Tagged White Shark Brenda captured, killed by Mozambique fishermen
October 31, 2012 by dyertrust
FOR IMMEDIATE RELEASE:
It has been confirmed that a 3.6 meter female White Shark tagged 8 March 2012 in Mossel Bay by the non-profit group OCEARCH and a team of leading South African scientists was captured and killed off the coast of Mozambique. Caught in a gill net, the shark given the name Brenda by the OCEARCH team was harvested by village fishermen who gave the meat to the village and sold the fins.
Chris Fischer, along with the scientists who worked with OCEARCH to tag over 30 white sharks off the coast of South Africa, were affected by the news. Said Fischer: "We were all saddened to hear of the demise of Brenda, a magnificent female great white shark." OCEARCH waited on issuing a statement until the facts were clear. Those facts, and the recovery of the transmitter, were obtained thanks to the perseverance of a team assembled by Hannah Darrin from Eyes on the Horizon, a local Mozambique NGO, and led by Gabriel Marime of Bitonga Divers. Jess Williams, another member on the team, took photos of the recovery mission.read more

Brenda was fitted with a SPOT tag in Mossel Bay during the Ocearch tagging program held earlier this year. Brenda's full track can be seen below. In the past week, the tag began transmitting repeatedly from a village in Mozambique.
"Pings over land are not uncommon, not every ping over land means the shark is on the beach," DICT researcher, Michelle Wcisel explains. "However, to get lots of pings in a small area over land is another story."read more

September Whale Blog
October 16, 2012 by dyertrust
The theodolite tracking is running like a well-oiled machine and the team has seen sightings of humpback whales almost every week. These animals seem to have changed focus from migration to social behaviour. They spend much more time breaching and their pattern is not as predicable as the migrating humpback whales in July and August.
A new addition has permanently joined the tracking station at the water tower. A bright green snake has moved in on the rail!! The team put it there to prevent the local white necked crows from decorating the top of the tower and attracting countless tiny flies.read more
Voortrekkers focus on the Penguins
October 10, 2012 by dyertrust
Every year we meet the Western Cape Grade 7 Voortrekkers group at Bettys Bay. They have this yearly get together where the focus is on the penguin, the environment and of course having some fun. We saw that they were making the most incredible lighthouse models and heard there was a fashion show out of plastic bags.
We had the opportunity to teach the children more on the work of the trust and share knowledge on our Marine Big 5. We showed them our latest model penguin home and our fishing line bin. There were lots of questions and we were kept on our toes. We gave each a copy of our latest Volkswagen sponsored activity books. They in turn sponsored another penguin home. Thank you Voortrekkers. See you again next year.
Acoustic tagged shark number 10
October 09, 2012 by dyertrust
Finally, the long days of Masters thesis writing chaos have subsided for both myself and my co scientist Oliver Jewell, which means more time for acoustic tracking (I never though Id cherish the noise of those continuously pinging radio transmitters so much!). During this month of September we managed to successfully deploy an acoustic tag onto a 3m female great white, just to the right side of her dorsal fin with a tagging pole. We named the shark ANAAR- after a donation from Anya and Arav Goel although she has become affectionately known as Anarchy due to her feisty nature. Boat based tracking then commenced immediately to retrieve GPS positions combined with real time temperature and depth data. Interestingly, the only other shark we have tagged in this size range, moved to Dyer Island where she remained for the duration of the track in February 2010. We have never recorded inshore movement data on a white shark female this size.read more
Hermanus whale festival 2012
October 08, 2012 by dyertrust
Thisis the third whale festival that the Dyer Island Conservation Trust has participated in. The tent space dedicated to the environmental aspect of the festival was greatly increased meaning more conservation organisations could be involved. Under the organisation of Kim Mclean, we exhibited alongside Sanccob, Shark Conservancy, AOCA and many others.
We had the opportunity to talk about our shark research, our African penguin nest project as well as our whale and dolphin studies. We won Best Presentations. Thank you to the judges. Most excitedly, we received the most awesome childrens activity books and birthday calendars from our corporate sponsor, Volkswagen SA. We had just as much fun as the children.read more
