Man bites shark: what's really in your flake

Research has revealed that only a third of flake sold in fish and shops in South Australia is actually gummy shark. Other species included four endangered sharks. We speak to Professor Bronwyn Gillanders from the University of Adelaide to find out how endangered sharks are making their way into the fryer, and how food labelling regulations can be tightened up to protect sharks.Also, we chat to Dr Wenju Cai from the CSIRO about La Nina - and what happens now that three years of wet weather are coming to an end.Image: Gummy Shaker.
