jerryd August 16, 2017 12:59 PM The only fish farming viable is vegetarian fish fed on algae, etc clean food or grow them to feed other fish. The slop they feed farmed fish is terrible, wasteful mostly fish wild fish eat and gets far worse from there of anything they can find. Not a chance I'd ever eat Asian farmed fish, shrimp as their feed, conditions are not healthy. But I don't understand we already have the largest, lowest cost to maintain and free fish farms now, the Ocean, rivers, streams, lakes. To make them productive beyond anyone's dreams, is just stop screwing them up!! Tampa Bay and from fresh to salt water everywhere here in Florida, fishing is great because we let it heal and stopped pumping pollution, etc into and to it. Offshore it needs some help like more reserves and allow limited large grouper fishing again as the suckers got too plentiful and eating everything now. watersworm August 16, 2017 01:00 PM Just ask "deep ecologists" about this. I'am sure they'll love it ! Loving It All August 16, 2017 01:09 PM Fron the article: "Areas like North America and Europe, which have the capital and technology to exploit ocean-based aquaculture, didn't come out well because heavy environmental regulations make establishing such farms an arduous and expensive process. Meanwhile, other areas were deemed unsuitable because such regulations were too lax, resulting in coastal pollution." This strongly suggests that the practices being recommended have major negative environmental impact. If there were environmentally benign why would there be a clash with existing environmental regulations? And, it's clear that without a degreee of such regulations, the practices would run harmfully out of control, hence the "resulting coastal pollution." So, how about a discussion of how to farm in an environmentally benign fashion? This is the same challenge we face with terrestrial agriculture, and it's insane not to consider how to live sustainably. The only other choicea are to poison ourselves or our children, or to poison others and their children. Kpar August 16, 2017 01:12 PM Expansion of free enterprise into these areas will cause a bloom in economic activity and allow those poor countries to become food exporters, and consequently, much less poor.The world needs this- we are outstripping the natural oceans' ability to regenerate. Win, win! Douglas Bennett Rogers August 16, 2017 02:50 PM This could be the first cash crop for a pelagic nation. CharlieSeattle August 16, 2017 04:17 PM Ocean Fish Farms? Uhh, sorry but Japan is busy nuking all the worlds oceans now!Japan Declares Crisis As Fukushima Reactor Begins Falling Into Ocean And Radiation Levels Soaryoutube. com/watch?v=-j3Mu3LcqpcPublished on Feb 5, 2017 Unimaginable Disaster: Japan Declares Crisis As Fukushima Reactor Begins Falling Into The Pacific Ocean And Radiation Soars To The Highest Levels Ever Seen.The latest developments at Japan's Fukushima reactor have been described as "unimaginable"and "unprecedented". Officials state that damages at the reactor are "far worse than previously thought". Melted fuel has come in contact with underground water and the melted core appears spread over an "extensive area". .....................Fukushima Is Still Melting Down... youtube. com/watch?v=aRbVHGwkYLE .....................youtube. com/watch?v=psb9nPu2xV8 Radiation levels at the Fukushima reactor have also soared to their highest levels since the 2011 disaster. The radiation levels inside the containment vessel of the number 2 reactor at the crippled Fukushima Daiichi nuclear complex stood at 530 sieverts per hour, the highest since the 2011 disaster, the plant operator said on Thursday. Previously the highest radiation level monitored in the interior of the reactor had been 73 sieverts per hour.The new radiation level, has been described by some experts as “unimaginable,”. These are record high fatal radiation levels, according to the institute.Another truly unsettling revelation about the Fukushima problem came as a boss revealed 600 tons of fuel melted, and they can’t find it. “Uncontrollable fission” is continuing under the site. Grunchy August 16, 2017 05:30 PM There's a practical aspect to deep sea fish farming, namely that the sea gets pretty wild. So how is the farm net to survive? Also how are the fish inside to survive when the sea is crashing around them and they cannot escape? I mention this because the article photo doesn't resemble the sea very often. Bob August 16, 2017 05:35 PM Any time you concentrate live stock, you get disease. Then you need antibiotics. Then to preserve profit, the sick fish must be harvested before they die. The oceans around the poor and unregulated countries are basically full of sewage and chemical pollution. Even the rivers in the U.S. are full of runoff chemicals and more sewage than the public realizes. Most cities release raw sewage every time it rains. The fish will be fed the lowest quality feed and drugs to make them grow faster. Fish farming sounds like a good idea but profit will create an inferior product. Several attempts have been made to harvest plentiful nuisance Asian carp from U.S. rivers for animal feed but so far it has failed. Lake Michigan salmon are full of PCBs other species are contaminated with mercury. icykel August 16, 2017 07:24 PM Wonderful, the future food supply sorted for the new Martian settlements. Nelson Hyde Chick August 17, 2017 01:01 AM Instead of finding ways to feed an ever expanding humanity we should be looking into shrinking mankind. By the time humanity hits nine to ten billion the Earth will just be one huge shithole.
