I've considered starting a business of indoor wasabi farming.

Setting up a new shrimpcoin miner in my basement
Backed by POS (Proof of shrimp)
dude just likes playing with sea monkeys and thought he found the sea monkey money cheat. people won't eat those but like, dogfood.
No that's brine shrimp.
Gotta up your hydroponics game bro! Raise fresh water prawns are bigger and you can grow hydroponic organic pesticide free greens over them which are sustained by the nutrients from the prawn waste.
They call those setups aquaponics. It's a really cool system and one I would love to have as an indoor farming setup some day when I can finance it.
Currently I die a little inside when I do aquarium filter cleaning and water changes. The amount of nutrientns I cannot re-use is saddening. So much good fish poopy going to waste.
Another cost consideration is the food safety licensing and whatnot you would need to have.
So, forgive my ignorance, because I really don't know what I'm talking about, but isn't it possible to use oysters and/or snails to filter and clean your tank in lieu of a mechanical filter? Or does that have a lot of issues I'm unaware of along the way
If you pick up coco coir (an inert medium for hydroponics when plants need a bit more rooting structure) you can dump that sludge right over top to water whatever plant you have growing in it.
If it ends up getting kinda gross, take it outside and hose a bunch of water through it to rinse it, good to continue. But mostly it just causes the coir to break down a bit faster than it otherwise would, due to the bacteria, so this is basically like adding compost continuously.
Doesn’t work for every plant, but does work for a lot of them! I have potatoes in such a setup right now, and it’s pretty swanky.
Nice! I do dump my buckets into some of our garden beds on occassion. I was a little shy about using it after I watered a houseplant and it grew some kind of fumgus on the soil but that cleared up. I'm guessing that might be the kinda gross you mentioned.
I really hope to get some raised beds for food plants this year but already have a greenhouse needing that needs to be built.
I use my used aquarium water for our fruit trees, and they love it.
Thanks for reminding me that we should know if our hearty fig tree made it through winter. We've had hearty hibiscus for several years so I'm optimistic.
Wow! Tell me more!
You can add a third tier to the system: fresh water tilapia. The waste from the tilapia feeds the shrimp and the water from both fertilize the plants. The idea is to replicate natural nutrient cycles. The whole setup can be done outside in warmer climates, or indoors using LED grow lights. I've seen outdoor grow setups done in old in-ground swimming pools.
I was going to say CRAYFISH BOTTOM FEEDERS but in trying to educate myself i learned that they would be competing with the shrimp. so instead of shrimp farm, Crawdad farm! you do one, i'll do the other, we'll be neighbors, we can ride ponies to work, mine will be named Snuffles and yours will be named Clip Clop (Clip Clop loves salt licks so don't let her near the tank) and we can put it right next to the cheesery and cafe that i just decided is part of my fantasy.
I am so down with this fantasy, but I might be too heavy for a pony. I've always wanted a donkey though because I found out they can be friends with dogs. My poodle/sheepdog would love a donkey buddy named Clip Clop.
We could also get you two ponies you could landski
Aquaponics is great, you can start with a small tank, a few 5 gallon buckets for gravity and media filters, a a simple water pump to make the filtered water go up a shelf into a grow bed made from a big bakery container (filled with clay balls), a bell siphon to bring the water back to the fish tank, some pvc pipes for the piping. Grow lights, sump tank, bioreactors, water heater, and pH tester are optional but recommended. Replace the pvc with hdpe or uv treated pp after prototyping.
Start with tilapia which have a wide range of temps and pH they are ok with. But honestly I don't like the flavor of the greens it produces, dirt is the way to go for cabage and lettuce if you care about flavor, unless we are talking about a survival situation. However for things that have their own flavor like herbs, this setup works well.
I feel like ornamental shrimps are probably more lucrative. The fancy black and white ones go for like 30$ each and you can fit a lot of them in an 100 gallon aquarium.
Market is probably smaller, though.
You can sell the rest to the restaurants
okay, so i've posted briefly about this here, but get a biiiiig tank and some 25 cent feeder goldfish. people can't tell the difference between them and koi and honestly, they're pretty. we got to be close enough friends with the sushi chef at the our local place that we had him over for game nights and he wanted to buy our 25 cent feeders when they got like 2 feet long. we couldn't take a hundred bucks for a 25 cent fish named Lunch
