Cape Town - A whale that became entangled in a 40-metre nylon rope was freed on Saturday afternoon near Gordon’s Bay in a meticulously planned rescue operation.

Employees from the department of environmental affairs, with the support of the National Sea Rescue Institute (NSRI), used sharp knives to cut free the one-year-old southern right whale, which presumably became entangled on Friday afternoon at Hangklip.

The crew of a boat in False Bay saw on Friday night how the whale was hitting the water with its tail and realised it was in distress and was probably tangled.

“But it was nearly dark and we decided to only go out the next morning,” said Mike Meyer, a spokesperson of the department for environmental affairs’ branch for oceans and coast, on Sunday evening.

“All along the coastline there are fish nets in which whales can become entangled. When a whale swims into a net, it starts turning round and round in an attempt to free itself. But that is actually the worst thing it can do because then it becomes more entangled.”

Infection

According to Meyer, a rope like that usually caught on the thin part of the tail, in front of the tail fin.

Often, as was also the case with this whale, there was a buoy attached to the rope. If an entangled whale was not helped, it could die eventually.

“The rope cuts into the animal’s flesh and it leads to infection.”

“The buoy keeps the animal on the surface of the ocean and prevents him from feeding and eating properly.”

“As this whale was helped within a day, he was not injured too badly,” Meyer added.

Officials from the branch asked the NSRI, tourist boats and other boats to look out for the whale on Saturday morning.

After they established that it was near Koeël Bay, NSRI volunteers took three members of the branch in NSRI boats to the whale.

Quick operation

They herded the whale to calmer waters in Gordon’s Bay.

They could then throw a kedge anchor on a rope toward him so that it could be fixed to the rope on his tail. Two buoys were tied to the rope so that the whale would remain on the surface.

Then they switched off the boat’s engines and carefully approached the whale. They pulled the rope toward them and carefully cut it off with sharp knives.

The rescue operation took about 30 minutes.

Cormac is currently on a 7 day expedition from Port Elizabeth to Port St Johns. The trip is an exploratory sea-going venture to gain a better understanding of the marine life on the South African East Coast. The trip has been organized jointly by African Diver and Rainer Schimpf of Expert Tours (www.expert-tours.com).

Rainer operates from his base at Port Elizabeth and this trip has long been an ambition of his. He also runs and NGO called Ocean Messengers (www.ocean-messengers.com) which focuses on ocean conservation.

Entries in the blog catalogue Cormac’s trip and the October issue of African Diver magazine will carry a full feature on it.

Day 2

Port Alfred to East London

After a lazy breakfast our little party left Port Alfred destined for East London. Once again the weather Gods had been kind to us and we delighted in another lazy sea day. That said, waves were crashing on the rocky coastline and leaving the harbour at Port Alfred was an exciting mad dash out of the harbour entrance once we caught a lull in the waves. Although we had a lazy sea, the sky was overcast and grey, but it looked like the clouds would burn off in a midday sun and we would be treated to blue skies again.

It didn’t take us long to find some excitement and we spent about an hour tailing a small Humpback family; two adults and a calf. This was consistent with our experience of the previous day when we had come across several small families of 2 adults and a calf.

Having left the Humpback family to their meanderings we headed into deeper water hoping to find some form of marine action. Great shafts of sunlight broke through the cloud cover in patches illuminating huge spot-lit areas of the ocean. Now and then blue sky broke over our heads, encouraging us to move ever deeper.

As the cloud cover broke up, in the distance, we caught sight of Gannets wheeling and diving and so we raced towards them. As we got closer it became apparent that the Gannets were following a mega-pod of Common Dolphin. The pod was spread out and was obviously hunting. Every now and then the dolphin would isolate a school of fish and the Gannets would wheel in and dive into the water to feed. The dolphin and Gannet were hunting Garfish and not Sardines as we had hoped.

The dolphin, were in a playful mood and each time we sped up they swiftly slipped into our bow wave to surf in front of our boat. Because the pod was so spread out we were able to “work” a very large patch of the ocean and “play” with them.

At some stage during all of this activity the pod came upon a two families of Humpback Whale and we were treated to the magnificent experience of having two species of cetacean sharing the ocean with us.

By now the sun had won its battle with the clouds and the sky was a magnificent azure and so was the ocean. It was too inviting to miss and so we kitted up and joined the dolphin in the water. Visibility was a magnificent 20 meters and clear of phytoplankton. Sunrays danced in front of us as it pierced and illuminated the waters beneath us.

We could hear the clicks and squeaks of the dolphin but also the deeper rumble of the Humpbacks. With so much activity the ocean sounded like a high street in Johannesburg in peak traffic.

We realised we were in the path of the oncoming whales and readied our cameras in the hope of a once-in-a-lifetime shot …

Little did I know just how once-in-a-lifetime that experience would be. For the full story and images, catch the October issue of African Diver, out on 1 October.

Rescue workers in Madagascar were battling to save a group of humpback whales beached on the southern tip of the island, where a fuel spill from a Turkish freighter threatens an ecological disaster, local media reported Thursday. The MS GULSER ANA, bound for India with a cargo of 39,000 tonnes of phosphates, had to be abandoned by its 23-strong crew on August 26 a few kilometres off Cape Sainte Marie on the vast Indian Ocean island.

Environmentalists and vets are trying to save a number of beached whales, whose blowholes had become blocked with diesel and oil and were close to death.

The cause of the accident to the 189-metre long, 30-metre-wide ship is still unclear. But a statement from Prime Minister’s Monja Roindefo’s office on Thursday said the ship’s cargo comprised far great quantities of diesel and oil than initially thought.

This protected part of Madagascar’s coast is famous for its rich coral reefs, rare species of tortoise and the migrating humpback whales that pass by at this time of year en route to their breeding grounds off Reunion Island.

Fish have also been washing up dead on beaches in the area, which is home to around 2,000 people living in four villages who rely on fishing for an income. The government has announced the suspension of all fishing in the area.

Some 800 people, including nine foreign experts in marine pollution with specialist equipment, have been sent to the remote area to treat the oil slick and clean up the beaches. The prime minister and four of his ministers have also travelled to the remote area by plane from the capital Antananarivo.

The government of the impoverished island has threatened to sue the ship’s owners over the spill.

The ship was reportedly on a blacklist of ships banned from European Union harbours.

Clean-up operations following the grounding of a Turkish-flagged vessel off the coast of Madagascar have started and damage to the environment should be limited, the ship’s operator said in a statement received by AFP Saturday.

The MV Gulser Ana grounded off Faux Cap, on the southernmost tip of the Indian Ocean island, on August 26, damaging its bunker tanks and releasing fuel oil in the sea, the Mardeniz Denizcilik company said.

“The owners, … pollution clean-up experts, are carrying out beach cleaning operations to remove any bunker oil residues arising from the initial escape,” the statement said.

“Anti-pollution experts are working with local residents who are receiving training, equipment and payment in order to assist with this task and we would like to thank them for their hard work and efforts,” it added.

The operator said the ship’s cargo of 40,000 tonnes rock phosphate — a kind of fertiliser — did not pose a threat to the environment.

“Sea currents are carrying any fuel oil to the east and away from the Cap Sainte Marie Marine Reserve and the coral reef, which should avoid any long or medium term environmental damage to the area,” it said.

The operator obviously is not only ignorant but also lying in the public statements, saying: “Over-flights of the area have not shown any evidence of whales or other sea mammals in the area having been in any way affected.”

The operator added that the ship’s 23 crew had been rescued by the Madagascar coast guard and were ashore.

The island relies heavily on tourism and is home to two percent of the globe’s total biodiversity. The majority of its animal and plant species are found nowhere else on Earth.

Rescuers battle to save whales - sapa
Rescue workers in Madagascar were battling to save a number of humpback whales that have beached on the southern tip of the island, where a fuel spill from a Turkish freighter has caused extensive pollution, local media reported on Thursday.

The MS Gulser Ana, which was bound for India with a cargo of 39 000 tonnes of phosphates, has leaked several hundred cubic metres of diesel and oil, as well as its cargo, since running into trouble on August 26 a few kilometres off the vast Indian Ocean island. The ship has since completely sunk.

The 23-member crew was rescued unharmed from the 189-metre-long ship, from which smoke was seen billowing at the time of the rescue. The cause of the incident is still unclear.

Several kilometres of the coastline, famous for its rich coral reefs, rare species of tortoise and the migrating humpback whales that pass by at this time of year en route to their breeding grounds off Reunion Island, have been polluted by the spillage.

Close to death
L’Express reported that veterinarians were trying to save a number of beached whales, whose blowholes had become blocked with diesel and oil and were close to death.

Fish have also been washing up dead along the coast.

The ship was reportedly on a blacklist of ships banned from European Union harbours.

Some 800 people, including nine foreign experts in marine pollution with specialist equipment, have been sent to treat the oil slick and clean up the beaches.

The government of the impoverished island, where fishing and tourism are key employers, has threatened to sue the ship’s owners over the spill.
Regional analysts presume foul play to be at the core of the tragedy, since the owner wanted to get rid of the vessel anyway and some believe its straight insurance fraud.

There is further confirmation that endangered southern right whales are returning to calve and nurse in Tasmanian waters.

Southern right whales calved and nursed their young in large numbers in Tasmanian waters until the early 1800s, when they were hunted to near extinction.

Two weeks ago a biologist photographed a mother and her calf in sheltered waters off Swansea, on Tasmania’s east coast.

Now biologist David Pemberton says a Victorian whale expert has confirmed the calf was born one or two days before the photo, and that the mother had been in the area for at least three days.

Mr Pemberton says an abalone diver has also seen a southern right whale give birth off Tasmania’s wild west coast.

“There’s some neat little bays hidden there and these animals go so close to shore when they are birthing and nursing that they find these little quiet spots - and that’s what we’re after,” he said.
