«Cazapiojos»: the game in which you are the laser that removes sea lice from salmon

New free mobile game, no downloads and with a ranking: you are the laser of a salmon cage and you have to remove the sea lice without hitting the spots, the eye or the lumpfish. It is inspired by the robots that already do this job on farms in Norway.

A salmon crosses in front of the camera. On its side it carries a dark bug with two strings of eggs hanging. You touch it, a green ray comes out from the bottom of the cage… and the louse falls. The salmon keeps swimming as if nothing happened. 'Cazapiojos' is the new game in the games section. It is played on the mobile or on the computer, without downloading anything, and a game lasts about three minutes.

How to play

You are the laser of a salmon cage. The fish pass from one side to the other and some carry sea lice. Touch the louse and the ray removes it. But not everything dark is a louse, and that is the fun of it.
  • The small louse, recently attached and still: 30 points.
  • The young louse, which walks along the fish: 20 points, if you hit it.
  • The female with its two strings of eggs: 50 points, and the one that most urgently needs removing.
  • The black spots on the salmon's back are not lice: they subtract.
  • The eye, never. And the wrasse, the fish that eats the lice, either: it is one of ours.
On the scale with nothing, the ray bounces: nothing happens, but you lose the shot and the streak. Five hits in a row raise the multiplier.

Six days to save the cage

Each salmon that leaves with lice fills the cage a little, and a female that escapes fills it much more. If the bar reaches the top, it is time to take the fish out to the hot water bath and the game ends. Each day more fish arrive, faster and with murkier water. If you last the six days, clean season and a prize for how clean the cage is left.

What is real about it

The game is inspired by something real. On the salmon farms of Norway there are devices that hang inside the cages with two cameras: they recognise the louse on the fish that passes, confirm it in two images and fire a green laser pulse at it. The louse, dark, absorbs the light; the salmon's scale, shiny, reflects it. It is done because the sea lice has become resistant to several drugs, and because the other way of removing it, taking the fish out and giving them hot water or pressure jets, is so rough that many salmon die afterwards. The wrasse, a fish that eats the lice, is also used as a helper inside the cages.
At the end of each game, the game tells one of these facts. And if you log into your account, your score goes to the ranking.
