An Otago university researcher has landed what could be a significant scientific catch using a 2km line and a blob of marmite. What's believe to be a new species of fish was lured from the depths of Lake Manapouri and Lake Te Anau last month. The fish is being DNA tested, and if confirmed as a new species it could reveal the secrets of a whole new eco-system. University of Otago Zoology researcher Doctor Roe Stuart discovered the fish and spoke to Lisa Owen.
