Asian Hmong Bob, sometimes I used them as streamers.
Lings are pretty cool, lots of power, attitude, very stubborn. They can get big, 60 pounds or so and must be subdued before bringing it on deck. If you just pull them on the boat, the first thing it does is vomit a couple gallons of squids, octopuses, snappers and assorted whatnots. Then it will go after whomever is closest, I swear there is true hatred in those eyes. My stupid BIL had an active 45 pounder lock on to his ankle, it commenced to thrash about while gnawin' on Chuck. I watched his two equally stupid friends beat on the fish and Chuck. After several minutes of chinese cluster ####, they manged to sever the great muscles of the lower jaw. Chuck got 21 stitches, a nasty infection and three weeks in a cast, seems that the fish worried some of the bones loose.
I release without boating any Ling over 25 pounds or less than 15. the big old predators are not good to eat. My biggest deal was landing a 25 pounder off the rocks.
