what naturally occurs...rot. does anyone have experience or thoughts on this? Any inputs required? Maybe some soil micro organisms to simulate rot? Cover with water? Add yeast?? The goal would be a liquid slurry that might need minimal agitation to break up large remains, drain/filter, and apply to garden/pasture via spray or pour into a hoe'd-in trench.
If anyone has any tips, suggestions, new ideas all input is appreciated... Would hate to lose such an opportunity and have it go to a landfill or otherwise.
