Blue tail on Redfish?

[3FLa]

A very old friend, with no formal education, but more common sense then most, always said that the blue tail has a relationship to tidal changes, which will cause an increase in bite activity. This gentleman was a commercial fisherman for many years, and would always say, "that the asses in Washington are going to tell me when I can catch shrimp, and not one of them ever seen a live shrimp." Like I said, not much fromal education, but full of wisdom.
