Hawksbill turtle

Two years after their detainment, 13 poachers, from Vietnam, who were caught with the dead bodies of 101 endangered Hawksbill turtles (known in scientific circles as Eretmochelys imbricata) near El Nido, northern Palawan, in the Philippines, have finally been convicted and sentenced to hefty fines along with some jail time.

On the 22nd of June, The Regional Trial Court of Puerto Princesa, Branch 50, after much deliberation, decided that the Vietnamese poachers should face jail time for their heinous acts, and will receive anywhere from 6 to 18 months, plus have some hefty fines to pay.

Since the poachers have been sitting in jail since the 2nd of September 2008, the court also decided that they will only have to cough up the money for the fines.

Two Filipino gunboats apprehended the Vietnamese boat transporting the poachers five miles east of Cabaluan Island near El Nido on August the 29th 2008. In a sheer act of desperation, the 13 crew members aboard the boat tried to sink her by flooding the holds, however were preented from doing so by law enforcement officers.

When the cargo holds were explored, they discovered the corpses of 101 Hawksbill Turtles, classified as being critically endangered, which is the highest risk rating for any living animal. This rating was handed down by the IUCN, the International Union for Conservation of Nature, some time ago.

So, they did the crime, they served the time, now all that remains is for them to pay the fine… Although, is it really enough? Did the poachers learn their lesson? Or were they simply sorry they were caught?

More than 30 sea turtles have washed up in Guatamala’s southern coast, dead, mutilated and showing signs of suffocation, authorities have reported.

The National Council of Protected areas has said that the turtles were discovered on the beaches of Sipacate and Monterrico.

Upon closer examination the turtles appeared to have succumbed to suffocation after having been trapped in fishing nets, the organization went on to explain, they added that the fishermen responsible were using fish hooks in zones labeled as being “off limits”.

According to the law of Guatamala, fishing nets are supposed to have a turtle excluder device (TED), which will allow any turtles trapped by accident to escape quickly, easily and unharmed.

The reason that this is most troubling is due to the fact that the nesting season has just gotten underway, and there are already efforts in place to protect these magnificent turtles which are already threatened. This statement comes from the head of the organization’s hydro-biological reources department, Jose Martinez.

There are six different kinds of sea turtle which nest in Guatamala, all of them are in danger of becoming extinct, due to human activities such as poaching, over harvesting of the eggs, and of course, pollution.

There are going to be further steps taken to help the protect the turtles, but it’s a big ocean, and there aren’t enough resources to provide for 24 hour surveillance of every nook and cranny.

Alligator Snapping Turtle

A fisherman, Steve Bellion aged 23, was out at Earlswood Resevoir angling for carp when he caught a little more than he bargained for. He managed to reel in a 57 lb (27 kg) reptile!

He dragged it to shore where it was easily identified as an 80 year old alligator snapping turtle. This is a rare catch indeed, as these turtles are generally only found in the eastern corners of the United States.

This has solved a rather puzzling mystery for the local fishermen. There has been many a tale told for a decade, of a giant creature biting through lines and roughing up ducks.

Alligator snapping turtle

The ancient Alligator Snapping Turtle, identified as being female, was transferred to the West Midland Safari Park, where it is going to be held in quarantine for the customary 30 days and checked over by the veterinary team there.

Alligator Snapping Turtles can live to be 160 years old, making it one of the longest living creatures to be hauled to shore in the area.

Once it has finished being checked over, it will be transferred to a vivarium with a male of the species.

“They have been known to attack small domestic pets or children, but I don’t think this one would have drifted to far from the water.” stated the director of wildlife at the safari park, Bob Lawrence. At first glance it seems that the turtle is in perfect health, as it should be after gorging itself on the local wildlife.

He went on to add that this really brings to light the danger of introducing foreign species into Britain’s waterways, much the same way that American signal crayfish have created quite a dip in the UK’s national crayfish population.

– BP is in some very hot water over their practice of burning sea turtles, while trying to clean up their mess in the Gulf of Mexico. The initiative is being headed by the Center for Biological Diversity and the Turtle Island Restoration Network.

They officially notified the U.S. Coast Guard and BP of their intent to launch a lawsuit for them to stop burning endangered sea turtles alive, and have given an ultimatum of 60 days in order to do so. If the action is not stopped a lawsuit will be filed under the Endangered Species Act.

Todd Steiner, biologist and executive director of the Turtle Island Restoration Network has this to say on the subject “BP is burning turtles alive and it is cruel, heartless and a crime we can’t and won’t allow to continue, sea turtles were critically endangered before BP created America’s worst environmental catastrophe, and every effort possible must be taken to rescue endangered turtles from this oil spill. BP needs to reverse course and help double our efforts to rescue sea turtles, not prevent their recovery.”

The spill really did happen at an inopportune time, as the rare Kemp’s ridley sea turtles started to nest in the Gulf of Mexico.

BP wound up in this mess, as they started a burning process, as they didn’t allow enough time for rescue boats to make a search, and get the sea turtles out of harms way.

Last month, 82 Green sea turtles hatched at SeaWorld in San Diego, California.

The eggs hatched on Shipwreck Beach and the youngsters didn’t need any human aid to get out of their shells and into the water. The park had decided to let nature take its course by refraining from incubating the eggs or help the hatchlings emerge. SeaWorld are now planning to dig up the beach to check if any buried eggs failed to hatch.

At the moment, the baby sea turtles are roughly one month old and only weigh a few grams. They happily feed on squid, shrimp, krill and special pellets. Assistant curator of fishes Tim Downing says they are all in excellent health and that they will go on display before the end of the year.

“There is so much that is not known about sea turtles,” said Downing. “We are getting real good information on the growth rate of juveniles. They are all gaining weight and doing well. We have done some X-rays, and they are progressing just like we would expect them to.”

SeaWorld is home to 30 adult sea turtles, including four Green sea turtles – three females and one male. They have been living at SeaWorld since the 1960s and are sexually mature, so all three females may have buried eggs in the sand. Only genetic testing will be able to reveal the maternity of each baby turtle.

All seven species of sea turtle in the world are endangered or threatened, with the Green sea turtle being listed as Endangered on the IUCN Red List of Threatened Species. It will be up to the National Marine Fisheries Service and the U.S. Fish and Wildlife Service to determine whether the new turtles will stay at SeaWorld and whether the adult turtles will be given opportunity to mate again next year.

“No matter how exquisite it may seem, as if it were some sort of magic, evolution is at most a good trick… and there is a way to make it work. In case of turtle evolution, a major part of the trick was found to be embryonic folding.”

Ever wondered how the turtle got its shell? So has a Japanese team of scientist and they decided to investigate the subject by comparing turtle embryos with those of chicks and mice.

In turtles, it is the ribs that grow outward and fuse together to form the shell, formally known as the carapace. Having your ribs folded around your body is such a great leap from being a soft bodied animal that scientists have long puzzled over how this change happened in the course of evolution. Just like mammals and birds, turtles hail from a soft-bodied ancestor without any external carapace.

Through their embryological studies, the Japanese team of researchers from the Riken Center for Developmental Biology in Kobe, Japan, was able to identify the key event in the development of a turtle embryo that changes its fundamental “body plan”; the moment when the upper part of its body wall folds in on itself, forcing the ribs outward. This folding process results in a thickening of the deep layer of the turtle’s skin that maps out the position of the shell. As the turtle embryo grows bigger, the folding prevents the ribs from growing inwards.

“In the early embryo, the muscles and skeleton are in similar positions to those of the chicken and mouse”, Dr Kuratani explains.

Last year, a 220-million-year-old fossil was found in China, consisting of a fossilized turtle with an incomplete shell covering the underside of it body.

“The developmental stage of the modern turtle, when the ribs have not encapsulated the shoulder blade yet, resembles the (body) of this fossil species,” says Dr Kuratani.

The team has not yet been able to determine what causes the folding to happen in the first place

“That belongs to a future project,” says Dr Kuratani.

Florida will soon have the strictest conservation law for the harvest of imperilled freshwater turtles in the U.S. The new legislation pertains to all freshwater turtles on Florida’s imperilled species list plus species that look similar to the imperilled species, which include common snapping turtles and cooters.

• Commercial harvesting of these freshwater turtles will be prohibited.
• Individuals will still be allowed to take these freshwater turtles for non-commercial use, but no more than one turtle per day per person.
• Transporting more than one of these turtles per day will be prohibited.
• Collecting freshwater turtle eggs will be prohibited.

Turtle farms that depend on turtles collected from the wild will still be allowed to collect turtles, but only if adhering to a strict set of rules and only in order to establish reproduction in captivity to make the farm self-sustaining.

“I believe this industry should be moved to aquaculture, said Rodney Barreto, chairman of the Florida Fish and Wildlife Conservation Commission (FWC). “That’s the logical place for it to be.”

The closed season for the take of softshell turtles, May 1 to July 31, will not change under the new rule.

Sorry for the silence over Halloween. Posting will now hopefully return to normal with at least one post every or every other day. This first post will be somewhat of a link post catching up on some of the fishy news that happened last week.

First of is an update on the Atlantic Blue fin Tuna. Despite good signs going into the Marrakesh tuna conference the outcome was very bad with the quote for eastern blue fin tuna being set to 22,000 tons, 50 per cent higher than scientific advice. Last years quota was 29,000 tons but it is believed that a total of 61,000 tons were brought ashore when counting illegal catches. These levels are unsustainable and the blue fin tuna populations are near a collapse. You can read more about this here

Another Tuna news. A fisherman out of San Diego is believed to have caught the largest yellow fin tuna ever caught. The tuna weighed in at 381.1-pound. View a video here.

Time to stop talking about tunas and start talking about something completely different, snakeheads. A new study has shown that snakeheads are proving much less damaging to the native fauna than expected. They do not seem to be destroying populations of native fish such as largemouth and peacock bass. The scientist examined the stomach content of 127 snakeheads and found one of the most common pray to be other snakeheads. They found 13 snakeheads, one bluegill, 11 mosquitofish, seven warmouth, two peacock bass, several lizards, bufo toads, small turtles, a rat and a snake. No remains of largemouth bass were found.

Another interesting article posted this last week is this one that tells the story of the mass gharial die of that happened last winter when half the worlds population of this once common animal. Scientist finally thinks they know why this happened. Something that might help save the worlds last 100 specimens.

That is it for this time but I might post more post like this during the week if I decide that there are more news that are to important to miss.
