I love Bonito! It is a small member of the Tuna family (general 10-12 lbs) with very light color flesh.
When my Dad used to have his 25' boat, we would go out of Shark River Inlet (NJ) and for about 2 weeks in Sept you could catch them. Only on days when the water was crystal clear, they would be about 30 feet down, just under the Albacore (another Tuna that was not so good to eat).
They have extremely good eyesight, we would fish with, and chum with Spearing, and you had to tie a small black hook with no leader and hook through the eyes. If it was not done right, you could watch them going through the chum, and maneuvering around your hook!
They were great fighters, challenging to catch , and taste great. The first time I caught one it was a bright sunny day, and it looked like a metal - mechanical fish!
There were also tons of Bluefish in the area, and if one grabbed your hook, w/o the leader, it would usually just cut you off.
I am not a big fish eater, but fresh Tuna, Swordfish or Artic Char are at the top of my list, then Salmon and Trout. Red Snapper and Mai Mai can also be very good. That's my 2 cents!
