I am very far from an expert on such a topic, and am looking forward to exploring the next couple of weeks to try to come up with a theory... but so far, I found slightly smaller fish, in all the same places as they have been for most of the summer. I have heard that the mackeral are back at the mouth, which seems like a good sign. Also the 70 degree water taht we enjoyed during august to cool us off was down to 56 degrees on teh same tides last weekend. So, I would guess that is a trigger, which makes me think that whatever is about to happen is probably going to start happening soon. :)
