Thanks jolly. was watching a fishing program today. It show how in florida in the fall they have a major mullet and shrimp run. The mullets are spawning and the shrimp are moving out of the marshes into the gulf. they showed how the run could last for a month or just a few days. But the fishing at that time is amazing. But I have seen the water black with mullet here in the fall, and Ive also caught a lot of large shad in the fall with throw nets.
