The White Marlin (Kajikia albidus) was named "Osprey" (GFR10805), was caught by angler Junior Doerzbach while fishing the mid-Atlantic offshore waters of Maryland on, September 9th, 2016. Junior Doerzbach was fishing aboard the charter boat Rhonda's Osprey with Captain Joe Drosey and mate Sasha Lickle, out of the Official Research Center, Sunset Marina & Atlantic Tackle (http://ocsunsetmarina.com/) located in Ocean City, Maryland, USA. The White Marlin was estimated at 65 inches (165.1 cm) total length and released in excellent condition.

The recapture was approximately 1.6 miles (2.57 km) away from the original tag location. During that 24-hour time period, the marlin stayed in the mid-Atlantic offshore waters of Maryland. Those offshore waters are home to numerous seafloor canyons which ideal habitat with an abundance of prey items, such as mullet, menhaden, jacks and common bait fish species.

At the time of recapture, the White Marlin had a measured total length of 79 inches (200 cm). Based on the length measurements, the marlin was a mature fish. After the tag information was recorded, the White Marlin was released healthy and unharmed.

White Marlin (Kajikia albida) are a pelagic billfish species occurring in only in the Atlantic Ocean. They are a midsized smaller billfish species that is characterized by a long, compressed body shape with dark blue coloration on the upper side and silvery white below. A noticeable feature is the first dorsal fin, which runs almost the entire length of the body. The maximum recorded length for White Marlin is 110 in (280 cm) but they are commonly found at a length of 51-83 inches. Like many other fish species, White Marlin are sexually dimorphic with the females being larger. They are commonly associated with weed lines, upwelling, and regions with bottom features such as shoals, drop-offs, and canyons. White Marlin are usually found alone or in a pair, and limited schooling may occur based on size or time of year.

Identification Information: White Marlin are commonly misidentified at Roundscale Spearfish (Tetrapturus georgii). The two fish species are similar in appearance but they are genetically different. The two species also be identified via external examination. White Marlin scales are more rigid and rounded on the posterior region of scale, while Roundscale Spearfish scales are broad and round at the anterior end. Also, if the distance between the anal opening and first anal fish is less than 50% of the height of the anal fin, it is a White Marlin.

Fun Fact: While swimming, White Marlin commonly display a technique known at "tailing", in which only the dorsal lobe of the caudal fin (tail fin) is visible above the surface of the water.

The Gray FishTag Research program has been able to shatter the expectations for fish recapture rates thanks to the hard-working professional fishermen on the water day in and day out. Tags are provided free-of-charge to the collaborating professional fishermen, and the tag data is available to the public at www.GrayFishTagResearch.org

The Rhonda's Osprey charter boat crew will receive Gray FishTag gear for their tagging efforts. The tag recovery angler, Ross Clubb, will receive a pair of Costa Del Mar sunglasses, a Tag & Recovery Certificate, and Gray FishTag gear for reporting the tag recovery.

The tagging and research efforts is made possible by our research centers and sponsors AFTCO, AA Video, American Fishing Wire, FECOP, Mold Craft, Costa Del Mar, CR Primo Fishing Tackle, Shadow Graphics, AquaWorld, Crocodile Bay Resort, Grande Alaska Lodge, Los Sueños Resort & Marina, Marina Pez Vela, Sunset Marina, The Pisces Group and The Zancudo Lodge.
