This is so cool! I learned about tilapia when looking into closed-loop hydroponics; apparently they are good at growing in tanks, growing fast, and fertilising the water.
(if you look it up in youtube though you will get tilapia harvesting videos, which are not the nicest)

- markdown 9y ago> closed-loop hydroponics Aquaponics?
- rhaps0dy 9y agoI guess; I didn't realise there was a difference in the terms.
- markdown 9y agoHydroponics and aquaponics are both considered closed-loop (compared to other agricultural methods). Hydroponics involves growing plants. If you're raising fish in addition to crops in your system, with the fish excrement providing the nutrients the crops need, then you're engaged in aquaponics.
- donquichotte 9y agoIt's not really closed-loop though, is it? You still need to buy food to feed the fish (and maybe fish food, which will end up in your vegetables, can be contaminated, e.g. with heavy metals?) Or am I missing something?
- gbuk2013 9y agoThose closed systems involve growing algae which is used to feed the fish.
