Seems to me if they taste the same or better than the native species, who cares if the native species goes extinct?

I don't think extinction of the native shrimp is really possible. The real issue is likely an economic one: What will be the changes, if any, in the populations of tiger shrimp vs. their prey species? If they get a good foothold you can expect the native shrimp to become less common and the tiger shrimp more so. Question is, will the tonnage of all shrimp caught stay the same, or drop, or increase? And what will happen to the dollar value of that catch?

Good points yes.
