Whooshh Innovations' "fish gun" shoots salmon over obstacles small and tall

By - August 21, 2014 2 Pictures
If you live in an area where salmon spawn, then summer treats you to a free nature drama as the fish battle against currents, fight through rapids, struggle up tiny streams, and leap up waterfalls to return to the calm pools where they were born. Unfortunately, however intrepid the odd salmon is, they weren't built to take on a 300-ft tall hydroelectric dam. That's why Whooshh Innovations has developed a system that sucks the fish up through a plastic tube and shoots them over obstacles low and tall like so many piscatorial projectiles. Read More

Sharks help scientists and themselves, by wearing cameras and swallowing sensors

By - February 28, 2014 2 Pictures
Perhaps you've seen footage from National Geographic's "Crittercam," an underwater video camera that has been attached to animals such as sharks and whales. Well, scientists from the University of Hawaiʻi at Mānoa and the University of Tokyo have gone one better. Not only have they been putting cameras on sharks to see what they get up to, but they've also been slipping them ingestible sensors, to monitor their dietary habits. The data that they've gathered could help protect shark populations, and the overall health of the ocean. Read More

Tiny fish-tracking "jellyroll" batteries should help protect salmon

By - February 19, 2014 4 Pictures
In order to better understand and protect wild stocks of salmon, it's necessary to track their whereabouts using implanted acoustic tags. Needless to say, the longer that those tags are able to transmit a signal, the greater the amount of data that can be gathered. Scientists at Washington state's Pacific Northwest National Laboratory (PNNL) are helping make that happen, by developing batteries that have both a smaller size and higher energy density than conventional fish tag batteries.

Cod inspire potentially life-saving cold storage tech for human blood

By - February 4, 2014 1 Picture
How is it possible that cold-blooded fish such as cod can live in Arctic waters without just freezing solid? As it turns out, they've got proteins in their bloodstream that act as a sort of antifreeze. British scientists have now copied the fashion in which those proteins work, to create a process by which donated human blood could be frozen for storage, then quickly made available for transfusion.

Something fishy about new robotic filleting machine

By - January 28, 2014 2 Pictures
Manual filleting of fish can be a time-consuming task. Due to higher salaries in Nordic countries, processing of fish caught there is often carried out in places like Asia, Eastern Europe and Russia where labor costs are lower, before the fish is returned to Scandinavia for sale. The APRICOT (Automated Pinbone Removal In Cod and WhiTefish) project set out in January, 2012 to find an automated solution that would keep fish processing local and it has now developed a machine that achieves just that.

Rolls Royce to design ship that carries fish as passengers

By - December 8, 2013 1 Picture
Building a ship to carry fish as passengers may seem like a phenomenal case of missing the point, but Rolls-Royce has signed a £5.8 million (US$9.5 million) contact to design and equip one that does just that. The live fish carrier will be built by Turkey's Tersan shipyard for the Faroese salmon farming company Bakkafrost as a way to carry fish from their pens to the processing plant. Read More

Mmm, glow-in-the-dark jellyfish ice cream

Late last month, as a definitely unique way of celebrating Hallowe'en, Bristol-based specialty ice cream-maker Charlie Harry Francis unveiled what is probably the world's first-ever glow-in-the-dark ice cream. His secret ingredient? Jellyfish protein. Read More

Aqualibrium uses fish to grow plants, and plants to grow fish

By - October 25, 2013 3 Pictures
Home aquaponics kits, which combine fish and plants in a symbiotic relationship, are becoming more and more popular. One of them, the Fishy Farm, is a fairly large setup. The Home Aquaponics Kit, on the other hand, is pretty small, while the ECO-Cycle is designed to sit on top of an existing aquarium. The latest arrival on the scene, the Aqualibrium Garden, manages to carve out yet another niche for itself. Read More

Jellyfish-shredding robots dispatched to clean Korea's coast

By - October 8, 2013 17 Pictures
Over the past few years, jellyfish populations along South Korea's coastline have risen to the point where they are adversely affecting the fish populations and marine industries in the area, costing the country over 3 billion won (about US$2.8 million) each year. A team led by Associate Professor Hyun Myung of the Korea Advanced Institute of Science and Technology however may have a solution with the JEROS (Jellyfish Elimination RObotic Swarm), a series of autonomous robots that work together to track down jellyfish in the ocean and grind them into a fine pulp.
