Whale-watching comes under scrutiny at South Africa meeting

“A large vessel that parks right next to the animals can potentially disturb those animals from doing those activities,” he said, citing cases of mothers separated from their young by an approaching vessel.

Walker described South Africa as a “world leader” in responsible whale-watching, saying strict license limits mean there is only one commercial operator in stretches of water along many parts of the coastline.

Scientists are studying the potential effect of repeated whale-watching on the behaviour of individual whales, including any changes in feeding, reproduction and mortality rates, said the International Whaling Commission, which oversees conservation of the marine mammals and manages whaling.

The research has led to whale-watching measures including “limits on vessel numbers, speeds, approach distances and time spent with whales, and a variety of training and permit schemes,” according to the commission. Over 50 countries have whale-watching guidelines or rules, it said.

Whale-watching boats in Madagascar must have a monitoring guide — paid or a volunteer — on board, said Francois Xavier Mayer, scientific adviser for Cetamada, a non-profit group that aims to protect marine mammals and their habitats. The group is co-hosting a forum next week on Reunion, a French island in the Indian Ocean, to discuss humpback whales, whose population has increased annually by 10 per cent in some areas, including off southern Africa, South America and Australia.

A group in Greece, meanwhile, is setting up a marine sanctuary in a bay on the island of Lipsi to rehabilitate any captive dolphins released from marine parks. Public unease with the treatment of dolphins in such entertainment facilities is growing, said Anastasia Miliou, scientific director at the Archipelagos Institute of Marine Conservation in Greece.

There are 300 captive dolphins in Europe, out of 2,000 worldwide, Miliou said.

“We are hoping to bring back respect to dolphins,” she said.
