Might still be possible to redirect them to an interior pool for safe fishing at your leisure. I know I've seen clumps of salmon hanging out in pools before, and if they're connected to my internal well my dwarves can fish from inside the fortress.

Not sure if they'll eventually migrate away via teleportation, though. Might be worth testing.

Do weapon traps work on fish? Because I'm imagining a section of the river blocked off with floodgates, but flowing down through a channel filled with weapon traps. It would end at a fish collection area covered in grates, next to some fisheries. The good part is that water pressure would push the dead fish along after they get "processed."

Not sure this would work. I once tried to make a more efficient butchery by spike trapping horses, but the dwarves refused to collect the meat of the dead horses. Then I tried it again drowning puppies, but the dwarves again wouldn't collect the meat. At least with land animals, it seems dwarves won't butcher anything that wasn't killed by dwarfy hands.

As for whether once can redirect the fish swarm into a safe room for later fishing, again I'm not sure it would work. In my last fort I redirected a river into my castle and seperated my castle's water source from teh river with a grate, but I noticed fish were still getting in. Maybe a floodgate would work?

IIRC, no matter how you kill wild land animals, they can be butchered. But I'm not sure how it works for fish.

Yep, wild animals can be butchered no matter how they die.  Tame animals can only be butchered after being deliberately slaughtered at a butcher's shop.  And vermin (including fish) leave behind 'remains' if killed, which can't be used for anything.  You can only get food from vermin fish by having a dwarf performing the fishing job, and I'm not convinced that the fish returned from that process have anything to do with the vermin fish you see moving around in the water.

If the food-plan fails, just build a huge atom-smasher in the river instead. When the salmon-run occurs, pull the lever for a big red splat!

[MrWiggles]

I would create a hollow floor of the river myself with a fish basin under it. Then when the fish come, pull the switch and fish the fish at yer leisure.

Added a note on salmon runs to the wiki. I'm sure we can find out which token combination invokes this with a bit of science.

Moss doesn't really do anything but sit there.  But it's really hard to actually see it in Fortress mode - you have to have a fort that lasts something like 15-20 years (my 13 year fortress doesn't have any moss yet).  So it took a long time to discover (since most forts don't last longer than 5-7 years).

Moss only grows on constructed structures, outside, after a long period of time.

The fort doesn't have to SURVIVE.  Moss will grow if you make enough time pass by abandoning and reclaiming the fort (or starting new forts then abandoning them) repeatedly.  I did one of those when I learned about moss so I could see it for myself.

Agh, i just missed the spring run, so no video. I'll try and catch the autumn run.

I only noticed when i realised my two novice fisherdwarves were running up to the river, catching fish instantly and then running back to the fort with a shad. My poor fish cleaner.


This map appears to have a bounty of vermin; there are regular clumps of a dozen+ Toads hopping about, yearly batsplosions from my fort entrance, the salmon runs, the mussel swimming around in the river. Lots of dragonflies around the river and small flocks of birds, and that's just everything i noticed while not really looking.

I'm kinda happy my cat died to Fire Imps now; all these vermin make the place much more lively and interesting to watch. Although no doubt it won't be long before some useless immigrant arrives with a pet floofy.

Caught the tail end of the Autumn run on tape.

The Autumn run goes downstream, while the Spring run goes upstream. The runs definitely appear at one end of the river and then flow down to the other end, unfortunately i was faffing about with the video recorder (never used it before) so i didn't manage to record the start of the run.

Now setup a system to drain the river, killing the fish.  Then you send in hordes of butchers to create a massive fishing industry.

We've already gone over this; they're vermin fish, have to be fished, not butchered.


Fishermen do appear to catch Shad instantly when fishing in the river during these runs though, so a small horde of Fishermen would seem to be a good way to feed the fort, at least for a short while until the fish run out.

You could set a food stockpile to only accept raw fish next to a fishing zone with zone only fishing turned on. Your dorfs would just have to take a few steps. You would probably want a stockpile of barrels close by too.

I'm just glad for your dwarves thats not a carp or sturgeon run.

[bombcar]

I wonder how many other things Toady One is just waiting for us to find.
