Hi Bos Suzi, as mentioned, you should be quite safe. As far as I know there has never been an attack on people, animals or boats on that river. Before that 650 kg one was caught, people used to swim in the river with their dogs, me included, and nothing ever happened. Those sharks are more interested in your catch than anything else. They have adopted the habit of lying under an anchored boat and wait for the angler to pull in a fish, which they grab. There is enough food in the Breede to keep them happy, so don't worry about them. Enjoy the fishing.
