INTERNATIONAL COASTAL CLEAN UP

September 29, 2010 by dyertrust

Dyer Island Conservation Trust recently joined forces with Overstrand Municipality Gansbaai Administration in placing unique fishing line disposal bins.

Biologist Katja Vinding Petersen and I headed out on International Coastal Clean Up Day to visit the local angling shops and boat clubs to spread the word. The response has been overwhelmingly positive and the community very supportive of the project. We drove past the bins at Franskraal and Gansbaai harbour and were very pleased to see they are being used. Not only can fishermen use them but those members of the public who are passionate about cleaning up their beach areas.

HUMPBACK WHALE SAMPLING

September 28, 2010 by dyertrust

A call was received telling us about a washed up whale at a nearby stretch of beach called Die Plaat.The crew headed off to gather samples which we send to Mammal Research Institute (University of Pretoria) and Oceans and Coasts (Department of Environmental Affairs).

It was a juvenile humpback male whale, 10.2m long. Although it was in a good condition with a thick layer of blubber, it was starting to decompose so we could not do a full necropsy. Cause of death uncertain at this point. There were some post mortem shark bites and no boat marks that were evident.

SEVERE ENVIRONMENTAL DAMAGE CAUSED BY FISHING LINES

September 27, 2010 by dyertrust

The Dyer Island Conservation Trust (DICT) in association with Overstrand Municipality, Gansbaai Administration, is very excited to be establishing the Fishing Line Recovery and Recycling Program (FLRRP) along the Gansbaai shoreline, with specially designed disposal bins.

This innovative project aims to reduce the severe environmental damage caused by discarded fishing line on our coastline. Monofilament fishing line is non-biodegradable and can last for up to 600 years in the marine environment where it entangles wildlife, is mistakenly ingested by birds and animals, resulting in injury or death, and is also hazardous to boaters and swimmers.

OILED AND INJURED PENGUINS OFF DYER ISLAND

September 26, 2010 by dyertrust

This August the Dyer Island Conservation Trust has rescued eight oiled penguins. It is not always possible to identify the source of the oil it could be from old wrecks still seeping oil or more likely an illegal dumping. Another three penguins have been taken in with shark bite injuries.

The Trust serves as the animal rescue centre in the area and works in close partnership with SANCCOB the centre for coastal bird rehabilitation in Cape Town; Two Oceans Aquarium; and Penguins Eastern Cape.

BRYDES WHALE SAMPLING AT PRINGLE BAY

September 25, 2010 by dyertrust

Monday morning the 12th of July, turned out to be like all other days here at DICT full of great surprises and excitement. We received a phone call from Penelope Aplon, Environmental Manager of the Overstrand Municipality, about a dead washed up whale at Pringle Bay beach.Wilfred Chivelland I grabbed our rubber boots, stranding kit and oil-skins and within 10 minutes we were on the road heading to Pringle Bay.

It is always exciting when whales are found stranded. Of course we would rather see them alive in the ocean, but when they do die and wash ashore there is so much information for us as scientists to obtain. Skin samples can be used for DNA-analysis, which can tell us the sex of the individual as well as the relationship to other animals in our databases. The baleen as well as blubber can be analyzed for isotopes and fatty acid composition, which enables us to trace back the composition of the animals diet, since species specific isotopes are found in different fish species as well as krill. If it is a toothed whale, we can use the teeth to estimate the age of the animal, by counting the layers of dentine in a cross section.

Southern Right Whales

September 05, 2010 by dyertrust

Southern Right Whales (Eubalaena australis)

Southern right whales are large baleen whales. The average size of an adult is approximately 15 metres, but they do grow larger. These whales are filter feeders and they sieve copepods (small planktonic organisms) from the water using huge baleen plates, which hang from the roof of their mouth. This species has a three year breeding cycle, with each female producing one calf every three years. They migrate to our sheltered bays in winter to have their calves, and most are born around August. At this time, some individuals will be mating. When they are not here in South Africa, they are in the Antarctic in their rich summer feeding ground

CAPE FUR SEALORDER:PinnipediaFAMILY:OtariidaeGENUS:ArctocephalusSPECIES:pusillusSUBSPECIES:pusillus

The Cape Fur Seal breeds at > 40 colonies in southern Africa between Algoa Bay (Port Elizabeth) and baia dos Tigres (southern Angola), at mainland sites or on islands nearby the coast. There have been several new colonies established in recent decades. In South Africa, seals are protected under the Seabirds and Seals Protection Act, and they are faced with threats such as being drowned in active fishing nets or being deliberately killed by fishermen. They often become entangled in marine litter such as discarded nets, fishing line, or plastic.

Dyer Island Blog #8 06 October 2009

Major news the past few weeks in South Africas marine environment was the grounding of the bulk carrier Seli 1 shortly before midnight on Monday 7th September at Blouberg in Cape Town. This 29-year- old Turkish ship was headed for Gibraltar and was carrying 660 tons of fuel and 30 000 tons of coal.
