Giant Free-Roving Robotic Cages Could Be the Healthy Future of Fish Farming


With over 70 percent of the world's natural fisheries taxed beyond the point of replenishment, the demand for farmed fish will only rise in the coming years. Unfortunately, the cramped conditions and shallow locations of most existing fish farms result in low yields and sickly, parasite-ridden fish.

That's where Cliff Goudey, director of the Massachusetts Institute of Technology's Offshore Aquaculture Engineering Center, comes in. He has attached robotic motors to a giant fish cage, allowing it to travel around the sea, rather than stay tethered in shallow water.

The art and practice of abbreviation

Texting slang is, according to one report, more an art than a crutch for the semi-literate. The study found more of a correlation between reading ability and "sound-based textisms," such as "wiv" for "with," than with acronyms like "lol." (No word on who pronounces "with" so that it sounds like "wiv," though.)

The technology behind dissolving sutures finds its way into the tackle box

Even the fishermen are going green. Any angler worth his bait has lost a few lines to the bottom of the fishing pond. And, chances are the line he lost is still lying there with those of his ancestors, damaging coral and killing fish. Traditional nylon lines can take up to 600 years to disappear, but with Bioline, a new "biofilament" line developed by alumni of the med-tech industry, that time can be cut to just five years. That's fishing technology even the fish will embrace.
