Night Fishing

Author: Hugh Bollinger/Friday, October 24, 2014/Categories: photography, space science, marine life, sustainability, environment

Some fisherman use trained birds to do their fishing while others use hooks and lines. Who would have thought some fisherman in Asia used lamps at so bright they could be seen at night from space? Recently, a photograph was captured by the International Space Station as it passed over the Tsushima Straits between Japan and Korea.

Commenting on the space station photo NASA said:

"The fisherman are likely luring Todarodes pacificus—the Japanese flying squid—to the surface with bright xenon bulbs. The city lights on the Korean side of the strait have an orange glow, while those on the Japanese side are greener. The difference is related to the distribution of lamps using mercury vapor, metal halide, and high-pressure sodium—the bulb types most often used for street and outdoor lightning. Mercury vapor lights tend to be green, high-pressure sodium is orange, and metal halide lamps are bright white."

NASA didn't say if the night fishing was successful but considering the density of boats the squid are likely on their way to joining the long list of endangered species.
