Tagged controversy

ABC feature on criticism of “catch and release” tagging technique of great white sharks

Dr. Michael Domeier’s “catch and release” technique for tagging sharks, which was employed last year at Guadalupe Island and featured on a new National Geographic series, has come under some criticism from other shark researchers, as of late, after the technique was used on two sharks off the Farallones Marine Sanctuary. San Francisco’s ABC-7 ran the following report yesterday on the topic.

The incident involved with the shark at the Farallones, in which a portion of the hook was left in the white shark’s throat, is sure to draw criticism from those who believe this technique is too invasive and harmful to the sharks involved. The incident also lends support Peter Klimley’s remarks that the costs might outweigh the benefits of this technique.

What jumped out at me the most, while watching this feature, was the fact that when the technique was first covered by Outdoor Magazine in the article Great White!, the article stated, “While it’s fishing in every sense of the word, it’s imperative that the sharks are released into the sea unharmed and unstressed.” Domeier’s comments in the ABC-7 report indicate that stressing the shark is an important aspect of the technique. However, the statement in the Outdoor Magazine article is not directly attributed to anybody involved in the research, so it might have been an error on the part of the author, John Burgman.

I have little doubt that Domeier has good intentions with this tagging program, and that the goal of the program is to gain more knowledge of the species, by doing multi-year tracking (which Domeier says is not possible with the harpooning method), in order to help protect white sharks. Domeier has a long-standing track record of white shark research, which can’t be ignored. However, I have a feeling that those who are critical of the technique will be put off by Domeier’s demeanor and perceived attitude displayed in the interview clips featured in the ABC-7 report (which may have been a result of clever editing, for all I know). In addition, the photo of the team apparently in a gung ho cheer after landing one of the white sharks at Guadalupe island probably won’t sit well with critics, either.

For more commentary on the subject, check out Shark Diver’s Underwater Thrills post and Pete Thomas’ post at the LA Times Blog, which features a response from Dr. Domeier in the comments section.

Amos Nachoum photos from Guadalupe appear in major UK media outlets

UK media outlets, The Sun, the Telegraph, and the Daily Mail, have all run photos from Amos Nachoum taken at Guadalupe this fall. The one photo in particular that seems to be drawing the most attention from the media outlets is head-on shot of a “smiling” white shark that the media outlets are comparing to the character Bruce, from Pixar’s Finding Nemo.

While it might not resemble Bruce, this photo shows you can take a close-up of a smiling great white shark from inside a cage.
This photo might not look like Bruce from Finding Nemo.
But, it does show that you can take a close-up of a smiling great white shark from inside a cage at Guadalupe.

While the head-on shark photo may be the center of attention for the average viewer, I have a feeling that one of the other photos, which features an underwater photographer diving cage-less in close proximity with a white shark, will likely cause some shark diving operators to cringe when they see it. Amos’ decision to take recreational divers cage-less at Isla de Guadalupe recently drew sharp criticism from some shark diving operators, as well as shark diving blogs, including Underwater Thrills: Swimming with Sharks and The Best Shark Dive Ever, due to the fact that it is against the law to offer cage-less dives on a commercial level at Isla de Guadalupe. The appearance of these images in the mainstream UK media probably are not going to alleviate that criticism, as Mr. Nachoum’s media promotion of this illegal dive will likely serve only to further threaten legitimate dive operations at Isla de Guadalupe.

Following hot on the heels of the “monster shark” hysteria, The Sun refers to the white shark in the photo as “giant,” while the Daily Mail calls it “gigantic.” The actual length of the shark was reported as 14′ (4.25 meters) in length.
