Summary of Large Shortfin Makos Isurus oxyrinchus

About 80 Specimens are sorted according to total length (TL). If only mass was available, TL was estimated from the most appropriate mass-length equation. Order according to mass would be different because shortfin mako from the western North Atlantic are on average about 15-20% heavier than those from Southern Hemisphere (Mollet et al. 2000) .
p.c. = personal communication.

* estimated from PCL or FL using equations given by Casey and Kohler (1990) and Cliff et al. (1990) .
** estimated from W (kg) = 7.658* TL^3.10 (m) for Southern Hemisphere (Stevens, 1983; converted to m); W (kg) = 7.299 TL^3.224 (m) for western North Atlantic (Mollet et al. 2000).

The shortfin mako was seen on 3 Sep 2005 at 9:20 a.m.; position 36.37570 N and 121.52596 W; water - 142 feet deep (43 m) ; water temp 15.5 Celsius; in Monterey Bay. Identified by Dave Ebert and Bob Lea from photo in first column. Photo of dorsal fin confirmed ID. Capt. Richard Ternullo [co-researcher with Peggy on killer whale project] estimated the shark to be 8 to 9 feet long.
Location is about 2.5 km off Del Monte Beach, Monterey and New Monterey/Cannery Row, Monterey. Can be considered outer Monterey Harbor. The shark was eating a harbor seal, Phoca vitulina, Family Phocidae, Order Pinnipedia. Richard, a biologist, has been a sea captain for 30 years running natural history, birding and whale watch trips. He told Peggy that in all the years on the water this was the first time he had ever seen anything like that (i.e. a mako eating a harbor seal). Thanks to Peggy Stap for information.

Subject: RE: Shark question
Hi. It took about 45 minutes to get the shark to the stern. In hindsite it was too fast - as we were using 200 lb. test (braided line). It was pandemonium getting the ropes on it but it didn't tow the boat. We got two small head straps on it first, and tied them off. Seconds after we got a larger rope around her midsection, she broke both head ropes and the leader all at the same time. Then we got a rope around the tail. It was an open stern with the sissy bar removed when the shark came to the stern. The captain lifted about five feet of it out of the water with the boom, and didn't dare lift it any farther. We put another rope around the midsection and the four of us pulled the rest ot it aboard. (abbreviated). Terry.
Data from Steve Campana: FL (over the curve) was 330 cm, TL was 342, IDL was 92, whole wt was 492 kg and dressed weight was 381 kg. Vertebrae were collected and aged.

A 1,063-pound mako shark hooked close to shore in the Gulf of Mexico isbeing investigated as a possible world fishing record. The registered weight of 1,063 pounds makes the catch eligible for the world record in the 30-pound line class for a short-fin mako. The class record is a 997-pound, 11-ounce shark caught in Sidney, Australia, in 1995. The largest mako recorded in the all-tackle division was a 1,221 pounder caught in Massachusetts in 2001.

OXNARD, Calif. -- A Newbury Park man has reeled in what could be the largest fish ever caught off the coast of California. Sean Carlsen Gizatullin was taking part in a fishing tournament off the coast of Oxnard when he caught a Shortfin Mako Shark weighing in at 1,098 pounds."It went under the boat a few times, came out twice with its jaws open towards the boat," Gizatullin said."It didn't lunge out or anything crazy like Jaws but it was still intense."Gizatullin says it took him so long to reel in the giant fish that he was 45 minutes late for the weigh-in and did not win the tournament. Pending verification, the shark is the largest fish of any kind ever caught off the coast of California.

2nd largest one as per July 2010. Largest one weighed 533 kg (1175 lbs) (see below)

When Chris Podesto hooked into a huge shortfin mako shark off Catalina Island he watched in awe as the powerful gamefish ran and jumped wildly like nothing he's ever seen in his life. The 13-foot mako was leaping 30 feet in the air and making 300-yard surges, towing a 27-foot fishing boat around like a toy.

Douglas J. Long Male
4.02 >454 kg (>1000 lbs) dressed weight   From Douglas Long:
I've been collecting known-length shortfin mako jaws for a study on dental ontogeny & diet, and I just received the biggest specimen yet, a 402 cm (13' 2.3') TL male from off SW Australia (5 km off Augusta, Western Australia, caught at 17 fm)s. Accurately measured & recorded dockside by someone I trust (Joseph "Shark Doctor" Legende out of Perth), even had a chunk of pilot whale in it's belly. Said to be the largest yet taken off Western Australia, but 'official' records aren't kept for commercial catches the way they are for game fishing, except in the occasional academic literature.
Sex was confirmed by captain and first mate who dressed it out: "It was a he-fish. Real long and skinny, a big and battered Ole Geezer. Looked old as the hills. Real thin tooth for It's size." The captain's son (in his mid-twenties) confirmed that it was a male. They remember because of the whale meat in its gut, so unusual that it helped them to remember this grand ole fish.
  Gordon Hubbell p.c. Fem? >4.27     Over the years Gordon Hubbell has imported at least 25 jaws from makos of more than 12' in length. In fact the largest jaw, which has an obvious shortfin mako dentition, is probably from a shark of at least 14' TL. I have this jaw in my collection. So I have no doubt that shortfin makos reach this size and longfin makos probably slightly larger.
Kabasakal & De Maddalena (2011) Fem ~5.8-6.2   PCL 4.86 PDF of paper can be downloaded in Reference columns.
Abstract: A huge female shortfin mako shark, Isurus oxyrinchus, was caught in the late 1950s off Marmaris (SE Aegean Sea, Turkey), by a commerical fisherman. Photographic documentation has been used by the authors to estimated the total length of this specimen at 585 cm (range from 577 to 619 cm). This size greatly exceeds the maximum size recorded for the species (a 445 cm long female caught in September 1973 off Six-Foures, les-Plages, France). It is believed that the Marmaris specimen is the largest shortfin mako ever recorded.
