On Saturday the 25th of November a deceased white shark was reported to the South African Shark Conservancy by Ichthyologist, Sarah Halse, from the Breede area. On Sunday the 26th, Dyer Island Conservation Trust’s white shark biologist, Alison Towner, retrieved the shark and brought it back to DICT’s Kleinbaai facility.

This Women's Day we celebrate our Conservation Heroes, right here in Gansbaai. Our team of marine biologists and conservationists working for the Dyer Island Conservation TrustAfrican Penguin and Seabird Sanctuary – APSS, Marine Dynamics & Dyer Island Cruises share with us what drives them to protect the unique Dyer Island ecosystem, home of the Marine Big 5.

Last year in January 2016, the great white shark diving industry based in Gansbaai South Africa experienced a challenging period where practically no white sharks were observed at any boat-for almost an entire month…

 We headed out from Kleinbaai harbour to the shallows in hope of spotting some nice sharks! Our first shark timed our divers perfect..

We are lucky enough to have many Great Whites visit our vessel whilst out on the water. Some of these individuals are easily identifiable due to scars, pigmentation, tags, notches in dorsal and caudal fins and also missing pieces from their fins. Some have earned names for such interesting, distinguishable features and have also been seen to have distinctive personality traits to match as well! It is my pleasure to introduce a few of our favourites…

A wonderful Dyer Island trip with clear visibility and plenty of shark action…
