Te Aitanga a Mahaki<br />
customary eel fisheries<br />
Scientist Ian Ruru and members <strong>of</strong> his hapu<br />
(Te Whanau a Kai) and iwi (Te Aitanga a<br />
Mahaki) are fast becoming experts on New<br />
Zealand freshwater eels in the lakes and<br />
waterways throughout the Waipaoa River catchment<br />
- and on its rich history <strong>of</strong> pa settlements and<br />
battles.<br />
They have surveyed eels in Lake Repongaere,<br />
Poverty Bay, looking at their size, age and growth<br />
rate, as well as checking past rainfall and river flow<br />
data to see if there were any clues to the recruitment<br />
success or failure <strong>of</strong> juvenile eels. This was all part <strong>of</strong><br />
a research project, funded by MFish, designed to<br />
assess the present status <strong>of</strong> eel stocks within the Te<br />
Aitanga a Mahaki iwi rohe.<br />
“We were very fortunate to have the support <strong>of</strong><br />
the Lake Repongaere owners, who saw the benefit <strong>of</strong><br />
assessing the current state <strong>of</strong> eels in their lake,” says<br />
Ian. The lake has always been an important mahinga<br />
kai for the generations who have lived around it and<br />
its commercial potential has recently been<br />
developed.<br />
The group also undertook a mapping exercise to<br />
assess and prioritise other eel populations within the<br />
rohe. This involved integrating the historical<br />
knowledge <strong>of</strong> Maori elders and customary fishing<br />
experts with a GIS database to identify key customary<br />
fishing areas for possible future assessments.<br />
“Te Aitanga a Mahaki Trust see this as a catalyst to<br />
the development <strong>of</strong> an Eel Management Plan for the<br />
entire Waipaoa River Catchment, as well as<br />
contributing to iwi and hapu research capabilities,”<br />
says Ian, adding that a successful partnership between<br />
Maori elders, landowners, scientists, iwi researchers<br />
and the wider community was an unforeseen but<br />
happy outcome.<br />
Ian counts himself lucky to have worked with Ben<br />
Chisnall, an eel expert from Te Awamutu. They both<br />
enjoy working with iwi and hope to develop a<br />
successful research partnership that provides useful<br />
tools to tangata whenua wishing to rebuild and<br />
enhance their natural resources.<br />
“The vision <strong>of</strong> Te Aitanga a Mahaki and the<br />
communities along the Waipaoa River is to ensure<br />
that the eel resource is managed sustainably and<br />
remains a taonga for our mokopuna,” says Ian. “We<br />
hope to continue the recording and utilising <strong>of</strong> Maori<br />
knowledge alongside scientific information to<br />
improve the understanding <strong>of</strong> cultural values and<br />
improved sustainable management <strong>of</strong> customary eel<br />
fisheries.”<br />
