Funny you should say. Several of the fish I have caught this year in Greasy I have said to my self and mentioned to others. "man, that looks sort of like a hybrid.
Stripers are elongated/torpedo shaped and these were very deep (from belly to dorsal fin). They didn't have the smaller "face" if you know what I mean. Maybe it's just the extra weight they have put on which is quite a bit. They just looked taller.
Maybe they are of "wack" from being on death watch for a few years. Caught quite a few that were paper thin in the last years...like maybe less that 4 pounds at 24". Now it's more like 6 pounds at 24".
