PORT ARTHUR —
Garrett noted that avoidance behavior as well as the ability to discern
natural prey from artificial replicas likely would be best developed in those not harvested (fish caught and released to breed again.)
“Selective pressure, however, will influence future generations only if a trait is heritable. If angling vulnerability has a genetic component and there is genetic variation in the trait, succeeding generations would be made up of a greater proportion of those less susceptible to angling.”
Isn’t it ironic that we imported Florida bass to increase the quality of our fishery and yet it has probably made bass fishing more difficult?
It would be difficult to argue the introduction was a mistake because it has done such great things for the size of our fish. I for one am glad TPWD did this so many years ago.
It is interesting to note that science backs up the assertions of so many anglers who have long said fishing pressure even in what is chiefly a catch and release fishery has a dramatic impact on how the fish bite.
Technology is giving us a more intimate look at fish and wildlife than we ever thought possible. It will be exciting to see what they uncover about largemouth bass in the future.
