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.
Grossly inspired by:

Sounds a little fishy to us .... |

That's just certain to give people the hump. And basically, it's just mean. |
|
|
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. |

// some really rather quite large underwater speakers// |
|
|
Not to mention somewhat fairly immense gigantic unobtainiumalistic thermonuclear-powered power amplifiers. |

Yes, please post a picture! |

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. |
|
|
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. |
|
|
Gotta pay the piper to call the tuna. |
|
|
Presumably the speakers need to have a lot of bass? |
|
|
Every time...every bloody time... |
|

Whelk, what did you expect ? It's always the same, you come over all remorasfull and start whaling, then you go crabby. Here's a squid for a cup of tea, now go and bother some other grouper of people. |
|
|
Is there a fish called an oforfuxake? |
|
|
If there is, no doubt the Japanese will eat it with relish, or possibly soy sauce. |
|
|
I'm pretty sure you'll find they use chopticks. |
|
|
OK, so that's a time measuremet based on grilled lamb ribs, yes ? |
|
|
TOO ... MUCH ... INFORMATION... |
|
|
Does your Mother know you do that ? |
|
|
Come on, people. I know we get some fishy ideas around here, but this is on a whole new laver. |
|
|
I am not going to get sucked in to descending to this level
again. I'm too much of a manta even consider it. |
|
|
For Cod's sake, your sole reason for posting this idea was to elicit fish puns. Do we have to shout ? Are you hard of herring ? Must you carp on about this ? Get down off your perch, don't just flounder around. Mullet over band come back when you're happy. Don't be koi. Not all your ideas are pollocks. |

This is crab! - It'll never work! Give it up and go back to surfing prawn! |

Christopher Moore, in " Fluke ", or " I know why the winged whale sings " postulates a similar premise. |
