Sea turtles have been making it to the top of the headlines recently, all positive for a change and I thought I would use this blog to draw attention to this. Additionally, I feel it’s always nice to give some attention to the turtles.
So the first piece of news, the secrets of the sea turtle migration have been uncovered. It turns out that the reproduction migration (females returning to their nesting beaches) is not the longest migration that sea turtles carry out. It has been found from the compilation of long term capture programs that the migration of immature turtles, termed “developmental migration”, is longer than the reproductive migration. Also this migration is only carried out once in their life time rather than every few years. On the migration topic as well, a study was carried out to determine the migration of juvenile leatherback sea turtles. However, due to the size and the weight of the juveniles it is impossible to attach a satellite tag to their shells without them sinking. So instead of following the hatchlings the scientists followed the currents. The “lost years” of a turtle’s life, the age between hatching and returning to foraging grounds can be anywhere between 3 to 5 years after they hatch. These years are the least understood part of a turtle’s life. Knowing more about where the turtles swim before they reach adulthood could be critical in protecting the species. Continue reading →
The Smithsonian Tropical Research Institute has released a free iPhone app, for the identification of Pacific fish species. The species covered spans from Baja California to Ecuador, including the Galapagos.
The app evolved from the book, “Fishes of the Tropical Eastern Pacific” published in 1994. However, the app covers over 1,300 species allowing the identification of 10% of the world’s tropical fish species whereas the book only has 700. The app is free on iTunes: here and is potentially one of three apps according to iTunes descriptions.
Having downloaded and played around with this app it is very easy to use. It has a clear lay out containing a notebook section where you can compile your own lists and each page comes with a glossary section for any words used that aren’t understood. When you click on one fish you will also see other members of the family before it goes directly to the profile page, allowing for a perfect match. I like the feature of being able to find out the IUCN red list status which is available on each profile page. A useful little app that I would recommend to anyone needing to identify any pacific fish species!
After watching Ric O’Barry in The Cove, it’s hard not to want to free any dolphin you come across in captivity. O’Barry has been at the forefront of dolphin rescue since the ‘70’s, after watching Kathy, one of the five dolphins who played Flipper, commit suicide in his arms. O’Barry is now working to free the largest member of the dolphin family: the orca. Along with a former SeaWorld trainer, two other marine mammal experts, and PETA (People for the Ethical Treatment of Animals), O’Barry is listed as a “near friend” of Tilikum and Katina from SeaWorld Orlando; and Corky, Kasatka, and Ulises from SeaWorld San Diego. The five orcas are named as plaintiffs in PETA’s lawsuit against SeaWorld. Tilikum is the orca that grabbed and killed his trainer in 2010.

PETA is asserting that the whales are, in effect, involuntary servants: held in captivity, ripped from their families in the wild, subject to sperm collection and artificial insemination, and forced to perform; all for SeaWorld’s profit. PETA is arguing that this is illegal… under the 13th Amendment, which abolished slavery in 1864. PETA claims this is the first suit of its kind: seeking to apply constitutional rights to animals.

Reading the new 2nd edition of Erich Hoyt’s MPAs for Whales, Dolphins, and Porpoises gave me a lot to think about. What a fascinating topic and the book is… I’m not sure I have words. It is an impressive volume packed with information on cetacean species, highly detailed information on their habitat and migratory patterns, and lots of background on Marine Protected Areas (MPAs).
1. MPAs are a complex, but critical strategy to protect whales, dolphins, porpoises and other marine species. What are some of the biggest constraints to the success of MPAs and what are some steps to help overcome them?
EH: One constraint is getting them implemented. All MPAs start out on paper. It can be in the interests of government, industry or certain stakeholders in keeping them only on paper. There is inertia of course, too. Many areas stay as paper MPAs for years. I always say that all MPAs start out on paper but it is up to the stakeholders — the local communities, researchers, government ministries, conservation groups and those who care — to work separately and jointly to make them real MPAs that function to help protect marine wildlife and ecosystems. It is also important to realize that once effective protection is put in place, it is necessary to monitor and review the situation from time to time and make changes as needed to keep the MPA functioning and, indeed, improving.

A powerful and factual documentary on the often emotional issue of keeping cetaceans (whales & dolphins) in captivity.
A FALL FROM FREEDOM is the first film to expose the long and sordid history of the captive whale and dolphin business; a history that continues to this day. The illegal capture and transport of killer whales, the thousands of dolphins that are killed in order to provide marine parks and aquariums with replacement animals, and the ability of these facilities to miseducate the public about these animals.
These, and many other issues, are covered in graphic detail in this 80 minute film.
