Fish dying out

[Craigjw]

I have automated fish breeding ponds and 1 stock pond.  The stock pond, has no food intake, the only input is eggs, which hatch in the pond and I'm removing all Egg shells, polluted dirt and meat.

Why is the population dying out in the stock pond despite my efforts to repopulate? 

Should I not be removing the meat from the pond perhaps, do the pacu eat this to maintain sustainability?

Unless the pacus are overcrowded, they should be able to keep a stable population. Even without food intake.

Show us some screenshots maybe.

The fish have the overcrowded debuff.  The population was at least double what is in this screenshot a while ago.

Your problem is likely that you're feeding tame eggs into the unmaintained pond. Tame eggs will hatch into tame fry, which become overcrowded and will not reproduce.

If on the other hand you collect WILD pacu or wild eggs and put them all into a pond in the wild (not a stable), they *shouldn't* over-crowd and will probably sustain their population even if you let them go hungry. In fact, each lifecycle you have a chance of the population going up.

Unless they changed wild pacu behavior, this was the way last time I tried it. Unfortunately there's no way to make a tame critter go feral and produce wild offspring, so, you might have spoiled your map already.

As far as i understand it, overcrowded critters dont reproduce.

You either need to increase the size of your pool or use two pools as explained in

I still have wild pacu scattered around the map.  the other solution is to just make more ponds for the tame pacu.

The only debuff stopping them from reproducing is expecting.

Overcrowded is a happiness debuff.

Glum is a metabolism debuff.

There's 16 tame Pacus in that puddle.

I read that entirely and can't find why the second pool doesn't make the pacus overcrowded. Is it because it is not considered a stable ?

What are the conditions to have this debuff ? Could you explain it please ?

You only trigger when the critter is in a room, and sum of all critter and eggs required spaces are more than size of the room. For example 2 hatches and 1 egg in a 35 size room. (hatches require 12 space each)

My fish happily reproduce in that puddle because it's not enclosed in a room.

Oh so it's a bit like a bug. I've read somewhere that pacus needed 4 tiles of water to be happy. I think the game considers only tiles and not water tiles ^^
Thanks for the briefing !

It's 8 tiles. They don't need to be happy to reproduce though as you can see in my screenshot.

Just to clarify: if they are happy you'll get more eggs. When they're not happy they lay just one in their lifetime.

I told you in the other thread about pacu farms, you need to remove the eggs from the pool to prevent the fish from having the "expecting" debuff and stop replacing themselves 1 for 1. Overcrowded doesn't matter here.

I wouldn't mind if they replaced themselves 1:1, but they aren't.  I'll reintroduce the incubation ledge to the pond and see how that plays out.

[Mariilyn]

I understand now. 

The Overcrowded debuff is based on the number of tiles of water in the pool. (Btw each pacu needs 8 tiles of water.)

But for the Expecting debuff, all the space in the room is considered. (Each pacu and each egg need 8 tiles of space in the room.)

However, if you have an advanced colony (1000+ cycles), you may have reach the ONI Twilight Zone and it's possible the pacus stopped laying eggs because of lag or something.

So much misinformation about Pacu from the community. Stop perpetuating these myths. Pacu don't behave like the other critters. They don't get "expecting", and "overcowded" does not prevent them from sustaining themselves. "Tame" makes no difference either. Anyone that objects to these facts needs to test it themselves.

1 tile of 350kg of water can sustain hundreds of "tame" Pacu without any issue. They can't multiply, but they won't die off overnight.

OP might have some dying off due to temperature. Unfortunately they have something like 2-4% chance of laying an egg that won't survive the temperature for long after hatching.

Or maybe you never made a pacu farm in a closed room/open but small space so you never got the expecting debuff yourself and didn't lose half your fish rapidly. Who's misinforming then ?

My experience seems to fit with your explanation Mariilyn.

Don't embarrass yourself. We are done talking until you provide a recent screenshot showing a Pacu with "expecting" and showing that it has 0% reproduction rate because of it. I don't think you'll be able to deliver unless if you mod your game.

I wrote this post, as that's exactly what I'm experiencing.  I have a clean, un-modded game and am on cycle ~550 on survival, without sandbox.

I have 3 reproduction plants and a stock pond, my stock pond, which excess pacu eggs get sent to has lost population.  The temperature in the 4 ponds are 35-40 C and they are all tame pacu.

Please don't digress into posting inflammatory comments regarding other peoples input into this conversation, as it's not helpful.

[PhailRaptor]

Just want to point out that it's possible for any Pacu to drop a Gulp Fish egg.  Gulp Fish require quite a low temperature to survive, relative to Tropical and standard Pacu.  This means that any Gulp Fish that spawn in the stock pond will die pretty quickly after hatching.

Have we discounted this as a possibility?

Hmm I usually take the time to check in-game before posting something.

 

 

Seems like an oversight ; logically the expecting debuff should be working the same as overcrowded. Confined debuff also happens when the pacu is in a room smaller than 8 tiles instead of a pool smaller than 8 tiles of liquid.

 

 

[Nxf7]

Great so they do get Expecting if they are in an enclosed room that is small enough. Thank you for providing proof @Mariilyn. Sort of makes it a non-issue then when the fix is as simple as ensuring the room isn't closed off. I like that idea much better than sweeping the eggs out.

Right, next time take the time to check what you claim before accusing people ?

Yes some fish dye even in mariilyn version of fish-omatic, so I improve it whit a door . Instead of arguing is better to try to find solution. If i didn't try to improve the existing design, the bug whit the restricted area of pacu whit meshed tiles isn't known until today.

If i didn't find the regolith problem, we can't find better solution. I think i find the easiest solution for melting the regolith and faster than 100 kg / 75 seconds, but i need to test it when i am at home.
