A Tuna Grand Slam involves a single angler catching three of the IGFA-approved tuna species in a 24-hour period.
The tuna species that qualify for inclusion in the International Game Fish Association’s Tuna Grand Slam Club are
- Bigeye Tuna
- Blackfin Tuna
- Bluefin Tuna
- Dogtooth Tuna
- Longtail Tuna
- Skipjack Tuna
- Southern Bluefin Tuna
- Yellowfin Tuna
As with all International game fish association grand slams, the fish must be caught and registered in line with IGFA regulations.
Historical Tuna Grand Slams
There have only been nine recorded tuna slams in history lodged with the International Game Fish Association.
Most of these have been caught in the US, with one in Guadalupe and one in Mexico.
Anglers William Evans, Gregg Lewis, and Thomas Paolino have each recorded two tuna slams!
William’s slams both involved a skipjack, yellowfin, and blackfin tuna and were both taken in 1999 in Texas.
Gregg’s were taken more recently in 2022 and 2023. The first involved a blackfin, yellowfin, and bigeye tuna, and the second one a blackfin, skipjack, and yellowfin tuna.
There have been no recorded tuna super grand slam entries (four tuna species in a single day) and, of course, no fantasy slam (five species in a single day) for tuna either.
