TIL fish can get lice
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.
Boston Legal don’t see this coming
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.
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.
screw that, we’ll just wear sunglasses indoors and look supercool and mosquito free
Don’t mess around with the guy in shades, oh no.
🎶 I wear my sunglasses at night 🎶
The future’s so bright, I gotta wear shades
Damnit! Now I’ve got the song stuck in my head.
You’ve got it made with the guy in shades, oh no.
Spotted a Canadian!
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.
yeah well I’ll just wear two dozen sunglasses. that’ll make me twenty four times as cool as you, Mir Science Man.
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.
I thought it was obvious I meant laser safety glasses.
With the line about looking cool wearing them indoors??
A angle laser is nowhere near as fun as an array of lasers anyway
So many ways to engineer out that hazard.
Last I understood was it’s been patented 10 different ways from Sunday, and prototypes are just sitting on shelves, collection dust.
So now the fish are lice free, but blind? D’oh!
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.

2 days left to back. Get it while you can!
LOL, $600 for something that is unproven and has a high chance of being just a scam?
Shhhhhh. I’m sure it will be a legit as StarCitizen!
Hey at least SC has a playable demo that’s occasionally fun to play (I got a free code with a piece of computer hardware a while back and haven’t spent a penny on the game otherwise)
Neat! Though I’ll probably wait until people say it works well and doesn’t accidentally burn out your retina
Can you image what kind of cult these fish will create?
ALL HAIL THE PILLAR OF CLEANSING
Frank was zapped! HE IS THE CHOSEN ONE!
Now THIS is the cyberpunk reality I want to live in!
That’s an antiquated reality. It should be a mRNA vaccine or perhaps some kind of nanobot that kills these parasites.
That’s not cyberpunk though, more solar punk imo.
Cyberpunk is all about unideal but pretty optimal solutions.
That would be just good old plain sci-fi, no punk in that.
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.
Bio punk?
say AAAAAAAHHHHHHHHHHHHHHRGGGHHH
AAAAAAAAARRRRGUUGGUGHHRHEGEHHHHH
Haha, that is such a cool use for laser technology and also the fish look like they are clubbing. Thanks fo sharing :)
Why is it I go straight to “some fascist government is going to set this up on the street and just laser undesirables”
I can see a day when we the non-rich have tattooed barcodes, implanted chips, and god knows what else about our persons, we will be scanned to death, system would choose who to zap (kill) or just persecute in some manor.
I had this job where a idiot director thought about forcing us workers to wear wrist bands with barcodes, our timecards have same barcode, everything we do is tracked by barcodes, thankfully was rejected…but upper management considered it to much for us workers comfort 😞
Except it clears acne and keeps people clean-shaven. Unfortunately it doesn’t work for some minority subset due to skin, hair color, or some other overlooked bias. Ultimately leading those individuals to fail job interviews and such. Leading them to a life of meager success compared to the majority.
TIL: There is sea lice.
New terror unlocked.
Don’t look up what replaces a fish’ tongue, then…
Although it’s technically not lice, this is called swimmer’s lice in many languages.
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.
Yeah, video is about salmon louse: https://en.wikipedia.org/wiki/Salmon_louse
They are 5-18mm depending on sex and such.
Oh totally, wasnt saying they were the same. was just adding an interesting thing to the discussion.
flatforms, and thier eggs ar epretty microscopic, the lasers would be ineffective here. best not to swim in places where the flatworm exists.
We are the Borg, resistance is futile.
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.
This on a small crawler to remove invasive species. Bad idea?
Like, humans?
