This was prompted by [2-fries] scheme for cymatic aggregation of plastic waste in the sea.
Cymatics (as 2-fries and I, at least, know) involves transforming sound into physical patterns. A common method is the formation of Chladni patterns: sand sprinkled on a drumskin or other resonant surface will collect itself into ridges and nodes which correspond to the stationary points on the vibrating surface.
Now, there is no reason why this would not apply to fish in an ocean in three dimensions as easily as it applies to sand on a drumskin in two dimensions (actually, there is a very good reason, but I am going to ignore it completely. I can produce my artistic licence upon request.)
So, simply take any convenient fishing fleet, some really rather quite large underwater speakers, and any of the currently available supercomputers. A little tinkering and tweaking and - calypso mori! - 3-D Chladni patterns of fish! A single large trawler can then simply travel along the cymatic lines, scooping up the dense collection of the sea's bounty.
Plankton too could be concentrated into economically harvestable patterns by this approach, as could dolphins, whales or other tasty morsels.-- MaxwellBuchanan, Jan 03 2011 Grossly inspired by: Gyrebage_20collectionwhich would work as well as this would.

That's just certain to give people the hump. And basically, it's just mean.-- 8th of 7, Jan 03 2011 Turn the amp up to 11 and stun the fish (like the snapping shrimp).
Actually, notwith standing waves, this idea is a bit skewed. As I'm sure you know, [MB], we'd need a enclosed volume of water or some very coordinated array of speakers (hence super computer?) that would simultaneously need to constantly sync, never sink, all while expertly using sinc.-- Jinbish, Jan 03 2011 // some really rather quite large underwater speakers//
Not to mention somewhat fairly immense gigantic unobtainiumalistic thermonuclear-powered power amplifiers.
//I can produce my artistic licence upon request// Yes, please post a picture!-- csea, Jan 03 2011 We hake to have to tell you this, but [Jinbish] is right - where you plaice the speakers will be critical. We would prefer not to rays the issue, but it's not an aspect of the problem you can just skate over.
If, rather than a net, you made a grid out of long pieces of wood recycled from ships, you could deal with the "scoop" problem by means of a Spars Array technique.-- 8th of 7, Jan 03 2011 This might work too well, especially since fish are generally self-propelled and might be induced into patterns without requiring the sound to be THAT loud.-- cowtamer, Jan 03 2011 Gotta pay the piper to call the tuna.-- 2 fries shy of a happy meal, Jan 03 2011 Presumably the speakers need to have a lot of bass?-- pocmloc, Jan 03 2011 Every time...every bloody time...-- MaxwellBuchanan, Jan 03 2011 Whelk, what did you expect ?
