It's the large haddock collider.

I'm more confused about the fact that the salmon go in backwards

[–] Janx@piefed.social 54 points 2 months ago (2 children)

Once inside, they instinctively swim against the strong current of water rushing downward. That means they end up moving backward down the spiral, eventually getting pushed out the bottom of the helix into the river.

This method has lead to better survival rates than when the fish were spilled over the top of the dam.

The salmonplexer

[–] Tolookah@discuss.tchncs.de 13 points 2 months ago (1 children)

It's actually a salmon decimator. 1 in, many out

[–] Asafum@lemmy.world 17 points 2 months ago (2 children)

Check the arrow direction, it's a salmon smasher!

[–] Tolookah@discuss.tchncs.de 10 points 2 months ago

Their tails deceived me!! This large salmon collider will hopefully find the Biggs Bass-n particles that fishermen always say got away.

[–] igmelonh@feddit.online 9 points 2 months ago

Yeah, though I can see how it looks like it's going the other way at first glance, what with the fish facing the wrong direction.

Salmon Multiplexer

[–] Evil_Shrubbery@thelemmy.club 17 points 2 months ago* (last edited 2 months ago)

The Fish Cannon 2000 is a hydraulically, electrically, or pneumatically driven, six-barrel, water-cooled, electrically fired Gatling-style rotary cannon which fires fish caliber fish at an extremely high rate (typically 6,000 rounds per minute). The FC2k and its derivatives have been the principal cannon armament of United Fish States military fixed-wing aircraft for over forty years, as of the turn of century.

Each of the cannon's six barrels fires once in turn during each revolution of the barrel cluster. The multiple barrels provide both a very high rate of fire—around 100 fish per second—and contribute to prolonged weapon life by minimizing barrel erosion and heat generation. The average time between jams or failures is in excess of 10,000 fish, making it an extremely reliable weapon.

Salmon Accelerator

[–] Diplomjodler3@lemmy.world 10 points 2 months ago

Fish comes in, fish goes out, you can't explain that!

[–] RiceMunk@sopuli.xyz 10 points 2 months ago

You use this to combine several C-tier fish into one B-tier fish, or split a B-tier fish into multiple C-tier ones. Or same with other adjacent tiers, though there's some additional inefficiency penalties with higher tiers.

It's pretty useful for compact setups where you need a specific tier of fish, but it's much more efficient to collect all types fish and implement some filtering logic to route them by tier to where they're needed.

The all new Fish++ turns six backwards fish into just ONE, which is just so, so fishy.

With the machine completed, the messiah had automated his primary task and was thus terminated for redundancy.

The sharknado guard dissolves the sharknado by guiding the flying sharks into the inner screw structure, forcing them down and safely into the sea. A few perfectly placed sharknado guards can reduce a small to medium sharknado to a normal shark-less sub EF3 tornado, saving many lives in the process.

the fish multiplier

EDIT: id like to correct my catastrophic misunderstanding of the above structure, as this is, in fact, a fish divider

Nvidia's new GPU cooler has an eco mode that doubles as a Salmon spa and amusement park. Warning, it doesn't fit in a standard ATX case anymore and will require an upgraded power supply.
