Expert Links Dolphin Deaths to Sonar Testing

Did offshore oil exploration play a role in the recent deaths of nearly 900 dolphins off the northern Peruvian coast? Peru’s fisheries minister said last week that government scientists had ruled that out as a possibility and that the dolphins probably died of natural causes. But a marine veterinarian and conservationist who examined many of the corpses contends they were probably harmed by sound waves from seismic tests used to locate oil deposits. dolphin

As we reported earlier this month, the dolphin deaths, which overlapped with a large die-off of seabirds, have been the focus of intense speculation in Peru and around the world.

The marine veterinarian, Carlos Yaipen-Llanos, who is president of the conservation group Orca Peru, said in an interview that necropsies that he and his colleagues performed on three separate expeditions indicated that the dolphins examined were bleeding in their middle ears and had suffered fractures there. They also had gas in their solid internal organs and severe acute pulmonary emphysema, symptoms consistent with death from decompression sickness — that is, the bends, he said.

South Korean Captive Dolphins have a Shot at Freedom

In First-of-its-Kind Ruling, Judge Orders Release of Five Captive Dolphins

South Korea could be well on it’s way to becoming a dolphin-friendly nation. Like many other countries, it has captive facilities where dolphins are made to perform degrading tricks and live in unbearably small tanks. But a recent ruling on the case of five illegally captured bottlenose dolphins is making waves in the country’s animal rights, as well as animal industry, circles.Captive

Pacific Land, a theme park on the south coast of Jeju Island, is an abysmal prison for it’s captive dolphins — 11 of which were illegally purchased from local fishermen between 2009 and 2010, according to local activists. Of these, five remain alive and on perpetual display in a tank that is smaller than an Olympic-sized swimming pool. When they are not performing, they are forced to live in an underground holding pool, meaning that these dolphins have been living for years without ever seeing natural daylight.

The good news is that last month the president and a director of the park, known only by their last names Heo and Koh, were found guilty of buying the illegally caught dolphins. The duo have been sentenced to eight months in prison, fined US $8,760 and – most importantly – ordered to release the five surviving dolphins back to their natural habitat.

The ruling is the first of its kind in South Korea, which had no animal welfare laws until 1991. It comes on the heels of Seoul Mayor Park Won-soon’s order for the release and rehabilitation of a male dolphin at Seoul Grand Park, a major theme park in Korea’s capital city. The dolphin, named Jedoli, is one of the 11 Pacific Land had bought from fishermen.

Confusion Over Swiss Captive Dolphin Deaths

Previous veterinary reports regarding the cause of death of two dolphins at a Swiss dolphinarium last November have been thrown in to doubt following the leak of a new report which suggests the animals died from the effects of a heroin substitue.

The original evaluation by the Institute for Veterinarian Pathology revealed that the use of antibiotics on two dolphins (“Chelmers” and “Shadow”) at the Connyland dolphinarium, Switzerland last November caused brain damage which then led to their deaths.

An investigation into procedures followed by the vets responsible for the two dolphins then began. However, the leaked report now suggests that the dolphins were probably killed by a heroin substitute placed in the water at a zoo after it hosted a weekend rave. If this were the case then the drug may well have interfered with the dolphin’s natural instincts regarding when to surfaces to breathe.

The dolphinarium had previously accused animal activists of poisoning the dolphins.

Dolphin in Wetlands May Have Been Chased There, Rescuer Says

A dolphin that has made a temporary home in shallow waters off Southern California’s coast may have been forced there by a brutish band of other dolphins, says a wildlife expert who tried to steer it toward open water this weekend.

“He was scared. He was intimidated. He was bullied,” Peter Wallerstein, director of El Segundo-based Marine Animal Rescue, told The Los Angeles Times.

On Friday morning, the black-and-white common dolphin was found swimming in circles 12 feet from the shore in the Bolsa Chica wetlands south of Los dolphin_bullied_huntington_beachAngeles. Officials told ABC News affiliate KABC Friday that the dolphin appeared disoriented and stressed and could be at risk of suffocating in the low waters.

Wallerstein said Monday that when wildlife rescue crews had tried to help the dolphin move back into the ocean Saturday, a group of dolphins appeared, thrashing around and attacking the loner. Wallerstein said the dolphin eventually retreated back into the channel.

Cause of 3,000 Dolphin Deaths in Peru Likely to Remain a Mystery

Since mid-January, an estimated 3,000 dolphins have been found dead along the shores of northern Peru, in what has become one of the largest marine mammal dolphin-perumortality events ever reported.

Thus far, no cause has been determined, although evidence of middle- and inner-ear damage, lung lesions and bubbles in the blood are consistent with acoustic impact and decompression syndrome, leading to speculation that oil exploration in the region may be to blame.

In a statement released earlier this month, BPZ Energy confirmed that it was conducting acoustical, seismic studies in the area, but that the dolphin deaths began more than 2 weeks before exploratory activity commenced.

In the majority of large marine mammal strandings, no definitive cause is found – in part, because multiple factors are frequently at work. Toxic pollutants, for example, might weaken an animal’s immune system, making it more vulnerable to bacterial or viral infection. Persistent organic pollutants that accumulate in organisms further down the food web also tend to become more concentrated in top predators such as dolphins.

Countdown to extinction continues for world’s rarest dolphin

Just 100 Maui’s dolphins left alive
January 2012. Another one of the world’s last 100 Maui’s dolphins died in fishing net in New Zealand. Its death is a another stark reminder that measures to protect the world’s dead_mauis_nabumost endangered marine dolphin against fisheries bycatch are inadequate to prevent their extinction.

Gill nets
Like their closely related cousins, the Hector’s dolphins, Maui’s dolphins are only found in New Zealand. Since nylon fishing nets came into use in the 1970s, entanglements in gill and trawl nets have decimated Maui’s dolphins by more than 90 Percent. The animals are now down to just 100 individuals.

Just 25 females left
“With no more than 25 adult females left, Maui’s dolphins are perilously close to extinction. If mortality exceeds one individual in 5 to 7 years, the species will continue to slide towards extinction, just as it has done for more than three decades”, warns Dr Barbara Maas, Head of Endangered Species Conservation with NABU International – Foundation for Nature, Germany’s oldest and largest environmental associations.

“Absolute protection against commercial and recreational gill-netting and trawling is the only way to prevent their demise,” she said.

Whale And Dolphin Death Toll During Deepwater Disaster May Have Been Greatly Underestimated

The actual numbers of whales and dolphins killed following the Deepwater Horizon oil disaster last year could well be up to 50 times higher that first thought according to a Canadian and American research team.

In a paper published this week, the team suggests that 100 dead dolphin washed up on the shores of the Gulf of Mexico represent a small fraction of fatalities. Continue reading ‘Whale And Dolphin Death Toll During Deepwater Disaster May Have Been Greatly Underestimated’ »
