The Big One Fish Lock Routine: Decide What to Sell and What to Keep
The Big One is a casual fishing RPG built around casting, waiting, hooking, reeling, equipment progression, 150+ fish species, 10 fishing locations, and Fishpedia collection. Once your Net starts filling up, a quick split between fish to sell and fish to keep makes the next cast smoother.
The point is not to keep every catch. Keep only the fish that deserve one more look: a new Fishpedia record, a cooking candidate, or a target catch. Turn the rest into Gold for the next equipment or location goal.
When to keep a fish locked
After a catch, four simple questions are enough. Use visible player goals rather than hidden numbers.
A Net is both storage and fewer interruptions
Better Nets let you sort catches less often. Pairing that with a lock routine helps protect rare catches and cooking candidates before using Sell All.

Decision table
| Situation | First move | Why |
|---|---|---|
| It may be a new Fishpedia record | Lock it, then check Fishpedia | You can decide later whether to sell or cook it. |
| It looks useful for cooking | Lock before selling | Locked fish are protected from Sell All and cooking consumption. |
| It is common and your goal is Gold | Leave it unlocked and sell | That keeps progress moving toward rods, bait, or Nets. |
| Your Net is almost full | Sell everything except locked fish | Sorting stays short, and you can return to the fishing location fast. |
