Lake Como, in Northern Italy
Sometimes, the collective knowledge of generations of locals is just as valuable as a network of high-tech sensors. That’s what scientists studying the fluid dynamics of Lake Como in the Italian Alps found, when they began to interview fishermen.
The team from the University of Western Australia had been studying the complex currents and temperature gradations in the Y-shaped lake for some time, using a system of floating sensors. Alongside them were the approximately 30 local fisherman who go out each night to string out their giant gill nets, as much as 2,300 feet long and 27 feet high. In the morning, the fishermen retrieve the nets and any fish—mostly shad and whitefish—that have swum into them overnight. Read More
In the Eastern Mediterranean, the pufferfish has arrived. And nobody’s too happy about it. The fish, also known as the silverstripe blaasop or Lagocephalus sceleratus, was first confirmed in Turkey in 2003 and has been spreading throughout the area. The problem with this unassuming fellow is that it contains tetrodotoxin, a neurotoxin that can be deadly to humans and for which there is no known antidote. Consumption of the fish has killed at least 7 people in Lebanon in the past few years, according to The Daily Star, and likely affected many more. A 2008 study found that 13 Israeli patients who ate the blaasop had to receive emergency medical attention at the hospital, where they didn’t recover for four days.
