Concombre de mer flambé

Matt Slater, a sea cucumber specialist at Newcastle University, claims that these disgusting little invertebrates could be the answer to the layers of uneaten food and fish poo that collect under salmon farms.  Despite its lack of any aesthetic appeal, the sea cucumber has a voracious appetite and will suck up all the detritus like a Hoover.  Once properly fattened, the cucumber can then be collected and sold to gourmet restaurants for a tidy profit.

It's a brilliant idea.  Where it falls down is that the sea cucumber tastes as disgusting as it looks.  This tends to produce what is known as consumer resistance.  Maybe they'll claim it's high in anti-oxidants or something.
