Harvest Moon: Echoes of Teradea Cod is one of the fish that share a spot with other species rather than having a spot of its own. There are exactly three Cod fishing spots in Teradea, each of which yields three species, so Cod is never guaranteed on any single cast.

Harvest Moon: Echoes of Teradea Cod and its three spots

#SpotPositionAlso caught there
1Desert157 m northeast of Great Sand SeaRound Herring, Red Seabream
2Quarrytop, Frozen Galaxy Labyrinth304 m northwest of Sacred Sanctuary of the Great IcefieldSaffron Cod, Pollock
3Quarrytop, Frozen Galaxy Labyrinth217 m north of Sacred Sanctuary of the Great IcefieldBlack Seabream, Continental Lobster

Two of the three sit in the Frozen Galaxy Labyrinth, in the same area, so they are one trip: work the 304 m spot, and if it gives you Saffron Cod and Pollock but no Cod, step to the one 217 m north.

The bait Cod takes

Cod are attracted to Ragworm, Cut Bait and Peeled Shrimp, and any of the three works.

The Saffron Cod in the icefield is a completely different fish and will not count toward a request, so do not hand one in for a Cod request.

Why you need Cod

Paul's Quarrytop Chapter 2 request is 15 Iron, 2 Cod and 6 Leek for the Huge Hot Pot Festival, so two Cod is the whole ask. The full list of requests is on the villager requests page.

Working a spot

Stand on one of the three spots and use Ragworm, Cut Bait or Peeled Shrimp; the minigame controls and the timing are on the fishing page. If you get one of the other two species, cast again — Cod is one of the three species on the spot, so work the spot until Cod turns up rather than moving on after one cast. The four walleye spots follow the same rule.
