IN addition to being a bustling, world class harbour, the Port of Richards Bay shares its sheltered waters with one of the country’s most endangered creatures – the Humpback dolphin.
While the mammals’ presence indicates a fairly healthy marine environment, various factors make them vulnerable to habitat degradation and ultimate demise unless they receive ongoing protection.
‘It speaks volumes that this port is still considered very much a functioning estuary, not only for dolphins but for a diversity of marine life forms,’ said marine biologist Shanan Atkins of Wits University and the Endangered Wildlife Trust.
‘Conditions here are ideal: fairly shallow and turbid water, and we believe this area clearly boasts the highest number of KZN’s Humpback population.’

Shanan has headed scientific research on Richards Bay’s Humpback dolphins since 1998 and presented many of her findings and concerns to the engrossed leadership team at the Port of Richards Bay on Thursday morning.
General information on these shy creatures’ numbers, habits, feeding patterns, breeding rate and other salient points was shared, with specific attention to threats for their future – including water pollution and the noise from ships and boats and other sources that could affect the dolphins’ sensitive eco-location function.
‘Top among dolphin mortality is entrapment in shark nets, and we are working hard to find a balance between bather safety, shark culling and dolphin protection,’ said Atkins.
She also circulated a questionnaire on perceptions on shark attacks, which again confirmed an exaggerated opinion of the dangers posed to bathers and the great need for public education.’
Port Manager, Preston Khomo pledged whatever support TNPA could give to dolphin research and said he and other port personnel would now be more sensitised to the presence and activities of dolphins within the harbour.
‘I am sure I am not the only one who has been ignorant of the presence and status of these creatures and have learned much from this presentation.’
