Orca

Orca is an Exotic fish from The Ocean, and the wiki tags it as a Hunt fish, which means it is a deliberate target. It takes Shark Head bait, and no weather, season or time restriction is listed. The in-game note is short: orcas tend to migrate from time to time.

It averages 1,300 kg with a range of 1,000 to 3,420 kg, ranking 122nd of 663 fish by maximum weight. At C$8 per kg an average catch is worth C$10,400, 121st of the 742 documented fish, with 900 base XP. That puts it in the top fifth for value and well above the typical Ocean catch.

In the same zone the Exotic tier also includes Blue Whale and Blobfish, so those are the other Exotic fish to expect when you are using heavy bait out there.

Verdict: a good target when you want a reliable big payout without waiting for a specific storm or night. With no weather or hour conditions, the only real investment is Shark Head and a rod that can handle more than a tonne. It will not match the biggest Apex fish, but for a single bait and an open schedule, C$10,400 per catch is among the better deals in The Ocean. Fish it when you have the supplies and sell the extras.
