Bruce, the funny thing is that the bait shops down at Galveston now sell tilapia right next to flounder, shrimp, and other edible fish. The saltwater redfish & trout records will obviously fall due to tilapia as forage, and when there's a hard freeze that kills the predators (redfish & trout), the tilapia will have been toast days prior to the demise of the predators.
I sure would like to see someone post a counterpoint, it doesn't make sense to me.
