Protection of Sperm Whales: MSC avoids Hellenic Trench
Shipping has been proven to be problematic for marine mammals such as whales and dolphins, as accidents that can be fatal for the animals keep happening. Not only contact with propellers, but also the noise can have a serious impact on the marine mammals. According to the NGO Ocean Care, the shipping company MSC is now reacting to the fact that a largely isolated population of 200 to 300 sperm whales lives in the Hellenic Trench. The routes are being changed for both cruises and freight connections in order to avoid collisions that can be fatal for the animals. The organization considers MSC's decision to be "long overdue" and welcomes it in the interests of whale protection. It is calling on other shipping companies to follow its example, "because this is one of the sperm whales in the eastern Mediterranean's last chances of survival." Researchers estimate that there are around 5.000 to 200 sperm whales living in the Hellenic Trench, which is up to 300 meters deep. They are said to stay there all year round and are thus largely isolated from their conspecifics that are native to other regions of the world. Sperm whales are particularly often affected by involuntary collisions with ships. No one knows the exact cause of this, but it is likely to be due to species-specific behavior.
