An interesting piece on vertical ocean farming

#1  Postby Calilasseia » May 01, 2017 6:29 pm

Here's an idea that looks like a potential winner ... 3D vertical farming in the ocean.

Grow kelp and other seaweeds to be used as vegetable input into our diet, along with edible molluscs, use small-scale fish traps to supplement the crop with a fish catch (or, better still, integrate a fish farm into the setup) and it becomes possible to produce food efficiently with only a small area footprint.

Furthermore, on a sufficiently large scale, ocean farming of this sort could become a new, and valuable, carbon sink.

There are oyster and mussel farms on the Alabama Gulf coast that do this, and it's generating a lot of interest around Apalachicola. Apalachicola Bay is famous for it's oysters, but the industry is dying because of saltwater intrusion. The Apalachicola river empties into the bay, which reduces it's salinity, but the mega-shithole of Atlanta is sucking up all the water before it makes it to the bay. The thinking is vertical farming of more salt resistant species is an answer. We need to do something, the industry has been almost destroyed. Fuck I hate cities.

Locally it's A pa latch a cola (all short vowels).

Another river that empties into the same bay is the Ochlockonee (o-KLOCK-nee)

We need to work on the demand side. At least global warming has that going for it.

I dunno. The issue is actually pretty complicated. Global fisheries crash will have catastrophic ​effects on civilization for sure. But ocean farmed fish might not alleviate the pressure on those fisheries. The fish we can farm tend to be pelagic rather than benthic and farming Atlantic salmon in the pacific has a bit of a Jurassic Park subtext. The cages rain toxic shit down to be carried away with the.currents which leaves a definable trail of damage. Etc. Freshwater fish farming, hell yes. Tilapia in big tanks? Great idea. But there are some gray areas let's just say.

In addition to the concerns expressed here, there is also the long term worry that escaping farmed fish will introduce genetic material into wild fish populations that will ultimatedly damage the survival of the said wild fish populations, because the farmed fish are not subject to the same natural selection processes as are the wild fish. That's the theory, anyway.

... Also, this issue will not necesarily be slow to take effect, because it concerns only selection not mutation.

Agree! With the increasingly scary prospect of food shortage today, all such solutions need to be explored. I've been reading up on a few environmental issues essays that detail alternative food sources. I am now convinced that we are soon going to switch to different diets to sustain ourselves.

Yes. They do matter but they also need very strict regulations. That side of the story is significantly overlooked

There is no food shortage ....there is a horrid distribution problem.

Aquaculture is already strongly regulated but the choice of what is farmed is problematic as some species cost more fish protein than they provide.
Barramundi is a better fish as they produce from vegetable protein rather than other fish. ( it's also superb taste unlike tilapia and some others )

Bringing back the wild salmon rivers is also a monumental task in progress and some hydro dams are being removed.
In the Snake river ....every single salmon that returns to spawn is caught, tested for genetic diversity to rebuild the wild stock.
Fascinating story.
