Aquaculture: Tilapia → eels / sturgeon
Upgrade Wild's network to unlock the retired aquaculturist and buy tank equipment from them.OfficialVerified parts of the chain:
- Start with TilapiaOfficial, then advance to eels and sturgeonOfficial.
- Keep water quality, filters and the energy batteryOfficial running.
- Adult fish lay eggs that hatch into fry.Official
- Harvest with a knifeOfficial for meat and special resources.
- Using surgical tools on a sturgeon harvests caviar directlyOfficial — the high-value product the developer highlights.
Compared with rat farming, aquaculture runs slower and needs less maintenance, which suits players who do not want constant feeding and droppings management.
Water: Aquascan and 98% purification
The water route is about purity and labelling:
- Scan containers with the Aquascan to read purity.Official
- Purify above 98% using filters and the Hydratech Micro Purifier.Official
- The UV-Filter can only be used on items you own.Official
The risk of relabelling and passing off inferior goods is covered in Appraisal: How to Spot Fake Cigarettes, Water & Rare Goods.
Bottle Printer and Vacuum Robot upgrades

Toolbox and vending machines
