Yes, you can build a fishing pond
Carry water in a bucket
Scoop water with a Bucket and pour it into a pit (dug-out ground) at your base to make a fishing spot. Scooping does not use up the source water.
Special water keeps its fish anywhere
Acid, mold, shimmering, grimy and sea water, and lava, give their own fish wherever you move them. Normal water gives the fish of the biome it is placed in.
Catch every fish in one place
Line up different waters at your base and you can fish them all without traveling. Keep the waters from touching each other.
How to Make a Fishing Pond (Steps)
- Get a bucket: obtain a Bucket (how to get it).
- Dig a pit at your base: digging ground with a shovel leaves a pit. Dig it to the size you want.
- Go get the water you want: use an empty bucket on water to fill it. The water does not run out, so one tile can be scooped again and again.
- Pour it into the pit: use the full bucket on the pit. The water spreads into connected empty pits.
- Refill at home from then on: you can scoop from the water at your base, so you only need to make the trip once.
Which Water to Bring (Water Types and Fish)
| Water type | Where to find it | Fish you catch | Fishing needed | Strength | Notes |
|---|---|---|---|---|---|
| Normal water | The Undergrounds, The Forgotten Ruins, Azeos' Wilderness, The Clay Caves, The Desert of Beginnings | Fish of the biome you are in | Depends on biome (20+) | 1 | |
| Lava | Molten Quarry, some scenes in The Desert of Beginnings | Lava fish (anywhere) | 240 (only Galaxite and Solarite rods can cast into lava) | 2 | Glows. Turns into lava rock ground when it touches water |
| Acid water | Larva Hive | The Clay Caves fish (anywhere) | 60 | 3 | |
| Mold water | Mold dungeons | Mold water fish (anywhere) | 160 | 4 | |
| Shimmering water | The Shimmering Frontier | The Shimmering Frontier fish (anywhere) | 260 | 5 | Glows |
| Grimy water | The Passage | The Passage fish (anywhere) | 280 | 6 | |
| Sea water | The Sunken Sea | The Sunken Sea fish (anywhere) | 180 | 7 | Glows faint blue. The strongest: converts other water into sea water |
Water types have no name shown in the game; we use the names from the Core Keeper Wiki (Fandom). Where each one is found, the fishing value needed and "strength" (the order in which one liquid converts another when they touch; the stronger one wins) are also from the Core Keeper Wiki (CC BY-SA 3.0). We have not confirmed them in the game files.
Fish and catch chances by location are in the fishing guide, and the differences between waters in water types.
Fishing Pond Tips and Warnings
- Keep different waters apart: the stronger water converts the weaker one (sea water is the strongest). Separate them with ground.
- Keep lava away from water: when they touch, they turn into lava rock ground.
- Normal water depends on the biome: with a fishing rod, the fish are decided by the biome you are standing in. If your base is in the Undergrounds, normal water gives Underground fish.
- Lava ponds: only Galaxite and Solarite rods can cast into lava (the game's program checks for these two rods; the Galaxite rod's description says it is “Able to withstand great heat”).
Automating the Fishing Pond (Fishing Net)
Place a Fishing Net over the pond and add critters, and it catches that water's fish automatically (automatic fishing).
Item names, descriptions and the lava-rod rule are from the game files of Core Keeper 1.3.0.6. How water behaves (a bucket does not use up the source, waters convert each other, lava and water make lava rock, normal water depends on the biome) could not be checked in the game data; it is based on the Core Keeper Wiki (Fandom) pages Bucket and Water (CC BY-SA 3.0), in our own words.
Unless a note on the page says otherwise, numbers are read from the game files of Core Keeper 1.3.0.6 (prefabs, configuration files, drop tables and the game's program) and calculated by this site, including upgraded (per-level) values, sell prices and mana costs.
