Most powerful fish pound for pound.

[Sean]

Tuna tops the list.
Blue fish are also up there, pound for pound a blue fish is 3x as strong as any striper. imagine a 4olb blue fish :o
Unforunetly all of your heavy hitters, exspecially the tuna, have a very low mortality rate after being caught. They literly fight to the end, and once released have no energy to revive them selves.
