How To Make Fish Fertilizer

Remember that old story of the natives teaching the Pilgrims to bury
fish beneath their corn plants? It works. Thatโ€™s why โ€œfish emulsionโ€ or
โ€œfish fertilizerโ€ is still sold as a common organic fertilizer. Plants
love it โ€“ and you can make it yourself. This is a good thing, because
fish emulsion is really expensive.

More on making fish emulsion and LOTS of other great composting ideas!

As I posted previously, my friends Rick and Mart came over a few weeks ago for a major yard work day. Both of these guys are pretty hard-core plant geek/survivalist/homesteader types.

When they arrived, Rick said, โ€œHeyโ€ฆ I brought you a little gift from the Caribbean market.โ€ He then proceeded to haul two buckets of nice fresh fish guts and parts from the back of his truck.

I was thrilled. What thoughtful friends I have!

Once I had this bountyโ€ฆ it was time to make it into something amazing for my plants.

If you have access to fish waste, you can do the same thing I do. Itโ€™s easy and it smells incredible. Hereโ€™s how Iโ€™m doing it.

Step 1: Get A Big Barrel

After this particular project, youโ€™re not going to want to use this barrel for anything else, so choose wisely. I got a great used 55-gallon drum with a top from the local feed store:

You want a lid for this thing to make sure animals stay out and that
none of the fish turn into undead zombie fish and escape in the night.
Theyโ€™ll come in your windows and stuff, trashing your house and eating
your brains. Donโ€™t let that happen.

Step 2: Throw In The Guts!

If life give you rotten fish… make fish fertilizer!
Isnโ€™t that an amazing picture? I think that should be the cover of a punk album. Or maybe something by Aphex Twin.
You can almost smell the ocean. I threw in crab parts, too, since theyโ€™re loaded with calcium and other nutrients. I donโ€™t know how well theyโ€™ll break down in the final scheme of things, but I imagine theyโ€™ll go eventually.

Step 3: Add Some Carbon!

We all know about the whole C:N part of composting, right? That is, for nitrogenous material, it helps to add some carbon so the microorganisms get plenty to snack on as they break down a pile. Iโ€™m doing the same thing with my fish fertilizer. In this case, I used shredded moringa tree trunks.

Youโ€™d never know there was a hellish slop of yucky piscine waste beneath that, would you? Looks pretty innocuous, if I do say so myself. You could probably use sawdust, mulch chips, shredded paper or straw in this mixโ€ฆ the idea is just to give a little more balance to your fertilizer. Weโ€™re anaerobic composting, hereโ€ฆ it may be nasty wharf-scented sludge, but itโ€™s still compost.
