I would agree. You will see bay trout follow the food source throughout the seasons but I don't think there is a ton of exchange between gulf trout and bay trout.
I follow a couple of jetty guides on FB and I noticed that not one of them has posted a pic of their catch that included in a trout in many months. I don't know where the Gulf Trout go during this time of year but it is not the jetties. I text one and asked him when he will start to see good trout show up and he said "mid to late April".
I did sign up for Trout Support's Members area last year. I found it really informative in regards to the seasonality of Trout, Reds and Flounder. Tobin has a really strong background in Ecology and does videos every week talking about what to look for when on the water. So if you are looking to geek out on saltwater fishing info, I think it is worth it. If you fish Galveston area, he has a Reef Recon overlay for your GPS that is pretty nice. There is a forum set up where members share ideas, product info and Tobin has been very good about answering questions that are posted.
I think on Sunday I am going to tear down all my fishing gear and reorganize. And I need to switch out some hooks on lures.
Troph - There are two fishing websites that I follow. 2Coolfishing.com and then there was a rebellion last year and these guys started dosfrio.com offshoot of 2 Cool. On one of those websites is a guy named Shark Chum who apparently is the Mr Miyagi of surf fishing. Definitely looking for his posts for tips.
