๐ Core Keeper โ Fishing Guide & Fish Database
Your complete reference for fishing in Core Keeper 1.0 โ from unlocking your first rod to catching every legendary fish.
๐ฃ How Fishing Works
๐ ๏ธ Unlocking Fishing
- Defeat Glurch or Ghom (first two bosses)
- Collect Fibre from grass plants
- Craft a Basic Fishing Rod at the Workbench (8 Fibre + 6 Wood)
- Find any water pool โ press and hold left-click to cast, release when the bobber splashes!
๐ Fishing Skill
- Level up by catching fish
- Higher level = better catch quality + rare fish chances
- Skill rewards: faster casting, less reel time, rare fish detection
โฐ Time & Location
- Fishing takes real time โ no day/night cycle
- Different biomes = different fish pools
- Deeper/larger water pools = better fish
- Fish Traps (crafted later) provide passive fish income

Placement Tips
- Deep water produces better fish than shallow puddles
- Large water bodies attract rarer fish
- Place traps away from each other (cannibalize catch rates)
- Check traps every 20-30 minutes โ they stop catching when full
- The Sunken Sea has the best trap ROI

๐ก Pro Tips
- Upgrade your rod first โ a better rod pays for itself in rare fish
- Cook your fish โ many fish are worth 2-3x more as cooked dishes
- Fish traps are OP โ 5 traps generate more gold than most crops
- The Sunken Sea is the best fishing zone โ highest value fish + Glow Tuna for breathing buff
- Legendary fish require high fishing skill + upgraded rod โ save them for the museum!
- Sell duplicates โ you only need one of each fish for museum/achievement
- Fish during exploration โ every biome has unique fish, so fish as you explore
