I've caught one off a rig before but I have better luck on the tripletails around smaller isolated cover (i.e. floating debris, channel markers, lone pilings, etc). Grass mats offshore will hold some nice tripletails also.flappininthebreeze (3/8/2010)Ever see any tripletail (blackfish) there? Used to catch the heck out of them around channel markers. Do they get up around rigs too?
