FishMon is an app in Dave the Diver.
Unlike other apps, which are unlocked after particular missions or reaching a particular chapter, this one is based on other factors, such as number of photos taken. As such, some may have this unlock while still in Chapter 3, while others may not get it until near the end of the game.
That said, after a certain point, Udo will reach out with a new work assignment he has and needs Dave's help with: to capture novel fish, but alive. The assignments will come in on the weekends and need to be completed by Sunday evening in time for the Monday publication. He'll also give you the Fish Tracker, which will notify you as you get close to target fish but also lets you view all the fish you've caught and their ranks while underwater.

Tips[]
- If you fail at successfully capturing the novel fish, you'll have to resurface to try again. The location may be slightly different, however.
- It's important to not kill the novel fish. Udo will typically note on screen when the target is unconscious so you don't accidentally harm it further.
- Most FishMon can be captured with a Steel Net Gun, even if the game suggests a specific damage type.
- Make sure you have at least 20kg free space in your inventory to carry the Silver Titan Triggerfish.
- The Spotted Moray Eel is a night time fish and has an AoE attack that it'll try to catch you in. It cannot be put to sleep by the Modified Hush Dart.
- The Ice Stingray is impervious to all forms of damage except fire.
