New fish farming method provides virtually guilt-free seafood
Recirculating Marine Aquaculture filters and recycles water and uses methane from fish waste to offset energy use.

This is a very good idea. We need to preserve the natural order in the oceans and seas in order to ensure the livelihood of a variety of species necessary to sustain essential ecosystems. http://cbt20.wordpress.com/2010/04/12/biotechnology-and-fishy-personalit...
Feed the fish corn! They are much more efficient at converting grain to protein than cattle of pigs, and the methane fis produce can be trapped, and used as fuel, fuel we sorely need! The "Poop" will serve as a n excellent fertilizer and top-soil builder too! The "Offal" from the harvest can be added to the fertilizer, or all, poop, offal, can be bio-gassed to run cars, or for cooking gas as in India! America is catching up in many ways to the third world efficiencies, and will soon overcome.... More
Feed Corn to Fish?! Corn is not a fish's natural food and corn is also an extremely eco-UNfriendly crop, most of it is GMO, and it consumes water and soil fertility like nobody's business. Corn and soymeal are the reason that eating meat in this country is so unsustainable (try grass-fed on rangeland!). Feeding fish bugs (like maybe the pests from organic farms), like one poster mentioned, is a much better idea.
I was thrilled to read this article. I confess we barely eat fish any more due to our concerns about over-fishing and unhealthy farming. Where can we purchase fish raised in this much greener environment?
Yes, fish feel pain. Yes, it sucks to be eaten. But you know what? That is nature. Omnivores and carnivores are part of the natural balance. If it's not us, a larger fish or bird or mammal will eat that fish. I can't stand seeing a baby bird get plucked off by a hawk, but it happens. And I'm not going to be angry and righteous at the hawk about it.
This is not to say that the way we are *harvesting* these animals is at all OK. We are too smart for our own good; we found more.... More
I appreciate efforts to go "green." However, if you are taking the life of another being when you don't have to, there's nothing ethical or guilt-free about that. Animals (including fish) feel pain and distress, and they certainly don't want to be eaten.
A vegan diet that also strives to be organic, local, seasonal, etc., is much closer to guilt-free than eating animals will ever be.
"Wanting" is a human emotion. Fish don't "want" anything. You're anthropomorphizing them.
Actually, animals do have wants, one of the most significant being pain avoidance. If animals (incl humans) didn't have this feature, we'd be doing many activities that could result in injury and possibly death...and that's no way to safeguard the survival of the the species, now is it?
All animals -- incl. fish -- feel pain. Sorry, but I don't consider a fish that experienced oxygen deprivation or a hook in its mouth to be "guilt free"
Since we can grow insects very cheaply and in mass amounts, and they are something a carnivorous animal can live on, why don't we start feeding them to the fish? Y'know, like bug meal? Except for the ick factor, we humans could add them to our own diet, and some societies still consider them food and delicacies.
from your article: "Green fish, as good as it gets”, says Yonathon Zohar, director of the Center of Marine Biotechnology at UMBI. “Clean, environmentally friendly, sushi-quality fish, delivered to the restaurant a few hours after harvesting." gives me great hope...thank god that innovation is still alive in our world...it gives me optimism for the green future
We're so destructive towards the earth, we have to think smart on every topic...even with this, will there be any fish left in 30 years? in 10 years? now?
i'm definitely curious to read more about this, especially the ways in which the fish waste are managed. i'd also love to see what teras grescoe thinks about this new method!
