Sei Whale
“The third-largest rorqual in the world, known as an offshore speed demon capable of sprinting near the surface at immense speeds. Distinctive for its sleek steel-gray body and single head ridge, it relentlessly pursues dense shoals of krill across temperate open waters.”— in-game Bestiary description

Sei Whale guide
A base XP of 40,000 is the headline figure for the Sei Whale, an Exotic fish documented in The Ocean. Its weight range is just as large: a minimum of 12,000 kg, an average of 36,000 kg and a maximum of 60,000 kg, which ranks 74th of 1,059 fish by maximum weight.
The price is only C$0.583 per kilogram, yet the mass carries the value to a listed average sale of C$21,000, ranking 92nd of 1,038. The wiki calls it "an offshore speed demon" and notes its sleek steel-gray body and single head ridge. Krill is the listed bait, with Night, Windy weather and Summer as the conditions.
The Ocean has 65 documented fish, and five other Exotic fish are listed there: Blue Whale, Blobfish, Fin Whale, Humpback Whale and Orca. Verdict: a top-100 fish by both maximum weight and average value, so it is worth planning for Krill and a Night, Windy, Summer window.
