This massive dolphin to the right was caught out of the Tropic Star Lodge nearly 9 years ago. The crew that caught this behemoth, including Mr. Tred Barta and Mr. Dennis Braid, estimated the fish to have weighed between 115 and 120 pounds before they filleted it and fired up the grill. While we are excited this photo exists of this catch, unfortunately, the International Game Fish Association (IGFA) never received proper documentation of this fish, which would have been necessary to challenge the current all-tackle world record. Had this fish been properly weighed, measured, and documented with IGFA it is likley it would have shattered the current 87-pound world record held by Mr. Manuel Salazar caught in Costa Rica in 1976. We do wish this specimen was documented with IGFA, the world’s most widely recognized authority on the conservation of game fish and the promotion of responsible, ethical angling practices, through science, education, rule making, and record keeping. We can only wonder how old this fish was. With scales used for age determination, the maximum age of dolphinfish was estimated at four years for the Straits of Florida (n=511; Beardsley, 1967), three years off North Carolina (n=738, Rose and Hassler, 1968; n=339, Schwenke & Buckle, 2008), and three years in the Mediterranean Sea (n=150, Massutí et al., 1999). The longest time at liberty for a recapture within the DRP is 557 days, which was a fish that weighed 58 pounds and was recaptured by Captain Raudrick Nazario of San German, PR. While completely speculative, doubling the weight of Nazario’s fish would put it close to the dolphin landed 9 years ago at TSL (i.e., ~116 pounds), but how
old would that fish be? Given that, for most animals growth begins to slow with age, doubling the time at large for Narazio’s fish would equate to 3.05 years at liberty. Narazio’s fish was tagged by Captain Bouncer Smith aboard his boat Bouncer’s Dusky in 2011 as a
20” peanut (i.e., approximately 5 months old). Add the age at release to twice the time at large for Narazio’s fish and we arrive at a 3.43 year old fish at 116 pounds. This would equate to a growth rate of 1.6 ounces or 45 grams per day for the life of that fish. Growth obtained through the DRP’s tagging data suggest fish grow around ~45” or ~28 pounds (35 grams per day) in a year (unpublished). Other studies suggest 50” or 40 pounds (49 grams per day) in a year. To sustain that type of growth rate for 3 and a half years is almost inconceivable but, who knows maybe this species can pack on 100+ pounds in 3.5 years. Point being, had this beast been properly documented with IGFA, we would know more about the age and growth of this species. This is not the first time a likely hundred- pound dolphin went undocumented. Just over 3 years ago, another potential century-mark dolphin was caught off Cabo San Lucas but was filleted before being properly documented with IGFA. Because documentation is critical, we think it’s necessary to share the steps to properly document and submit a potential all-tackle world-record breaking mahi with IGFA in part I of this month’s article.
The process for documenting a potential record-setting dolphin, or any other fish, needs to be done correctly. Below is a basic list of steps to follow.
Documenting the most rare of individuals of any fish with IGFA does entail a thorough process, but we are grateful that this process exists to allow anglers the opportunity to advance society’s knowledge on the uniqueness of the rarest individuals in any given species. We just still can’t believe that 87 pounds is still the all-tackle world record for mahi! But, with large 72- to 76- pound fish caught off the U.S. East Coast just last year (and last month), maybe it could happen this year. So, get your scales ready. Examples of some acceptable weighing devices and scales which must be certified by authorized officials are shown to the right. Part II of this article examines current state- and country- based dolphin records around the country and region (see table below) and we use recapture data to examine when it is likely state records could be challenged, and that is spring. The table below will be updated periodically and expanded to contain more records for large dolphin in other key locations such as the Bahamas and Dominican Republic.
