fish depletion?
« on: February 18, 2016, 01:03:13 pm »

so on my units screen i can see that there is a certain amount of fish in my fort, if my fishers catch all of the fish is my supply gone for good?
do i need to let the fish repopulate before i catch more or will more spawn in the river (which is where they are fishing from)

what about fishing in the caverns? do fish just infinitely spawn or do they need to repopulate?

IICR, local fish spawns from water biomes are limited by population. 

This is different from the fish caught in Fishing labor--those are vermins that respawns even on dorf-made ponds.

The fish that fisherdwarves catch, like salmon, rainbow trout, steelhead trout, mussel, char, shad, pond turtles etc, are basically aquatic vermin that spawn in water bodies like oceans, rivers, brooks, murky pools, cavern seas and even in dwarf-made channels or artificial rivers.

As I understand it, oceans, rivers and brooks have an renewable supply of catchable fish, so if you're fishing from an actual ocean/river/brook tile then you will pretty much never run out.

Murky pools have a limited supply of catchable fish, generally turtles. If you're fishing from one of these, or if you're fishing from an artificial channel or river (which are treated by the game as the same as murky pools) then you'll be drawing from this limited pool of catchable fish, and within a few years or even seasons you should exhaust the supply. Keep in mind this happens even if you fill your artificial channels with water from a river or brook.

I'm not really sure about cavern fishing and whether it's renewable. Still, it shouldn't take too much effort to wall off a little section of it and build a few fisheries, so it might be worth doing that for a bit more food variety.

When you mention fish in the units screen, are you talking about stuff like carp, longnose gar, pike, sturgeon etc? Because those aren't vermin fish, they are normal creatures like the above-ground animals. When they die, they leave a corpse to be butchered. They can't be caught by fisherdwarves, and historically it's usually the reverse that happens. If you want to eat them, find a way to lure them into a chamber and then drain it of water. They air-drown and die, then you butcher them for meat.

carp seem completely docile now, i havent had a single carp attack ever since 0.40 came out
but yeah its mainly carp and lungfish, ive noticed that those give birth and have fry, dose this mean i could catch them and make a farm of sorts with them?

basically im having the issue of a dwarf strange mooded and i had to wall off my farm so now i need other sources of food for the time being

Yeah, I somewhat miss the good old days when fishing from a river was suicide. Hell, I miss the old cavern creatures too, now it seems a lot of them don't even aggro. A cave crocodile actually RAN AWAY from an untrained peasant recruit I sent out as bait. Then I had a bunch of troglodytes roaming around harmoniously among my dwarves in the caverns for a while.

Admittedly a couple of them eventually did attempt to disturb my dwarves after all their buddies got accidentally caged. Unfortunately the dwarves they chose to attack were an axe lord and a mace lord...

but yeah its mainly carp and lungfish, ive noticed that those give birth and have fry, dose this mean i could catch them and make a farm of sorts with them?

It would take quite some effort to catch and breed carp I imagine. You'd probably need a setup like that sea serpent farm.

I've seen quite a few caged troglodytes giving birth, so I'm not sure if breeding in cages is a thing now. If so, then that would make carp breeding a lot simpler, but you'd still need to figure some way to cage them in the first place. Not really worth the effort, but hey it'll be fun.

Lungfish are vermin as per the wiki, so I suppose they can be caught by fisherdwarves. If they aren't....well I'm sure *something* should be catchable to keep your fort from starving while your farms are locked down. Just designate a part of the river as a fishing zone and get a few fisherdwarves. Try and build your fisheries and raw fish stockpiles near the fishing zone, so that your fishers don't have to walk so far between each catch, this makes them a lot more efficient.

How did you end up walling off the entire farm? I imagine just walling around the dwarf's claimed stockpile would have been enough?

the clothiers workshop is directly adjacent to the farm so i couldent wall around it, either way it didnt matter, we went stark raving mad so no harm done

You don't keep a year's supply of prepared meals on hand? I'm not sure exactly how long my usual stock would last, but given my usual backlog of stuff ready to be cooked in addition to my usual stock of prepared emails, I'm pretty sure I could outlast a dozen failed moods without access to my farms. At least after the first year or so.

Plus, there are the turkey eggs, and I could butcher an extra pig or two. And if I really get desperate, those sheep/llamas/alpacas can be used for more than just wool production. Or a few turkeys could go into the pot. Or send out a hunter or two. Or a herbalist. Heck, the only thing I really need my farms for is booze production, and that could also be handled by herbalists in most biomes (assuming it's safe outside).

Why do I even have farms, anyways? After the first year I'm usually swimming in food.

Have them killed. Nothing solves a problem quite as effectively as simply having it killed.

im not even through the first winter yet, i just made this fort last night and havent played much on it

im trying to find a good world that will give me a lot of fun, tbh ive never actually HAD a gobbo siege, ive either got wrecked by wearbeasts the instant i embark or the embark is perfictly peaceful and i never have any enemies whatsoever and all my dwarves wander the caverns unarmed and come out without a scratch
