Isonade guide
Isonade is a Mythical built around a legend. Its description calls it a sinister creature assumed extinct, and it lives at the Strange Whirlpool. The only condition listed is Truffle Worm bait, with no hour, weather or season restrictions, which makes it less fussy than its rarity suggests.
It is large: weights run from 600 kg to 4,036 kg with a 1,200 kg average, and the max ranks 117th of 663. At C$6.15 per kg, an average catch sells for C$4,560, ranking 188th of 742 documented fish. Base XP is 1,200, solid but behind several Mythical fish documented elsewhere.
No other fish of the same rarity is listed for the whirlpool and no rods are sold there, so everything depends on you bringing the right bait. My read from the numbers: Isonade is a good value target if you already have Truffle Worm in stock, but it is the weight and the odd location that make it memorable, not the price or the XP.
