Growing Veggies with Fish Waste
Following up last fridays post on farmed salmon I couldn't resist this story from New York Times reporter, Michael Tortorello about a growing trend in the do-it-yourself gardening realm called "Aquaponics".
Here's how it works in a nutshell. You build a fish tank and fill it with anything from tilapia to trout. You feed the fish. The fish naturally have to make waste. Fish waste and and water is pumped from the fish tank to what's called a "flood tank" - much like the holding tank on the back of a toilet. The nutrient rich water from the flood tank is fed to a small garden or grow bed of pea gravel and whatever type of edibles you'd like to eat. The plants use the water and nutrient-rich fish waste to grow. The oxygenated and cleaned water is then drained back to the fish tank as clean water, starting the process all over again. Check out this slide show on the process. Or you can watch a video here.
Not only can you grow veggies, but say you want to have fresh fish every once and a while all you'd have to do is reach into the fish tank and whack a trout for dinner.
The people participating in this style of gardening is growing and setups can be the size of a dinner table to an entire greenhouse that's several hundred square feet. The author writes about, "a day when aquaponics set-ups could be built into new apartment complexes and be fed by municipal waste and geothermal power".
Does gardening with goldfish seem like it's worth the hassle or just a passing fad? - TR

I'd love to try this. I plan on starting a garden in the spring and I've always wanted a big aquarium with crappie and walleye. Maybe I'll look into it.
hmm.. this is where the chicken litter goes, but typically after composting for a couple of seasons. I wouldn't worry so much about the cleanliness of this approach, but i bet you smell it.
I've been casually studying aquaponics for a few years and I think it's a great concept. The main reason I haven't started a project is that I already have more "hobbies" (hunting, fishing, shooting, scuba diving...) than time. Unfortunatly, this may have to wait for retirement when I'll have enough time to do this right.
interesting
"new apartment complexes and be fed by municipal waste"

So they're going to grow urban gardens fertilized by apartment sewage? Am I the only one just a little bothered by that?
...
On the other hand, I like the idea of watering the salad and the main course (trout/bass/etc) at the same time. Pretty inventive.
Neighbors have used fish tank water for years to water their house plants and herb garden. Automating this, filtering the water at the same time, is brilliant - simulating mother nature.
Uhhhh, Tim....tell me again what this has to do with fly-fishing, or sport fishing resources, or anything else besides gardening?
(oh, wait - I get it! You grow WORMS in the compost, right?)
Woodstock - if they do this right we could have man-made trout streams running along alleys or rooftops in big cities.
woodstock,
well, nothing really. Just thought it and interesting segue from my post on farmed salmon from friday.
I apologize if you didn't find it entertaining or "fly fishy" enough. I'm sure Deeter will get back into it tomorrow.
Just throwing up something a little different...
Holy fish paste, Batman!
That's some stick to your ribs grub!
I like the topic. It mixes things up and can be thought provoking. I'm not keen to the idea of eating veggies grown by fish poop but the whole idea of conserving, recycling and clean water should be right up a fishermans pole.
Why not? It makes sense.
Native Americans used fish (leftovers from cleaning them) as crop fertilizer and passed it on to white settlers.
We use manure from quail, bats, chickens, cattle and it works very well.
Good article btw
Nice concept. My wife and I would like to start a garden this spring, but probably just a very small conventional one.
We have a major greenhouse here where i live that uses hydroponics to grow its veggies, if this "aquaponics" is anything like the hydroponics we have here, they can have it, the hydroponic tomatos could be used for baseballs they are so hard.
Back in the 80's I hitchhiked to Cape Cod to visit the New Alchemy Institute, a sort of hippie sustainable living and technology farm that pioneered a lot of sustainability concepts. They were doing the Tilapia- Tomatoes aquaponic thing back then in a great big geodesic dome. The place was life changing for me, with the wind turbines and the domes and the organic fields.
So the tilapia waste fertilizing tomatos and other veggies works really really good. I'm not doing any aquaponics yet myself, but maybe sometime in the future. Tilapia taste good!

excuse double posting...my bad.
I was just thinking today about erecting a greenhouse over the septic tank. It would then be heated from below.
This article gets me thinking about more options.
Thanks!
The greatest energy resource in America goes down the crapper. The potential for biogas fuels generated from waste is immense, but people are conditioned to shy away from anything involving poo. I have a half finished biogas generating composter, (and a gas fired hot water heater to use the gas) but I can't finish it because the powers that be want an engineer to vet my design, but relevant engineers are only interested in Big projects and have it seems little interest in supporting small farm digesters for independent biogas production. They are all about retrofitting municiple systems, which is good, but they have been no help to me and my efforts at sustainability. I think my only hope is to find some sharp engineering student who needs a semester project.
What kind of green energy should we choose? All of em. I was excited to read about the "Bloom Box" a new lower cost fuel cell,(they say 2 of 'em could power your house). A "Bloom Box" coupled to a biogas digester would allow you to fuel the fuel cell yourself and get fertilizer from the garden as a handy byproduct.
