Fish-delousing underwater laser (2018) [video]
- whiw 2y agoIf the laser is powerfull enough to kill sea-lice then how does it avoid blinding the fish or giving them retina burn?
- thatguy0900 2y agoAs long as the fish can still find food that might not matter in a farm environment
- whiw 2y agoThat seems a somewhat callous disregard for the fish, blinded and swimming around with itchy eyes from burned out retina.
- thatguy0900 2y agoYeah, it's definitely unethical. I doubt the farmers care though
- walterbell 2y agoOnly available in Norway, https://www.stingray.no/delousing-with-laser/?lang=en https://www.stingray.no/delousing-with-laser/?lang=en > technology combines stereo machine vision, advanced software and high-precision laser to target and kill parasites that infect farmed fish.
- Grosvenor 2y agoThis is exactly the sort of thing I got into tech for. Real world, no bullshit solutions to problems. I love it.
- jniles 2y agoI would love to see more data on this. Their site makes some bold claims, but it is hard to know how to quantify the effectiveness of the laser treatment, How many units do you need per X fish? After how many hours/ days/ weeks does it take to reduce the parasites to X levels? Not critiquing the technology, just hard to visualize as someone with no knowledge or experience in the field.
- chriscjcj 2y agoWhat are the falling pellets?
- dvh 2y agoIt concentrates fish on one spot
- ThePowerOfFuet 2y agoFood.
- cassepipe 2y agoSea lice I assumed
- nomilk 2y agoTitle was a little confusing; Stringray is just the name of the laser, which is being used to remove sea lice from salmon. Very cool.
- dang 2y agoStingray removed from the title above. Thanks!
- xeonmc 2y agoCan they be mounted on sharks?
- igorkraw 2y agoIn the beginning of the PhD, to help with rent I contracted to help develop computer vision algorithms in this field, only PoCs, never got very far. And interesting thing is that the lice apparently evolve super fast, including getting translucent and resistant against poison
- globalise83 2y agoThat's interesting! They might also evolve a tendency towards moving to the left flank of the fish.
- greggsy 2y agoFish are known to swim in both directions.
- ndr42 2y agoReminds me of the evolution of fish that prey on scales of other fish to have two distinct types with the mouth on the right or left: https://en.wikipedia.org/wiki/Perissodus_microlepis https://en.wikipedia.org/wiki/Perissodus_microlepis Depending on which type is more frequent the other is more successful because the prey is more cautions on the other side... edit: spelling
- globalise83 2y agoMy comment was half in gentle jest, but you have really found a relevant example there - thanks for sharing. I guess I have a potential PhD project if I ever want to get into maritime biology: "The Dark Side of the Fish: How Crafty Parasites Outmaneuver High-Tech Pest Control"
- internet_points 2y agoLice are a huge problem. If this solution works, it must not be implemented that widely. The news is full of solutions like physical washing, thermic treatment (basically hot baths), loads of chemicals, also huge amounts of chlorine poured into surrounding rivers because the fish escape the farms and spread lice. The lice are really adaptive. There are more and more lice due to higher sea temperatures[0] and increased resistance to treatments.

- internet_points 2y agoPretty good summary! I somehow forgot about the cleaner fish :)
- James_K 2y agoThe hyphen makes all the difference here.
- amelius 2y agoIt would be more interesting to see what the camera of the system sees.
- codr7 2y agoThere are plenty of other problems with keeping fish in concentration camps. Industrial approaches applied to living beings are just nasty, period.
- metalman 2y agooh man dont I just love lasers, just saying laser makes me feel good, more laser and dont I hate parisites and vermin, laser, zap more zap, less horrible blood suckers, and vermin got a small hobby farm....wont use poisons...so I know, probably not going to get rat lazers, but laser powered rat detectors before it gets all kinetic on there dirty rat asses...,snacks for the ravens
- amelius 2y agoIs that safe? What if someone falls into the tank?
- dddw 2y agoDeloused in the Oceaneum
- brian_herman 2y agoI wonder if this feels good for the fish?
- essi_ 2y agoHeard about this several years ago and while it's very cool technology, it's sadly also like putting makeup on a pig. Fish health in those tanks is terrible. The entire idea of farming fish is terrible. The best idea they've come up with so far to avoid sickness is moving those farm tanks onto land so they can be as controlled as possible. I find it to be a bleak industry. https://www.vetinst.no/nyheter/fiskehelserapporten-2022-intensiv-produksjon-og-avlusningsoperasjoner-oker-helse-og-velferdsproblemene-i-lakseoppdrett https://www.vetinst.no/nyheter/fiskehelserapporten-2022-inte...
