Kayaker has close encounter with mako shark off Perth, WA

Grant Bond got a little more than he bargained for off of Perth, Western Australia earlier this year. Bond was fishing from his kayak when a shark decided to get up close and personal with him. He thought at the time of the encounter that it was a white shark (Carcharodon carcharias) giving his kayak a workout, but after reviewing the footage he was able to identify the species as a shortfin mako (Isurus oxyrinchus).

When Bond first encountered the mako, it was circling his kayak, and after about five minutes he thought the shark had left the area. It was at this point that the shark, estimated at 3m in length, starting bumping the kayak. Rather than playing a game of bumper-boats with the shark, Bond decided to call it a day and head back to shore. Bond believes that the shark was attracted to his kayak by some herring in the foot well. He threw the herring as far from the kayak as he could, cut his anchor line, and headed in under sail.

Bond went on to point out that even though the mako nudged and rubbed up against his kayak multiple times, it never bit the vessel. He said the old adage about the worst day of fishing being better than the best day of work turned out not to be true, after all. Thanks to Grant for sharing this video!

Note: There was a typo in the date on the video, which was shot on March 10.

Research reveals decline in Pacific shark species

According to the Sacramento Bee, a journal article published in the latest issue of Conservation Biology reveals “significant declines in catch rates” for blue (Prionace glauca), mako (Isurus oxyrinchus), and oceanic whitetip (Carcharhinus longimanus) sharks in North Pacific waters. According to the article, the declines in catch rates indicate heavy fishing of the species. The research also showed a decrease in the average sizes of both oceanic whitetip and silky (Carcharhinus falciformis) sharks.

Video: mako shark struck by boat returns the favor

WARNING Video contains language that some might find offensive.

YouTube user ozfishwa posted the video above which documents a large shortfin mako (Isurus oxyrinchus) having a few goes at a fishing boat. According to the video description, the shark had been accidentally struck by Damo & Teeny Dwyer’s boat off Dampier, Western Australia. When they stopped the boat the shark made multiple approaches and bit the boat’s propeller.

One of the persons on-board is attempting to hook the mako in the latter part of the video using a piece of tuna as bait. While the mako does grab onto the line at one point, the fisherman is never successful at actually hooking the shark in the footage shown.

Video: mako shark snatches fisherman’s mahi-mahi

YouTube user Redtale1106 captured some close-up footage of a shortfin mako (Isurus oxyrinchus) feeding on a mahi-mahi aka dolphin (Coryphaena hippurus) that had been hooked by one the fisherman aboard the boat the video was shot from. Unfortunately for the mako, it also ended up getting hooked by one of the fisherman.

According to a report at Florida Sportsman, the fishermen intentionally hooked the shark after it began biting their boat’s propeller. After a 30 minute fight, the shark was brought close to the boat and the line was cut.

Shark caught on camera in Hawaii waters – mako or white shark?

WARNING: Video features language that some may find offensive.

YouTube user kairokk posted a video featuring footage shot off Hawaii’s Kaena Point on January 12, 2012. The video shows a large shark circling a fishing boat and features some colorful commentary by the videographer. The shark in question is identified in the video title and throughout the video by the men on the boat as a great white shark, but a quick glance at the YouTube comments shows that there are others who are identifying it as a mako.

From the 2:08 mark until about the 2:15 mark gives about the best close-up view of the shark. So, to all the shark experts out there, is this a mako or a white shark? (My non-expert self is voting mako.)

The video above is the second in a series of footage of the shark, if you didn’t get enough from the clip above, check out the other clip.
