I still see whites, striper, and hybrid surface activity although I will agree and say it is not what it once was - I have attributed that as much to boat traffic as anything. I do not keep many whites but I don’t recall seeing many “mutts” as you call them and I catch hundreds a year from the Gravi and lower end; but that last photo IS interesting - you sure you didn’t pick that fish up after it has been floating for a day or so? 😉 I will say this, I will be looking more closely at the whites I catch this year and rest assured that I am doing my part as ❤️ me some hybrids and harvest and eat a good number every year from the Gravi.
Those stripers should be in the 22” range this year and will be more fun to catch but I intend to continue letting them grow to adult gizzard eating size before I put any in my freezer.
