Thanks Rebecca, I think I missed the part in the report about them meeting up in the passes to spawn. That does answer my question about genetics. Padre Island is the longest barrier island in the world with very few passes between Packery and South Padre. The surf trout must travel a long way to meet up with bay and laguna trout to spawn. No wonder they fight so hard. Tough fish.

I'll just keep on trying for that really big one in the surf.

There are definitely differences between the Laguna and surf trout (skinnier, more spots, darker overall coloration) but they can still reproduce with each other therefore the same species. Think about the differences among dog breeds, if you had no concept of dogs and saw a chihuahua and a great dane you would never guess them to be the same species. Now in the future they may diverge enough in geography, behavior or anatomy that it prevents successful reproduction between the populations and speciation would occur.

greenhornet2, I think you may mean genus and not species. Fish would be the genus, species would be the trout, and subspecies would be the type of trout. Blue marlin are in the genus fish, but can only reproduce with their species and really only with their particular subspecies ie: blue marlin.

I hope I never see a blue marlin with a shark head.

I had to google this because I was confused and I had forgotten about the genus category.
