Kip Evans Superb Documentary Effort

The waters around Isla Holbox off Mexicos Yucatán Peninsula teem with plankton, a feast for giant whale sharks—10-meter giants that gather by the hundreds from June through September. These super-sized but toothless filter feeders are the core of a local tourism industry, but over-development could threaten this delicate balance.

SSACN Searches for Shark Officer

The Scottish Shark Tagging Programme is delighted to announce they have been awarded a funding package worth £52,000 to help support their data gathering on species of sharks, skates and rays found in Scottish waters, many of which are at risk.

The funding has been offered by Scottish Natural Heritage (SNH) and the Argyll and the Islands LEADER Programme and will be used to employ a Shark Project Officer who will work with SSACN to further develop the Scottish Shark Tagging Programme (SSTP – www.tagsharks.com) whose objectives are to :

• Record data on shark, skate and ray species
• Increase public awareness
• Highlight the need for species protection
• Encourage use of “codes of best practice”
• Showcase conservation methods and efforts

Project Director Ian Burrett "SSACN has long campaigned for programmes aimed at regenerating the stocks of Scotland’s sharks; unfortunately the government and fisheries managers say they are unable to act as they say they lack the necessary scientific data and have no programme in place to gather it."

“Thanks to our funding partners and the many anglers who support our efforts, we shall be gathering that data for them.”

Tagging is the only non-destructive means of gathering the necessary data. It will be undertaken by volunteer sea anglers – fishing from the shore, kayaks or boats – who will catch, tag and release various shark, skate and ray species, either as part of their normal fishing trips or during major tagging events coordinated by the Shark Project Officer and SSACN.

The duties of the Shark Project Officer will also include arranging training workshops for anglers and raising awareness of Scottish sharks, skates and rays by liaising with fishermen, and visiting schools in Argyll.

Jane Dodd, SNH Marine Project Officer for Argyll and Stirling said: “We are hoping to recruit a dynamic project officer to lead this exciting project. Someone with project management skills and at least an interest in sea angling and a willingness to do some boat based field work. Quite an unusual range of skills to be found in a single person but we have our fingers crossed that he or she is out there!

Philopatry and migration of Pacific white sharks

Fascinating reading coming from The Proceedings of The Royal Society this week (click on image) with tracking/DNA data from a multi year effort at the Farallons, Point Reyes and Ano Nuevo off the coast of California.

Paper Highlights

"Hawaii is likely to be an important foraging area for white sharks. Extensive use of waters surrounding the Hawaiian island archipelago in winter and spring was evident from 13 satellite tag records (22% of tags with offshore tracks) and five acoustic tags (10% of 2006 and 2007 deployments) detected opportunistically by receivers stationed near the islands of Oahu and Hawaii (together comprising six males, six females and six unsexed individuals) (figure 1). The most precise geopositions and acoustic records from Hawaii included Argos endpoint transmissions (n = 8) with location errors of 150 m s.d. (Teo et al. 2004) and acoustic tags detected at fixed locations (n = 5). These occurred in slope and near shore waters along the entire 3000 km archipelago from the big island of Hawaii extending through the Papahānaumokuākea Marine National Monument to Laysan Island and Midway Atoll (electronic supplementary material, figure S2). While this distribution includes areas with colonies of endangered monk seals (Baker et al. 2007), detailed dive records from four recovered satellite tags (three females and one unsexed; three separate years) indicated that the dominant behaviour, when not transiting (Weng et al. 2007), was a precise diel vertical migration, between the surface and 600 m, consistent with foraging within the deep scattering layer community (Shepard et al. 2006) (electronic supplementary material, figure S3)."

The End of The Line - New Doco

If you go off the coast of San Diego and drop in a cage looking for blue sharks, you'll spend a lot of time looking for them. Since 2000 the population of adult animals has plummeted. A new documentary looks at this phenomenon in a global perspective using science - not green hysteria to bring home the message:

The End of the Line, the first major feature documentary film revealing the impact of overfishing on our oceans, had its world premiere at the Sundance Film Festival in the World Cinema Documentary Competition. Sundance took place in Park City, Utah, January 15-25, 2009.

In the film we see firsthand the effects of our global love affair with fish as food.

It examines the imminent extinction of bluefin tuna, brought on by increasing western demand for sushi; the impact on marine life resulting in huge overpopulation of jellyfish; and the profound implications of a future world with no fish that would bring certain mass starvation.

Filmed over two years, The End of the Line follows the investigative reporter Charles Clover as he confronts politicians and celebrity restaurateurs, who exhibit little regard for the damage they are doing to the oceans.

One of his allies is the former tuna farmer turned whistleblower Roberto Mielgo – on the trail of those destroying the world's magnificent bluefin tuna population.

Filmed across the world – from the Straits of Gibraltar to the coasts of Senegal and Alaska to the Tokyo fish market – featuring top scientists, indigenous fishermen and fisheries enforcement officials, The End of the Line is a wake-up call to the world.
