I fished Rosebury Friday longlining, and like you I caught 4 really quick but then never caught another one. I talked to two other boats and they had never even gotten a bite. One guy had fished 5 days most of the day each day and only had a couple fish each day. Some fish are being caught there in shallow water I think on minnows, but it is hit or miss, they might catch a lot one day and then not catch much for a trip or two. I have had some pretty good days lately, and then some pretty slow days.
