So-called "ghost" fishing nets are awful things. Lost or forgotten during commercial fishing operations, they can drift in the ocean for years, indiscriminately catching marine life as they do. A newly-invented tag, however, may help keep that from happening.

According to the University of Exeter, an estimated 400,000 diving seabirds die annually by getting caught in gill nets intended to catch fish. A new study indicates that the majority of those deaths could be avoided, however, if the nets were to be equipped with inexpensive green LEDs.

Longline fisheries may catch a lot of fish, but they also catch seabirds such as albatross. Several years ago, a group of conservationists began work on a product designed to keep the birds from getting caught. It's known as the Hookpod, and a recent study has concluded that it really works.

For this year's CES, Beijing drone-builder PowerVision has taken the wraps off a submersible drone that uses sonar to detect fish, blue light to lure them in and a 4K camera to stream all the action back to the boat.

If you don't recognize a fish you catch, how do you know if you can keep it? With a quick scan of your catch, a new app called FishVerify can identify a species, bring up information on its habitat and edibility, and using the phone's GPS, tell you about its size and bag limits in that area.

When fish are processed in trawlers at sea, the animals' heads, guts and skeletons all just go overboard. It's a lot of waste, so Norway's SINTEF research group has developed a system that puts everything but the bones to use.
