Waller's Table 4 reprints Block et al. 1992: a blue marlin burst of 4.9 mph (2.2 m/s) for 5 seconds, descending, at 60 m.
A blue marlin can swim 4.9 mph (2.2 m/s), a verified measurement.

Waller et al. 2023, Table 4. Blue marlin, Makaira nigricans, towed speedometer, length 5.9 feet (1.8 m), sustained 1.1 mph to 2.2 mph (0.5–1.0 m/s), burst 4.9 mph (2.2 m/s), duration 5 s, depth 60 m, descending. Reference Block et al. 1992. The figure is 4.9 mph (2.2 m/s).
In context
Worked out from the sourced figure above, which stays the ranked number.
Quick answers
A blue marlin can swim 4.9 mph (2.2 m/s), a verified measurement.
Blue marlin is labeled Verified. Independently measured and published, for example in a peer-reviewed study or with certified timing.
The figure cites Journal of Fish Biology, “Blue marlin burst in the large-pelagic speed table.”
Blue marlin is 9th of 10 on Fastest Fish & Sharks.
Mechanism
Waller's Table 4 reprints Block and colleagues 1992: a blue marlin, Makaira nigricans, burst of about 4.9 mph (2.2 m/s) for 5 seconds, descending, at 60 meters depth.
The 4.9 mph (2.2 m/s) burst lasted 5 seconds while the marlin was descending at 60 meters. A descent is not a horizontal sprint. The comparison keeps those conditions. Svendsen's sailfish estimate of 18.6 mph (8.3 m/s) is a different method and a different fish.
Block's 1992 speedometer reading is what Waller reprints. The page does not update it with a later angling claim. Five seconds is the duration, not a distance.
Provenance
Claimed, measured and official figures side by side, each with its source. The ranked figure is marked.
Waller et al. 2023, Table 4. Blue marlin, Makaira nigricans, towed speedometer, length 5.9 feet (1.8 m), sustained 1.1 mph to 2.2 mph (0.5–1.0 m/s), burst 4.9 mph (2.2 m/s), duration 5 s, depth 60 m, descending. Reference Block et al. 1992. The figure is 4.9 mph (2.2 m/s).
The 5-second duration and the 1.1 mph to 2.2 mph (0.5–1.0 m/s) sustained band stay beside the main figure. What counts is 4.9 mph (2.2 m/s).
Reference
Context
Waller's Table 4 reprints Block and colleagues 1992 for a blue marlin: length 5.9 feet (1.8 m), a towed speedometer, sustained 1.1 mph to 2.2 mph (0.5–1.0 m/s), and a burst of 4.9 mph (2.2 m/s) for 5 seconds while descending at 60 m. The figure is 4.9 mph (2.2 m/s), qualifier verified.
The sustained band and the 5-second duration are notes, not extra ranks. Older estimates near 78.3 mph (35 m/s) are not this trial.
