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.

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.
