Fishing with Capt. Anthony Mendillo of Keen M International out of Isla Mujeres, Jessica Harvey, 22, daughter of marine artist and conservationist Guy Harvey, landed an enormous swordfish estimated to weigh more than 600 pounds. The fish qualifies as an Isla record and is also thought to be one of the largest caught on rod and reel by a female angler in the last 30 years, according to Harvey's publicist.
