Transport Fever 3 Fish: How to Set Up a Fishing Route

Fishing is one of the trickiest new industries to crack in Transport Fever 3. Fish can't be loaded or unloaded the way you'd expect from earlier games, and the rules around ports, warehouses, and line configuration trip up nearly every new player — including Urban Games' own developers. This guide walks you through the entire Transport Fever 3 fish supply chain, from prospecting a fishing ground to delivering the catch to a hungry town, based on gameplay experience and community reports from launch week.

Why Transport Fever 3 Fish Works Differently Now

The single biggest change: ports and stations no longer store cargo. In Transport Fever 2, you could dump fish at a port and sort it out later. In Transport Fever 3, cargo only unloads if it has a valid destination — a factory, an end consumer like a town's commercial district, or a warehouse.

Urban Games developer UG-Sam confirmed this on the official Steam forums, coining what became a community running gag: "Welcome to the Fish Warehouse club." Even he admitted he confidently reported ports as broken when his fish wouldn't unload during his first playthrough. If you're staring at a cargo boat that refuses to drop its load, you're in good company — and the fix is simple.

The Golden Rule of Fish Logistics

Every fish shipment needs a destination chain:

Step-by-Step: Building Your First Fish Route

Here's the process, distilled from gameplay experience and player reports, broken into clear stages.

Step 1: Prospect for Fish

You unlock fish prospecting by ranking up from junior to the mechanic tier. Once unlocked, open the prospector tool and select a town to scan for unexploited fish occurrences nearby. If nothing turns up, prospecting can effectively force a new fishing ground industry into existence — a neat mechanic that lets you shape your map's economy.

Step 2: Place Your Port and Ship Depot

Choose the nearest coastal town that already consumes fish — check the town's supply panel; fish goes to the commercial district. Then build:

Step 3: Configure Your Lines Correctly

This is where most players fumble. You need two separate cargo lines, and both must be told to load fish, not passengers:

• Ship line: set to load fish at the fishing ground and unload at the cargo port. Player experience shows the most common error is reversing these — boats try to load fish at the port instead of the fishing ground, resulting in the "cargo type cannot be loaded anywhere" error.
• Truck line: set to load fish at the universal cargo station near the warehouse and unload at the town's commercial district.

A community report from the Steam forums highlights a second classic mistake: setting the line to "load" at the delivery stop instead of "unload," so trucks drive around forever with cargo still aboard. Always double-check the load/unload toggle at every stop.

Step 4: Specialize Your Stations

Universal cargo stations accept everything but load slowly. Once fish starts flowing, upgrade one terminal to specialize in fish — this boosts loading speed for your trucks. You can also configure stops to unload on both sides by selecting alternate terminals, which keeps traffic moving in busy towns.

Sending Workers to the Fishing Grounds

Fishing grounds (like all industries) produce more when workers are delivered. Community-documented setups show a two-leg passenger route does the job:

1. Road leg: passenger stop in the town's residential area, connected by a passenger road line to the port.
2. Water leg: a separate passenger boat line from the port to the fishing grounds. Keep it distinct from the cargo fish route — a cargo boat will not deliver workers.
3. Assign vehicles to both lines. A line without vehicles moves nobody.
4. Verify in the Boosters panel. Once workers arrive, the worker booster turns green, and player reports show efficiency gains of up to 140% when combined with other inputs.

Profitability: What to Expect

Is fishing worth the investment? Based on one player's documented campaign, yes — the shipping route turned profitable once deliveries stabilized, though road networks out-earned it. Key takeaways:

Don't rush a second fishing route. One gameplay example showed the first ground didn't produce enough surplus until workers and efficiency boosts (tools, fertilizer) ramped up production. Grow the town first — more residents means more commercial demand and fuller passenger lines.

Common Fish Problems and Fixes

If demand is genuinely full, the developer suggests clicking supplied buildings to confirm — towns consume fish over time, so patience or a second consumer town solves it. It's also worth noting fish feeds into the canning factory chain (fish + meat + sheet metal = canned food), which towns like the largest cities demand as they grow.

FAQ

Why won't my fish unload at the port in Transport Fever 3? Ports no longer store cargo. Build a warehouse within the port's catchment area so the fish has a valid destination, then have trucks pick it up from a nearby cargo station.

Do I need a special boat for fish? Cargo boats that list fish as a carried good work fine — a small 20-capacity vessel is plenty for a single fishing ground. For workers, you need a separate passenger boat line.

How do I find fish if none spawns near my towns? Rank up to the mechanic tier to unlock prospecting, then scan near a specific town. Prospecting can reveal — or even help establish — unexploited fish occurrences.

Is the fish industry profitable in Transport Fever 3? Community reports say yes, once the route stabilizes. It typically earns less than road cargo, but it grows towns, feeds the canning industry, and pairs well with passenger lines to the same destinations.
