And, I do understand you opinion.

Nature does balance, but that balance may destroy many native species. This story didn't go into the details so I am not sure, but if the 13 inch shrimp takes over the native shrimps I think of a couple of problems.

What about the species which may eat the native shrimp but can't eat the Asian Tiger Shrimp? Will that species start to feed on another species thus interrupting another food chain. Will species which depend on the native shrimp also die? What about the animal that eats that species. Sometimes the extinction of one species is just that, one species, but other times it takes a couple of other with it. Some food chains are very strong, others are rather weak. If it happens by an act of nature well enough, but when it is an introduced species we need to take the "you break it you bought it" policy, never the less the balance may take a long time and redistribute the populations through out an entire ecosystem.

The story just touched on this but there is a shrimping industry which has been effected by the BP oil spill. I can see how the Asian Tiger Shrimp my help some but if it means the extinction of the native species I see more harm than good. Currently, restaurants purchase75/100, 50/75, 20/25, 10/20 and U/10 to name a few I can't see U/1 being the only option a good thing.

I wish lemon and butter was the answer and I agree at least this is an editable species unlike carp, piranha and others. This may not be a disaster, and in the aftermath of the BP oil spill it may even be good.

My real point was a carefree attitude toward the possible upheaval of an entire ecosystem, without taking anything else in consideration. This may not be fair but I could imagine those posters also stating that climate change bogus.
