Cold Stream

Cold Stream puts you in charge of a cold-water recirculating aquaculture workshop raising Atlantic Salmon, Rainbow Trout and King Salmon.

Keep three water parameters in the safe zone at once: temperature, dissolved oxygen and ammonia. The nitrifying biofilter converts ammonia in real time while your fish breathe, eat and grow.

Drop pellets and watch the school hunt them down. Chill the tank, fire the O2 jet, and dose ozone or UV-grade sterilization when ammonia creeps up. Scoop out dead fish before they rot. Grade and transfer fish that hit the order spec, then get paid by growth speed and survival rate.

When a power outage hits, restore emergency aeration before the countdown ends or the grid failure will cost you the school.

Six real upgrades in the supply shop: Backup Generator, Precision Feeder, Online Ammonia Meter, Efficient Bio-Media, Pure Oxygen System and a Fresh Supply Contract. Every one of them works in game and is saved permanently.

Clean water earns quality bonuses and Omega-3 premiums. How many orders can your workshop deliver?
