  1. 1. BLUE MARLIN By Shon Wiles
  2. 2. TAXONOMICAL INFO Kingdom  Family • Animalia • Istiophoridae Phylum  Genus • Chordata • Makaira Class  Species • Actinopterygii • Makaira nigricans Order • Perciformes
  3. 3. PHYSICAL APPEARANCE Belly: silvery white Top: Cobalt Blue Upper Jaw: Elongated Spear Tail: Cresent-shaped Dorsal/Anal Fins: Pointed Lateral Line: Interwoven Max Length – Male: 368 cm. Max Length – Female: 626 cm.
  4. 4. LIFE FACTS Rapid growth for a few years. Age 2 (males) and Age 4 (females) - sexual maturity Highly fertile – 500K to 55M eggs per spawn • Age • Weight Estimated maximum age is greater than 20 Seafood Watch - cite
  5. 5. REPRODUCTION Female releases eggs, Male releases sperm • Fertilization happens in open water Eggs float with the current Eggs hatch into larvae • two days after fertilization No parental care • High mortality
  6. 6. FEEDING Hunt during the daytime • Alone • Use of bill (slice/stun) Prey • Octopi • Squid • Blackfin Tuna • Frigate Mackeral
  7. 7. CONSERVATION Decreasing Population • High vulnerability of extinction from fishing Low survival rate when released • Required billfish release if within 200 miles of U.S. coastline Longline Fishing • Caribbean Region • Over 1k tons taken by Japanese and Cuban fisherman
  8. 8. THREATS Longline Fisheries  Parasites • 73% incidental landings • Digenea (flukes) Swordfish Fisheries • Didymozoidea (tissue fluke) • By-catch • Monogenea (gillworms) Big Game Recreational Fishing • Cestoda (tapeworms) • Nematoda (roundworms) Predators • Acantheocephia (spiny- • Carcharodon carcharias head worms) (white shark) • Copepods • Isurus oxyrhinchus (shortfin mako) • Barnacles
  9. 9. FAST FACTS Highly Migratory Largest Pacific • 1,376 lb. May 31, 1982 • Kaaiwai Point, Kona Largest Atlantic • 1,402 lb 2 oz. Feb 29, 1992 • Vitoria, Brazil Rumored 3,000 lb get-away Most fish over 300 lb - female
