Magma-Glass Marlin guide
Weight does the work for Magma-Glass Marlin: the wiki lists 160.0 kg at minimum, 290.0 kg on average and 420.0 kg at maximum, which ranks 241st of 1,059 documented fish. The price per kg is only C$7.867, yet the average value still comes to C$2,281, with 2,100 base XP.
Rarity is Legendary and the fish is documented in Obsidian Trench with Squid as bait, by day, in clear weather and in summer. It is listed as obtainable. The quote describes "A lightning-fast pelagic billfish with a long, translucent bill formed from naturally fused volcanic glass."
Value ranks 348th of 1,038, lower than the weight rank, which fits a heavy fish sold at a small per-kg rate. Obsidian Trench documents 11 fish, and the other Legendary entries there are Basalt Behemoth and Shatter-Tooth Shark.
Verdict: a big fish in the top quarter by weight, whose value comes from sheer mass rather than a high per-kg price.
