In Norway, laser weapons are being used to remove sea lice from farmed salmon. The Stingray Laser System uses cameras to scan the fish, identify lice, and then deliver a laser pulse to kill them.

I’ve always thought a stupidly expensive but cool and helpful device would be a tabletop mosquito/fly/wasp killer that shot lasers at said insects. I’m very happy to see there is an underwater version that seems to be really effective

They exist in trials. The human danger is too great though I think. If the laser thinks your eye is a fly for a split second, game over for vision.

A laser that can kill a fly in the fraction of a second has to deliver enough energy to fry your retina even though a dozen sunglasses. Also consider that the laser is focused down by the lens in your eye which greatly amplifies its power.

aramova@infosec.pub · 12 pts · 1y (5 replies)

That's not how specific wavelength safety goggles work. You can get both near UV blue light 440nm 5 watt goggles, and infrared depending on the laser.

Problem is they tend to shift the color of light for everything so much that they aren't pleasant to wear for a long time.

My worry would be getting hit on the skin, a 5 watt 440nm laser hurts, and it's a deep burning pain that doesn't go away.

Why even pretend my reply was about safety goggles? Obviously a huge difference vs regular sunglasses.

Zaphod@discuss.tchncs.de · 4 pts · 1y

I think it wouldn't be a device to have on passively. Just something to turn on when you need it, like a vacuum. So you can just put safety glasses first.

Fish farms are one of the most 'boring dystopia'-moments in existence. They are bad for the environment, breeding disease like it is their main job, they are cruel as fuck (imagine factory farming could layer their animals on top of each other) and most fish end up dead. It is funny how people instantly close their eyes when we are barbaric as fuck towards "food"-animals, like they do have no place on this planet but on our plates. The same disgusting mindset that has let us to another mass extinction.

That's an antiquated reality. It should be a mRNA vaccine or perhaps some kind of nanobot that kills these parasites.

I was thinking of Sterling's Shaper/Mechanist universe, with the conflict being between genetic tinkerers and techno-upgraders.

You could blast the parasites with lasers on drones. Or engineer better fish immune systems.

Seems to be something unrelated to this here. That system could never target such tiny organism, let alone have and impact at the flow speed. These fish are also not any of their hosts.

Tollana1234567@lemmy.today · 22 pts · 1y

it seems like a human created problem int eh first place too. when you farm salmon you have to do it in enclosed area, so this unnaturally density of the amount of fish per area is quite high, and parasites, and infections are spread quite easily. Alantic salmon is usually the only ones that can be farmed, other salmon species are much more difficult. wont affect parasites like parasitic cnidarians.

Given that the (Norwegian) Fish Farms on the coast of BC almost annihilated the natural salmon due to the lice and other ecosystem damage, something to destroy the lice might be a little bit helpful. Although it might only be helpful to the penned fish and not the surrounding environment.
