Hard to pick favorites but here goes...
Mahi Mahi aka Dorado aka Dolphin.... the best grilled fish there is IMHO...Soy sauce, garlic powder, ginger, seasame seeds, lime juice.... grilled with mesquite wood chips..on a fresh roll (toasted on the grill) with a real summer Jersey tomato and spinach....And a Summer Ale........Its SUMMER on a Bun!
Bluefin tuna, seared ...or not... with soy sauce & wasabi, cucumber...
Yellowfin Tuna...great seared on the grill...here its a side salad to a mahi sammich...with sesame ginger dressing...Italian dressing works great too. (Substitute YFT with Wahoo aka Ono whenever possible)
Enough grilling....
Breaded/Panko and DEEP FRIED!!
In order of preference:
Black Sea Bass
Tilefish
Flounder/Fluke
Cod
Striped bass
All fantastic!...with a side of deep fried peirogies
