Automate Killing Pacu

[Dixon Sider]

Anyone got a good method for killing these guys quickly? I have a farm giving me like 10+ pacu per day and it takes way too long to kill them. I have thought about overheating them, but that seems kinda clunky of a way to kill them.

Also, it should go without saying, but I need the food to be edible after killing them lol.

Freezing and overheating are basically the only options to kill critters that can swim. I think pokeshells also attack other critters while they're aggressive, but that's obviously not viable.

Gulp fish will die at temperatures above 25 C, which can be reached with a liquid tepidizer. But then you'd need to cool the breeding tank or you won't get gulp fish. Overheating the pacus with an aquatuner is probably the better bet, since normal pacus can't be frozen to death with water as coolant.

If you put vacuum and insulated tiles over a pool of oil or some other liquid with a high boiling point, you'll keep the heat from escaping.

Now, if you're just looking for food and not pacu filets specifically, you could also use shipping to automatically bring eggs to an egg cracker, so long as you keep your dupes from binging in any eggs that you need to hatch into fish.

I tried heating, freeezing then pokeshells. The first two were surprisingly power intensive, so I wouldn't recommend them without some kind of heat exchange.
Putting a few wild pokeshells into the pacu-collection-area was my prefered solution. Depending on the amount of pokeshells there will not always be an egg and then pacus will accumulate, so it's not quite perfect, but it's cheap.

I noticed that the pokshell eggs stay incubating FOREVER, so maybe that is the way to go. I was thinking about killing 2 fish with one stone and taking my metal refinery waste to see if that will melt the fish. But that sounds a bit complex to automate and a nightmare to get initialized.

My base is far too new to be spending the fuel to heat or cool water to that extent yet. Automating pacu was literally the first thing I did after setting up my home base.

I didn't think about pokeshells. Thanks for the suggestions yall.

This is my current solution, and it made it a bit quicker than my farm was hours ago. I will probably poke around with the pokeshells soon. The trick is to swap the drop off points once my new fish get crowded

How insulated did you keep the heating chamber? The pacu isn't around for very long, and the filet they drop can't absorb much heat. I don't think it should require too much heat.

Hmm. If it is losing heat to the living pacu, maybe a freezing chamber with liquid chlorine would work better. The low thermal conductivity would mean the cooling could be off most of the time.

I had isolated tiles and vacuum.
I didn't experiment extensively, but if I had to take a guess I'd say the heat is wasted on heating up the living pacu. When it dies and turns into filet most of that heat is probably lost? But I didn't care to find out the respective heat capacities of pacu or filet to verify this, so my guess might be totally wrong.
I also had a very much over-sized pacu ranch. A sane size is probably more manageable.

thats where wild pokeshell (sani is op) have the over population paku end up in a tank with pokshell with eggs. pokeshell especiall sani shell are grat wild farm animals for this. low maintenance just need the sweeper to get their drops. when shell eggs are near they get agro and will kill any adult pacu in the tank. my last paku tank held 4 paku but all the overflow just flopped over to the sani tank , no muss no fuss already had automation for gathering their seafood in the sani tank. if your gathering poke shells from your map 6 or so shells should keep an egg being present most of the time. keep them in water for sanishells( more food less shell) ethanol for oakshell great for that decor or even power or even saltwater to to keep them pokes and a great source of lime.

just stick them in a box and wait for them to die?
they only live for 25 cycles...

Bad pacu go into the insulated cobalt volcano room

I kill them with radbolts.
Fish drops, a radbolt storage gets pulsed by a signal until the metamorphosis is complete.

I spent a bunch of time trying different automated configurations and I kept getting failures that would plug up the system, then I came up with this set up and just build it and ignore it. It sweeps everything into the one tile with the fish trap in it then you just set the critter drop off with what ever amount you want in the breeder tank and a dupe will keep it stocked up. The sweeper over the single tiles sweeps egg shells and meat off to processing.

I seem to recall some sort of contraption that's basically a pool of water within doors and when there's enough critters in the room the doors cycle closed from the bottom up pushing the water into a holding area so the fish are sitting on the topmost door until there aren't any more critters in the room, then the doors reset and the water floods back in.

maybe something like that.
