The following questions from schools are answered by Marine Ecologist Leigh Tait in web conference 3:

  1. Are there still problems and threats within our marine reserves?
  2. Have there been any noticeable effects from climate change in and around the harbour?
  3. How many fish, for example snapper, would be a sustainable recreational limit and should there also be a size limit for the big snapper, so fish bigger than 50cm also have to be let go?
  4. If there were an increasing number of sharks in the harbour, would that be good or bad?
  5. What new ideas do you have for how to protect marine areas, for example, should New Zealand have more marine reserves?
  6. Are there mangroves within the harbour? What do they do within the ecosystem?
