RAW SALMON

Raw Salmon is a raw-material trade: villagers pay emeralds for it, which makes it a candidate for an automated emerald farm rather than something you purchase back.

Raw Salmon is uncooked meat, normally dropped by farm animals. Selling it to a Butcher turns surplus animal-farm output straight into emeralds.

Only the Fisherman deals in it, so any trading hall that supplies Raw Salmon is built around that one profession. Raw Salmon can also be obtained outside of trading, but buying it from a villager is often faster than gathering or smelting the ingredients yourself.

To sell Raw Salmon for emeralds, bring it to a Fisherman at the Journeyman tier (13 units per 1 emerald).

On the supply side, Raw Salmon is worth one emerald per 13 units at its best rate (the Fisherman). That ratio is what decides whether farming raw salmon for currency is efficient: the fewer units a villager demands per emerald, the more valuable each one is to produce. A buy slot like this can be used 16 times before it locks and the villager has to restock, capping how many emeralds one villager returns per cycle before it must work at its job site again.

Since no villager sells raw salmon back, this is a one-way emerald faucet: you supply the raw salmon, the villager supplies the emeralds. That makes it a prime candidate for an automated trading hall, where a renewable source of raw salmon feeds a row of villagers and steadily converts your surplus into currency you can spend on the gear and rare items other professions sell.

Every Raw Salmon trade follows Minecraft's standard supply-and-demand rules. A trade can be used a limited number of times — 16 for the slot in question — before it greys out and locks until the villager restocks. A villager restocks up to twice per in-game day, but only if it can path to its job-site block and "work" there, which is why a trading hall must leave the workstation reachable.

When you sell raw salmon to a villager, completing that trade is what grants the villager career experience and pushes it toward its next tier. Spreading sales across several villagers of the same profession multiplies both your emerald throughput and how quickly the hall levels up.

One caution: the first trade you complete with a fresh villager permanently locks its current offers, including the raw salmon slot at whatever price it rolled. If you are chasing a specific price, decide before you trade, because there is no re-rolling a villager once it has done business with you.
