The Moga is one of the harder fish to catch on Realism Mode.
The Moga never tires and never sleeps. It is incredibly strong and can easily snap a weak line. Accustomed to life in the dark depths, it is terrified of Lightbulbs.
Can be sold for $180,000.
In order to catch the Moga, the player will need to obtain a Huge Hook, with Tier 3 bait. Although the Moga is found very deep down in the ocean, it will flee from a player's line that has a lightbulb active. Sonar can be used to tell the fish's location in the place of a lightbulb.
Note: in Realism Mode, the Moga will need to be caught during the night or during a storm to accommodate for its fear of light.
The Moga will follow the boat until it passes the coral reef. Using this knowledge, a player can estimate where the Moga will be at any given time.
The Moga resembles a Sunfish.
