Saltwater fish, yep big baits big fish. I'll never argue with that.
Salt fish dont have the food availabilty in such large numbers like dam fish either, so often whatevers there is going to be eaten.
Those salt fish have to do a lot of work in current, have to escape other predators and survive in big tidal ranges which in turn assists the digestion process. They have evolved that way.
Dam fish do not need to have the tail in motion 24/7 like a wild fish does, hence the fighting supremacy and endurance salties hold over dam fish.
Dam fish are evolving down a different path, and have found optimum feeding/survival patterns to create an easy lifestyle that sees them triple the growth rate of their wild cousins.
That is why the are growing so big, lots of food, minimal effort.
Theres a clear difference between the two fish.
