In the waters around Chatham, I'm tempted to say that little has changed since last week, but that is the easiest report to fall aback upon. Here's the rundown, and some of the subtleties.
First of all, there is God's own amount of bluefish around Chatham, especially to the west of Monomoy. The fish here have been on the surface, virtually all day from what I have witnessed. The blues are feeding on sand eels, and most recently, tiny one-inch bunker, which have spilled out into Nantucket sound all the way out to the end of Monomoy. In addition, there are some very large choppers INSIDE Stage Harbor where they are hanging around several schools of adult bunker. These fish are catchable all day long, and are great sport. Look for them in the cut, and just inside.
There are still some bass in Bearse's rips, but slower tides, and mid-day floods have made
for much slower fly fishing. Bass are still visible on the bottom under the first wave, but they are more difficult to catch, and stay low in the water column. I have caught some bass along the beach at the end of Monomoy while looking for bonito.
There are pretty many tuna east of Chatham, but the fish are 18 to 20 miles out – at least that is where the whales and shearwaters are concentrated. There is virtually nobody fly fishing for the bluefin, or even using light tackle. Everyone is trolling using squid bars and heavy tackle. Most of the fish look to be around forty pounds, but there are some bigger fish reported too.
I have seen absolutely no bonito, even with all the baby bunker around, and am tempted to say it is not possible to catch them on purpose.
