Mosasaurus guide

The Mosasaurus is a prehistoric catch from Ancient Isle, and its weight is the headline. It averages 11,500 kg, starts at 5,400 kg and tops out at 40,000 kg, which ranks 65th of 663 fish with a documented maximum.

Heavy does not mean expensive. At only C$0.54 per kg, the average sale comes to C$6,000, 155th of the 742 documented fish by average value, and it gives 3,000 base XP. The payout is good, but it is the weight that holds it up, since the per-kg price is so low.

To catch one, bring Truffle Worm, fish at Night and wait for Foggy weather. In the same zone and rarity are Helicoprion, Meg's Fang and Meg's Spine, so you will be fishing among other ancient predators. The rods sold on the isle are Krampus's Rod, Phoenix Rod and Stone Rod, and any of them lets you gear up on the spot.

My recommendation is to treat this as a patient target. The conditions are narrow, but the payout depends on the weight of the roll rather than a lucky multiplier. If you are already on Ancient Isle at night with Truffle Worm, cast for it. Otherwise, compare it with the other fish of the same zone before committing a whole session.
