Blue Marlin are one of the largest of the billfish we have in the Cabo area, tied possibly by its relative the Black Marlin. They are a warm to temperate water fish, preferring temperatures from 82-88 degrees but sometimes appearing with water as cool as 74 degrees. They mainly feed on other fish but are known to feed on squid as well. I have hooked three Blues of over 1,000 pounds while living in Guam, but have not seen that size myself here, although other anglers have reported hooking fish of that size. To the best of my knowledge no Blue Marlin of over 1,000 pounds has been boated in Cabo San Lucas although at least one fish has come very close. Longline records from Japanese fishermen have shown that these fish can weigh up to 2,000 pounds, but the largest on rod and reel was 1,805 pounds, caught in Hawaii. The males top out at right around 300 pounds, fish over this size are females. Trolling lures is the most productive method of fishing for Blue Marlin, and concentrating on areas where there are Skipjack Tuna or Yellowfin Tuna, such as high spots, ridges and drop-offs and current lines seem to produce more fish than fishing open water, but the larger specimens seem to prefer the open ocean far from land. The Bisbee Black and Blue Fishing Tournament held the third week of October here in Cabo San Lucas is the richest sportfishing tournament in the world, and only Blue and Black Marlin over 300 pounds count. One year a boat took home over 3 million dollars for winning the tournament. Last year, 2014, I was on the team that came in with the second place fish weighing 317 pounds, but since we were in all the jackpots we took the most money, a cool 1,600,000 dollars. The average fish caught in Cabo is between 200 and 300 pounds and they are almost always caught in the summer months when the water temperature is over 82 degrees. Large Striped Marlin are sometimes confused with Blue Marlin, but one of the best ways to tell the difference is to look at the dorsal and pectoral fins. On a Striped Marlin the dorsal fin almost always looks as if the top inch has been cliped off and the pectorals look more like paddles, on the Blue Marlin the dorsal has a sharp point and the pectorals are much slimmer and come to a sharp point.
