Despite efforts to try and protect the Port River dolphins, Australia, some boat users are still going at full speed within the Adelaide Dolphin Sanctuary. Impacts from speeding boats have been the cause of young dolphin deaths within the sanctuary in recent months and out of seven calves born in the Adelaide Dolphin Sanctuary this season, only three have survived. One calf killed, was only two weeks old.
A recent report found that 17 out of 35 dolphin fatalities in the past 13 years were caused by speeding boats and conservation groups are now calling on the State Government to introduce a 10-knot speed limit throughout the dolphin sanctuary in a bid to try and prevent these tragedies.
The sanctuary which covers 118 sq. km was declared in 2005 as a protected zone for the dolphins.
