The Probably Stolen aquafarmer guide starts at Wild's Network: unlock the Retired Aquafarmer, obtain a basic recirculating tank, tilapia and fish food, then maintain water quality, filtration and power until the fish reproduce. Fish farming is in the October demo; it becomes a 1.0 starting scenario.

Probably Stolen aquafarmer guide: first tank
Access the retired merchant through the Wild's Network upgrade.
Set up the basic circulation system and place the starter tilapia in suitable water.
Stock food and keep the tank's energy cell charged so circulation continues.
Check water quality and filtration before adding more fish.
Watch for roe, then give the eggs time to hatch into fry and mature fish.
Keep fish alive and breeding
Different species have different habitat needs. Tilapia are the starter stock; eels and sturgeon are more valuable later species. Tank upgrades require materials, so check the current upgrade prompt before committing a rent reserve. For the shared input, power and storage decisions, see the production-chain checklist.
Harvest the output
A knife butchers fish for meat. Sturgeon can also provide caviar when worked with Surgery Tools. Harvest only when the fish is at the intended stage; leaving enough breeding stock keeps the cycle operating. Aquaculture is slower and needs less maintenance than rat ranching. Compare its output over several shop days instead of expecting same-day sales.
