Toady's post is all about Maui Dolphins. I have taken todays posts title from a Greenpeace article that can be found here. http://www.greenpeace.org/new-zealand/en/blog/the-worlds-slowest-emergency-response/blog/45166/
FishingGill net fishing has had an adverse effect on the Maui’s dolphin population.
Some groups in the fishing industry are against increased bans on set nets into waters further offshore and into harborus, and say there are other factors responsible for the decline in population, including disease, pollution, mining and natural predation.
DiseaseIn 2006 Brucella was identified in a dead Maui’s dolphin and DOC says this disease could 'have serious ramifications for the small Maui’s population. Brucella is a pathogen of terrestrial mammals that can cause late pregnancy abortion, and has been seen in a range of cetacean species elsewhere.
Recent post mortems on Hector’s and Maui’s have shown a 61 per cent infection rate of the parasite Toxoplasmosis. Two of the three Maui’s examined were killed by Toxoplasmosis. Toxoplasmosis is known to reduce fertility in livestock, with cats playing a key role in its spread. It is not known how Toxoplasmosis spread to Maui’s and Hector’s dolphins.
Set net banCurrently a trawling and set net ban stretches from Maunganui Bluff (north of Auckland) to Pariokariwa Point (north Taranaki), out to seven nautical miles from shore. Harbours along this stretch of coast do not have a set net ban.
After what MPI believed at the time in January 2012 was the capture of a Maui's dolphin off Taranaki, in June 2012 the New Zealand government announced an interim set net ban extension south around the Taranaki coast to Hawera and out to two nautical miles from shore, and placed observers to look for Maui's dolphins on all vessels setting nets out to seven nautical miles.
