A leading dolphin expert says the fishing industry is using diseases like toxoplasmosis as a scapegoat for dolphin deaths.
The Conservation Department and Fisheries New Zealand estimated that on average 336 dolphins, including two critically endangered Maui dolphins die from toxoplasmosis each year caused by cat faeces finding its way into the water.
But Professor Liz Slooten, from the Department of Zoology at Otago University, says these figures are nonsense. She talks to Susie Ferguson.
