Fish emulsion and hydrolysate sustainability check

[Toil]

So I looked into my fish hydrolysate made by Neptune's Harvest.


It's menhaden (or bunker), a fish we need to stop catching altogether IMO and ITO of many marine biologists who study the eastern seaboard of the US.

I was wondering if anyone else has looked into their fish fertilizer, and what they found, and if there are alternatives. It's just such handy stuff.
