The 1.5 meter long robotic fish each requires about $30,000 to make. Their purpose is to head out into the open water, take in data about water pollutants, return to a charging station about every 8 hours and while charging, submit data about water quality.
The issues with this first batch of fish is pretty clear - they're way too expensive to be made in numbers big enough to be very helpful; their charge lasts just 8 hours so they aren't able to have a very large range away from their charging stations; they run a pretty good risk of getting a bite taken out of them.
$30,000? Jesus. For half the cost of a single fish I'll rent a paddle boat and troll the underwater sensors myself. I swear, these idiotic scientists think a robot is the solution to every freaking problem. Which leads me to my next question -- how much do you think a robotic fish would fetch on eBay? Wow, really? Grab your tacklebox and meet me by the dinghy!

Thanks to Julian, Brando, mandar3000 and Dustin, who went fishing with Mario, Link, and Mega Man but didn't catch anything but a buzz.
